6ec96438ede86b1a00f80dff25027f5a876613a8 17-Oct-2011 Tanya Lattner <tonic@nondot.org> The comparison of two vectors should return a signed result. hasIntegerRepresentation() used to always return false for vectors, but since it was changed, it also
changed the return type of a compare of two unsigned vectors to be unsigned. This patch removes the check for hasIntegerRepresentation since its not needed and returns the appropriate signed type.
I added a new test case and updated exisiting test cases that assumed an unsigned result.

whether it is a constant expression, then again to get the value.

The goal is to postpone name lookup to instantiation time to be able to search into type dependent base classes.

This fixes a few errors when parsing MFC code with clang.
BTW clang trunk is now about 5 patches away to be able the parse the default wizard-generated MFC project.

OpenCL 6.2.1 says: "Implicit conversions between built-in vector data types are
disallowed." OpenCL 6.2.2 says: "Explicit casts between vector types are not
legal." For example:

uint4 u = (uint4)(1);
int4 i = u; // invalid implicit conversion

the lifetime of the block by copying it to the heap, or else we'll get
a dangling reference because the code working with the non-block-typed

There is some danger here, e.g. with assigning a block literal to an
unsafe variable, but, well, it's an unsafe variable.

a pointer-typed value anyway, so this fixit would not have actually
removed the warning.

variable initializers, arguments to function calls, and within conditional in
addition to the simpler cases of the operands to binary and unary operator)
while not being called--and triggering warnings--more than once for a given

b48f7c059e74cd5395ca542c1a96be16e42f3d80 26-Jul-2011 Kaelyn Uhrain <rikka@google.com> Expand array bounds checking to work in the presence of unary & and *,
and to work with pointer arithmetic in addition to array indexing.

The new pointer arithmetic porition of the array bounds checking can be
turned on by -Warray-bounds-pointer-arithmetic (and is off by default).

e5adf59d3a2699752d4981f03927459a38b2df18 15-Jul-2011 Richard Trieu <rtrieu@google.com> Remove warnings of constant operands of logical operators from template instantiations. Upon instantiation of template, value-dependent parameters are replaced by equivalent literals, so code like:

template<unsigned int A, unsigned int B> struct S {
int foo() {
int x = A && B;
}
}

will not warn on A && B on every instantiation. This will still warn on other cases inside templates, which will be caught on checking the template definition.

13b21be065e9feb0759303bd51b8e8653130f0fb 27-Jun-2011 Chandler Carruth <chandlerc@gmail.com> Factor out (some of) the checking for invalid forms of pointer
arithmetic into a couple of common routines. Use these to make the
messages more consistent in the various contexts, especially in terms of
consistently diagnosing binary operators with invalid types on both the
left- and right-hand side. Also, improve the grammar and wording of the
messages some, handling both two pointers and two (different) types.

The wording of function pointer arithmetic diagnostics still strikes me
as poorly phrased, and I worry this makes them slightly more awkward if
more consistent. I'm hoping to fix that with a follow-on patch and test
case that will also make them more helpful when a typedef or template
type parameter makes the type completely opaque.

Suggestions on better wording are very welcome, thanks to Richard Smith
for some initial help on that front.

necessary. We can try to optimize them later if they show up on

Change the output for -Wshift-overflow and
-Wshift-sign-overflow to an unsigned hexadecimal. It makes
more sense for looking at bits than a signed decimal does.
Also, change the diagnostic's wording from "overrides"
to "sets".

This uses a new optional argument in APInt::toString()
that adds the '0x' prefix to hexademical numbers.

This fixes PR 9651.

926df6cfabf3eaa4afc990c097fa4619b76a9b57 11-Jun-2011 Douglas Gregor <dgregor@apple.com> Implement Objective-C Related Result Type semantics.

Related result types apply Cocoa conventions to the type of message
sends and property accesses to Objective-C methods that are known to
always return objects whose type is the same as the type of the
receiving class (or a subclass thereof), such as +alloc and
-init. This tightens up static type safety for Objective-C, so that we
now diagnose mistakes like this:

t.m:4:10: warning: incompatible pointer types initializing 'NSSet *'
with an
expression of type 'NSArray *' [-Wincompatible-pointer-types]
NSSet *array = [[NSArray alloc] init];
^ ~~~~~~~~~~~~~~~~~~~~~~
/System/Library/Frameworks/Foundation.framework/Headers/NSObject.h:72:1:
note:
instance method 'init' is assumed to return an instance of its
receiver
type ('NSArray *')
- (id)init;
^

It also means that we get decent type inference when writing code in
Objective-C++0x:

auto array = [[NSMutableArray alloc] initWithObjects:@"one", @"two",nil];
// ^ now infers NSMutableArray* rather than id

e4d645cbe073042d8abc1a4eb600af4ff7a8dffb 27-May-2011 Chandler Carruth <chandlerc@gmail.com> Enhance Clang to start instantiating static data member definitions
within class templates when they are necessary to complete the type of
the member. The canonical example is code like:

template <typename T> struct S {
static const int arr[];
static const int x;
static int f();
};

template <typename T> const int S<T>::arr[] = { 1, 2, 3 };
template <typename T> const int S<T>::x = sizeof(arr) / sizeof(arr[0]);
template <typename T> int S<T>::f() { return x; }

int x = S<int>::f();

We need to instantiate S<T>::arr's definition to pick up its initializer
and complete the array type. This involves new code to specially handle
completing the type of an expression where the type alone is
insufficient. It also requires *updating* the expression with the newly
completed type. Fortunately, all the other infrastructure is already in
Clang to do the instantiation, do the completion, and prune out the
unused bits of code that result from this instantiation.

This addresses the initial bug in PR10001, and will be a step to
fleshing out other cases where we need to work harder to complete an
expression's type. Who knew we still had missing C++03 "features"?

itself was default-mapped to error, but can be downgraded, but we were
treating it in Sema like a hard error, silently dropping the call.

Instead, treat this problem like a warning, and do what the warning
says we do: abort at runtime. To do so, we fake up a __builtin_trap()
expression that gets evaluated as part of the argument.

312eadb832cab4497a069409954500d8192b8f0d 24-Apr-2011 Douglas Gregor <dgregor@apple.com> Implement a new identifier-classification scheme where Sema
performs name lookup for an identifier and resolves it to a
type/expression/template/etc. in the same step. This scheme is
intended to improve both performance (by reducing the number of
redundant name lookups for a given identifier token) and error
recovery (by giving Sema a chance to correct type names before the
parser has decided that the identifier isn't a type name). For
example, this allows us to properly typo-correct type names at the
beginning of a statement:

t.c:6:3: error: use of undeclared identifier 'integer'; did you mean
'Integer'?
integer *i = 0;
^~~~~~~
Integer
t.c:1:13: note: 'Integer' declared here
typedef int Integer;
^


Previously, we wouldn't give a Fix-It because the typo correction
occurred after the parser had checked whether "integer" was a type
name (via Sema::getTypeName(), which isn't allowed to typo-correct)
and therefore decided to parse "integer * i = 0" as an expression. By
typo-correcting earlier, we typo-correct to the type name Integer and
parse this as a declaration.

Moreover, in this context, we can also typo-correct identifiers to
keywords, e.g.,

t.c:7:3: error: use of undeclared identifier 'vid'; did you mean
'void'?
vid *p = i;
^~~
void

and recover appropriately.

Note that this is very much a work-in-progress. The new
Sema::ClassifyName is only used for expression-or-declaration
disambiguation in C at the statement level. The next steps will be to
make this work for the same disambiguation in C++ (where
functional-style casts make some trouble), then push it
further into the parser to eliminate more redundant name lookups.

Fixes <rdar://problem/7963833> for C and starts us down the path of
<rdar://problem/8172000>.

6b6b42aed07726178f61954ac6e51f47da00275c 19-Apr-2011 Argyrios Kyrtzidis <akyrtzi@gmail.com> We regard a function as 'unused' from the codegen perspective, so our warnings diverge from
gcc's unused warnings which don't get emitted if the function is referenced even in an unevaluated context
(e.g. in templates, sizeof, etc.). Also, saying that a function is 'unused' because it won't get codegen'ed
is somewhat misleading.

- Don't emit 'unused' warnings for functions that are referenced in any part of the user's code.
- A warning that an internal function/variable won't get emitted is useful though, so introduce
-Wunneeded-internal-declaration which will warn if a function/variable with internal linkage is not
"needed" ('used' from the codegen perspective), e.g:

static void foo() { }

template <int>
void bar() {
foo();
}

test.cpp:1:13: warning: function 'foo' is not needed and will not be emitted
static void foo() { }

This patch authored by Eric Niebler.

Many methods on the Sema class (e.g. ConvertPropertyForRValue) take Expr
pointers as in/out parameters (Expr *&). This is especially true for the
routines that apply implicit conversions to nodes in-place. This design is
workable only as long as those conversions cannot fail. If they are allowed
to fail, they need a way to report their failures. The typical way of doing
this in clang is to use an ExprResult, which has an extra bit to signal a
valid/invalid state. Returning ExprResult is de riguour elsewhere in the Sema
interface. We suggest changing the Expr *& parameters in the Sema interface
to ExprResult &. This increases interface consistency and maintainability.

This interface change is important for work supporting MS-style C++
properties. For reasons explained here
<http://lists.cs.uiuc.edu/pipermail/cfe-dev/2011-February/013180.html>,
seemingly trivial operations like rvalue/lvalue conversions that formerly
could not fail now can. (The reason is that given the semantics of the
feature, getter/setter method lookup cannot happen until the point of use, at
which point it may be found that the method does not exist, or it may have the
wrong type, or overload resolution may fail, or it may be inaccessible.)

The idea is that you can create a VarDecl with an unknown type, or a
FunctionDecl with an unknown return type, and it will still be valid to
access that object as long as you explicitly cast it at every use. I'm
still going back and forth about how I want to test this effectively, but
I wanted to go ahead and provide a skeletal implementation for the LLDB
folks' benefit and because it also improves some diagnostic goodness for
placeholder expressions.

0a0d2b179085a52c10402feebeb6db8b4d96a140 23-Mar-2011 Douglas Gregor <dgregor@apple.com> Implement a new 'availability' attribute, that allows one to specify
which versions of an OS provide a certain facility. For example,

void foo()
__attribute__((availability(macosx,introduced=10.2,deprecated=10.4,obsoleted=10.6)));

says that the function "foo" was introduced in 10.2, deprecated in
10.4, and completely obsoleted in 10.6. This attribute ties in with
the deployment targets (e.g., -mmacosx-version-min=10.1 specifies that
we want to deploy back to Mac OS X 10.1). There are several concrete
behaviors that this attribute enables, as illustrated with the
function foo() above:

- If we choose a deployment target >= Mac OS X 10.4, uses of "foo"
will result in a deprecation warning, as if we had placed
attribute((deprecated)) on it (but with a better diagnostic)
- If we choose a deployment target >= Mac OS X 10.6, uses of "foo"
will result in an "unavailable" warning (in C)/error (in C++), as
if we had placed attribute((unavailable)) on it
- If we choose a deployment target prior to 10.2, foo() is
weak-imported (if it is a kind of entity that can be weak
imported), as if we had placed the weak_import attribute on it.

Naturally, there can be multiple availability attributes on a
declaration, for different platforms; only the current platform
matters when checking availability attributes.

The only platforms this attribute currently works for are "ios" and
"macosx", since we already have -mxxxx-version-min flags for them and we
have experience there with macro tricks translating down to the
deprecated/unavailable/weak_import attributes. The end goal is to open
this up to other platforms, and even extension to other "platforms"
that are really libraries (say, through a #pragma clang
define_system), but that hasn't yet been designed and we may want to
shake out more issues with this narrower problem first.

Addresses <rdar://problem/6690412>.

As a drive-by bug-fix, if an entity is both deprecated and
unavailable, we only emit the "unavailable" diagnostic.

21206d5e3167d5e8066c005c1773afc80ff50ae6 24-Feb-2011 Chandler Carruth <chandlerc@gmail.com> Implement a warning for known shift overflows on constant shift
expressions. Consider the code:

int64_t i = 10 << 30;

This compiles fine, but most developers expect it to produce the value
for 10 gigs, not -2 gigs. This is actually undefined behavior because
the LHS is a signed integer type.

The warning is currently gated behind -Wshift-overflow.

There is a special case where only the sign bit is overridden that gets
a custom error message and is by default ignored. This case is much less
likely to cause observed buggy behavior, it's just undefined behavior
according to the spec. This warning can be enabled with
-Wshift-sign-overflow.

Original patch by Oleg Slezberg, with style tweaks and some correctness
fixes by me.

56ca35d396d8692c384c785f9aeebcf22563fe1e 17-Feb-2011 John McCall <rjmccall@apple.com> Change the representation of GNU ?: expressions to use a different expression
class and to bind the shared value using OpaqueValueExpr. This fixes an
unnoticed problem with deserialization of these expressions where the
deserialized form would lose the vital pointer-equality trait; or rather,
it fixes it because this patch also does the right thing for deserializing
OVEs.

Change OVEs to not be a "temporary object" in the sense that copy elision is
permitted.

This new representation is not totally unawkward to work with, but I think
that's really part and parcel with the semantics we're modelling here. In
particular, it's much easier to fix things like the copy elision bug and to
make the CFG look right.

I've tried to update the analyzer to deal with this in at least some
obvious cases, and I think we get a much better CFG out, but the printing
of OpaqueValueExprs probably needs some work.

controling whether it is on by default, it is always on by default.

Original patch contributed by Richard Trieu (@ Google), I fixed some
style issues, and cleaned it up for submission.

ad8dcf4a9df0e24051dc31bf9e6f3cd138a34298 17-Feb-2011 Chris Lattner <sabre@nondot.org> Step #1/N of implementing support for __label__: split labels into
LabelDecl and LabelStmt. There is a 1-1 correspondence between the
two, but this simplifies a bunch of code by itself. This is because
labels are the only place where we previously had references to random
other statements, causing grief for AST serialization and other stuff.

This does cause one regression (attr(unused) doesn't silence unused
label warnings) which I'll address next.

This does fix some minor bugs:
1. "The only valid attribute " diagnostic was capitalized.
2. Various diagnostics printed as ''labelname'' instead of 'labelname'
3. This reduces duplication of label checking between functions and blocks.

Review appreciated, particularly for the cindex and template bits.

- BlockDeclRefExprs always store VarDecls
- BDREs no longer store copy expressions
- BlockDecls now store a list of captured variables, information about
how they're captured, and a copy expression if necessary

With that in hand, change IR generation to use the captures data in
blocks instead of walking the block independently.

Additionally, optimize block layout by emitting fields in descending
alignment order, with a heuristic for filling in words when alignment
of the end of the block header is insufficient for the most aligned
field.

711c52bb20d0c69063b52a99826fb7d2835501f1 05-Jan-2011 John McCall <rjmccall@apple.com> Refactor the application of type attributes so that attributes from
the declaration-specifiers and on the declarator itself are moved
to the appropriate declarator chunk. This permits a greatly
simplified model for how to apply these attributes, as well as
allowing a much more efficient query for the GC attribute.
Now all qualifier queries follow the same basic strategy of
"local qualifiers, local qualifiers on the canonical type,
then look through arrays". This can be easily optimized by
changing the canonical qualified-array-type representation.

Do not process type attributes as decl attributes on declarations
with declarators.

When computing the type of a block, synthesize a prototype
function declarator chunk if the decl-spec type was not a
function. This simplifies the logic for building block signatures.

Change the logic which inserts an objc_read_weak on a block
literal to only fire if the block has a __weak __block variable,
rather than if the return type of the block is __weak qualified,
which is not actually a sensible thing to ask.

int x = 42;

The warning avoids macro expansions, templates, user-defined assignment

The common (mis-)use of this code pattern is to silence unused variable
warnings, but a more idiomatic way of doing that is '(void)x;'.

replacement in cases where the StmtExpr consists precisely of the self

0827408865e32789e0ec4b8113a302ccdc531423 15-Dec-2010 Argyrios Kyrtzidis <akyrtzi@gmail.com> Fix diagnostic pragmas.

Diagnostic pragmas are broken because we don't keep track of the diagnostic state changes and we only check the current/latest state.
Problems manifest if a diagnostic is emitted for a source line that has different diagnostic state than the current state; this can affect
a lot of places, like C++ inline methods, template instantiations, the lexer, etc.

Fix the issue by having the Diagnostic object keep track of the source location of the pragmas so that it is able to know what is the diagnostic state at any given source location.

Fixes rdar://8365684.

bebbe0d9b7568ce43a464286bee49429489ef483 15-Dec-2010 Douglas Gregor <dgregor@apple.com> Variadic templates: extend the Expr class with a bit that specifies
whether the expression contains an unexpanded parameter pack, in the
same vein as the changes to the Type hierarchy. Compute this bit
within all of the Expr subclasses.

This change required a bunch of reshuffling of dependency
calculations, mainly to consolidate them inside the constructors and
to fuse multiple loops that iterate over arguments to determine type
dependence, value dependence, and (now) containment of unexpanded
parameter packs.

Again, testing is painfully sparse, because all of the diagnostics
will change and it is more important to test the to-be-written visitor
that collects unexpanded parameter packs.

f6a1648197562e0b133440d612d9af297d0a86cc 04-Dec-2010 John McCall <rjmccall@apple.com> Although we currently have explicit lvalue-to-rvalue conversions, they're
not actually frequently used, because ImpCastExprToType only creates a node
if the types differ. So explicitly create an ICE in the lvalue-to-rvalue
conversion code in DefaultFunctionArrayLvalueConversion() as well as several
other new places, and consistently deal with the consequences throughout the
compiler.

In addition, introduce a new cast kind for loading an ObjCProperty l-value,
and make sure we emit those nodes whenever an ObjCProperty l-value appears
that's not on the LHS of an assignment operator.

This breaks a couple of rewriter tests, which I've x-failed until future
development occurs on the rewriter.

if x is an instance method.
- Anonymous struct/union paths pick up value kind the same way that
normal member accesses do; extract out a common code path for this.

Enable the value-kind assertion, now that it passes self-host.

A new AST node is introduced:
def IndirectField : DDecl<Value>;
IndirectFields are injected into the anonymous's parent scope and chain back to
the original field. Name lookup for anonymous entities now result in an
IndirectFieldDecl instead of a FieldDecl.
There is no functionality change, the code generated should be the same.

Currently we're not using these for much, but I aim to switch

since this is safe. This way we avoid a big source of such warnings which in this case are practically useless.

Note that we don't handle *all* cases where precedence wouldn't matter because of constants since
this is a bit costly to check, and IMO clarifying precedence with parentheses is good for
readability in general.

That bug concerned the well-formedness of code such as (&ovl)(a, b,
c). GCC rejects the code, while EDG accepts it. On further study of the
standard, I see no support for EDG's position: in particular, C++
[over.over] does not list this as a context where we can take the
address of an overloaded function, C++ [over.call.func] does not
reference the address-of operator at any point, and C++ [expr.call]
claims that the function argument in a call is either a function
lvalue or a pointer-to-function; (&ovl) is neither.

9b623639378d53a675921ddfa7316034d571881e 13-Oct-2010 Douglas Gregor <dgregor@apple.com> Introduce support for emitting diagnostics (warnings + their notes)
that are suppressed during template argument deduction. This change
queues diagnostics computed during template argument deduction. Then,
if the resulting function template specialization or partial
specialization is chosen by overload resolution or partial ordering
(respectively), we will emit the queued diagnostics at that point.

This addresses most of PR6784. However, the check for unnamed/local
template arguments (which existed before this change) is still only
skin-deep, and needs to be extended to look deeper into types. It must
be improved to finish PR6784.

used in the default function argument as "used". Instead, when we
actually use the default argument, make another pass over the
expression to mark any used declarations as "used" at that point. This
addresses two kinds of related problems:

1) We were marking some declarations "used" that shouldn't be,
because we were marking them too eagerly.
2) We were failing to mark some declarations as "used" when we
should, if the first time it was instantiated happened to be an
unevaluated context, we wouldn't mark them again at a later point.

I've also added a potentially-handy visitor class template
EvaluatedExprVisitor, which only visits the potentially-evaluated
subexpressions of an expression. I bet this would have been useful for
noexcept...

Doug, please review. I think this follows your latest suggestion, and it ended
up remarkably cleaner than I anticipated. Also let me know if similar logic
should be followed for destructors and copy-constructors.

This takes some trickery since CastExpr has subclasses (and indeed,
is abstract).

Also, smoosh the CastKind into the bitfield from Expr.

Drops two words of storage from Expr in the common case of expressions
which don't need inheritance paths. Avoids a separate allocation and
another word of overhead in cases needing inheritance paths. Also has
the advantage of not leaking memory, since destructors for AST nodes are
never run.

6398235d7890a81b785ea5af3b6e66d86bf184cc 13-Jul-2010 Douglas Gregor <dgregor@apple.com> Whenever we're creating an expression that is typically an rvalue
(e.g., a call, cast, etc.), immediately adjust the expression's type
to strip cv-qualifiers off of all non-class types (in C++) or all
types (in C). This effectively extends my previous fix for PR7463,
which was restricted to calls, to other kinds of expressions within
similar characteristics. I've audited every use of
getNonReferenceType() in the code base, switching to the newly-renamed
getNonLValueExprType() where necessary.

Big thanks to Eli for pointing out just how incomplete my original fix
for PR7463 actually was. We've been handling cv-qualifiers on rvalues
wrong for a very, very long time. Fixes PR7463.

strip cv-qualifiers from the expression's type when the language calls
for it: in C, that's all the time, while C++ only does it for
non-class types.

Centralized the computation of the call expression type in
QualType::getCallResultType() and some helper functions in other nodes
(FunctionDecl, ObjCMethodDecl, FunctionType), and updated all relevant
callers of getResultType() to getCallResultType().

Fixes PR7598 and PR7463, along with a bunch of getResultType() call
sites that weren't stripping references off the result type (nothing
stripped cv-qualifiers properly before this change).

around by exempting enums from the check, but this doesn't handle a lot of

2d6b0e94db30c0e2754d270753c6f75478e451bf 22-May-2010 Douglas Gregor <dgregor@apple.com> Improve our handling of reference binding for subobjects of
temporaries. There are actually several interrelated fixes here:

- When converting an object to a base class, it's only an lvalue
cast when the original object was an lvalue and we aren't casting
pointer-to-derived to pointer-to-base. Previously, we were
misclassifying derived-to-base casts of class rvalues as lvalues,
causing various oddities (including problems with reference binding
not extending the lifetimes of some temporaries).

- Teach the code for emitting a reference binding how to look
through no-op casts and parentheses directly, since
Expr::IgnoreParenNoOpCasts is just plain wrong for this. Also, make
sure that we properly look through multiple levels of indirection
from the temporary object, but destroy the actual temporary object;
this fixes the reference-binding issue mentioned above.

- Teach Objective-C message sends to bind the result as a temporary
when needed. This is actually John's change, but it triggered the
reference-binding problem above, so it's included here. Now John
can actually test his return-slot improvements.

1fd6d44d7ca97631497551bbf98866263143d706 22-May-2010 Douglas Gregor <dgregor@apple.com> Improve parser recovery when we encounter a dependent template name
that is missing the 'template' keyword, e.g.,

t->getAs<T>()

where getAs is a member of an unknown specialization. C++ requires
that we treat "getAs" as a value, but that would fail to parse since T
is the name of a type. We would then fail at the '>', since a type
cannot be followed by a '>'.

This is a very common error for C++ programmers to make, especially
since GCC occasionally allows it when it shouldn't (as does Visual
C++). So, when we are in this case, we use tentative parsing to see if
the tokens starting at "<" can only be parsed as a template argument
list. If so, we produce a diagnostic with a fix-it that states that
the 'template' keyword is needed:

test/SemaTemplate/dependent-template-recover.cpp:5:8: error: 'template' keyword
is required to treat 'getAs' as a dependent template name
t->getAs<T>();
^
template

This is just a start of this patch; I'd like to apply the same
approach to everywhere that a template-id with dependent template name
can be parsed.

lookups, but this didn't trigger code paths that need it. This removes part of
an optimization that re-uses the template name lookup done by the parser to
determine if explicit template arguments actually form a template-id.
Unfortunately the technique for avoiding the duplicate lookup lost needed data
such as the class context in which the lookup succeeded.

c12c5bba6ceb6acd4e51e7a0fc03257da9cfd44e 15-May-2010 John McCall <rjmccall@apple.com> Substantially alter the design of the Objective C type AST by introducing
ObjCObjectType, which is basically just a pair of
one of {primitive-id, primitive-Class, user-defined @class}
with
a list of protocols.
An ObjCObjectPointerType is therefore just a pointer which always points to
one of these types (possibly sugared). ObjCInterfaceType is now just a kind
of ObjCObjectType which happens to not carry any protocols.

Alter a rather large number of use sites to use ObjCObjectType instead of
ObjCInterfaceType. Store an ObjCInterfaceType as a pointer on the decl rather
than hashing them in a FoldingSet. Remove some number of methods that are no
longer used, at least after this patch.

By simplifying ObjCObjectPointerType, we are now able to easily remove and apply
pointers to Objective-C types, which is crucial for a certain kind of ObjC++
metaprogramming common in WebKit.

6fb745bdf1ff1e32caf07e42093a7920726892c1 13-May-2010 Douglas Gregor <dgregor@apple.com> Rework when and how vtables are emitted, by tracking where vtables are
"used" (e.g., we will refer to the vtable in the generated code) and
when they are defined (i.e., because we've seen the key function
definition). Previously, we were effectively tracking "potential
definitions" rather than uses, so we were a bit too eager about emitting
vtables for classes without key functions.

The new scheme:
- For every use of a vtable, Sema calls MarkVTableUsed() to indicate
the use. For example, this occurs when calling a virtual member
function of the class, defining a constructor of that class type,
dynamic_cast'ing from that type to a derived class, casting
to/through a virtual base class, etc.
- For every definition of a vtable, Sema calls MarkVTableUsed() to
indicate the definition. This happens at the end of the translation
unit for classes whose key function has been defined (so we can
delay computation of the key function; see PR6564), and will also
occur with explicit template instantiation definitions.
- For every vtable defined/used, we mark all of the virtual member
functions of that vtable as defined/used, unless we know that the key
function is in another translation unit. This instantiates virtual
member functions when needed.
- At the end of the translation unit, Sema tells CodeGen (via the
ASTConsumer) which vtables must be defined (CodeGen will define
them) and which may be used (for which CodeGen will define the
vtables lazily).

From a language perspective, both the old and the new schemes are
permissible: we're allowed to instantiate virtual member functions
whenever we want per the standard. However, all other C++ compilers
were more lazy than we were, and our eagerness was both a performance
issue (we instantiated too much) and a portability problem (we broke
Boost test cases, which now pass).

Notes:
(1) There's a ton of churn in the tests, because the order in which
vtables get emitted to IR has changed. I've tried to isolate some of
the larger tests from these issues.
(2) Some diagnostics related to
implicitly-instantiated/implicitly-defined virtual member functions
have moved to the point of first use/definition. It's better this
way.
(3) I could use a review of the places where we MarkVTableUsed, to
see if I missed any place where the language effectively requires a
vtable.

Fixes PR7114 and PR6564.

323ed74658bc8375278eabf074b4777458376540 06-May-2010 John McCall <rjmccall@apple.com> Rearchitect -Wconversion and -Wsign-compare. Instead of computing them
"bottom-up" when implicit casts and comparisons are inserted, compute them
"top-down" when the full expression is finished. Makes it easier to
coordinate warnings and thus implement -Wconversion for signedness
conversions without double-warning with -Wsign-compare. Also makes it possible
to realize that a signedness conversion is okay because the context is
performing the inverse conversion. Also simplifies some logic that was
trying to calculate the ultimate comparison/result type and getting it wrong.
Also fixes a problem with the C++ explicit casts which are often "implemented"
in the AST with a series of implicit cast expressions.

06a9f3680d22529a2fcf20c52d71cf221d99d910 01-May-2010 Douglas Gregor <dgregor@apple.com> Complete reimplementation of the synthesis for implicitly-defined copy
assignment operators.

Previously, Sema provided type-checking and template instantiation for
copy assignment operators, then CodeGen would synthesize the actual
body of the copy constructor. Unfortunately, the two were not in sync,
and CodeGen might pick a copy-assignment operator that is different
from what Sema chose, leading to strange failures, e.g., link-time
failures when CodeGen called a copy-assignment operator that was not
instantiation, run-time failures when copy-assignment operators were
overloaded for const/non-const references and the wrong one was
picked, and run-time failures when by-value copy-assignment operators
did not have their arguments properly copy-initialized.

This implementation synthesizes the implicitly-defined copy assignment
operator bodies in Sema, so that the resulting ASTs encode exactly
what CodeGen needs to do; there is no longer any special code in
CodeGen to synthesize copy-assignment operators. The synthesis of the
body is relatively simple, and we generate one of three different
kinds of copy statements for each base or member:

- For a class subobject, call the appropriate copy-assignment
operator, after overload resolution has determined what that is.
- For an array of scalar types or an array of class types that have
trivial copy assignment operators, construct a call to
__builtin_memcpy.
- For an array of class types with non-trivial copy assignment
operators, synthesize a (possibly nested!) for loop whose inner
statement calls the copy constructor.
- For a scalar type, use built-in assignment.

This patch fixes at least a few tests cases in Boost.Spirit that were
failing because CodeGen picked the wrong copy-assignment operator
(leading to link-time failures), and I suspect a number of undiagnosed
problems will also go away with this change.

Some of the diagnostics we had previously have gotten worse with this
change, since we're going through generic code for our
type-checking. I will improve this in a subsequent patch.

8ecdb65716cd7914ffb2eeee993fa9039fcd31e8 29-Apr-2010 Douglas Gregor <dgregor@apple.com> Completely reimplement __builtin_offsetof, based on a patch by Roberto
Amadini.

This change introduces a new expression node type, OffsetOfExpr, that
describes __builtin_offsetof. Previously, __builtin_offsetof was
implemented using a unary operator whose subexpression involved
various synthesized array-subscript and member-reference expressions,
which was ugly and made it very hard to instantiate as a
template. OffsetOfExpr represents the AST more faithfully, with proper
type source information and a more compact representation.

OffsetOfExpr also has support for dependent __builtin_offsetof
expressions; it can be value-dependent, but will never be
type-dependent (like sizeof or alignof). This commit introduces
template instantiation for __builtin_offsetof as well.

There are two major caveats to this patch:

1) CodeGen cannot handle the case where __builtin_offsetof is not a
constant expression, so it produces an error. So, to avoid
regressing in C, we retain the old UnaryOperator-based
__builtin_offsetof implementation in C while using the shiny new
OffsetOfExpr implementation in C++. The old implementation can go
away once we have proper CodeGen support for this case, which we
expect won't cause much trouble in C++.

2) __builtin_offsetof doesn't work well with non-POD class types,
particularly when the designated field is found within a base
class. I will address this in a subsequent patch.

Fixes PR5880 and a bunch of assertions when building Boost.Python
tests.

04badcf84c8d504d8491c7c7e29b58f52cb16640 21-Apr-2010 Douglas Gregor <dgregor@apple.com> Overhaul the AST representation of Objective-C message send
expressions, to improve source-location information, clarify the
actual receiver of the message, and pave the way for proper C++
support. The ObjCMessageExpr node represents four different kinds of
message sends in a single AST node:

1) Send to a object instance described by an expression (e.g., [x method:5])
2) Send to a class described by the class name (e.g., [NSString method:5])
3) Send to a superclass class (e.g, [super method:5] in class method)
4) Send to a superclass instance (e.g., [super method:5] in instance method)

Previously these four cases where tangled together. Now, they have
more distinct representations. Specific changes:

1) Unchanged; the object instance is represented by an Expr*.

2) Previously stored the ObjCInterfaceDecl* referring to the class
receiving the message. Now stores a TypeSourceInfo* so that we know
how the class was spelled. This both maintains typedef information
and opens the door for more complicated C++ types (e.g., dependent
types). There was an alternative, unused representation of these
sends by naming the class via an IdentifierInfo *. In practice, we
either had an ObjCInterfaceDecl *, from which we would get the
IdentifierInfo *, or we fell into the case below...

3) Previously represented by a class message whose IdentifierInfo *
referred to "super". Sema and CodeGen would use isStr("super") to
determine if they had a send to super. Now represented as a
"class super" send, where we have both the location of the "super"
keyword and the ObjCInterfaceDecl* of the superclass we're
targetting (statically).

4) Previously represented by an instance message whose receiver is a
an ObjCSuperExpr, which Sema and CodeGen would check for via
isa<ObjCSuperExpr>(). Now represented as an "instance super" send,
where we have both the location of the "super" keyword and the
ObjCInterfaceDecl* of the superclass we're targetting
(statically). Note that ObjCSuperExpr only has one remaining use in
the AST, which is for "super.prop" references.

The new representation of ObjCMessageExpr is 2 pointers smaller than
the old one, since it combines more storage. It also eliminates a leak
when we loaded message-send expressions from a precompiled header. The
representation also feels much cleaner to me; comments welcome!

This patch attempts to maintain the same semantics we previously had
with Objective-C message sends. In several places, there are massive
changes that boil down to simply replacing a nested-if structure such
as:

if (message has a receiver expression) {
// instance message
if (isa<ObjCSuperExpr>(...)) {
// send to super
} else {
// send to an object
}
} else {
// class message
if (name->isStr("super")) {
// class send to super
} else {
// send to class
}
}

with a switch

switch (E->getReceiverKind()) {
case ObjCMessageExpr::SuperInstance: ...
case ObjCMessageExpr::Instance: ...
case ObjCMessageExpr::SuperClass: ...
case ObjCMessageExpr::Class:...
}

There are quite a few places (particularly in the checkers) where
send-to-super is effectively ignored. I've placed FIXMEs in most of
them, and attempted to address send-to-super in a reasonable way. This
could use some review.

LookupInObjCMethod. Doing so allows all sorts of invalid code
to slip through to codegen. This patch does not change the
AST representation of super, though that would now be a natural
thing to do since it can only be in the receiver position and
in the base of a ObjCPropertyRefExpr.

There are still several ugly areas handling super in the parser,
but this is definitely a step in the right direction.

destination type for initialization, assignment, parameter-passing,

wording for diagnostics such as

t.c:2:9: warning: initializing 'char const [2]' discards qualifiers,
expected 'char *' [-pedantic]
char *name = __func__;
^ ~~~~~~~~

We're not initializing a 'char const [2]', we're initializing a 'char
*' with an expression of type 'char const [2]'. Similar problems
existed for other diagnostics in this area, so I've normalized them all
with more precise descriptive text to say what we're
initializing/converting/assigning/etc. from and to. The warning for
the code above is now:

t.c:2:9: warning: initializing 'char *' from an expression of type
'char const [2]' discards qualifiers [-pedantic]

9ea9bdbc14374f7bacdb50d3e52c664ff12150ff 02-Mar-2010 Douglas Gregor <dgregor@apple.com> Keep an explicit stack of function and block scopes, each element of
which has the label map, switch statement stack, etc. Previously, we
had a single set of maps in Sema (for the function) along with a stack
of block scopes. However, this lead to funky behavior with nested
functions, e.g., in the member functions of local classes.

The explicit-stack approach is far cleaner, and we retain a 1-element
cache so that we're not malloc/free'ing every time we enter a
function. Fixes PR6382.

Also, tweaked the unused-variable warning suppression logic to look at
errors within a given Scope rather than within a given function. The
prior code wasn't looking at the right number-of-errors count when
dealing with blocks, since the block's count would be deallocated
before we got to ActOnPopScope. This approach works with nested
blocks/functions, and gives tighter error recovery.

b2cb1cbd727469e1567a6f2535895e6b64e12c35 25-Feb-2010 Douglas Gregor <dgregor@apple.com> When computing the composite pointer type for relational comparisons,
equality comparisons, and conditional operators, produce a composite
pointer type with the appropriate additional "const" qualifiers if the
pointer types would otherwise be incompatible. This is a small
extension (also present in GCC and EDG in a slightly different form)
that permits code like:

void** i; void const** j;
i == j;

with the following extwarn:

t.cpp:5:5: warning: comparison of distinct pointer types ('void **' and
'void const **') uses non-standard composite pointer type
'void const *const *' [-pedantic]
i == j;

Fixes PR6346, and I'll be filing a core issue about this with the C++

pseudo-destructor expressions, and builds the CXXPseudoDestructorExpr
node directly. Currently, this only affects pseudo-destructor
expressions when they are parsed, but not after template
instantiation. That's coming next...

Improve parsing of pseudo-destructor-names. When parsing the
nested-name-specifier and we hit the sequence of tokens X :: ~, query
the actual module to determine whether X is a type-name (in which case
the X :: is part of the pseudo-destructor-name but not the
nested-name-specifier) or not (in which case the X :: is part of the
nested-name-specifier).

to initializer expressions in an array allocated using ASTContext.

This plugs a memory leak when ASTContext uses a BumpPtrAllocator to
allocate memory for AST nodes.

In my mind this isn't an ideal solution; it would be nice to have
a general "vector"-like class that allocates memory using ASTContext,
but whose guts could be separated from the methods of InitListExpr
itself. I haven't gone and taken this approach yet because it isn't
clear yet if we'll eventually want an alternate solution for recylcing
memory using by InitListExprs as we are constructing the ASTs.

a873dfc9e7314681bb37efd9ab185045de121e43 03-Feb-2010 Douglas Gregor <dgregor@apple.com> Implement the lvalue-to-rvalue conversion where needed. The
lvalue-to-rvalue conversion adjusts lvalues of qualified, non-class
type to rvalue expressions of the unqualified variant of that
type. For example, given:

const int i;
(void)(i + 17);

the lvalue-to-rvalue conversion for the subexpression "i" will turn it
from an lvalue expression (a DeclRefExpr) with type 'const int' into
an rvalue expression with type 'int'. Both C and C++ mandate this
conversion, and somehow we've slid through without implementing it.

We now have both DefaultFunctionArrayConversion and
DefaultFunctionArrayLvalueConversion, and which gets used depends on
whether we do the lvalue-to-rvalue conversion or not. Generally, we do
the lvalue-to-rvalue conversion, but there are a few notable
exceptions:
- the left-hand side of a '.' operator
- the left-hand side of an assignment
- a C++ throw expression
- a subscript expression that's subscripting a vector

Making this change exposed two issues with blocks:
- we were deducing const-qualified return types of non-class type
from a block return, which doesn't fit well
- we weren't always setting the known return type of a block when it
was provided with the ^return-type syntax

Fixes the current Clang-on-Clang compile failure and PR6076.

1309f9a3b225ea846e5822691c39a77423125505 25-Jan-2010 Ted Kremenek <kremenek@apple.com> Split libAnalysis into two libraries: libAnalysis and libChecker.

(1) libAnalysis is a generic analysis library that can be used by
Sema. It defines the CFG, basic dataflow analysis primitives, and
inexpensive flow-sensitive analyses (e.g. LiveVariables).

(2) libChecker contains the guts of the static analyzer, incuding the
path-sensitive analysis engine and domain-specific checks.

Now any clients that want to use the frontend to build their own tools
don't need to link in the entire static analyzer.

This change exposes various obvious cleanups that can be made to the
layout of files and headers in libChecker. More changes pending. :)

This change also exposed a layering violation between AnalysisContext
and MemRegion. BlockInvocationContext shouldn't explicitly know about
BlockDataRegions. For now I've removed the BlockDataRegion* from
BlockInvocationContext (removing context-sensitivity; although this
wasn't used yet). We need to have a better way to extend
BlockInvocationContext (and any LocationContext) to add
context-sensitivty.

48026d26fb58e413544874eead5491b1452e2ebf 11-Jan-2010 Douglas Gregor <dgregor@apple.com> Implement name lookup for conversion function template specializations
(C++ [temp.mem]p5-6), which involves template argument deduction based
on the type named, e.g., given

struct X { template<typename T> operator T*(); } x;

when we call

x.operator int*();

we perform template argument deduction to determine that T=int. This
template argument deduction is needed for template specialization and
explicit instantiation, e.g.,

template<> X::operator float*() { /* ... */ }

and when calling or otherwise naming a conversion function (as in the
first example).

This fixes PR5742 and PR5762, although there's some remaining ugliness
that's causing out-of-line definitions of conversion function
templates to fail. I'll look into that separately.

member function thereof), perform the template instantiation each time
the default argument is needed. This ensures that
(1) We get different CXXTemporary objects for each instantiation, and
(2) Any other instantiations or definitions triggered by the
instantiation of the default argument expression are guaranteed to
happen; previously, they might have been suppressed, e.g., because
they happened in an unevaluated context.

This fixes the majority of PR5810. However, it does not address the
problem where we may have multiple uses of the same CXXTemporary
within an expression when the temporary came from a non-instantiated
default argument expression.

99a2e600f9e2e51d3ce10fb6f27191677ac65b2a 16-Dec-2009 Douglas Gregor <dgregor@apple.com> Switch the C++ new expression over to InitializationSequence, rather
than using its own partial implementation of initialization.

Switched CheckInitializerTypes over to
InitializedEntity/InitializationKind, to help move us closer to
InitializationSequence.

Added InitializedEntity::getName() to retrieve the name of the entity,
for diagnostics that care about such things.

Implemented support for default initialization in
InitializationSequence.

Clean up the determination of the "source expressions" for an
initialization sequence in InitializationSequence::Perform.

Taught CXXConstructExpr to store more location information.

aa81e1658d87b9011125c632aa902d154ae4b02c 01-Dec-2009 John McCall <rjmccall@apple.com> Rework how we support C++ implicit member accesses. If we can resolve an
implicit member access to a specific declaration, go ahead and create
it as a DeclRefExpr or a MemberExpr (with implicit CXXThisExpr base) as
appropriate. Otherwise, create an UnresolvedMemberExpr or
DependentScopeMemberExpr with a null base expression.

By representing implicit accesses directly in the AST, we get the ability
to correctly delay the decision about whether it's actually an instance
member access or not until resolution is complete. This permits us
to correctly avoid diagnosing the 'problem' of 'MyType::foo()'
where the relationship to the type isn't really known until instantiation.

operand of an addressof operator, and so we should not treat it as an abstract
member-pointer expression and therefore suppress the implicit member access.

This is really a well-formedness constraint on expressions: a DeclRefExpr of
a FieldDecl or a non-static CXXMethodDecl (or template thereof, or unresolved
collection thereof) should not be allowed in an arbitrary location in the AST.
Arguably it shouldn't be allowed anywhere and we should have a different expr
node type for this. But unfortunately we don't have a good way of enforcing
this kind of constraint right now.

into pretty much everything about overload resolution in order to wean
BuildDeclarationNameExpr off LookupResult::getAsSingleDecl(). Replace
UnresolvedFunctionNameExpr with UnresolvedLookupExpr, which generalizes the
idea of a non-member lookup that we haven't totally resolved yet, whether by
overloading, argument-dependent lookup, or (eventually) the presence of
a function template in the lookup results.

Incidentally fixes a problem with argument-dependent lookup where we were
still performing ADL even when the lookup results contained something from
a block scope.

Incidentally improves a diagnostic when using an ObjC ivar from a class method.
This just fell out from rewriting BuildDeclarationNameExpr's interaction with
lookup, and I'm too apathetic to break it out.

The only remaining uses of OverloadedFunctionDecl that I know of are in
TemplateName and MemberExpr.

will naturally strip the aliases off.

a4923eb7c4b04d360cb2747641a5e92818edf804 16-Nov-2009 Douglas Gregor <dgregor@apple.com> First part of changes to eliminate problems with cv-qualifiers and
sugared types. The basic problem is that our qualifier accessors
(getQualifiers, getCVRQualifiers, isConstQualified, etc.) only look at
the current QualType and not at any qualifiers that come from sugared
types, meaning that we won't see these qualifiers through, e.g.,
typedefs:

typedef const int CInt;
typedef CInt Self;

Self.isConstQualified() currently returns false!

Various bugs (e.g., PR5383) have cropped up all over the front end due
to such problems. I'm addressing this problem by splitting each
qualifier accessor into two versions:

- the "local" version only returns qualifiers on this particular
QualType instance
- the "normal" version that will eventually combine qualifiers from this
QualType instance with the qualifiers on the canonical type to
produce the full set of qualifiers.

This commit adds the local versions and switches a few callers from
the "normal" version (e.g., isConstQualified) over to the "local"
version (e.g., isLocalConstQualified) when that is the right thing to
do, e.g., because we're printing or serializing the qualifiers. Also,
switch a bunch of

Context.getCanonicalType(T1).getUnqualifiedType() == Context.getCanonicalType(T2).getQualifiedType()

expressions over to

Context.hasSameUnqualifiedType(T1, T2)

handling template template parameters properly. This refactoring:

- Parses template template arguments as id-expressions, representing
the result of the parse as a template name (Action::TemplateTy)
rather than as an expression (lame!).

- Represents all parsed template arguments via a new parser-specific
type, ParsedTemplateArgument, which stores the kind of template
argument (type, non-type, template) along with all of the source
information about the template argument. This replaces an ad hoc
set of 3 vectors (one for a void*, which was either a type or an
expression; one for a bit telling whether the first was a type or
an expression; and one for a single source location pointing at
the template argument).

- Moves TemplateIdAnnotation into the new Parse/Template.h. It never
belonged in the Basic library anyway.

Also make the comparison test cases much more rigorous, and have them expose

didn't find any functions to save until instantiation time. Now, that
code builds a BinaryOperator or CompoundAssignOperator rather than a
CXXOperatorCallExpr, to save some space.

54abf7d4fa3123b8324c09d2a4dfb789fd818403 04-Nov-2009 John McCall <rjmccall@apple.com> Change our basic strategy for avoiding deprecation warnings when the decl use
appears in a deprecated context. In the new strategy, we emit the warnings
as usual unless we're currently parsing a declaration, where "declaration" is
restricted to mean a decl group or a few special cases in Objective C. If
we *are* parsing a declaration, we queue up the deprecation warnings until
the declaration has been completely parsed, and then emit them only if the
decl is not deprecated.
We also standardize the bookkeeping for deprecation so as to avoid special cases.

a2813cec2605ce7878d1b13471d685f689b251af 23-Oct-2009 Douglas Gregor <dgregor@apple.com> Eliminate QualifiedDeclRefExpr, which captured the notion of a
qualified reference to a declaration that is not a non-static data
member or non-static member function, e.g.,

namespace N { int i; }
int j = N::i;

Instead, extend DeclRefExpr to optionally store the qualifier. Most
clients won't see or care about the difference (since
QualifierDeclRefExpr inherited DeclRefExpr). However, this reduces the
number of top-level expression types that clients need to cope with,
brings the implementation of DeclRefExpr into line with MemberExpr,
and simplifies and unifies our handling of declaration references.

Extended DeclRefExpr to (optionally) store explicitly-specified
template arguments. This occurs when naming a declaration via a
template-id (which will be stored in a TemplateIdRefExpr) that,
following template argument deduction and (possibly) overload
resolution, is replaced with a DeclRefExpr that refers to a template
specialization but maintains the template arguments as written.

251b4ff2578e26959a4c036140ccd61c5e9292f2 08-Oct-2009 Douglas Gregor <dgregor@apple.com> For instantiations of static data members of class templates, keep
track of the kind of specialization or instantiation. Also, check the
scope of the specialization and ensure that a specialization
declaration without an initializer is not a definition.

3307475eb0dd6e5d88be9392ea8247d0b6b812df 30-Sep-2009 Douglas Gregor <dgregor@apple.com> When overload resolution fails for an overloaded operator, show the
overload candidates (but not the built-in ones). We still rely on the
underlying built-in semantic analysis to produce the initial
diagnostic, then print the candidates following that diagnostic.

One side advantage of this approach is that we can perform more validation
of C++'s operator overloading with built-in candidates vs. the
semantic analysis for those built-in operators: when there are no
viable candidates, we know to expect an error from the built-in
operator handling code. Otherwise, we are not modeling the built-in
semantics properly within operator overloading. This is checked as:

assert(Result.isInvalid() &&
"C++ binary operator overloading is missing
candidates!");
if (Result.isInvalid())
PrintOverloadCandidates(CandidateSet, /*OnlyViable=*/false);

The assert() catches cases where we're wrong in a +Asserts build. The
"if" makes sure that, if this happens in a production clang
(-Asserts), we still build the proper built-in operator and continue
on our merry way. This is effectively what happened before this
change, but we've added the assert() to catch more flies.

9c6a0e92dbf89897eae6106b24bfd017f269bfd0 22-Sep-2009 Douglas Gregor <dgregor@apple.com> Implement code completion within a function call, triggered after the
opening parentheses and after each comma. We gather the set of visible
overloaded functions, perform "partial" overloading based on the set
of arguments that we have thus far, and return the still-viable
results sorted by the likelihood that they will be the best candidate.

Most of the changes in this patch are a refactoring of the overloading
routines for a function call, since we needed to separate out the
notion of building an overload set (common to code-completion and
normal semantic analysis) and then what to do with that overload
set. As part of this change, I've pushed explicit template arguments
into a few more subroutines.

There is still much more work to do in this area. Function templates
won't be handled well (unless we happen to deduce all of the template
arguments before we hit the completion point), nor will overloaded
function-call operators or calls to member functions.

bd4c4aebe6035e7a7125470cc9f0f92511230ee3 27-Aug-2009 Douglas Gregor <dgregor@apple.com> When a member reference expression includes a qualifier on the member
name, e.g.,

x->Base::f()

retain the qualifier (and its source range information) in a new
subclass of MemberExpr called CXXQualifiedMemberExpr. Provide
construction, transformation, profiling, printing, etc., for this new
expression type.

When a virtual function is called via a qualified name, don't emit a
virtual call. Instead, call that function directly. Mike, could you
add a CodeGen test for this, too?

avoid emitting a warning on "someptr > 0". This is obviously questionable (they
could use != instead) but is reasonable, and the warning "ordered comparison
between pointer and integer" didn't make a ton of sense because 0 is a valid
null pointer constant.

Just silence the warning in this case, it is unlikely to indicate a bug.

This currently breaks test/SemaObjC/id-isa-ref.m and issues some spurious warnings when you attempt to assign a struct objc_class* value to a Class variable. The test case probably should fail as it's written, because without the definition of Class the compiler should not assume struct objc_class* is a valid receiver type, but it's left broken because it would be nice if we could get that passing too for the special case of isa.

Approved by snaroff.

A template name can refer to a set of overloaded function
templates. Model this in TemplateName, which can now refer to an
OverloadedFunctionDecl that contains function templates. This removes
an unspeakable hack in Sema::isTemplateName.

1a1a6e2bd4c5aefd7fd643cf25915f9623a02e59 16-Jul-2009 Ted Kremenek <kremenek@apple.com> Add member template 'Type::getAs<T>', which converts a Type* to a respective T*.
This method is intended to eventually replace the individual
Type::getAsXXXType<> methods.

The motivation behind this change is twofold:

1) Reduce redundant implementations of Type::getAsXXXType() methods. Most of
them are basically copy-and-paste.

2) By centralizing the implementation of the getAs<Type> logic we can more
smoothly move over to Doug Gregor's proposed canonical type smart pointer
scheme.

Along with this patch:

a) Removed 'Type::getAsPointerType()'; now clients use getAs<PointerType>.
b) Removed 'Type::getAsBlockPointerTypE()'; now clients use getAs<BlockPointerType>.

This removes the static data/methods on ObjCObjectPointerType while preserving the nice API (no need to fiddle with ASTContext:-).

This patch also adds Type::isObjCBuiltinType().

This should be the last fairly large patch related to recrafting the ObjC type system. The follow-on patches should be fairly small.

14108da7f7fc059772711e4ffee1322a27b152a7 11-Jul-2009 Steve Naroff <snaroff@apple.com> This patch includes a conceptually simple, but very intrusive/pervasive change.

The idea is to segregate Objective-C "object" pointers from general C pointers (utilizing the recently added ObjCObjectPointerType). The fun starts in Sema::GetTypeForDeclarator(), where "SomeInterface *" is now represented by a single AST node (rather than a PointerType whose Pointee is an ObjCInterfaceType). Since a significant amount of code assumed ObjC object pointers where based on C pointers/structs, this patch is very tedious. It should also explain why it is hard to accomplish this in smaller, self-contained patches.

This patch does most of the "heavy lifting" related to moving from PointerType->ObjCObjectPointerType. It doesn't include all potential "cleanups". The good news is additional cleanups can be done later (some are noted in the code). This patch is so large that I didn't want to include any changes that are purely aesthetic.

By making the ObjC types truly built-in, they are much easier to work with (and require fewer "hacks"). For example, there is no need for ASTContext::isObjCIdStructType() or ASTContext::isObjCClassStructType()! We believe this change (and the follow-up cleanups) will pay dividends over time.

Given the amount of code change, I do expect some fallout from this change (though it does pass all of the clang tests). If you notice any problems, please let us know asap! Thanks.

This was necessary to simplify some other changes I'm making (wrt ObjC type cleanups).

The idea is to separate the constraint checks for block pointers, ObjC pointers, and C pointers (the previous code combined them into one clause).

Note: This routine will be further simplified when I integrate the ObjC type cleanups (forthcoming).

b33fe2ff12676bff9db595fdf77e29014d7ba397 30-Jun-2009 Douglas Gregor <dgregor@apple.com> When recursively instantiating function templates, keep track of the
instantiation stack so that we provide a full instantiation
backtrace. Previously, we performed all of the instantiations implied
by the recursion, but each looked like a "top-level" instantiation.

The included test case tests the previous fix for the instantiation of
DeclRefExprs. Note that the "instantiated from" diagnostics still
don't tell us which template arguments we're instantiating with.

A test case for this change will come in with a large commit, which
illustrates what I was actually trying to work on.

1637be727f2a0434c1ed7aa385ea1c18328b0ccd 26-Jun-2009 Douglas Gregor <dgregor@apple.com> Implicit instantiation for function template specializations.

For a FunctionDecl that has been instantiated due to template argument
deduction, we now store the primary template from which it was
instantiated and the deduced template arguments. From this
information, we can instantiate the body of the function template.

e53060fa78ad7e98352049f72787bdb7543e2a48 26-Jun-2009 Douglas Gregor <dgregor@apple.com> Improved semantic analysis and AST respresentation for function
templates.

For example, this now type-checks (but does not instantiate the body
of deref<int>):

template<typename T> T& deref(T* t) { return *t; }

void test(int *ip) {
int &ir = deref(ip);
}

Specific changes/additions:
* Template argument deduction from a call to a function template.
* Instantiation of a function template specializations (just the
declarations) from the template arguments deduced from a call.
* FunctionTemplateDecls are stored directly in declaration contexts
and found via name lookup (all forms), rather than finding the
FunctionDecl and then realizing it is a template. This is
responsible for most of the churn, since some of the core
declaration matching and lookup code assumes that all functions are
FunctionDecls.

ac7610dad6653bad02dd42de198ca358b6fb1f1d 22-Jun-2009 Douglas Gregor <dgregor@apple.com> Rework the way we track which declarations are "used" during
compilation, and (hopefully) introduce RAII objects for changing the
"potentially evaluated" state at all of the necessary places within
Sema and Parser. Other changes:

- Set the unevaluated/potentially-evaluated context appropriately
during template instantiation.
- We now recognize three different states while parsing or
instantiating expressions: unevaluated, potentially evaluated, and
potentially potentially evaluated (for C++'s typeid).
- When we're in a potentially potentially-evaluated context, queue
up MarkDeclarationReferenced calls in a stack. For C++ typeid
expressions that are potentially evaluated, we will play back
these MarkDeclarationReferenced calls when we exit the
corresponding potentially potentially-evaluated context.
- Non-type template arguments are now parsed as constant
expressions, so they are not potentially-evaluated.

1c0ca59416999129d0439c2661d137ef38e86209 22-May-2009 Douglas Gregor <dgregor@apple.com> Representation of and template instantiation for member
expressions. This change introduces another AST node,
CXXUnresolvedMemberExpr, that captures member references (x->m, x.m)
when the base of the expression (the "x") is type-dependent, and we
therefore cannot resolve the member reference yet.

Note that our parsing of member references for C++ is still quite
poor, e.g., we don't handle x->Base::m or x->operator int.

I eventually plan to assert in mergeTypes that we aren't in C++ mode

remaining callers for code in the regression tests are
Sema::WarnConflictingTypedMethods and CodeGenFunction::EmitFunctionProlog;
I'm not quite sure what the correct approach is for those callers.

VerifyIntegerConstantExpression instead of isIntegerConstantExpr.
This makes it ext-warn but tolerate things that fold to a constant
but that are not valid i-c-e's.

There must be a bug in the i-c-e computation though, because it
doesn't catch this case even with pedantic.

This also switches the later code to use EvaluateAsInt which is
simpler and handles everything that evaluate does.

5153ee66d6d4fb37b02f85df38e48dc8b46660df 25-Apr-2009 Chris Lattner <sabre@nondot.org> Change SemaType's "GetTypeForDeclarator" and "ConvertDeclSpecToType" to
always return a non-null QualType + error bit. This fixes a bunch of
cases that didn't check for null result (and could thus crash) and eliminates
some crappy code scattered throughout sema.

This also improves the diagnostics in the recursive struct case to eliminate
a bogus second error. It also cleans up the case added to function.c by forming
a proper function type even though the declarator is erroneous, allowing the
parameter to be added to the function. Before:

t.c:2:1: error: unknown type name 'unknown_type'
unknown_type f(void*P)
^
t.c:4:3: error: use of undeclared identifier 'P'
P+1;
^

After:
t.c:2:1: error: unknown type name 'unknown_type'
unknown_type f(void*P)
^

Several changes here:
1. We change Type::isIncompleteType to realize that forward declared
interfaces are incomplete. This eliminate special case code for this
from the sizeof path, and starts us rejecting P[4] when P is a pointer
to an incomplete interface.
2. Explicitly reject P[4] when P points to an interface in non-fragile ABI
mode.
3. Switch the sizeof(interface) diagnostic back to an error instead of a
warning in non-fragile abi mode.

As part of this, make ObjCImplDecl inherit from NamedDecl (since

b28317a8e5e0e2953d1e5406d753d6c3c7f1e7d2 28-Mar-2009 Chris Lattner <sabre@nondot.org> Introduce a new OpaquePtr<N> struct type, which is a simple POD wrapper for a
pointer. Its purpose in life is to be a glorified void*, but which does not
implicitly convert to void* or other OpaquePtr's with a different UID.

Introduce Action::DeclPtrTy which is a typedef for OpaquePtr<0>. Change the
entire parser/sema interface to use DeclPtrTy instead of DeclTy*. This
makes the C++ compiler enforce that these aren't convertible to other opaque
types.

We should also convert ExprTy, StmtTy, TypeTy, AttrTy, BaseTy, etc,
but I don't plan to do that in the short term.

The one outstanding known problem with this patch is that we lose the
bitmangling optimization where ActionResult<DeclPtrTy> doesn't know how to
bitmangle the success bit into the low bit of DeclPtrTy. I will rectify
this with a subsequent patch.

5953d8b37f92f0cf548941f617c9b0a7703df33b 19-Mar-2009 Douglas Gregor <dgregor@apple.com> Introduce a new expression type, UnresolvedDeclRefExpr, that describes
dependent qualified-ids such as

Fibonacci<N - 1>::value

where N is a template parameter. These references are "unresolved"
because the name is dependent and, therefore, cannot be resolved to a
declaration node (as we would do for a DeclRefExpr or
QualifiedDeclRefExpr). UnresolvedDeclRefExprs instantiate to
DeclRefExprs, QualifiedDeclRefExprs, etc.

Also, be a bit more careful about keeping only a single set of
specializations for a class template, and instantiating from the
definition of that template rather than a previous declaration. In
general, we need a better solution for this for all TagDecls, because
it's too easy to accidentally look at a declaration that isn't the
definition.

We can now process a simple Fibonacci computation described as a
template metaprogram.

e4e5b054b4917f0ee493bb2fda5b1ec749bfb9a1 19-Mar-2009 Douglas Gregor <dgregor@apple.com> Introduce a representation for types that we referred to via a
qualified name, e.g.,

foo::x

so that we retain the nested-name-specifier as written in the source
code and can reproduce that qualified name when printing the types
back (e.g., in diagnostics). This is PR3493, which won't be complete
until finished the other tasks mentioned near the end of this commit.

The parser's representation of nested-name-specifiers, CXXScopeSpec,
is now a bit fatter, because it needs to contain the scopes that
precede each '::' and keep track of whether the global scoping
operator '::' was at the beginning. For example, we need to keep track
of the leading '::', 'foo', and 'bar' in

::foo::bar::x

The Action's CXXScopeTy * is no longer a DeclContext *. It's now the
opaque version of the new NestedNameSpecifier, which contains a single
component of a nested-name-specifier (either a DeclContext * or a Type
*, bitmangled).

The new sugar type QualifiedNameType composes a sequence of
NestedNameSpecifiers with a representation of the type we're actually
referring to. At present, we only build QualifiedNameType nodes within
Sema::getTypeName. This will be extended to other type-constructing
actions (e.g., ActOnClassTemplateId).

Also on the way: QualifiedDeclRefExprs will also store a sequence of
NestedNameSpecifiers, so that we can print out the property
nested-name-specifier. I expect to also use this for handling
dependent names like Fibonacci<I - 1>::value.

Type pointer. This allows our nested-name-specifiers to retain more

nested-name-specifiers that don't map to any DeclContext.

063daf6e196c51f162e0485478355d8e280eef5c 13-Mar-2009 Douglas Gregor <dgregor@apple.com> Refactor the way we handle operator overloading and template
instantiation for binary operators. This change moves most of the
operator-overloading code from the parser action ActOnBinOp to a new,
parser-independent semantic checking routine CreateOverloadedBinOp.

Of particular importance is the fact that CreateOverloadedBinOp does
*not* perform any name lookup based on the current parsing context (it
doesn't take a Scope*), since it has to be usable during template
instantiation, when there is no scope information. Rather, it takes a
pre-computed set of functions that are visible from the context or via
argument-dependent lookup, and adds to that set any member operators
and built-in operator candidates. The set of functions is computed in
the parser action ActOnBinOp based on the current context (both
operator name lookup and argument-dependent lookup). Within a
template, the set computed by ActOnBinOp is saved within the
type-dependent AST node and is augmented with the results of
argument-dependent name lookup at instantiation time (see
TemplateExprInstantiator::VisitCXXOperatorCallExpr).

Sadly, we can't fully test this yet. I'll follow up with template
instantiation for sizeof so that the real fun can begin.

This solution is much simpler (and doesn't add any per-scope overhead, which concerned Chris).

The only downside is the LabelMap is now declared in two places (Sema and BlockSemaInfo). My original fix tried to unify the LabelMap in "Scope" (which would support nested functions in general). In any event, this fixes the bug given the current language definition. If/when we decide to support GCC style nested functions, this will need to be tweaked.

72564e73277e29f6db3305d1f27ba408abb7ed88 27-Feb-2009 Douglas Gregor <dgregor@apple.com> Create a new TypeNodes.def file that enumerates all of the types,
giving them rough classifications (normal types, never-canonical
types, always-dependent types, abstract type representations) and
making it far easier to make sure that we've hit all of the cases when
decoding types.

Switched some switch() statements on the type class over to using this
mechanism, and filtering out those things we don't care about. For
example, CodeGen should never see always-dependent or non-canonical
types, while debug info generation should never see always-dependent
types. More switch() statements on the type class need to be moved
over to using this approach, so that we'll get warnings when we add a
new type then fail to account for it somewhere in the compiler.

As part of this, some types have been renamed:

TypeOfExpr -> TypeOfExprType
FunctionTypeProto -> FunctionProtoType
FunctionTypeNoProto -> FunctionNoProtoType

There shouldn't be any functionality change...

4b2d3f7bcc4df31157df443af1b80bcaa9b58bba 26-Feb-2009 Douglas Gregor <dgregor@apple.com> Introduce code modification hints into the diagnostics system. When we
know how to recover from an error, we can attach a hint to the
diagnostic that states how to modify the code, which can be one of:

- Insert some new code (a text string) at a particular source
location
- Remove the code within a given range
- Replace the code within a given range with some new code (a text
string)

Right now, we use these hints to annotate diagnostic information. For
example, if one uses the '>>' in a template argument in C++98, as in
this code:

template<int I> class B { };
B<1000 >> 2> *b1;

we'll warn that the behavior will change in C++0x. The fix is to
insert parenthese, so we use code insertion annotations to illustrate
where the parentheses go:

test.cpp:10:10: warning: use of right-shift operator ('>>') in template
argument will require parentheses in C++0x
B<1000 >> 2> *b1;
^
( )


Use of these annotations is partially implemented for HTML
diagnostics, but it's not (yet) producing valid HTML, which may be
related to PR2386, so it has been #if 0'd out.

In this future, we could consider hooking this mechanism up to the
rewriter to actually try to fix these problems during compilation (or,
after a compilation whose only errors have fixes). For now, however, I
suggest that we use these code modification hints whenever we can, so
that we get better diagnostics now and will have better coverage when
we find better ways to use this information.

This also fixes PR3410 by placing the complaint about missing tokens
just after the previous token (rather than at the location of the next
token).

(as GCC does), except when we've performed overload resolution and
found an unavailable function: in this case, we actually error.

Merge the checking of unavailable functions with the checking for
deprecated functions. This unifies a bit of code, and makes sure that
we're checking for unavailable functions in the right places. Also,
this check can cause an error. We may, eventually, want an option to
make "unavailable" warnings into errors.

Implement much of the logic needed for C++0x deleted functions, which
are effectively the same as "unavailable" functions (but always cause

into actual attributes on the function declaration.

Use the "printf" format attribute on function declarations to
determine whether we should do format string checking, rather than
looking at an ad hoc list of builtins and "known" function names.

Be a bit more careful about when we consider a function a "builtin" in
C++.

3e41d60eb627dc227c770f1c1c87d06909cf05fd 14-Feb-2009 Douglas Gregor <dgregor@apple.com> Implicitly declare certain C library functions (malloc, strcpy, memmove,
etc.) when we perform name lookup on them. This ensures that we
produce the correct signature for these functions, which has two
practical impacts:

1) When we're supporting the "implicit function declaration" feature
of C99, these functions will be implicitly declared with the right
signature rather than as a function returning "int" with no
prototype. See PR3541 for the reason why this is important (hint:
GCC always predeclares these functions).

2) If users attempt to redeclare one of these library functions with
an incompatible signature, we produce a hard error.

This patch does a little bit of work to give reasonable error
messages. For example, when we hit case #1 we complain that we're
implicitly declaring this function with a specific signature, and then
we give a note that asks the user to include the appropriate header
(e.g., "please include <stdlib.h> or explicitly declare 'malloc'"). In
case #2, we show the type of the implicit builtin that was incorrectly
declared, so the user can see the problem. We could do better here:
for example, when displaying this latter error message we say
something like:

'strcpy' was implicitly declared here with type 'char *(char *, char
const *)'

but we should really print out a fake code line showing the
declaration, like this:

'strcpy' was implicitly declared here as:

char *strcpy(char *, char const *)

This would also be good for printing built-in candidates with C++
operator overloading.

The set of C library functions supported by this patch includes all
functions from the C99 specification's <stdlib.h> and <string.h> that
(a) are predefined by GCC and (b) have signatures that could cause
codegen issues if they are treated as functions with no prototype
returning and int. Future work could extend this set of functions to
other C library functions that we know about.

f9201e0ff1779567150b70856753d9f2c6a91467 12-Feb-2009 Douglas Gregor <dgregor@apple.com> Initial implementation of function overloading in C.

This commit adds a new attribute, "overloadable", that enables C++
function overloading in C. The attribute can only be added to function
declarations, e.g.,

int *f(int) __attribute__((overloadable));

If the "overloadable" attribute exists on a function with a given
name, *all* functions with that name (and in that scope) must have the
"overloadable" attribute. Sets of overloaded functions with the
"overloadable" attribute then follow the normal C++ rules for
overloaded functions, e.g., overloads must have different
parameter-type-lists from each other.

When calling an overloaded function in C, we follow the same
overloading rules as C++, with three extensions to the set of standard
conversions:

- A value of a given struct or union type T can be converted to the
type T. This is just the identity conversion. (In C++, this would
go through a copy constructor).
- A value of pointer type T* can be converted to a value of type U*
if T and U are compatible types. This conversion has Conversion
rank (it's considered a pointer conversion in C).
- A value of type T can be converted to a value of type U if T and U
are compatible (and are not both pointer types). This conversion
has Conversion rank (it's considered to be a new kind of
conversion unique to C, a "compatible" conversion).

Known defects (and, therefore, next steps):
1) The standard-conversion handling does not understand conversions
involving _Complex or vector extensions, so it is likely to get
these wrong. We need to add these conversions.
2) All overloadable functions with the same name will have the same
linkage name, which means we'll get a collision in the linker (if
not sooner). We'll need to mangle the names of these functions.

- Made allocation of Stmt objects using vanilla new/delete a *compiler
error* by making this new/delete "protected" within class Stmt.
- Now the only way to allocate Stmt objects is by using the new
operator that takes ASTContext& as an argument. This ensures that
all Stmt nodes are allocated from the same (pool) allocator.
- Naturally, these two changes required that *all* creation sites for
AST nodes use new (ASTContext&). This is a large patch, but the
majority of the changes are just this mechanical adjustment.
- The above changes also mean that AST nodes can no longer be
deallocated using 'delete'. Instead, one most do
StmtObject->Destroy(ASTContext&) or do
ASTContextObject.Deallocate(StmtObject) (the latter not running the
'Destroy' method).

Along the way I also...
- Made CompoundStmt allocate its array of Stmt* using the allocator in
ASTContext (previously it used std::vector). There are a whole
bunch of other Stmt classes that need to be similarly changed to
ensure that all memory allocated for ASTs comes from the allocator
in ASTContext.
- Added a new smart pointer ExprOwningPtr to Sema.h. This replaces
the uses of llvm::OwningPtr within Sema, as llvm::OwningPtr used
'delete' to free memory instead of a Stmt's 'Destroy' method.

Big thanks to Doug Gregor for helping with the acrobatics of making
'new/delete' private and the new smart pointer ExprOwningPtr!

effectively the same thing but will work for both templates and
non-templates.

Additionally, we cope with all unqualified-ids, since ADL also applies

fa047648b2a5502d7eef117adb4777eb9a63baa6 04-Feb-2009 Douglas Gregor <dgregor@apple.com> Initial implementation of argument dependent lookup (a.k.a. ADL,
a.k.a. Koenig lookup) in C++. Most of the pieces are in place, but for
two:

- In an unqualified call g(x), even if the name does not refer to
anything in the current scope, we can still find functions named
"g" based on ADL. We don't yet have this ability.
- ADL will need updating for friend functions and templates.

4c921ae760cbdd9270c16d48417d7d527eb0ceb8 30-Jan-2009 Douglas Gregor <dgregor@apple.com> Eliminated LookupCriteria, whose creation was causing a bottleneck for
LookupName et al. Instead, use an enum and a bool to describe its
contents.

Optimized the C/Objective-C path through LookupName, eliminating any
unnecessarily C++isms. Simplify IdentifierResolver::iterator, removing
some code and arguments that are no longer used.

Eliminated LookupDeclInScope/LookupDeclInContext, moving all callers
over to LookupName, LookupQualifiedName, or LookupParsedName, as
appropriate.

All together, I'm seeing a 0.2% speedup on Cocoa.h with PTH and
-disable-free. Plus, we're down to three name-lookup routines.

4c67834407ca6ab344dcf44fc599ad4938cfa96d 28-Jan-2009 Douglas Gregor <dgregor@apple.com> Code generation support for C99 designated initializers.

The approach I've taken in this patch is relatively straightforward,
although the code itself is non-trivial. Essentially, as we process
an initializer list we build up a fully-explicit representation of the
initializer list, where each of the subobject initializations occurs
in order. Designators serve to "fill in" subobject initializations in
a non-linear way. The fully-explicit representation makes initializer
lists (both with and without designators) easy to grok for codegen and
later semantic analyses. We keep the syntactic form of the initializer
list linked into the AST for those clients interested in exactly what
the user wrote.

Known limitations:
- Designating a member of a union that isn't the first member may
result in bogus initialization (we warn about this)
- GNU array-range designators are not supported (we warn about this)

eb11cd078ba8682bbb9b082f8f6ead8be5c98581 14-Jan-2009 Douglas Gregor <dgregor@apple.com> Refactor name lookup.

This change refactors and cleans up our handling of name lookup with
LookupDecl. There are several aspects to this refactoring:

- The criteria for name lookup is now encapsulated into the class
LookupCriteria, which replaces the hideous set of boolean values
that LookupDecl currently has.

- The results of name lookup are returned in a new class
LookupResult, which can lazily build OverloadedFunctionDecls for
overloaded function sets (and, eventually, eliminate the need to
allocate member for OverloadedFunctionDecls) and contains a
placeholder for handling ambiguous name lookup (for C++).

- The primary entry points for name lookup are now LookupName (for
unqualified name lookup) and LookupQualifiedName (for qualified
name lookup). There is also a convenience function
LookupParsedName that handles qualified/unqualified name lookup
when given a scope specifier. Together, these routines are meant
to gradually replace the kludgy LookupDecl, but this won't happen
until after we have base class lookup (which forces us to cope
with ambiguities).

- Documented the heck out of name lookup. Experimenting a little
with using Doxygen's member groups to make some sense of the Sema
class. Feedback welcome!

- Fixes some lingering issues with name lookup for
nested-name-specifiers, which now goes through
LookupName/LookupQualifiedName.

These changes cause -fsyntax-only to not page in any sources from

bcbffc46f1ad3796c4582fa1e3a9113b5aa26061 07-Jan-2009 Douglas Gregor <dgregor@apple.com> Initial implementation of anonymous unions (and, as a GNU extension,
structures and classes) in C++. Covers name lookup and the synthesis
and member access for the unnamed objects/fields associated with
anonymous unions.

Some C++ semantic checks are still missing (anonymous unions can't
have function members, static data members, etc.), and there is no
support for anonymous structs or unions in C.

1a49af9681c350fef58e677f85ccb9a77e8e9d0a 06-Jan-2009 Douglas Gregor <dgregor@apple.com> Add QualifiedDeclRefExpr, which retains additional source-location
information for declarations that were referenced via a qualified-id,
e.g., N::C::value. We keep track of the location of the start of the
nested-name-specifier. Note that the difference between
QualifiedDeclRefExpr and DeclRefExpr does have an effect on the
semantics of function calls in two ways:
1) The use of a qualified-id instead of an unqualified-id suppresses
argument-dependent lookup
2) If the name refers to a virtual function, the qualified-id
version will call the function determined statically while the
unqualified-id version will call the function determined dynamically
(by looking up the appropriate function in the vtable).

Neither of these features is implemented yet, but we do print out
qualified names for QualifiedDeclRefExprs as part of the AST printing.

61366e9cd41a6dbde4e66416dac21269c8ac1d94 24-Dec-2008 Douglas Gregor <dgregor@apple.com> Correct the order in which we cope with end-of-class-definition
semantics and improve our handling of default arguments. Specifically,
we follow this order:

- As soon as the see the '}' in the class definition, the class is
complete and we add any implicit declarations (default constructor,
copy constructor, etc.) to the class.
- If there are any default function arguments, parse them
- If there were any inline member function definitions, parse them

As part of this change, we now keep track of the the fact that we've
seen unparsed default function arguments within the AST. See the new
ParmVarDecl::hasUnparsedDefaultArg member. This allows us to properly
cope with calls inside default function arguments to other functions
where we're making use of the default arguments.

Made some C++ error messages regarding failed initializations more
specific.

3fc749d899dfc194162128c1a88933148a39b68d 23-Dec-2008 Douglas Gregor <dgregor@apple.com> Don't explicitly represent OverloadedFunctionDecls within
DeclContext. Instead, just keep the list of currently-active
declarations and only build the OverloadedFunctionDecl when we
absolutely need it.

This is a half-step toward eliminating the need to explicitly build
OverloadedFunctionDecls that store sets of overloaded
functions. This was suggested by Argiris a while back, and it's a good
thing for several reasons: first, it eliminates the messy logic that
currently tries to keep the OverloadedFunctionDecl in sync with the
declarations that are being added. Second, it will (eventually)
eliminate the need to allocate memory for overload sets, which could
help performance. Finally, it helps set us up for when name lookup can
return multiple (possibly ambiguous) results, as can happen with
lookup of class members in C++.

Next steps: make the IdentifierResolver store overloads as separate
entries in its list rather than replacing them with an
OverloadedFunctionDecl now, then see how far we can go toward
eliminating OverloadedFunctionDecl entirely.

- Overloading has to cope with having both static and non-static
member functions in the overload set.
- The call may or may not have an implicit object argument,
depending on the syntax (x.f() vs. f()) and the context (static
vs. non-static member function).
- We now generate MemberExprs for implicit member access expression.
- We now cope with mutable whenever we're building MemberExprs.

44b4321feab46299d3f5cfd404680884752a0fcf 11-Dec-2008 Douglas Gregor <dgregor@apple.com> Unifies the name-lookup mechanisms used in various parts of the AST
and separates lexical name lookup from qualified name lookup. In
particular:
* Make DeclContext the central data structure for storing and
looking up declarations within existing declarations, e.g., members
of structs/unions/classes, enumerators in C++0x enums, members of
C++ namespaces, and (later) members of Objective-C
interfaces/implementations. DeclContext uses a lazily-constructed
data structure optimized for fast lookup (array for small contexts,
hash table for larger contexts).

* Implement C++ qualified name lookup in terms of lookup into
DeclContext.

* Implement C++ unqualified name lookup in terms of
qualified+unqualified name lookup (since unqualified lookup is not
purely lexical in C++!)

* Limit the use of the chains of declarations stored in
IdentifierInfo to those names declared lexically.

* Eliminate CXXFieldDecl, collapsing its behavior into
FieldDecl. (FieldDecl is now a ScopedDecl).

* Make RecordDecl into a DeclContext and eliminates its
Members/NumMembers fields (since one can just iterate through the
DeclContext to get the fields).

Note that when we see "g(", we build a CXXDependentNameExpr. However,
if none of the call arguments are type-dependent, we will force the
resolution of the name "g" and replace the CXXDependentNameExpr with
its result.

GCC actually produces a nice error message when you make this
mistake, and even offers to compile your code with -fpermissive. I'll
do the former next, but I don't plan to do the latter.

bunch of minor inconsistencies in the diagnostics emitted by clang
and adds a bunch of FIXME's to DiagnosticKinds.def.

uses of getName() with uses of getDeclName(). This upgrades a bunch of
diags to take DeclNames instead of std::strings.

This also tweaks a couple of diagnostics to be cleaner and changes
CheckInitializerTypes/PerformInitializationByConstructor to pass
around DeclarationNames instead of std::strings.

08631c5fa053867146b5ee8be658c229f6bf127c 23-Nov-2008 Chris Lattner <sabre@nondot.org> Convert IdentifierInfo's to be printed the same as DeclarationNames
with implicit quotes around them. This has a bunch of follow-on
effects and requires tweaking to a whole lot of code. This causes
a regression in two tests (xfailed) by causing it to emit things like:

Line 10: duplicate interface declaration for category 'MyClass1' ('Category1')

instead of:

Line 10: duplicate interface declaration for category 'MyClass1(Category1)'

I will fix this in a follow-up commit.

As part of this, I had to start switching stuff to use ->getDeclName() instead
of Decl::getName() for consistency. This is good, but I was planning to do this
as an independent patch. There will be several follow-on patches
to clean up some of the mess, but this patch is already too big.

Fix a typo in the promotion of enumeration types that was causing some
integral promotions to look like integral conversions (leading to
extra ambiguities in overload resolution).

Check for "acceptable" overloaded operators based on the types of the
arguments. This is a somewhat odd check that is specified by the
standard, but I can't see why it actually matters: the overload
candidates it suppresses don't seem like they would ever be picked as
the best candidates.

96176b3575823ea996c6140380dd17d9240c9766 19-Nov-2008 Douglas Gregor <dgregor@apple.com> Partial expansion of C++ operator overloading (for binary operators)
to support operators defined as member functions, e.g.,

struct X {
bool operator==(X&);
};

Overloading with non-member operators is supported, and the special
rules for the implicit object parameter (e.g., the ability for a
non-const *this to bind to an rvalue) are implemented.

This change also refactors and generalizes the code for adding
overload candidates for overloaded operator calls (C++ [over.match.expr]),
both to match the rules more exactly (name lookup of non-member
operators actually ignores member operators) and to make this routine
more reusable for the other overloaded operators.

Testing for the initialization of the implicit object parameter is
very light. More tests will come when we get support for calling
member functions directly (e.g., o.m(a1, a2)).

Note that we still have the three parser entry points for identifiers,

Thing (TM), and there will be more entrypoints coming (e.g., for C++

operator+, directly, using the same mechanism as all other special
names.

Removed the "special" identifiers for the overloaded operators from
the identifier table and IdentifierInfo data structure. IdentifierInfo
is back to representing only real identifiers.

Added a new Action, ActOnOperatorFunctionIdExpr, that builds an
expression from an parsed operator-function-id (e.g., "operator
+"). ActOnIdentifierExpr used to do this job, but
operator-function-ids are no longer represented by IdentifierInfo's.

Extended Declarator to store overloaded operator names.
Sema::GetNameForDeclarator now knows how to turn the operator
name into a DeclarationName for the overloaded operator.

Except for (perhaps) consolidating the functionality of
ActOnIdentifier, ActOnOperatorFunctionIdExpr, and
ActOnConversionFunctionExpr into a common routine that builds an
appropriate DeclRefExpr by looking up a DeclarationName, all of the
work on normalizing declaration names should be complete with this
commit.

b4609806e9232593ece09ce08b630836e825865c 14-Nov-2008 Douglas Gregor <dgregor@apple.com> Add a new expression node, CXXOperatorCallExpr, which expresses a
function call created in response to the use of operator syntax that
resolves to an overloaded operator in C++, e.g., "str1 +
str2" that resolves to std::operator+(str1, str2)". We now build a
CXXOperatorCallExpr in C++ when we pick an overloaded operator. (But
only for binary operators, where we actually implement overloading)

I decided *not* to refactor the current CallExpr to make it abstract
(with FunctionCallExpr and CXXOperatorCallExpr as derived
classes). Doing so would allow us to make CXXOperatorCallExpr a little
bit smaller, at the cost of making the argument and callee accessors
virtual. We won't know if this is going to be a win until we can parse
lots of C++ code to determine how much memory we'll save by making
this change vs. the performance penalty due to the extra virtual
calls.

eb8f3063257a392f15aea48d42fb73ec51afc548 12-Nov-2008 Douglas Gregor <dgregor@apple.com> Implement support for operator overloading using candidate operator
functions for built-in operators, e.g., the builtin

bool operator==(int const*, int const*)

can be used for the expression "x1 == x2" given:

struct X {
operator int const*();
} x1, x2;

The scheme for handling these built-in operators is relatively simple:
for each candidate required by the standard, create a special kind of
candidate function for the built-in. If overload resolution picks the
built-in operator, we perform the appropriate conversions on the
arguments and then let the normal built-in operator take care of it.

There may be some optimization opportunity left: if we can reduce the
number of built-in operator overloads we generate, overload resolution
for these cases will go faster. However, one must be careful when
doing this: GCC generates too few operator overloads in our little
test program, and fails to compile it because none of the overloads it
generates match.

Note that we only support operator overload for non-member binary
operators at the moment. The other operators will follow.

As part of this change, ImplicitCastExpr can now be an lvalue.

eaebc75ef6ff21fbc9f25ab4175cba465e4e0e43 07-Nov-2008 Douglas Gregor <dgregor@apple.com> Initial, rudimentary implementation of operator overloading for binary
operators. For example, one can now write "x + y" where x or y is a
class or enumeration type, and Clang will perform overload resolution
for "+" based on the overloaded operators it finds.

The other kinds of overloadable operators in C++ will follow this same
approach.

Three major issues remain:
1) We don't find member operators
2) Since we don't have user-defined conversion operators, we can't
call any of the built-in overloaded operators in C++ [over.built].
3) Once we've done the semantic checks, we drop the overloaded
operator on the floor; it doesn't get into the AST at all.

15da57e66cade0c2cab752f925e838b22daadafc 29-Oct-2008 Douglas Gregor <dgregor@apple.com> Tweak Sema::CheckReferenceInit so that it (optionally) computes an
ImplicitConversionSequence and, when doing so, following the specific
rules of [over.best.ics].

The computation of the implicit conversion sequences implements C++
[over.ics.ref], but we do not (yet) have ranking for implicit
conversion sequences that use reference binding.

27c8dc06f65d7abcf6a7e7f64a7960c9a150ca01 29-Oct-2008 Douglas Gregor <dgregor@apple.com> Implement initialization of a reference (C++ [dcl.init.ref]) as part
of copy initialization. Other pieces of the puzzle:

- Try/Perform-ImplicitConversion now handles implicit conversions
that don't involve references.
- Try/Perform-CopyInitialization uses
CheckSingleAssignmentConstraints for C. PerformCopyInitialization
is now used for all argument passing and returning values from a
function.
- Diagnose errors with declaring references and const values without
an initializer. (Uses a new Action callback, ActOnUninitializedDecl).

We do not yet have implicit conversion sequences for reference
binding, which means that we don't have any overloading support for
reference parameters yet.

- Do not allow expressions to ever have reference type
- Extend Expr::isLvalue to handle more cases where having written a

- Make GRExprEngine::VisitCall treat the call arguments as lvalues when
they are being bound to a reference parameter.

49badde06e066d058d6c7fcf4e628a72999b65a9 27-Oct-2008 Douglas Gregor <dgregor@apple.com> Refactor the expression class hierarchy for casts. Most importantly:
- CastExpr is the root of all casts
- ImplicitCastExpr is (still) used for all explicit casts
- ExplicitCastExpr is now the root of all *explicit* casts
- ExplicitCCastExpr (new name needed!?) is a C-style cast in C or C++
- CXXFunctionalCastExpr inherits from ExplicitCastExpr
- CXXNamedCastExpr inherits from ExplicitCastExpr and is the root of all
of the C++ named cast expression types (static_cast, dynamic_cast, etc.)
- Added classes CXXStaticCastExpr, CXXDynamicCastExpr,
CXXReinterpretCastExpr, and CXXConstCastExpr to

Also, fixed returned-stack-addr.cpp, which broke once when we fixed
reinterpret_cast to diagnose double->int* conversions and again when
we eliminated implicit conversions to reference types. The fix is in
both testcase and SemaChecking.cpp.

Most of this patch is simply support for the renaming. There's very
little actual change in semantics.

98cd599ee8a9b259ed7388ee2921a20d97658864 22-Oct-2008 Douglas Gregor <dgregor@apple.com> Initial step toward supporting qualification conversions (C++ 4.4).

Changes:
- Sema::IsQualificationConversion determines whether we have a qualification
conversion.
- Sema::CheckSingleAssignment constraints now follows the C++ rules in C++,
performing an implicit conversion from the right-hand side to the type of
the left-hand side rather than checking based on the C notion of
"compatibility". We now rely on the implicit-conversion code to
determine whether the conversion can happen or
not. Sema::TryCopyInitialization has an ugly reference-related
hack to cope with the initialization of references, for now.
- When building DeclRefExprs, strip away the reference type, since
there are no expressions whose type is a reference. We'll need to
do this throughout Sema.
- Expr::isLvalue now permits functions to be lvalues in C++ (but not
in C).

5e155f0c9bd5916d47a7d99dd8d5b26bdb44d835 12-Sep-2008 Daniel Dunbar <daniel@zuster.org> Iterate on sema for :? in Objective-C:
- Follow C99 behavior of using other operand type when one of
operands is a null pointer constant.
- Fix overenthusiastic devolving of any Objective-C types to id:
o If either operand has an Objective-C object type then:
- If both operands are interfaces and either operand can be
assigned to the other, use that type as the composite type.
- Otherwise, if either type is id, use id as the composite type.
- Otherwise, warn about incompatible types and use id as the
composite type.
- Return handling of qualified idea to separate test following
general pointer type checking.
o Upgraded from old code to allow devolving to id (without warning,
which matches GCC).
- <rdar://problem/6212771>

Add test case for issues fixed above, XFAIL though because it exposed
a new issue in property handling.

- Sema::ActOnBlockStart(), ActOnBlockError(), ActOnBlockStmtExpr(), ActOnBlockExprExpr(), ActOnBlockReturnStmt().

Next steps...

- hack Sema::ActOnIdentifierExpr() to deal with block decl refs.
- add attribute handler for byref decls.
- add test cases.

- Change Obj-C runtime message API, drop the ObjCMessageExpr arg in
favor of just result type and selector. Necessary so it can be
reused in situations where we don't want to cons up an
ObjCMessageExpr.
- Update aggregate binary assignment to know about special property
ref lvalues.
- Add CodeGenFunction::EmitCallArg overload which takes an already
emitted rvalue.

Add CodeGenFunction::StoreComplexIntoAddr.

Disabled logic in Sema for parsing Objective-C dot-syntax that
accesses methods. This code does not search in the correct order and
the AST node has no way of properly representing its results.

Updated StmtDumper to print a bit more information about
ObjCPropertyRefExprs.

a56f7460baf475151e03b1249a1343349328e39c 26-Aug-2008 Daniel Dunbar <daniel@zuster.org> In incompatible pointer-typed ?: expressions, add implicit conversion
of RHSs to id type instead of void* if either has Objective-C object
type.
- This ensures the result can still be used in normal places an
object can be used, like a message send.

Add implicit conversions for ?: applied to qualified id types to
ensure that the RHSs are compatible.
- This prevents a codegen crash (creating invalid PHI nodes).
- Again, this relates to the fact that qualified id types have no
canonical types.
- Note that the implicit type casted to is incorrect, however this
doesn't currently cause problems because of the flexibility of the
id type.

Test cases for above.

testing compatibility. This is necessary for some constructs, like merging
redeclarations.

Also, there are some ObjC changes to make sure that
typesAreCompatible(a,b) == typesAreCompatible(b,a). I don't have any
ObjC code beyond the testsuite, so please tell me if there are any cases
where this doesn't behave as expected.

"pseudo-keywords" should be collected into one place (this would
KnownFunctionIDs and Objective-C property IDs, for example).

so.

move getAsArrayType into ASTContext instead of being a method on type.
This is required because getAsArrayType(const AT), where AT is a typedef

Fixing this greatly simplifies getArrayDecayedType, which is a good sign.

problem with &&/||. 2) use canonical types for comparison instead
of raw types. 3) emit an ext-warn for a gnu extension.

Also simplify the code to make it less nested.

3) Change the TargetInfo.h get*Format methods to return their
fltSemantics byref instead of by pointer.
4) Change CodeGenFunction::EmitBuiltinExpr to allow builtins which
sometimes expand specially and othertimes fall back to libm.
5) Add support for __builtin_nan("") to codegen, cases that don't pass
in an empty string are currently lowered to libm calls.
6) Fix codegen of __builtin_infl.

the condidtional have compatible types, they are not necessarily the

left-hand expression; this isn't correct, but it's good enough for most
purposes.

While it is similar to the other compatibility predicates in ASTContext,
it is not used by them and is different.

In addition, greatly simplify ObjCQualifiedIdTypesAreCompatible and
fix some canonical type bugs. Also, simplify my Type::getAsObjC* methods.

b327ce02959d4e6224732e1c362e7f8e0688581f 02-Apr-2008 Steve Naroff <snaroff@apple.com> Two changes to Sema::LookupDecl() interface.
(1) Remove IdLoc (it's never used).
(2) Add a bool to enable/disable lazy builtin creaation (defaults to true).

This enables us to use LookupDecl() in Sema::isTypeName(), which is also part of this commit.

To make this work, I changed isTypeName() to be a non-const member function. I'm not happy with this, however I fiddled with making LookupDecl() and friends const and it got ugly pretty quickly. We can certainly add it back if/when someone has time to fiddle with it. For now, I thought this simplification was more important than retaining the const-ness.

d805bec0fbb98aa10abbb41bfdcb2e2fab1bac96 02-Apr-2008 Chris Lattner <sabre@nondot.org> Various parts of the standard require something to be an "incomplete or
object type". Add a predicate that checks exactly this, as it is equivalent
to checking ot see if the type is *not* a function type, which is faster
to check.

e6327747b72bb687c948270f702ff53c30f411a6 02-Apr-2008 Chris Lattner <sabre@nondot.org> Fix several bugs in array -> pointer decomposition.

First, we got several CVR propagation cases wrong, which Eli pointed
out in PR2039.

Second, we didn't propagate address space qualifiers correctly, leading
to incorrect lowering of code in CodeGen/address-space.c.

Third, we didn't uniformly propagate the specifier in the array to the
pointer ("int[restrict 4]" -> "int *restrict").

This adds an ASTContext::getArrayDecayedType member that handles the
non-trivial logic for this seemingly simple operation.

e8043c39176e7f253fbd92982b077eca6bf2fd59 02-Apr-2008 Steve Naroff <snaroff@apple.com> Fairly large "cleaup" related to changing ObjCCompatibleAliasDecl superclass (to inherit from NamedDecl, instead of ScopedDecl).

- Added a DenseMap to associate an IdentifierInfo with the ObjCCompatibleAliasDecl.
- Renamed LookupScopedDecl->LookupDecl and changed it's return type to Decl. Also added lookup for ObjCCompatibleAliasDecl's.
- Removed Sema::LookupInterfaceDecl(). Converted clients to used LookupDecl().
- Some minor indentation changes.

Will deal with ObjCInterfaceDecl and getObjCInterfaceDecl() in a separate commit...

Fix objc ivar lookup. Ivar lookup should occur between lookup
of method-local values and lookup of globals. Emulate this with
some logic in the handling of Sema::ActOnIdentifierExpr.

Two todo's left:
1) sema shouldn't turn a bare reference to an ivar into "self->ivar"
in the AST. This is a hack.
2) The new ScopedDecl::isDefinedOutsideFunctionOrMethod method does
not correctly handle typedefs and enum constants yet.

bda0b626e74513950405c27525af87e214e605e2 16-Mar-2008 Chris Lattner <sabre@nondot.org> Make a major restructuring of the clang tree: introduce a top-level
lib dir and move all the libraries into it. This follows the main
llvm tree, and allows the libraries to be built in parallel. The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in. This speeds
up parallel builds, particularly incremental ones.
