a7b879723d3989d85b9492fd8218e7d745367fe3 07-Aug-2013 Jordan Rose <jordan_rose@apple.com> Eliminate CXXConstructorDecl::IsImplicitlyDefined.

This field is just IsDefaulted && !IsDeleted; in all places it's used,
a simple check for isDefaulted() is superior anyway, and we were forgetting
to set it in a few cases.

Also eliminate CXXDestructorDecl::IsImplicitlyDefined, for the same reasons.

No intended functionality change.

1888b910a5512262228e785cc9caf90296c06a45 02-Aug-2013 Richard Smith <richard-llvm@metafoo.co.uk> When merging redeclaration chains across modules, if a declaration is visible
in one module but is only declared as a friend in another module, keep it
visible in the result of the merge.

This is incomplete on two axes:

1) Our handling of local extern declarations is basically broken (we put them
in the wrong decl context, and don't find them in redeclaration lookup, unless
they've previously been declared), and this results in them making friends
visible after a merge.

2) Eventually we'll need to mark that this has happened, and more carefully
check whether a declaration should be visible if it was only visible in some
of the modules in which it was declared. Fortunately it's rare for the
identifier namespace of a declaration to change along its redeclaration chain.

a99ecbcc4c431d52df0b01539035ab5281d54656 25-May-2013 Rafael Espindola <rafael.espindola@gmail.com> Fix linkage computation for derived types in inline functions.

John noticed that the fix for pr15930 (r181981) didn't handle indirect
uses of local types. For example, a pointer to local struct, or a
function that returns it.

One way to implement this would be to recursively look for local
types. This would look a lot like the linkage computation itself for
types.

To avoid code duplication and utilize the existing linkage cache, this
patch just makes the computation of "type with no linkage but
externally visible because it is from an inline function" part of the
linkage computation itself.

specialization with modules enabled. Just don't merge them at all for now;
we'll revisit this when support for template merging is added.

In passing, make Decl::dump() a little safer to use with PCH/modules, by making
it not deserialize any additional declarations. From a debugger you can call
decls_begin() or similar first if you want to dump all child decls.

a FieldDecl from it, and propagate both into the closure type and the
LambdaExpr.

You can't do much useful with them yet -- you can't use them within the body
of the lambda, because we don't have a representation for "the this of the
lambda, not the this of the enclosing context". We also don't have support or a
representation for a nested capture of an init-capture yet, which was intended
to work despite not being allowed by the current standard wording.

This patch renames getLinkage to getLinkageInternal. Only code that
needs to handle UniqueExternalLinkage specially should call this.

Linkage, as defined in the c++ standard, is provided by
getFormalLinkage. It maps UniqueExternalLinkage to ExternalLinkage.

Most places in the compiler actually want isExternallyVisible, which
handles UniqueExternalLinkage as internal.

This commit introduces a set of related changes to ensure that the
declaration that shows up in the identifier chain after deserializing
declarations with a given identifier is, in fact, the most recent
declaration. The primary change involves waiting until after we
deserialize and wire up redeclaration chains before updating the
identifier chains. There is a minor optimization in here to avoid
recursively deserializing names as part of looking to see whether
top-level declarations for a given name exist.

A related change that became suddenly more urgent is to property
record a merged declaration when an entity first declared in the
current translation unit is later deserialized from a module (that had
not been loaded at the time of the original declaration). Since we key
off the canonical declaration (which is parsed, not from an AST file)
for emitted redeclarations, we simply record this as a merged
declaration during AST writing and let the readers merge them.

Re-fixes <rdar://problem/13189985>, presumably for good this time.

name lookup has been performed in that context (this probably only happens in

1) Whenever we add names to a context, set a flag on it, and if we perform
lookup and discover that the context has had a lookup table built but has the
flag set, update all entries in the lookup table with additional names from
the external source.

2) When marking a DeclContext as having external visible decls, mark the
context in which lookup is performed, not the one we are adding. These won't
be the same if we're adding another copy of a pre-existing namespace.

d329724745b49f894b768d47275b7c2713106e89 17-Jan-2013 Douglas Gregor <dgregor@apple.com> Rework the traversal of Objective-C categories and extensions to
consider (sub)module visibility.

The bulk of this change replaces myriad hand-rolled loops over the
linked list of Objective-C categories/extensions attached to an
interface declaration with loops using one of the four new category
iterator kinds:

visible_categories_iterator: Iterates over all visible categories
and extensions, hiding any that have their "hidden" bit set. This is
by far the most commonly used iterator.

known_categories_iterator: Iterates over all categories and
extensions, ignoring the "hidden" bit. This tends to be used for
redeclaration-like traversals.

visible_extensions_iterator: Iterates over all visible extensions,
hiding any that have their "hidden" bit set.

known_extensions_iterator: Iterates over all extensions, whether
they are visible to normal name lookup or not.

The effect of this change is that any uses of the visible_ iterators
will respect module-import visibility. See the new tests for examples.

Note that the old accessors for categories and extensions are gone;
there are *Raw() forms for some of them, for those (few) areas of the
compiler that have to manipulate the linked list of categories
directly. This is generally discouraged.

Part two of <rdar://problem/10634711>.

This does limit these typedefs to being sequences, but no current usage
requires them to be contiguous (we could expand this to a more general
iterator pair range concept at some point).

Also, it'd be nice if SmallVector were constructible directly from an ArrayRef
but this is a bit tricky since ArrayRef depends on SmallVectorBaseImpl for the
inverse conversion. (& generalizing over all range-like things, while nice,
would require some nontrivial SFINAE I haven't thought about yet)

bc2a35d5ff492107dab5bdb7682f0da2f4a88861 08-Dec-2012 Richard Smith <richard-llvm@metafoo.co.uk> Finish implementing 'selected constructor' rules for triviality in C++11. In
the cases where we can't determine whether special members would be trivial
while building the class, we eagerly declare those special members. The impact
of this is bounded, since it does not trigger implicit declarations of special
members in classes which merely *use* those classes.

In order to determine whether we need to apply this rule, we also need to
eagerly declare move operations and destructors in cases where they might be
deleted. If a move operation were supposed to be deleted, it would instead
be suppressed, and we could need overload resolution to determine if we fall
back to a trivial copy operation. If a destructor were implicitly deleted,
it would cause the move constructor of any derived classes to be suppressed.

As discussed on cxx-abi-dev, C++11's selected constructor rules are also
retroactively applied as a defect resolution in C++03 mode, in order to
identify that class B has a non-trivial copy constructor (since it calls
A's constructor template, not A's copy constructor):

struct A { template<typename T> A(T &); };
struct B { mutable A a; };

reference instead of relying on computing it.

In general, if storage is no issue, it is preferable to deserialize info from
the PCH instead of trying to recompute it after the PCH was loaded.

The incentive to change this now was due to r155303 changing how friend template
classes in dependent contexts are handled; such classes can now be chained to
a previous template class but the computed InjectedClassNameType may be different
due to the extra template parameters from the dependent context.

The new handling requires more investigation but, in the meantime, writing out
InjectedClassNameType fixes PCH issue in rdar://12627738.

whether a default constructor is constexpr. This doesn't affect correctness,
since default constructor lookup is much simpler than selecting a constructor
for copying or moving.

We don't need a corresponding mechanism for defaulted copy or move constructors,
since they can't affect whether a type is a literal type. Conversely, checking
whether such functions are constexpr can require non-trivial effort, so we defer
such checks until the copy or move constructor is required.

Thus we now only compute whether a copy or move constructor is constexpr on
demand, and only compute whether a default constructor is constexpr in advance.
This is unfortunate, but seems like the best solution.

ac1303eca6cbe3e623fb5ec6fe7ec184ef4b0dfa 22-Feb-2012 Douglas Gregor <dgregor@apple.com> Generate an AST for the conversion from a lambda closure type to a
block pointer that returns a block literal which captures (by copy)
the lambda closure itself. Some aspects of the block literal are left
unspecified, namely the capture variable (which doesn't actually
exist) and the body (which will be filled in by IRgen because it can't
be written as an AST).

Because we're switching to this model, this patch also eliminates
tracking the copy-initialization expression for the block capture of
the conversion function, since that information is now embedded in the
synthesized block literal. -1 side tables FTW.

arguments. There are two aspects to this:

- Make sure that when marking the declarations referenced in a
default argument, we don't try to mark local variables, both because
it's a waste of time and because the semantics are wrong: we're not
in a place where we could capture these variables again even if it
did make sense.
- When a lambda expression occurs in a default argument of a
function template, make sure that the corresponding closure type is
considered dependent, so that it will get properly instantiated. The
second bit is a bit of a hack; to fix it properly, we may have to
rearchitect our handling of default arguments, parsing them only
after creating the function definition. However, I'd like to
separate that work from the lambdas work.

default arguments of function parameters. This simple-sounding task is
complicated greatly by two issues:

(1) Default arguments aren't actually a real context, so we need to
maintain extra state within lambda expressions to track when a
lambda was actually in a default argument.
(2) At the time that we parse a default argument, the FunctionDecl
doesn't exist yet, so lambda closure types end up in the enclosing
context. It's not clear that we ever want to change that, so instead
we introduce the notion of the "effective" context of a declaration
for the purposes of name mangling.

instead of having a special-purpose function.

- ActOnCXXDirectInitializer, which was mostly duplication of
AddInitializerToDecl (leading e.g. to PR10620, which Eli fixed a few days
ago), is dropped completely.
- MultiInitializer, which was an ugly hack I added, is dropped again.
- We now have the infrastructure in place to distinguish between
int x = {1};
int x({1});
int x{1};
-- VarDecl now has getInitStyle(), which indicates which of the above was used.
-- CXXConstructExpr now has a flag to indicate that it represents list-
initialization, although this is not yet used.
- InstantiateInitializer was renamed to SubstInitializer and simplified.
- ActOnParenOrParenListExpr has been replaced by ActOnParenListExpr, which
always produces a ParenListExpr. Placed that so far failed to convert that
back to a ParenExpr containing comma operators have been fixed. I'm pretty
sure I could have made a crashing test case before this.

The end result is a (I hope) considerably cleaner design of initializers.
More importantly, the fact that I can now distinguish between the various
initialization kinds means that I can get the tricky generalized initializer
test cases Johannes Schaub supplied to work. (This is not yet done.)

This commit passed self-host, with the resulting compiler passing the tests. I
hope it doesn't break more complicated code. It's a pretty big change, but one
that I feel is necessary.

- In cases involving mixing and matching of many categories across
many modules, the linked-list structure would not be consistent
across different modules, and categories would get lost.
- If a module is loaded after the class definition and its other
categories have already been loaded, we wouldn't see any categories
in the newly-loaded module.

approach works well even when deserializing declarations that didn't
know about the original definition, which can occur with modules.

A nice bonus from this definition-deserialization approach is that we
no longer need update records when a definition is added, because the
redeclaration chains ensure that the if any declaration is loaded, the
definition will also get loaded.

chains, again. The prior implementation was very linked-list oriented, and
the list-splicing logic was both fairly convoluted (when loading from
multiple modules) and failed to preserve a reasonable ordering for the
redeclaration chains.

This new implementation uses a simpler strategy, where we store the
ordered redeclaration chains in an array-like structure (indexed based
on the first declaration), and use that ordering to add individual
deserialized declarations to the end of the existing chain. That way,
the chain mimics the ordering from its modules, and a bug somewhere is
far less likely to result in a broken linked list.

b6b60c1521a2e65f60e93c5fd56c103cf027df63 05-Jan-2012 Douglas Gregor <dgregor@apple.com> When we deserialize a declaration from a module file, allocate extra
storage for the global declaration ID. Declarations that are parsed
(rather than deserialized) are unaffected, so the number of
declarations that pay this cost tends to be relatively small (since
relatively few declarations are ever deserialized).

This replaces a largish DenseMap within the AST reader. It's not
strictly a win in terms of memory use---not every declaration was
added to that DenseMap in the first place---but it's cleaner to have
this information available for every deserialized declaration, so that
future clients can rely on it.

different modules. This implementation is a first approximation of
what we want, using only the function type to determine
equivalence. Later, we'll want to deal with some of the more subtle
issues, including:

- C allows a prototyped declaration and a non-prototyped declaration
to be merged, which we should support
- We may want to ignore the return type when merging, then
complain if the return types differ. Or, we may want to leave it
as it us, so that we only complain if overload resolution
eventually fails.
- C++ non-static member functions need to consider cv-qualifiers
and ref-qualifiers.
- Function templates need to consider the template parameters and
return type.
- Function template specializations will have special rules.
- We can now (accidentally!) end up overloading in C, even without
the "overloadable" attribute, and will need to detect this at some
point.

The actual detection of "is this an overload?" is implemented by
Sema::IsOverload(), which will need to be moved into the AST library
for re-use here. That will be a future refactor.

or occurred in the translation unit loading the module. In this case,
we need to merge the two redeclaration chains immediately so that all
such declarations have the same canonical declaration in the resulting
AST (even though they don't in the module files we've imported).

Focusing on Objective-C classes until I'm happy with the design, then
I'll both (1) extend this notion to other kinds of declarations, and
(2) optimize away this extra checking when we're not dealing with
modules. For now, doing this checking for PCH files/preambles gives us
better testing coverage.

The new test establishes that we're building the redeclaration chains

definition itself was deserialized. The (separable) fix for that bug

variable is initialized by a non-constant expression, and pass in the variable
being declared so that earlier-initialized fields' values can be used.

Rearrange VarDecl init evaluation to make this possible, and in so doing fix a
long-standing issue in our C++ constant expression handling, where we would
mishandle cases like:

extern const int a;
const int n = a;
const int a = 5;
int arr[n];

Here, n is not initialized by a constant expression, so can't be used in an ICE,
even though the initialization expression would be an ICE if it appeared later

and saving that information in PCH files.

a1be278c4f3a234ff61f04018d26c6beecde1654 18-Dec-2011 Douglas Gregor <dgregor@apple.com> Completely re-implement (de-)serialization of declaration
chains. The previous implementation relied heavily on the declaration
chain being stored as a (circular) linked list on disk, as it is in
memory. However, when deserializing from multiple modules, the
different chains could get mixed up, leading to broken declaration chains.

The new solution keeps track of the first and last declarations in the
chain for each module file. When we load a declaration, we search all
of the module files for redeclarations of that declaration, then
splice together all of the lists into a coherent whole (along with any
redeclarations that were actually parsed).

As a drive-by fix, (de-)serialize the redeclaration chains of
TypedefNameDecls, which had somehow gotten missed previously. Add a
test of this serialization.

This new scheme creates a redeclaration table that is fairly large in
the PCH file (on the order of 400k for Cocoa.h's 12MB PCH file). The
table is mmap'd in and searched via a binary search, but it's still
quite large. A future tweak will eliminate entries for declarations
that have no redeclarations anywhere, and should
drastically reduce the size of this table.

53df7a1d34f21d8f2309311d1067d463e9064c60 15-Dec-2011 Douglas Gregor <dgregor@apple.com> Introduce the core infrastructure needed to model a complete
redeclaration chain for Objective-C classes, including:
- Using the first declaration as the canonical declaration.
- Using the definition as the primary DeclContext
- Making sure that all declarations have a pointer to the definition
data, and the definition knows that it is the definition.
- Serialization support for when a definition gets added to a
declaration that comes from an AST file.

However, note that we're not taking advantage of much of this code
yet, because we're still re-using ObjCInterfaceDecls.

2e5c15be82f362611c5928ce853d0685ff98c766 15-Dec-2011 Douglas Gregor <dgregor@apple.com> Move the definition-specific data of ObjCInterfaceDecl into a
separately-allocated DefinitionData structure, which we manage the
same way as CXXRecordDecl::DefinitionData. This prepares the way for
making ObjCInterfaceDecls redeclarable, to more accurately model
forward declarations of Objective-C classes and eliminate the mutation
of ObjCInterfaceDecl that causes us serious trouble in the AST reader.

Note that ObjCInterfaceDecl's accessors are fairly robust against
being applied to forward declarations, because Clang (and Sema in
particular) doesn't perform RequireCompleteType/hasDefinition() checks
everywhere it has to. Each of these overly-robust cases is marked with
a FIXME, which we can tackle over time.

Also modify the logic of how objc methods are getting passed to the consumer;
codegen depended on receiving objc methods before the implementation decl.
Since the interesting objc methods are ones with a body and such methods only
exist inside an ObjCImplDecl, deserialize and pass to consumer all the methods
of ObCImplDecl when we see one.

The initial incentive was to fix a crash when PCH chaining categories
to an interface, but the fix was done in the "modules way" that I hear
is popular with the kids these days.

Each module stores the local chain of categories and we combine them
when the interface is loaded. We also warn if non-dependent modules
introduce duplicate named categories.

0d95f77ba180aee35b74f3bf9f8543477f3af543 24-Aug-2011 Douglas Gregor <dgregor@apple.com> In the AST reader, switch name lookup within a DeclContect over to the
module DAG-based lookup scheme. This required some reshuffling, so
that each module stores its own mapping from DeclContexts to their
lexical and visible sets for those DeclContexts (rather than one big
"chain").

Overall, this allows simple qualified name lookup into the translation
unit to gather results from multiple modules, with the lookup results
in module B shadowing the lookup results in module A when B imports A.

Walking all of the lexical declarations in a module DAG is still a
mess; we'll end up walking the loaded module list backwards, which
works fine for chained PCH but doesn't make sense in a DAG. I'll
tackle this issue as a separate commit.

A new AST node is introduced: ClassScopeFunctionSpecialization. This node holds a FunctionDecl that is not yet specialized; then during the class template instantiation the ClassScopeFunctionSpecialization will spawn the actual function specialization.

Example:
template <class T>
class A {
public:
template <class U> void f(U p) { }
template <> void f(int p) { } // <== class scope specialization
};

This extension is necessary to parse MSVC standard C++ headers, MFC and ATL code.
BTW, with this feature in, clang can parse (-fsyntax-only) all the MSVC 2010 standard header files without any error.

declaration that never actually gets serialized. Instead, serialize
the various kinds of update records (lexical decls, visible decls, the

we're not chaining. This way, we won't have to deal with multiple

496c709a6f08f5c502b6f592ddd9ed40f953a5e5 03-Aug-2011 Douglas Gregor <dgregor@apple.com> Introduce the local -> global declaration ID mapping into the AST
reader, to allow AST files to be loaded with their declarations
remapped to different ID numbers. Fix a number of places where we were
either failing to map local declaration IDs into global declaration
IDs or where interpreting the local declaration IDs within the wrong
module.

I've tested this via the usual "random gaps" method. It works well
except for the preamble tests, because our handling of the precompiled
preamble requires declaration and preprocessed entity to be stable
when parsing code and then loading that back into memory. This
property will hold in general, but my randomized testing naturally
breaks this property to get more coverage. In the future, I expect
that the precompiled preamble logic won't need this property.

I am very unhappy with the current handling of the translation unit,
which is a rather egregious hack. We're going to have to do something
very different here for loading multiple AST files, because we don't
want to have to cope with merging two translation units. Likely, we'll
just handle translation units entirely via "update" records, and
predefine a single, fixed declaration ID for the translation
unit. That will come later.

so that we have one, simple way to map from global bit offsets to
local bit offsets. Eliminates a number of loops over the chain, and
generalizes for more interesting bit remappings.

Also, as an amusing oddity, we were computing global bit offsets
*backwards* for preprocessed entities (e.g., the directly included PCH
file in the chain would start at offset zero, rather than the original
PCH that occurs first in translation unit). Even more amusingly, it
made precompiled preambles work, because we were forgetting to adjust
the local bit offset to a global bit offset when storing preprocessed
entity offsets in the ASTUnit. Two wrongs made a right, and now
they're both right.

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

hasTrivialDefaultConstructor() really really means it now.

Also implement a fun standards bug regarding aggregates. Doug, if you'd
like, I can un-implement that bug if you think it is truly a defect.

The bug is that non-special-member constructors are never considered
user-provided, so the following is an aggregate:

struct foo {
foo(int);
};

It's kind of bad, but the solution isn't obvious - should

struct foo {
foo (int) = delete;
};

be an aggregate or not?

Lastly, add a missing initialization to FunctionDecl.

4fb86f8c4585e53c21c847ad3de9e3b2de123cd9 01-May-2011 Chandler Carruth <chandlerc@gmail.com> Re-applies the patch first applied way back in r106099, with
accompanying fixes to make it work today.

The core of this patch is to provide a link from a TemplateTypeParmType
back to the TemplateTypeParmDecl node which declared it. This in turn
provides much more precise information about the type, where it came
from, and how it functions for AST consumers.

To make the patch work almost a year after its first attempt, it needed
serialization support, and it now retains the old getName() interface.
Finally, it requires us to not attempt to instantiate the type in an
unsupported friend decl -- specifically those coming from template
friend decls but which refer to a specific type through a dependent
name.

A cleaner representation of the last item would be to build
FriendTemplateDecl nodes for these, storing their template parameters
etc, and to perform proper instantation of them like any other template
declaration. They can still be flagged as unsupported for the purpose of
access checking, etc.

This passed an asserts-enabled bootstrap for me, and the reduced test
case mentioned in the original review thread no longer causes issues,
likely fixed at somewhere amidst the 24k revisions that have elapsed.

a8225449421e8c1e996a7c48300521028946482a 30-Apr-2011 Chandler Carruth <chandlerc@gmail.com> Completely re-implement the core logic behind the __is_standard_layout
type trait. The previous implementation suffered from several problems:

1) It implemented all of the logic in RecordType by walking over every
base and field in a CXXRecordDecl and validating the constraints of
the standard. This made for very straightforward code, but is
extremely inefficient. It also is conceptually wrong, the logic tied
to the C++ definition of standard-layout classes should be in
CXXRecordDecl, not RecordType.
2) To address the performance problems with #1, a cache bit was added to
CXXRecordDecl, and at the completion of every C++ class, the
RecordType was queried to determine if it was a standard layout
class, and that state was cached. Two things went very very wrong
with this. First, the caching version of the query *was never
called*. Even within the recursive steps of the walk over all fields
and bases the caching variant was not called, making each query
a full *recursive* walk. Second, despite the cache not being used, it
was computed for every class declared, even when the trait was never
used in the program. This probably significantly regressed compile
time performance for edge-case files.
3) An ASTContext was required merely to query the type trait because
querying it performed the actual computations.
4) The caching bit wasn't managed correctly (uninitialized).

The new implementation follows the system for all the other traits on
C++ classes by encoding all the state needed in the definition data and
building up the trait incrementally as each base and member are added to
the definition of the class.

The idiosyncracies of the specification of standard-layout classes
requires more state than I would like; currently 5 bits. I could
eliminate one of the bits easily at the expense of both clarity and
resilience of the code. I might be able to eliminate one of the other
bits by computing its state in terms of other state bits in the
definition. I've already done that in one place where there was a fairly
simple way to achieve it.

It's possible some of the bits could be moved out of the definition data
and into some other structure which isn't serialized if the serialized
bloat is a problem. That would preclude serialization of a partial class
declaration, but that's likely already precluded.

Comments on any of these issues welcome.

Also, if there are any, tell the context that it has external visible decls. This fixes the problem that a namespace that was empty in the initial PCH (could also happen if the initial PCH didn't include any std header but caused implicit creation of namespace std, e.g. due to implicit declaration of a virtual destructor) never found any declaration declared in *any* chained PCH. Very ugly when the chained PCH includes all that std stuff, as the errors were effectively the same as not including std headers.

4d6e5a22d9481bb83b82d911727540096d171c0b 24-Apr-2011 Chandler Carruth <chandlerc@gmail.com> Begin tracking trivialness of move constructors and move assignment
operators in C++ record declarations.

This patch starts off by updating a bunch of the standard citations to
refer to the draft 0x standard so that the semantics intended for move
varianst is clear. Where necessary these are duplicated so they'll be
available in doxygen.

It adds bit fields to keep track of the state for the move constructs,
and updates all the code necessary to track this state (I think) as
members are declared for a class. It also wires the state into the
various trait-like accessors in the AST's API, and tests that the type
trait expressions now behave correctly in the presence of move
constructors and move assignment operators.

This isn't complete yet due to these glaring FIXMEs:
1) No synthesis of implicit move constructors or assignment operators.
2) I don't think we correctly enforce the new logic for both copy and
move trivial checks: that the *selected* copy/move
constructor/operator is trivial. Currently this requires *all* of them
to be trivial.
3) Some of the trait logic needs to be folded into the fine-grained
trivial bits to more closely match the wording of the standard. For
example, many of the places we currently set a bit to track POD-ness
could be removed by querying other more fine grained traits on
demand.

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() { }

use the translation unit as its declaration context, then deserialize
the actual lexical and semantic DeclContexts after the template
parameter is complete. This avoids problems when the DeclContext
itself (e.g., a class template) is dependent on the template parameter
(e.g., for the injected-class-name).

9a299e0575ce235f491014627c7267e2d2cd73de 04-Mar-2011 Douglas Gregor <dgregor@apple.com> Make sure to put template parameters into their owning template's
DeclContext once we've created it. This mirrors what we do for
function parameters, where the parameters start out with
translation-unit context and then are adopted by the appropriate
DeclContext when it is created. Also give template parameters public
access and make sure that they don't show up for the purposes of name
lookup.

Fixes PR9400, a regression introduced by r126920, which implemented
substitution of default template arguments provided in template
template parameters (C++ core issue 150).

How on earth could the DeclContext of a template parameter affect the
handling of default template arguments?

I'm so glad you asked! The link is
Sema::getTemplateInstantiationArgs(), which determines the outer
template argument lists that correspond to a given declaration. When
we're instantiating a default template argument for a template
template parameter within the body of a template definition (not it's
instantiation, per core issue 150), we weren't getting any outer
template arguments because the context of the template template
parameter was the translation unit. Now that the context of the
template template parameter is its owning template, we get the
template arguments from the injected-class-name of the owning
template, so substitution works as it should.

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.

a97d70b7ea9633e8cbf976510d7a9ea66f4ac96c 21-Jan-2011 Peter Collingbourne <peter@pcc.me.uk> Generalise support for non-inheritable attributes

Inheritable attributes on declarations may be inherited by any later
redeclaration at merge time. By contrast, a non-inheritable attribute
will not be inherited by later redeclarations. Non-inheritable
attributes may be semantically analysed early, allowing them to
influence the redeclaration/overloading process.

Before this change, the "overloadable" attribute received special
handling to be treated as non-inheritable, while all other attributes
were treated as inheritable. This patch generalises the concept,
while removing a FIXME. Some CUDA location attributes are also marked
as non-inheritable in order to support special overloading semantics
(to be introduced in a later patch).

The patch introduces a new Attr subclass, InheritableAttr, from
which all inheritable attributes derive. Non-inheritable attributes
simply derive from Attr.

N.B. I did not review every attribute to determine whether it should
be marked non-inheritable. This can be done later on an incremental
basis, as this change does not affect default functionality.

a pack expansion, e.g., the parameter pack Values in:

template<typename ...Types>
struct Outer {
template<Types ...Values>
struct Inner;
};

This new implementation approach introduces the notion of an
"expanded" non-type template parameter pack, for which we have already
expanded the types of the parameter pack (to, say, "int*, float*",
for Outer<int*, float*>) but have not yet expanded the values. Aside
from creating these expanded non-type template parameter packs, this
patch updates template argument checking and non-type template
parameter pack instantiation to make use of the appropriate types in
the parameter pack.

1ab55e9bb87d98bff1d42c7a0ee502c64755d9f5 10-Dec-2010 Douglas Gregor <dgregor@apple.com> Eliminate the branching in QualType::getTypePtr() by providing a
common base for ExtQuals and Type that stores the underlying type
pointer. This results in a 2% performance win for -emit-llvm on a
typical C file, with 1% memory growth in the AST.

Note that there is an API change in this optimization:
QualType::getTypePtr() can no longer be invoked on a NULL
QualType. If the QualType might be NULL, use
QualType::getTypePtrOrNull(). I've audited all uses of getTypePtr() in
the code base and changed the appropriate uses over to
getTypePtrOrNull().

A future optimization opportunity would be to distinguish between
cast/dyn_cast and cast_or_null/dyn_cast_or_null; for the former, we
could use getTypePtr() rather than getTypePtrOrNull(), to take another
branch out of the cast/dyn_cast implementation.

381d34e0b205ca27bcc7e7c1652561941c437965 06-Dec-2010 Douglas Gregor <dgregor@apple.com> Re-implement caching for the linkage calculation of declarations.

My previous attempt at solving the compile-time problem with many
redeclarations of the same entity cached both linkage and visibility,
while this patch only tackles linkage. There are several reasons for
this difference:

- Linkage is a language concept, and is evaluated many times during
semantic analysis and codegen, while visibility is only a
code-generation concept that is evaluated only once per (unique)
declaration. Hence, we *must* optimize linkage calculations but
don't need to optimize visibility computation.
- Once we know the linkage of a declaration, subsequent
redeclarations can't change that linkage. Hence, cache
invalidation is far simpler than for visibility, where a later
redeclaration can completely change the visibility.
- We have 3 spare bits in Decl to store the linkage cache, so the
cache doesn't increase the size of declarations. With the
visibility+linkage cache, NamedDecl got larger.

2357207a5753547740c70a12c3b37f71afa93f8a 03-Dec-2010 Douglas Gregor <dgregor@apple.com> Implement caching for the linkage and visibility calculations of
declarations.

The motivation for this patch is that linkage/visibility computations
are linear in the number of redeclarations of an entity, and we've run
into a case where a single translation unit has > 6500 redeclarations
of the same (unused!) external variable. Since each redeclaration
involves a linkage check, the resulting quadratic behavior makes Clang
slow to a crawl. With this change, a simple test with 512
redeclarations of a variable syntax-checks ~20x faster than
before.

That said, I hate this change, and will probably end up reverting it
in a few hours. Reasons to hate it:
- It makes NamedDecl larger, since we don't have enough free bits in
Decl to squeeze in the extra information about caching.
- There are way too many places where we need to invalidate this
cache, because the visibility of a declaration can change due to
redeclarations (!). Despite self-hosting and passing the testsuite,
I have no confidence that I've found all of places where this cache
needs to be invalidated.

PCH got a severe beating by the boost-using test case reported here: http://llvm.org/PR8099
Fix issues like:

-When PCH reading, make sure Decl's getASTContext() doesn't get called since a Decl in the parent hierarchy may be initializing.
-In ASTDeclReader::VisitFunctionDecl VisitRedeclarable should be called before using FunctionDecl's isCanonicalDecl()
-In ASTDeclReader::VisitRedeclarableTemplateDecl CommonOrPrev must be initialized before anything else.

7e24256c95afb64b4d5abf201a0f9f0527cb4cf3 01-Sep-2010 Douglas Gregor <dgregor@apple.com> Implement libclang support for using declarations. Clang actually uses
three different kinds of AST nodes to represent using declarations:
UsingDecl, UnresolvedUsingValueDecl, and
UnresolvedUsingTypenameDecl. These three are collapsed into a single
cursor kind for using declarations, since libclang clients don't need
the distinction.

Several related changes here:
- Cursor visitation of the three AST nodes for using declarations
- Proper source-range computation for these AST nodes
- Using declarations have no USRs, since they don't actually declare
any entities.

53b9441b5a81a24fa1f66f3f6416f1e36baa9c2f 01-Sep-2010 Ted Kremenek <kremenek@apple.com> Split ObjCInterfaceDecl::ReferencedProtocols into two lists: ReferencedProtocols and AllReferencedProtocols. ReferencedProtocols
(and thus protocol_begin(), protocol_end()) now only contains the list of protocols that were directly referenced in
an @interface declaration. 'all_referenced_protocol_[begin,end]()' now returns the set of protocols that were referenced
in both the @interface and class extensions. The latter is needed for semantic analysis/codegen, while the former is
needed to maintain the lexical information of the original source.

8ea5b9d832455247a15925398fb663d299d33238 01-Sep-2010 Douglas Gregor <dgregor@apple.com> Improve location information in the representation of namespace
aliases. Previously, the location of the alias was at the "namespace"
keyword. Now, it's on the identifier being declared (as is the custom
for Clang), and we keep a separate source location for the "namespace"
keyword.

Also, added a getSourceRange() member function to NamespaceAliasDecl
to correctly compute the source range.

Finally, removed a bunch of setters from NamespaceAliasDecl and gave
ASTReaderDecl friendship so that it could set the corresponding fields
directly.

*Huge* improvement over the amount of deserializing that we do for C++ lookup.
e.g, if he have the Carbon header precompiled and include it on a file containing this:

int x;

these are the before/after stats:

548/30654 source location entries read (1.787695%)

AFTER using the on-disk table:
