993f43f24d7a45a5cd4678a3316b0852261fc5d4 06-May-2013 John McCall <rjmccall@apple.com> Grab-bag of bit-field fixes:

- References to ObjC bit-field ivars are bit-field lvalues;
fixes rdar://13794269, which got me started down this.
- Introduce Expr::refersToBitField, switch a couple users to
it where semantically important, and comment the difference
between this and the existing API.
- Discourage Expr::getBitField by making it a bit longer and
less general-sounding.
- Lock down on const_casts of bit-field gl-values until we
hear back from the committee as to whether they're allowed.

Doxygen treats "@command" the same as "\command" in a doc comment, so
whenever we talk about Objective-C things like "@interface" we have to
make sure to escape them.

Let's try to keep Clang -Wdocumentation-clean!

This reduces the number of warnings generated by Doxygen by about 100
(roughly 10%). Issues addressed:
(1) Primarily, backslash-escaped "@foo" and "#bah" in Doxygen comments
when they're not supposed to be Doxygen commands or links, and
similarly for "<baz>" when it's not intended as as HTML tag;
(2) Changed some \t commands (which don't exist) to \c ("to refer to a
word of code", as the Doxygen manual says);
(3) \precondition becomes \pre;
(4) When touching comments, deleted a couple of spurious spaces in them;
(5) Changed some \n and \r to \\n and \\r;
(6) Fixed one tiny typo: #pragms -> #pragma.

This patch touches documentation/comments only.

b085d898bdfe35097eba45f4072b0f6865f561dc 30-Mar-2012 Argyrios Kyrtzidis <akyrtzi@gmail.com> Add info to ObjCPropertyRefExpr to indicate whether the dot syntax property
reference is going to message the setter, the getter, or both.

Having this info on the ObjCPropertyRefExpr node makes it easier for AST
clients (like libclang) to reason about the meaning of the property reference.

-Use 2 bits (with a PointerIntPair) in ObjCPropertyRefExpr to record the above info
-Have ObjCPropertyOpBuilder set the info appropriately.

-When there is an implicit property reference (property syntax using methods)
have clang_getCursorReferenced return a cursor for the method. If the property
reference is going to result in messaging both the getter and the setter choose
to return a cursor for the setter because it is less obvious from source inspection
that the setter is getting called.

The general idea has the seal of approval by John.

- The theory here is that we have these functions sprinkled in all over the
place. This should allow the optimizer to at least realize it can still do
load CSE across these calls.
- I blindly marked all instances as such, even though the optimizer can infer
this attribute in some instances (some of the inline ones) as that was easier
and also, when given the choice between thinking and not thinking, I prefer
the latter.

You might think this is mere frivolity, but actually this is good for a .7 -

ebcb57a8d298862c65043e88b2429591ab3c58d3 06-Mar-2012 Ted Kremenek <kremenek@apple.com> Add clang support for new Objective-C literal syntax for NSDictionary, NSArray,
NSNumber, and boolean literals. This includes both Sema and Codegen support.
Included is also support for new Objective-C container subscripting.

My apologies for the large patch. It was very difficult to break apart.
The patch introduces changes to the driver as well to cause clang to link
in additional runtime support when needed to support the new language features.

Docs are forthcoming to document the implementation and behavior of these features.

a1b852f8e1bee5ed3604ee483803cef39ce57a20 25-Oct-2011 John McCall <rjmccall@apple.com> Introduce a placeholder type for "pseudo object"
expressions: expressions which refer to a logical rather
than a physical l-value, where the logical object is
actually accessed via custom getter/setter code.
A subsequent patch will generalize the AST for these
so that arbitrary "implementing" sub-expressions can
be provided.

Right now the only client is ObjC properties, but
this should be generalizable to similar language
features, e.g. Managed C++'s __property methods.

561f81243f665cf2001caadc45df505f826b72d6 01-Jul-2011 Douglas Gregor <dgregor@apple.com> Introduce the notion of instantiation dependence into Clang's AST. A
type/expression/template argument/etc. is instantiation-dependent if
it somehow involves a template parameter, even if it doesn't meet the
requirements for the more common kinds of dependence (dependent type,
type-dependent expression, value-dependent expression).

When we see an instantiation-dependent type, we know we always need to
perform substitution into that instantiation-dependent type. This
keeps us from short-circuiting evaluation in places where we
shouldn't, and lets us properly implement C++0x [temp.type]p2.

In theory, this would also allow us to properly mangle
instantiation-dependent-but-not-dependent decltype types per the
Itanium C++ ABI, but we aren't quite there because we still mangle
based on the canonical type in cases like, e.g.,

template<unsigned> struct A { };
template<typename T>
void f(A<sizeof(sizeof(decltype(T() + T())))>) { }
template void f<int>(A<sizeof(sizeof(int))>);

and therefore get the wrong answer.

there were only three virtual methods of any significance.

The primary way to grab child iterators now is with
Stmt::child_range children();
Stmt::const_child_range children() const;
where a child_range is just a std::pair of iterators suitable for
being llvm::tie'd to some locals. I've left the old child_begin()
and child_end() accessors in place, but it's probably a substantial
penalty to grab the iterators individually now, since the
switch-based dispatch is kindof inherently slower than vtable
dispatch. Grabbing them together is probably a slight win over the
status quo, although of course we could've achieved that with vtables, too.

I also reclassified SwitchCase (correctly) as an abstract Stmt
class, which (as the first such class that wasn't an Expr subclass)
required some fiddling in a few places.

There are somewhat gross metaprogramming hooks in place to ensure
that new statements/expressions continue to implement
getSourceRange() and children(). I had to work around a recent clang
bug; dgregor actually fixed it already, but I didn't want to
introduce a selfhosting dependency on ToT.

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.

2725ca8eb3354975ca77ed4b88ede7b60b216b9a 21-Apr-2010 Douglas Gregor <dgregor@apple.com> Rework the Parser-Sema interaction for Objective-C message
sends. Major changes include:

- Expanded the interface from two actions (ActOnInstanceMessage,
ActOnClassMessage), where ActOnClassMessage also handled sends to
"super" by checking whether the identifier was "super", to three
actions (ActOnInstanceMessage, ActOnClassMessage,
ActOnSuperMessage). Code completion has the same changes.
- The parser now resolves the type to which we are sending a class
message, so ActOnClassMessage now accepts a TypeTy* (rather than
an IdentifierInfo *). This opens the door to more interesting
types (for Objective-C++ support).
- Split ActOnInstanceMessage and ActOnClassMessage into parser
action functions (with their original names) and semantic
functions (BuildInstanceMessage and BuildClassMessage,
respectively). At present, this split is onyl used by
ActOnSuperMessage, which decides which kind of super message it
has and forwards to the appropriate Build*Message. In the future,
Build*Message will be used by template instantiation.
- Use getObjCMessageKind() within the disambiguation of Objective-C
message sends vs. array designators.

Two notes about substandard bits in this patch:
- There is some redundancy in the code in ParseObjCMessageExpr and
ParseInitializerWithPotentialDesignator; this will be addressed
shortly by centralizing the mapping from identifiers to type names
for the message receiver.
- There is some #if 0'd code that won't likely ever be used---it
handles the use of 'super' in methods whose class does not have a
superclass---but could be used to model GCC's behavior more
closely. This code will die in my next check-in, but I want it in

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

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.

277073 clang - Number of checks for C++ declaration nodes

18 clang - Number of checks for C++ statement nodes
174182 clang - Number of checks for C++ type nodes

9800 clang - Number of checks for Objective-C expression nodes
7 clang - Number of checks for Objective-C statement nodes

they introduce potentially-expensive operations into very low-level

a8fa96e366ab36145a5500dd4fbea717c217f131 03-Feb-2010 David Chisnall <csdavec@swan.ac.uk> Numerous changes to selector handling:

- Don't use GlobalAliases with non-0 GEPs (GNU runtime) - this was unsupported and LLVM will be generating errors if you do it soon. This also simplifies the code generated by the GNU runtime a bit.

- Make GetSelector() return a constant (GNU runtime), not a load of a store of a constant.

- Recognise @selector() expressions as valid static initialisers (as GCC does).

- Add methods to GCObjCRuntime to emit selectors as constants (needed for using @selector() expressions as constants. These need implementing for the Mac runtimes - I couldn't figure out how to do this, they seem to require a load.

- Store an ObjCMethodDecl in an ObjCSelectorExpr so that we can get at the type information for the selector. This is needed for generating typed selectors from @selector() expressions (as GCC does). Ideally, this information should be stored in the Selector, but that would be an invasive change. We should eventually add checks for common uses of @selector() expressions. Possibly adding an attribute that can be applied to method args providing the types of a selector so, for example, you'd do something like this:

- (id)performSelector: __attribute__((selector_types(id, SEL, id)))(SEL)
withObject: (id)object;

Then, any @selector() expressions passed to the method will be check to ensure that it conforms to this signature. We do this at run time on the GNU runtime already, but it would be nice to do it at compile time on all runtimes.

- Made @selector() expressions emit type info if available and the runtime supports it.

Someone more familiar with the Mac runtime needs to implement the GetConstantSelector() function in CGObjCMac. This currently just assert()s.

- Fix the names of VisitObjCAtCatchStmt and VisitObjCAtFinallyStmt
in the PCH reader and writer; these were never getting called.

At this point, all of the pch-test tests pass for C and Objective-C.

- Implement RewritePropertySetter(). While the routine is simple, there were some tricky changes to RewriteFunctionBodyOrGlobalInitializer(), the main rewriter loop.

- Implement FIXME: for pretty printing ObjCPropertyRefExpr's.

- Changed ObjCPropertyRefExpr::getSourceRange() to point to the end of the property name (not the beginning). Also made a minor name change from "Loc"->"IdLoc" (to make it clear the Loc does not point to the ".").

5549976193e34417d4474a5f4a514268ef6666c7 17-Jun-2008 Ted Kremenek <kremenek@apple.com> This patch is motivated by numerous strict-aliasing warnings when compiling
clang as a Release build.

The big change is that all AST nodes (subclasses of Stmt) whose children are
Expr* store their children as Stmt* or arrays of Stmt*. This is to remove
strict-aliasing warnings when using StmtIterator. None of the interfaces of any
of the classes have changed (except those with arg_iterators, see below), as the
accessor methods introduce the needed casts (via cast<>). While this extra
casting may seem cumbersome, it actually adds some important sanity checks
throughout the codebase, as clients using StmtIterator can potentially overwrite
children that are expected to be Expr* with Stmt* (that aren't Expr*). The casts
provide extra sanity checks that are operational in debug builds to catch
invariant violations such as these.

For classes that have arg_iterators (e.g., CallExpr), the definition of
arg_iterator has been replaced. Instead of it being Expr**, it is an actual
class (called ExprIterator) that wraps a Stmt**, and provides the necessary
operators for iteration. The nice thing about this class is that it also uses
cast<> to type-checking, which introduces extra sanity checks throughout the
codebase that are useful for debugging.

A few of the CodeGen functions that use arg_iterator (especially from
OverloadExpr) have been modified to take begin and end iterators instead of a
base Expr** and the number of arguments. This matches more with the abstraction
of iteration. This still needs to be cleaned up a little bit, as clients expect
that ExprIterator is a RandomAccessIterator (which we may or may not wish to
allow for efficiency of representation).

This is a fairly large patch. It passes the tests (except CodeGen/bitfield.c,
which was already broken) on both a Debug and Release build, but it should
obviously be reviewed.
