If a function definition has any sort of weak linkage, its static local
...
variables should have that linkage. Otherwise, its static local
variables should have internal linkage. To avoid computing this excessively,
set a function's linkage before we emit code for it.
Previously we were assigning weak linkage to the static variables of
static inline functions in C++, with predictably terrible results. This
fixes that and also gives better linkage than 'weak' when merging is required.

Change CodeGenModule to rely on the Module's symbol table instead of

Forces us to do string lookups instead of pointer lookups, which might hurt
codegen times a little across the board. We'll see how it plays out.
Removing the string-uniquing requirement implicitly fixes any bugs like
PR6635 which arose from the fact that we had multiple uniquing tables for
different kinds of identifiers.

Fixup debug information for the location information for __block

variables. For this to work, the backend needs to handle more complex
forms for locations.
A typical utterance would be:
%forwarding = getelementptr %0* %use_by_ref, i32 0, i32 1 ; <i8**> [#uses=1]
%0 = load i8** %forwarding ; <i8*> [#uses=1]
%1 = bitcast i8* %0 to %0* ; <%0*> [#uses=1]
%x = getelementptr %0* %1, i32 0, i32 4 ; <i32*> [#uses=1]
%2 = bitcast i32* %x to { }* ; <{ }*> [#uses=1]
call void @llvm.dbg.declare({ }* %2, { }* bitcast (%llvm.dbg.variable.type* @llvm.dbg.variable to { }*))
Presently when selection finds something it doesn't understand, it
just avoids generating any information, which is safe, just
incomplete. Radar 6867696

extern A __attribute__((visibility("hidden")))

Change EmitConstantExpr to allow failure.

IRgen no longer relies on isConstantInitializer, instead we just try
to emit the constant. If that fails then in C we emit an error
unsupported (this occurs when Sema accepted something that it doesn't
know how to fold, and IRgen doesn't know how to emit) and in C++ we
emit a guarded initializer.
This ends up handling a few more cases, because IRgen was actually
able to emit some of the constants Sema accepts but can't Evaluate().
For example, PR3398.

Add basic support for C++ name mangling according to the Itanium C++
...
ABI to the CodeGen library. Since C++ code-generation is so
incomplete, we can't exercise much of this mangling code. However, a
few smoke tests show that it's doing the same thing as GCC. When C++
codegen matures, we'll extend the ABI tester to verify name-mangling
as well, and complete the implementation here.
At this point, the major client of name mangling is in the uses of the
new "overloadable" attribute in C, which allows overloading. Any
"overloadable" function in C (or in an extern "C" block in C++) will
be mangled the same way that the corresponding C++ function would be
mangled.

Remove FileVarDecl and BlockVarDecl. They are replaced by VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl().
...
This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it).

Since isComplexType() no longer returns true for _Complex integers, the code

generator needs to call isAnyComplexType(). This fixes PR1960.

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.
