attribute(used) and asm renaming are used together.

Do not emit debug information for variables while generating optimized code.  The llvm optimizer and code generator are not yet ready to support optimized code debugging.

llvm-svn: 67876

CodeGenModule.  Once there, add a new NoCommon option to
it and implement -fno-common.

llvm-svn: 67735

functionality, fixing a crash on the attached testcase.  Eliminate the
BuiltinFunctions cache, as it can contain dangling pointers.  This fixes
a bunch of valgrind errors on test/CodeGen/builtins.c

llvm-svn: 67484

the end of the module.

llvm-svn: 67482

No intended functionality change.

llvm-svn: 67478

very simple places, reimplement the deferred decl emission logic to not be O(N^2),
fixing PR3810.

llvm-svn: 67447

function definition.

llvm-svn: 67446

code path.

llvm-svn: 67445

GetAddrOfFunction.  This is simpler and more efficient.

llvm-svn: 67444

CreateFunctionPrototypeIR, though my next patch will eliminate
it entirely.

llvm-svn: 67443

llvm-svn: 67439

more optimistic that it will work (optimizing for the common case).

llvm-svn: 67438

 - PR3818.

llvm-svn: 67297

module symbol table. The root problem inspiring this was fixed in
r66316 (and again in r66506).

llvm-svn: 66512

reuse the prior one.

llvm-svn: 66408

llvm-svn: 66335

CodeGenModule::CreateRuntimeVariable.

 - No real functionality change; although we now assert on silly
   things like:
--
int objc_exception_throw;
void f0() { @throw(@"A"); }
--
   instead of accepting it.

llvm-svn: 66292

llvm-svn: 66046

BlockModule.  No functionality change.  This should help people that
don't want to know anything about blocks not be confused by the
overloaded use of the term block or nor want to see all the blocks
goop.

llvm-svn: 66042

people.  De-duplicates BLOCK_NEEDS_FREE and friends.

llvm-svn: 66034

still give an unsupported error for them due to the fact this is a
work in progress.

llvm-svn: 66007

we ensure that things added to the module can be found even when they
are not in GlobalDeclMap.  The later is for increased flexibility,
should someone want to do something tricky like extern "Ada" in the
same module.

llvm-svn: 65657

The big difference here is that (like string literal) @encode has 
array type, not pointer type.

 - <rdar://problem/6584606> clang/x86-64 - too many reg saves

llvm-svn: 65032

The size calculation is improved.

llvm-svn: 64994

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.

Thanks Anders.

 - Fix emission of static functions with constructor attribute while I
   was here.
<rdar://problem/6140899> [codegen] "static" and attribute-constructor interact poorly

llvm-svn: 64488

for attribute used support.  
- No functionality change.
