simplify and cleanup global variable creation stuff to all go through one
code path.

llvm-svn: 67445

simplify management of llvm::Function creation to all go through
GetAddrOfFunction. This is simpler and more efficient.

llvm-svn: 67444

code cleanups, rename EmitForwardFunctionDefinition ->
CreateFunctionPrototypeIR, though my next patch will eliminate
it entirely.

fix several problems with asm renaming, by pulling it into the mangling code:

1. it wasn't applying to definitions, only declarations, e.g. int x __asm("foo")
2. multiple definitions were conflictin

fix several problems with asm renaming, by pulling it into the mangling code:

1. it wasn't applying to definitions, only declarations, e.g. int x __asm("foo")
2. multiple definitions were conflicting, they weren't getting merged.
3. the code was duplicated in several places.

add some fixmes

llvm-svn: 67441

reduce redundant calls of getMangledName.

llvm-svn: 67440

simplify some more code.

llvm-svn: 67439

simplify and comment some code better. Make BindRuntimeGlobals
more optimistic that it will work (optimizing for the common case).

llvm-svn: 67438

random code cleanups.

llvm-svn: 67437

remove obviously dead code: you can't bitcast a pointer to "Ty" (a function type).

llvm-svn: 67436

avoid making constant folding logic eliminate obviously dead bitcasts, speeding up PR3810
by ~2%.

llvm-svn: 67434

Add a fast path to CodeGenModule::getMangledName for almost all C functions,
speeding up the testcase in PR3810 by 60%.

llvm-svn: 67431

IRgen support for alias of global variable.
- PR3818.

llvm-svn: 67297

objc: Implemented variables declared in class interface
whose sema decl is at the translation unit.

llvm-svn: 67249

Adjust for linkage name change.

llvm-svn: 66691

Correct for change of this name in LLVM.

llvm-svn: 66652

Backout r66408, we don't want handling of globals to rely on the
module symbol table. The root problem inspiring this was fixed in
r66316 (and again in r66506).

llvm-svn: 66512

Be sure to never create two functions with the same name, instead arrange to
reuse the prior one.

llvm-svn: 66408

Make constant emission for @encode use the common string emission code.
This is a bit cleaner, and also "fixes" bad code that compares the
addresses of the string constants.

llvm-svn: 66346

Fixup our uses of various linkages to match how llvm now works. I think they are all
correct, but an extra set of ObjC eyes would be good.

(LLVM svn up) Generalize RuntimeFunctions to RuntimeGlobals and add
CodeGenModule::CreateRuntimeVariable.

- No real functionality change; although we now assert on silly
things like:
--
int objc

IRgen support for weak_import.

Don't mangle names of local variables.
- For one thing, this adds unneeded overhead; for another, this
routine can be used to emit unnamed decls which we shouldn't try to
mangle.

Make IRGen compatible with declaring a function with incomplete
return/argument types. (The generated IR isn't ideal, but we can't
really do better in general.)
