remove a redundant error in CodeGen.

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

BuiltinFunctions cache, as it can contain dangling pointers.  This fixes
a bunch of valgrind errors on test/CodeGen/builtins.c

the end of the module.

No intended functionality change.

to something like:
define void @bar(%struct.foo* noalias sret %agg.result) nounwind {
instead of:
define void @bar(%struct.foo* noalias sret %agg.result, ...) nounwind {

ctor function.  This avoids creating a temporary std::string for the name,
speeding up the testcase in PR3810 by 3.8%

llvm-svn: 67457

category or protocol.

llvm-svn: 67450

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

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.

r66316 (and again in r66506).

llvm-svn: 66512

reuse the prior one.

llvm-svn: 66408

This is a bit cleaner, and also "fixes" bad code that compares the 
addresses of the string constants.

llvm-svn: 66346

correct, but an extra set of ObjC eyes would be good.

llvm-svn: 66342

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

 - <rdar://problem/6652110> clang should support weak_import

llvm-svn: 66270

 - 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.

llvm-svn: 66212

return/argument types.  (The generated IR isn't ideal, but we can't 
really do better in general.)
