Fixed crasher in <rdar://problem/6780904> [irgen] Assertion failed: (Result == conversionOK && "UTF-8 to UTF-16 conversion failed"), function GetAddrOfConstantCFString, file CodeGenModule.cpp, line 1063.

Still a diagnostic related FIXME (will discuss with Daniel/Fariborz offline).

their emission was deferred.
 - <rdar://problem/6775234> variables with internal linkage should not
   be exposed with -fvisibility=hidden.

llvm-svn: 68818

llvm-svn: 68755

No functionality change (really).

llvm-svn: 68726

Add a destination type argument to EmitConstantExpr. This will be used for when the destination has a reference type. (No functionality change yet)

llvm-svn: 68593

llvm-svn: 68561

 - Changed method names to match gcc (categories names still aren't
   mangled in).

 - Expose correct name for class and metadata symbols (although
   -fvisibility=hidden isn't yet correct).

 - Remove several things from llvm.used that didn't need to be there
   (I suspect this can still be trimmed).

 - Don't use asm-prefix extension for _objc_empty_{cache,vtable} (not
   needed).

 - Hide EH type class info with -fvisibility=hidden

 - Change setGlobal[Option]Visibility to not change the visibility of
   functions with internal linkage.

string literals.

llvm-svn: 68363

llvm-svn: 68300

- Finish up support for converting UTF8->UTF16 to support ObjC @"string" constants.

Remove warning from CheckObjCString.

As the FIXME in the test case indicates, I still have a bug to work out (apparently with \u handling).

llvm-svn: 68245

#ifdef'd out the 5 conversion routines that we don't currently need.

Still need a bit more work in GetAddrOfConstantCFString(). Added a FIXME to indicate this.

Expect to remove the FIXME today...

Patch by Jean-Daniel Dupas. Thanks!

types get completed when their definition is seen if previously laid out by
the code generator.

 - Notably, set section on cfstring literal string data (for now, this
   is done everywhere because it matches what we were already doing
   for the CFString data itself)

 - <rdar://problem/6599098> [irgen] linker requires objc string data
   to go into cstring

attribute(used) and asm renaming are used together.

remove a redundant error in CodeGen.

llvm-svn: 67868

ir gen. No intended change in functionality.

llvm-svn: 67857

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 {

speeding up the testcase in PR3810 by 3.8%

llvm-svn: 67457

llvm-svn: 67450

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

GetAddrOfFunction.  This is simpler and more efficient.

llvm-svn: 67444

CreateFunctionPrototypeIR, though my next patch will eliminate
it entirely.

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.
