Chris Lattner ad3467ee89 The -fshort-wchar option causes wchar_t to become unsigned, in addition to being 
16-bits in size.  Implement this by splitting WChar into two enums, like we have
for char.  This fixes a miscompmilation of XULRunner, PR8856.

John McCall 86353416a7 The ARM C++ ABI is sufficiently different from the Itanium C++ ABI that 
it deserves its own enumerator.  Obviously the implementations should
closely follow the Itanium ABI except in cases of divergence.

Daniel Dunbar 6f2e839693 CodeGen/ObjC/NeXT: Fix Obj-C message send to match llvm-gcc when choosing

Chris Lattner 1a8f394a1f david conrad points out that {|} in inline assembly on arm are not asm

 2010-04-15 15:06:18 +00:00
Daniel Dunbar 3d9289c736 Add TargetInfo::useBitfieldTypeAlignment(). 
- Used to determine whether the alignment of the type in a bit-field is
   respected when laying out structures. The default is true, targets can
   override this as needed.

 - This is designed to correspond to the PCC_BITFIELD_TYPE_MATTERS macro in
   gcc. The AST/Sema implementation only affects one line, unless I have
   forgotten something. I'd appreciate further review.

 - IRgen still needs to be updated to fully support this (which is effectively
   PR5591).

Eli Friedman 2857ccbaa7 Fix for PR4192: fix the definition of int64_t on x86_64 Linux. 
Note that I'm guessing that *BSD and Solaris do the same thing as Linux 
here, but it's quite possible I'm wrong; if the following testcase 
gives an error on x86-64 with gcc for any of those operating systems, please
tell me:

#include <stdint.h>

int64_t x; long x;

Eli Friedman d88c8a104f Add target property for whether thread-local storage is supported. 
Let me know if I messed up for some target.  Note that for Windows, we 
should be able to support it (MSVC supports "__declspec(thread)"), but 
I'm pretty sure LLVM doesn't know how to generate the correct code.

Chris Lattner 7e4c81c8c6 Give TargetInfo a new IntPtrType to hold the intptr_t type for

On linux/32, set intptr_t to int, instead of long.  This fixes PR3563.
