2009-05-29Add code for emitting C++ destructors. Not used yet.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72591 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-29Create a new PrintingPolicy class, which we pass down through the ASTDouglas Gregor
printing logic to help customize the output. For now, we use this rather than a special flag to suppress the "struct" when printing "struct X" and to print the Boolean type as "bool" in C++ but "_Bool" in C. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72590 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-29Re-add a slightly more general version of the check from r72578; it is Eli Friedman
actually necessary in some obscure cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72585 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-29Oops, the testcase I was thinking of is supposed to error out. IMike Stump
tried other things that might trip, but they all worked. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72584 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-29Fixup the rest of the trivial cases of the codegen of volatile. IfMike Stump
any body can spot codegen bugs with volatile, or knows of any in the bug database, let me know. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72572 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-28PR4281: Fix bogus CodeGen assertion. The issue is that Eli Friedman

2009-05-26When trying to pass an argument on the stack, assume LLVM will do the rightDaniel Dunbar
thing for non-aggregate types. - Otherwise we unnecessarily pin values to the stack and currently end up triggering a backend bug in one case. - This loose cooperation with LLVM to implement the ABI is pretty ugly. - <rdar://problem/6918722> [irgen] clang miscompile of many pointer varargs on x86-64 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72419 91177308-0d34-0410-b5e6-96231b3b80d8

evaluated first. This can also improve codegen just a bit as we might have another register to play with for the evaluation of the rhs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72226 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-20This patch provides preliminary support for non-fragile instance variables ↵Fariborz Jahanian
on the GNU runtime. It currently requires a patches to GNU libobjc (and so is not enabled by default) which are currently being tested and reviewed by GNUstep before being pushed upstream. This patch does not allow support for synthesized ivars, but does provide the infrastructure needed for supporting them.
