Linux since version 3.4 and GCC since version 4.7 support X32 ABI.

LLVM could also support it.

An initial X32 patch at http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-June/050360.html and re-posted with split patches.

Any chance of getting this fixed? Still seeing this on LLVM trunk, and it makes
me sad:

could you post the test case? C source or LLVM IR?
