[PATCH] [PATCH] Fix for http://llvm.org/bugs/show_bug.cgi?id=19905

[Vadim Chugunov]

Looking at the llc output you provided in the bug, I notice that it spilled and emitted CFI info for XMM registers.  What target was that compiled for?   AFAIK, only Windows 64 ABI specifies XMMs as callee-saved.   So if it was for Win64, my patch would directly address your problem.
