Michael Liao 239ffb30b0 Enhance the fix of PR17631 ... - The fix to PR17631 fixes part of the cases where 'vzeroupper' should not be issued before 'call' insn. There're other cases where helper calls will be inserted not limited to epilog. These helper calls do not follow the standard calling convention and won't clobber any YMM registers. (So far, all call conventions will clobber any or part of YMM registers.) This patch enhances the previous fix to cover more cases 'vzerosupper' should not be inserted by checking if that function call won't clobber any YMM registers and skipping it if so. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196261 91177308-0d34-0410-b5e6-96231b3b80d8		2013-12-03 09:17:32 +00:00
