Duncan P. N. Exon Smith	7c29644cce	Setting the CPU in the new vaargs test ... Trying to fix buildbots after r197503 (test passes locally). <rdar://problem/15627766> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197505 91177308-0d34-0410-b5e6-96231b3b80d8	2013-12-17 16:20:37 +00:00
Duncan P. N. Exon Smith	c69e3920dd	Revert "Revert "Mark vastart_save_xmm_regs as changing EFLAGS"" ... This reverts commit r197481, recommiting r197469 with an extra fix. The vastart_save_xmm_regs pseudo-instruction expands to a test and a branch, so it modifies EFLAGS. Mark it so, or else the scheduler might place it in the middle of another test+branch. This fixes a bug exposed by r192750, which changed the initial scheduler to source-order as part of enabling the MI Scheduler for X86. This re-commit changes the VASTART_SAVE_XMM_REGS custom inserter not to try to save %flags, and adds a test that catches the bad behavior of r197469. <rdar://problem/15627766> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197503 91177308-0d34-0410-b5e6-96231b3b80d8	2013-12-17 15:54:45 +00:00
