Chris Lattner	d2b1fb27df	copy mmx values from/to memory with GPRs on x86-32 instead of with mmx registers. This horribleness is apparently done by gcc to avoid having to insert emms in places that really should have it. This is the second half of rdar://5741668. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47474 91177308-0d34-0410-b5e6-96231b3b80d8	2008-02-22 05:18:04 +00:00
Chris Lattner	149a4e56fc	Start using GPR's to copy around mmx value instead of mmx regs. GCC apparently does this, and code depends on not having to do emms when this happens. This is x86-64 only so far, second half should handle x86-32. rdar://5741668 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47470 91177308-0d34-0410-b5e6-96231b3b80d8	2008-02-22 02:09:43 +00:00
