Elena Demikhovsky	1766971769	Passing AVX 256-bit structures in Win64 was wrong. Fixed Win64 calling conventions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149494 91177308-0d34-0410-b5e6-96231b3b80d8	2012-02-01 10:46:14 +00:00
Jakob Stoklund Olesen	53fa56e8dc	Handle call-clobbered ymm registers on Win64. The Win64 calling convention has xmm6-15 as callee-saved while still clobbering all ymm registers. Add a YMM_HI_6_15 pseudo-register that aliases the clobbered part of the ymm registers, and mark that as call-clobbered. This allows live xmm registers across calls. This hack wouldn't be necessary with RegisterMask operands representing the call clobbers, but they are not quite operational yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149088 91177308-0d34-0410-b5e6-96231b3b80d8	2012-01-26 22:59:28 +00:00

Handle call-clobbered ymm registers on Win64.

The Win64 calling convention has xmm6-15 as callee-saved while still
clobbering all ymm registers.

Add a YMM_HI_6_15 pseudo-register that aliases the clobbered part of the
ymm registers, and mark that as call-clobbered.  This allows live xmm
registers across calls.

This hack wouldn't be necessary with RegisterMask operands representing
the call clobbers, but they are not quite operational yet.
