| * | Passing AVX 256-bit structures in Win64 was wrong. | Elena Demikhovsky | 2012-02-01 |

| * | Handle call-clobbered ymm registers on Win64. | Jakob Stoklund Olesen | 2012-01-26 |
| 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 | |||
