* | Introduce a pass to insert vzeroupper instructions to avoid AVX to | Bruno Cardoso Lopes | 2011-08-23 | 1 | -0/+105 |
SSE transition penalty. The pass is enabled through the "x86-use-vzeroupper" llc command line option.

Comments and ideas now and in further commits will be very appreciated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138317 91177308-0d34-0410-b5e6-96231b3b80d8 |
