Bruno Cardoso Lopes 3bde6fe0df Introduce a pass to insert vzeroupper instructions to avoid AVX to ... SSE transition penalty. The pass is enabled through the "x86-use-vzeroupper" llc command line option. This is only the first step (very naive and conservative one) to sketch out the idea, but proper DFA is coming next to allow smarter decisions. 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		2011-08-23 01:14:17 +00:00
