This test was failing on X86 machines which do not have SSE4. Fixed the test by specifying that the target CPU is corei7. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133053 91177308-0d34-0410-b5e6-96231b3b80d8 2011-06-15 12:26:53 +00:00			`; A test for checking PR 9623`

Fix two-address pass's aggressive instruction commuting heuristics. It's meant to catch cases like: %reg1024<def> = MOV r1 %reg1025<def> = MOV r0 %reg1026<def> = ADD %reg1024, %reg1025 r0 = MOV %reg1026 By commuting ADD, it let coalescer eliminate all of the copies. However, there was a bug in the heuristics where it ended up commuting the ADD in: %reg1024<def> = MOV r0 %reg1025<def> = MOV 0 %reg1026<def> = ADD %reg1024, %reg1025 r0 = MOV %reg1026 That did no benefit but rather ensure the last MOV would not be coalesced. rdar://11355268 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156048 91177308-0d34-0410-b5e6-96231b3b80d8 2012-05-03 01:45:13 +00:00			`; CHECK: ret`
