Dan Gohman c093f48834 Teach IVUsers to stop at non-affine expressions unless they are both ... outside the loop and reducible. This more completely hides them from LSR, which isn't usually able to do anything meaningful with non-affine expressions anyway, and this consequently hides them from SCEVExpander, which is acutely unprepared for non-affine expressions. Replace test/CodeGen/X86/lsr-nonaffine.ll with a new test that tests the new behavior. This works around the bug in PR10117 / rdar://problem/9633149, and is generally an improvement besides. llvm-svn: 134268		2011-07-01 22:05:19 +00:00
