Evan Cheng e721f5c8d3 Improve codegen for select's: ... if (x != 0) x = 1 if (x == 1) x = 1 Previous codegen looks like this: mov r1, r0 cmp r1, #1 mov r0, #0 moveq r0, #1 The naive lowering select between two different values. It should recognize the test is equality test so it's more a conditional move rather than a select: cmp r0, #1 movne r0, #0 rdar://9758317 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135017 91177308-0d34-0410-b5e6-96231b3b80d8		2011-07-13 00:42:17 +00:00
