Chris Lattner 2ad913b342 Disable the (A == (B-A)) -> 2*A == B xform when the sub has multiple uses (in ... this case, the xform introduces an extra operation). This compiles PowerPC/compare-duplicate.ll into: _test: subf r2, r3, r4 cmplw cr0, r2, r3 bne cr0, LBB1_2 ;F instead of: _test: slwi r2, r3, 1 subf r3, r3, r4 cmplw cr0, r4, r2 bne cr0, LBB1_2 ;F This is target independent of course. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37246 91177308-0d34-0410-b5e6-96231b3b80d8		2007-05-19 00:43:44 +00:00
