This allows us to optimize test12 into: define i32 @test12(i32 %X) { %factor = mul i32 %X, -3 ; <i32> [#uses=1] %Z = add i32 %factor, 6 ; <i32> [#uses=1] ret i32 %Z } instead of: define i32 @test12(i32 %X) { %Y = sub i32 6, %X ; <i32> [#uses=1] %C = sub i32 %Y, %X ; <i32> [#uses=1] %Z = sub i32 %C, %X ; <i32> [#uses=1] ret i32 %Z } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92373 91177308-0d34-0410-b5e6-96231b3b80d8		2009-12-31 20:34:32 +00:00
