Chris Lattner b3ddfc42af add two dag combines: ... (C1-X) == C2 --> X == C1-C2 (X+C1) == C2 --> X == C2-C1 This allows us to compile this: bool %X(int %X) { %Y = add int %X, 14 %Z = setne int %Y, 12345 ret bool %Z } into this: _X: cmpl $12331, 4(%esp) setne %al movzbl %al, %eax andl $1, %eax ret not this: _X: movl $14, %eax addl 4(%esp), %eax cmpl $12345, %eax setne %al movzbl %al, %eax andl $1, %eax ret Testcase here: Regression/CodeGen/X86/compare-add.ll nukage of the and coming up next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25898 91177308-0d34-0410-b5e6-96231b3b80d8		2006-02-02 06:36:13 +00:00
