Chris Lattner e576b91948 Implement select.ll:test12* ... This transforms code like this: %C = or %A, %B %D = select %cond, %C, %A into: %C = select %cond, %B, 0 %D = or %A, %C Since B is often a constant, the select can often be eliminated. In any case, this reduces the usage count of A, allowing subsequent optimizations to happen. This xform applies when the operator is any of: add, sub, mul, or, xor, and, shl, shr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12800 91177308-0d34-0410-b5e6-96231b3b80d8		2004-04-09 23:46:01 +00:00
