Bill Wendling 7d9f2b93a3 This test case: ... long test(long x) { return (x & 123124) | 3; } Currently compiles to: _test: orl $3, %edi movq %rdi, %rax andq $123127, %rax ret This is because instruction and DAG combiners canonicalize (or (and x, C), D) -> (and (or, D), (C | D)) However, this is only profitable if (C & D) != 0. It gets in the way of the 3-addressification because the input bits are known to be zero. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97616 91177308-0d34-0410-b5e6-96231b3b80d8		2010-03-03 00:35:56 +00:00
