Hal Finkel 958b670c34 [PowerPC] Add support for the CMPB instruction ... Newer POWER cores, and the A2, support the cmpb instruction. This instruction compares its operands, treating each of the 8 bytes in the GPRs separately, returning a 'mask' result of 0 (for false) or -1 (for true) in each byte. Code generation support is added, in the form of a PPCISelDAGToDAG DAG-preprocessing routine, that recognizes patterns close to what the instruction computes (either exactly, or related by a constant masking operation), and generates the cmpb instruction (along with any necessary constant masking operation). This can be expanded if use cases arise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225106 91177308-0d34-0410-b5e6-96231b3b80d8		2015-01-03 01:16:37 +00:00
