Moving these patterns from TableGen files to PerformDAGCombine() should allow us to generate better code by eliminating unnecessary shifts and extensions earlier. This also fixes a bug where the MAD pattern was calling SimplifyDemandedBits with a 24-bit mask on the first operand even when the full pattern wasn't being matched. This occasionally resulted in some instructions being incorrectly deleted from the program. v2: - Fix bug with 64-bit mul git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205731 91177308-0d34-0410-b5e6-96231b3b80d8 |
