LLVM backend for 6502
This is already done for shifts. Allow it for rotations as well. E.g.: (rotl:i32 x, (trunc (and y, 31))) -> (rotl:i32 x, (and (trunc y), 31)) Use the newly factored-out distributeTruncateThroughAnd. With this patch and some X86.td tweaks we should be able to remove redundant masking of the rotation amount like in the example above. HW implicitly performs this masking. The testcase will be added as part of the X86 patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203316 91177308-0d34-0410-b5e6-96231b3b80d8 |
