[llvm-commits] [PATCH] optimization of (x & y) | (x ^ y), (x & y) + (x ^ y)

[Manman Ren]

This patch is intended to reduce both (x & y) | (x ^ y) and (x & y) + (x ^y) to bitwise or.
It  modified two source files: lib/Transforms/InstCombine/InstCombineAndOrXor.cpp and lib/Transforms/InstCombine/InstCombineAddSub.cpp.
A test case is also included in the patch.

Please review & provide feedback.

Thanks,
