mingmingl added a comment.

For the affected test case `test_nonuseful_bits`, one BFM and one ORR is generated now (https://godbolt.org/z/a3c68f7dE) with this commit <https://github.com/llvm/llvm-project/commit/f62d8a1a5044df7b8d72033d056375b4ab256012>. Going to abandon this patch (rather than rebase it for other BFI improvements). Thanks for the discussions around BFM/ORR.
