Note that the patch only changes something for WORD_REGISTER_OPERATIONS targets though, so you can exclude h8300, i386, powerpc64, s390 and x86_64. Can you easily re-do the test with the reversion of the nonzero_bits1 change, i.e. the patch that you had/have in your tree? > The alpha one looks really bad. Only the powerpc64 is a win. See above, this must be something else.
