    i386: Wrong code with __builtin_parityl [PR112672]

    gen_parityhi2_cmp instruction clobbers its input operand, so use
    a temporary register in the call to gen_parityhi2_cmp.

            PR target/112672

    gcc/ChangeLog:

            * config/i386/i386.md (parityhi2):
            Use temporary register in the call to gen_parityhi2_cmp.

    gcc/testsuite/ChangeLog:

            * gcc.target/i386/pr112672.c: New test.
