--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
Even though the generated code has changed, this is still a problem with 6.0
and in all supported versions prior to it as noted in bug 65010, for both
powerpc64 and powerpc64le, where GCC emits:

f:
        addi 3,3,1
        extsw 3,3
        blr

g:
        addi 3,3,1
        extsw 3,3
        b f
