This is just a testsuite issue. The functions are currently marked as noinline.
 You can either add -fno-ipa-vrp or mark them with noipa instead. I am not sure
if noipa here is right due to having some ipa happening due to localization.

Thanks for looking into this, I just tested with noipa and confirmed it worked
well.

    testsuite, rs6000: Adjust pcrel-sibcall-1.c with noipa [PR112751]

    As PR112751 shows, commit r14-5628 caused pcrel-sibcall-1.c
    to fail as it enables ipa-vrp which makes return values of
    functions {x,y,xx} as known and propagated.  This patch is
    to adjust it with noipa to make it not fragile.

            * gcc.target/powerpc/pcrel-sibcall-1.c: Replace noinline as noipa.
