on powerpc-linux (or powerpc64-linux biarch -m32).
signbit-1.c is quite obviously a 64-bit only testcase given the
scan-assembler directives, and the purpose of the testcase to verify
the 64-bit only UNSPEC_SIGNBIT patterns. It could be made to pass for
-m32 by adding -mpowerpc64, but that option that isn't very effective
when bi-arch testing and results in errors on rs6000-aix. And it is
pointless to match -m32 stores to the stack followed by loads, which
is what we do at the moment.
signbit-2.c on the other hand has more reasonable 32-bit output.
Regression tested powerpc64-linux biarch.
* gcc.target/powerpc/signbit-1.c: Reinstate lp64 condition.
* gcc.target/powerpc/signbit-2.c: Match 32-bit output too.
