Hi, This patch changes the definition of TARGET_MADDLD and includes TARGET_POWERPC64, since maddld is a 64 bit instruction.
maddld-1.c now checks "has_arch_ppc64". It depends on a patch which fixes empty TU problem. https://gcc.gnu.org/pipermail/gcc-patches/2022-July/598744.html Bootstrapped and tested on powerpc64-linux BE and LE with no regressions. Is this okay for trunk? Any recommendations? Thanks a lot.
