--- Comment #1 from Manjunath S Matti <mmatti.gnu at gmail dot com> --- Add the int128 effective-target requirement, as the other __int128 tests in gcc.target/powerpc (e.g. builtins-msum-runnable.c, p10-vdivq-vmodq.c, p10_vec_xl_sext.c) already do. The test then becomes UNSUPPORTED for -m32 and is unchanged for -m64 on both endiannesses.
