--- Comment #13 from Uroš Bizjak <ubizjak at gmail dot com> ---
Let's keep this patch to gcc-14+. The runtime regression is now due to strict
IEEE compilance, where the compiler sanitizes every partial vector input to
potentially trapping instructions. OTOH, -fno-trapping-math removes
sanitization fixups (and the documentation documents possible issues with
assembler and builtins passing non-conformat FP values), and
-m[no-]partial-vector-fp-math option is introduced to completely disable
potentially traping instructions for partial vectors.
So, fixed for gcc-14+.
