--- Comment #25 from Uroš Bizjak <ubizjak at gmail dot com> ---
Let's keep this patch to gcc-14+. The compiler now sanitizes every partial
vector input to potentially trapping instructions. OTOH, the patch introduced
noticeable runtime regression, so in a follow-up patch (PR110832)
-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+.
