--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Sandiford <rsand...@gcc.gnu.org>: https://gcc.gnu.org/g:73c3dacef9a30d7d66918606a97c496c71289f1b commit r12-5998-g73c3dacef9a30d7d66918606a97c496c71289f1b Author: Richard Sandiford <richard.sandif...@arm.com> Date: Wed Dec 15 12:19:00 2021 +0000 aarch64: Don't classify vector pairs as short vectors [PR103094] In this PR we were wrongly classifying a pair of 8-byte vectors as a 16-byte âshort vectorâ (in the AAPCS64 sense). As the comment in the patch says, this stems from an old condition in aarch64_short_vector_p that is too loose, but that would be difficult to tighten now. We can still do the right thing for the newly-added modes though, since there are no backwards compatibility concerns there. Co-authored-by: Tamar Christina <tamar.christ...@arm.com> gcc/ PR target/103094 * config/aarch64/aarch64.c (aarch64_short_vector_p): Return false for structure modes, rather than ignoring the type in that case. gcc/testsuite/ PR target/103094 * gcc.target/aarch64/pr103094.c: New test.
