--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Andrew Pinski <pins...@gcc.gnu.org>: https://gcc.gnu.org/g:d8bc31d973d2ab3fabb5e85e7c4354ffb2283512 commit r15-3437-gd8bc31d973d2ab3fabb5e85e7c4354ffb2283512 Author: Andrew Pinski <quic_apin...@quicinc.com> Date: Tue Sep 3 17:10:37 2024 -0700 aarch64: Fix testcase vec-init-22-speed.c [PR116589] For this testcase, the trunk produces: ``` f_s16: fmov s31, w0 fmov s0, w1 ``` While the testcase was expecting what was produced in GCC 14: ``` f_s16: sxth w0, w0 sxth w1, w1 fmov d31, x0 fmov d0, x1 ``` After r15-1575-gea8061f46a30 the code was: ``` dup v31.4h, w0 dup v0.4h, w1 ``` But when ext-dce was added with r15-1901-g98914f9eba5f19, we get the better code generation now and only fmov's. Pushed as obvious after running the testcase. PR target/116589 gcc/testsuite/ChangeLog: * gcc.target/aarch64/vec-init-22-speed.c: Update scan for better code gen.
