From: "cvs-commit at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/99037] Invalid representation of vector zero in aarch64-simd.md Date: Mon, 29 Mar 2021 10:55:11 +0000 [thread overview] Message-ID: <bug-99037-4-x35iFbxYBl@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-99037-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99037 --- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Kyrylo Tkachov <ktkachov@gcc.gnu.org>: https://gcc.gnu.org/g:37d9074e12082132ae62c12fbe958c697f638c0a commit r11-7888-g37d9074e12082132ae62c12fbe958c697f638c0a Author: Kyrylo Tkachov <kyrylo.tkachov@arm.com> Date: Mon Mar 29 11:52:24 2021 +0100 aarch64: PR target/99037 Fix RTL represntation in move_lo_quad patterns This patch fixes the RTL representation of the move_lo_quad patterns to use aarch64_simd_or_scalar_imm_zero for the zero part rather than a vec_duplicate of zero or a const_int 0. The expander that generates them is also adjusted so that we use and match the correct const_vector forms throughout. Co-Authored-By: Jakub Jelinek <jakub@redhat.com> gcc/ChangeLog: PR target/99037 * config/aarch64/aarch64-simd.md (move_lo_quad_internal_<mode>): Use aarch64_simd_or_scalar_imm_zero to match zeroes. Remove pattern matching const_int 0. (move_lo_quad_internal_be_<mode>): Likewise. (move_lo_quad_<mode>): Update for the above. * config/aarch64/iterators.md (VQ_2E): Delete. gcc/testsuite/ChangeLog: PR target/99808 * gcc.target/aarch64/pr99808.c: New test.
