--- Comment #9 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Kyrylo Tkachov <ktkac...@gcc.gnu.org>: https://gcc.gnu.org/g:1a92899b08e61d503a2897f2f66b064eb84706bc commit r10-9628-g1a92899b08e61d503a2897f2f66b064eb84706bc Author: Kyrylo Tkachov <kyrylo.tkac...@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 <ja...@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.
