--- Comment #9 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:3753ceff562d8614a94a164b312f389812bd6cd8 commit r10-9641-g3753ceff562d8614a94a164b312f389812bd6cd8 Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Mar 31 10:46:01 2021 +0200 aarch64: Fix up *add<mode>3_poly_1 [PR99813] As mentioned in the PR, Uai constraint stands for aarch64_sve_scalar_inc_dec_immediate while Uav for aarch64_sve_addvl_addpl_immediate. Both *add<mode>3_aarch64 and *add<mode>3_poly_1 patterns use * return aarch64_output_sve_scalar_inc_dec (operands[2]); * return aarch64_output_sve_addvl_addpl (operands[2]); in that order, but the former with Uai,Uav order, while the latter with Uav,Uai instead. This patch swaps the constraints so that they match the output.
