--- Comment #9 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Kyrylo Tkachov <ktkac...@gcc.gnu.org>: https://gcc.gnu.org/g:ff825b8158394a01a43359efd91d0b6b8c4fa21b commit r10-7512-gff825b8158394a01a43359efd91d0b6b8c4fa21b Author: Srinath Parvathaneni <srinath.parvathan...@arm.com> Date: Thu Apr 2 10:23:47 2020 +0100 [ARM]: Fix for MVE ACLE intrinsics with writeback (PR94317). Following MVE ACLE intrinsics have an issue with writeback to the base address. vldrdq_gather_base_wb_s64, vldrdq_gather_base_wb_u64, vldrdq_gather_base_wb_z_s64, vldrdq_gather_base_wb_z_u64, vldrwq_gather_base_wb_s32, vldrwq_gather_base_wb_u32, vldrwq_gather_base_wb_z_s32, vldrwq_gather_base_wb_z_u32, vldrwq_gather_base_wb_f32, vldrwq_gather_base_wb_z_f32. This patch fixes the bug reported in PR94317 by adding separate builtin calls to update the result and writeback to base address for the above intrinsics. 2020-04-02 Srinath Parvathaneni <srinath.parvathan...@arm.com> PR target/94317 * config/arm/arm-builtins.c (LDRGBWBXU_QUALIFIERS): Define.
