--- Comment #45 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-8 branch has been updated by Kyrylo Tkachov <ktkac...@gcc.gnu.org>: https://gcc.gnu.org/g:1788d74b05b7936e9e8dd01a8f66701ad2bc2951 commit r8-10536-g1788d74b05b7936e9e8dd01a8f66701ad2bc2951 Author: Tamar Christina <tamar.christ...@arm.com> Date: Thu Jan 10 03:30:59 2019 +0000 AArch64: Implement Armv8.3-a complex arithmetic intrinsics I'd like to backport some patches from Tamar in GCC 9 to GCC 8 that implement the complex arithmetic intrinsics for Advanced SIMD. These should have been present in GCC 8 that gained support for Armv8.3-a. There were 4 follow-up fixes that I've rolled into the one commit. Bootstrapped and tested on aarch64-none-linux-gnu and arm-none-linux-gnueabihf on the GCC 8 branch. gcc/ PR target/71233 * config/aarch64/aarch64-builtins.c (enum aarch64_type_qualifiers): Add qualifier_lane_pair_index.
