--- Comment #12 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Andrew Pinski <pins...@gcc.gnu.org>: https://gcc.gnu.org/g:af974df94751195ce72e86d7b88e5d5444375b45 commit r15-5803-gaf974df94751195ce72e86d7b88e5d5444375b45 Author: Andrew Pinski <quic_apin...@quicinc.com> Date: Tue Nov 19 00:19:57 2024 -0800 aarch64: Mark __builtin_aarch64_im_lane_boundsi as leaf and nothrow [PR117665] __builtin_aarch64_im_lane_boundsi is known not to throw or call back into another function since it will either folded into an NOP or will produce a compiler error. This fixes the ICE by fixing the missed optimization. It does not fix the underlying issue with fold_marked_statements; which I filed as PR 117668. Built and tested for aarch64-linux-gnu. PR target/117665 gcc/ChangeLog: * config/aarch64/aarch64-builtins.cc (aarch64_init_simd_builtin_functions): Pass nothrow and leaf as attributes to aarch64_general_add_builtin for __builtin_aarch64_im_lane_boundsi. gcc/testsuite/ChangeLog: * g++.target/aarch64/lane-bound-1.C: New test. * gcc.target/aarch64/lane-bound-3.c: New test.
