--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Antoni Boucher <ant...@gcc.gnu.org>: https://gcc.gnu.org/g:62fa2e43cccc4b60558a7c3b4c578fda744bde96 commit r15-6070-g62fa2e43cccc4b60558a7c3b4c578fda744bde96 Author: Antoni Boucher <boua...@zoho.com> Date: Wed Dec 4 20:59:53 2024 -0500 aarch64: Fix ICE happening in SET_TYPE_VECTOR_SUBPARTS with libgccjit The structure aarch64_simd_type_info was split in 2 because we do not want to reset the static members of aarch64_simd_type_info to their default value. We only want the tree types to be GC-ed. This is necessary for libgccjit which can run multiple times in the same process. If the static values were GC-ed, the second run would ICE/segfault because of their invalid value. The following test suites passed for this patch: * The aarch64 tests. * The aarch64 regression tests. The number of failures of the jit tests on aarch64 lowered from +100 to ~7. gcc/ChangeLog: PR target/117923 * config/aarch64/aarch64-builtins.cc: Remove GTY marker on aarch64_simd_types, aarch64_simd_types_trees (new variable), rename aarch64_simd_types to aarch64_simd_types_trees. * config/aarch64/aarch64-builtins.h: Remove GTY marker on aarch64_simd_types, aarch64_simd_types_trees (new variable). * config/aarch64/aarch64-sve-builtins-shapes.cc: Rename aarch64_simd_types to aarch64_simd_types_trees. * config/aarch64/aarch64-sve-builtins.cc: Rename aarch64_simd_types to aarch64_simd_types_trees.
