--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:5c3ab44771d0524140cf2ce5de594fcf7fefcd6f commit r12-10044-g5c3ab44771d0524140cf2ce5de594fcf7fefcd6f Author: Richard Biener <rguent...@suse.de> Date: Mon Aug 21 10:34:30 2023 +0200 debug/111080 - avoid outputting debug info for unused restrict qualified type The following applies some maintainance with respect to type qualifiers and kinds added by later DWARF standards to prune_unused_types_walk. The particular case in the bug is not handling (thus marking required) all restrict qualified type DIEs. I've found more DW_TAG_*_type that are unhandled, looked up the DWARF docs and added them as well based on common sense. PR debug/111080 * dwarf2out.cc (prune_unused_types_walk): Handle DW_TAG_restrict_type, DW_TAG_shared_type, DW_TAG_atomic_type, DW_TAG_immutable_type, DW_TAG_coarray_type, DW_TAG_unspecified_type and DW_TAG_dynamic_type as to only output them when referenced. * gcc.dg/debug/dwarf2/pr111080.c: New testcase.
