--- Comment #6 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Tobias Burnus <bur...@gcc.gnu.org>: https://gcc.gnu.org/g:2fcccf21a34f92ea060b492c9b2aecb56cd5d167 commit r15-3413-g2fcccf21a34f92ea060b492c9b2aecb56cd5d167 Author: Tobias Burnus <tbur...@baylibre.com> Date: Tue Sep 3 12:02:23 2024 +0200 LTO/WPA: Ensure that output_offload_tables only writes table once [PR116535] When ltrans was written concurrently, e.g. via -flto=N (N > 1, assuming sufficient partiations, e.g., via -flto-partition=max), output_offload_tables wrote the output tables once per fork. PR lto/116535 gcc/ChangeLog: * lto-cgraph.cc (output_offload_tables): Remove offload_ frees. * lto-streamer-out.cc (lto_output): Make call to it depend on lto_get_out_decl_state ()->output_offload_tables_p. * lto-streamer.h (struct lto_out_decl_state): Add output_offload_tables_p field. * tree-pass.h (ipa_write_optimization_summaries): Add bool argument. * passes.cc (ipa_write_summaries_1): Add bool output_offload_tables_p arg. (ipa_write_summaries): Update call. (ipa_write_optimization_summaries): Accept output_offload_tables_p. gcc/lto/ChangeLog: * lto.cc (stream_out): Update call to ipa_write_optimization_summaries to pass true for first partition.
