--- Comment #15 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Iain Buclaw <ibuc...@gcc.gnu.org>: https://gcc.gnu.org/g:f2eeda5652438fe783d4e3878139481a1b8606b6 commit r13-7496-gf2eeda5652438fe783d4e3878139481a1b8606b6 Author: Iain Buclaw <ibuc...@gdcproject.org> Date: Wed Jun 28 18:30:31 2023 +0200 d: Fix wrong code-gen when returning structs by value. Since r13-1104, structs have have compute_record_mode called too early on them, causing them to return differently depending on the order that types are generated in, and whether there are forward references. This patch moves the call to compute_record_mode into its own function, and calls it after all fields have been given a size. PR d/106977 PR target/110406 gcc/d/ChangeLog: * types.cc (finish_aggregate_mode): New function. (finish_incomplete_fields): Call finish_aggregate_mode. (finish_aggregate_type): Replace call to compute_record_mode with finish_aggregate_mode. gcc/testsuite/ChangeLog: * gdc.dg/torture/pr110406.d: New test.
