--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Thu Apr 20 09:18:02 2017 New Revision: 247014 URL: https://gcc.gnu.org/viewcvs?rev=247014&root=gcc&view=rev Log: PR middle-end/80423 * tree.h (build_array_type): Add typeless_storage default argument. * tree.c (type_cache_hasher::equal): Also compare TYPE_TYPELESS_STORAGE flag for ARRAY_TYPEs. (build_array_type): Add typeless_storage argument, set TYPE_TYPELESS_STORAGE to it, if shared also hash it, and pass to recursive call. (build_nonshared_array_type): Adjust build_array_type_1 caller. (build_array_type): Likewise. Add typeless_storage argument. c-family/ * c-common.c (complete_array_type): Preserve TYPE_TYPELESS_STORAGE. cp/ * tree.c (build_cplus_array_type): Call build_array_type with the intended TYPE_TYPELESS_STORAGE flag value, instead of calling build_array_type and modifying later TYPE_TYPELESS_STORAGE on the shared type. testsuite/ * g++.dg/other/pr80423.C: New test. Added: trunk/gcc/testsuite/g++.dg/other/pr80423.C Modified: trunk/gcc/ChangeLog trunk/gcc/c-family/ChangeLog trunk/gcc/c-family/c-common.c trunk/gcc/cp/ChangeLog trunk/gcc/cp/tree.c trunk/gcc/testsuite/ChangeLog trunk/gcc/tree.c trunk/gcc/tree.h
