--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Iain Buclaw <ibuc...@gcc.gnu.org>: https://gcc.gnu.org/g:06b794846f1d8fa55133a257f6d7af39398b9cdc commit r10-9901-g06b794846f1d8fa55133a257f6d7af39398b9cdc Author: Iain Buclaw <ibuc...@gdcproject.org> Date: Thu Jun 10 19:59:23 2021 +0200 d: Fix ICE in TypeInfoDeclaration, at dmd/declaration.c (PR100967) Generate a stub TypeInfo class even if the root Object class is missing. The front-end will take care of issuing an error and abort the compilation when running semantic on constructed TypeInfo objects. The errors issued by the code generation pass relating to missing or disabled RTTI has been consolidated into a single function, so that a meaningful error will be emitted before the front-end terminates. gcc/d/ChangeLog: PR d/100967 * d-frontend.cc (getTypeInfoType): Move TypeInfo checks to check_typeinfo_type and call new function. * d-tree.h (check_typeinfo_type): Declare. * typeinfo.cc: Include dmd/scope.h. (create_frontend_tinfo_types): Generate front-end types even if Object is missing. (build_typeinfo): Move TypeInfo checks to check_typeinfo_type and call new function. (check_typeinfo_type): New function. gcc/testsuite/ChangeLog: PR d/100967 * gdc.dg/pr100967.d: New test. (cherry picked from commit 5ae4a73057dd26e7f09b5ba5190b84b1bbea4368)
