--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:083e8e66d2e90992fa83a53bfc3553dfa91abda1 commit r12-8077-g083e8e66d2e90992fa83a53bfc3553dfa91abda1 Author: Jakub Jelinek <ja...@redhat.com> Date: Mon Apr 11 10:41:07 2022 +0200 c-family: Initialize ridpointers for __int128 etc. [PR105186] The following testcase ICEs with C++ and is incorrectly rejected with C. The reason is that both FEs use ridpointers identifiers for CPP_KEYWORD and value or u.value for CPP_NAME e.g. when parsing attributes or OpenMP directives etc., like: /* Save away the identifier that indicates which attribute this is. */ identifier = (token->type == CPP_KEYWORD) /* For keywords, use the canonical spelling, not the parsed identifier. */ ? ridpointers[(int) token->keyword] : id_token->u.value; identifier = canonicalize_attr_name (identifier); I've tried to change those to use ridpointers only if non-NULL and otherwise use the value/u.value even for CPP_KEYWORDS, but that was a large 10 hunks patch. The following patch instead just initializes ridpointers for the __intNN keywords. It can't be done earlier before we record_builtin_type as there are 2 different spellings and if we initialize those ridpointers early, the second record_builtin_type fails miserably. 2022-04-11 Jakub Jelinek <ja...@redhat.com> PR c++/105186 * c-common.cc (c_common_nodes_and_builtins): After registering __int%d and __int%d__ builtin types, initialize corresponding ridpointers entry. * c-c++-common/pr105186.c: New test.
