From: "cvs-commit at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug preprocessor/114007] gcc chokes on __has_cpp_attribute(clang::unsafe_buffer_usage) Date: Sat, 02 Mar 2024 00:39:05 +0000 [thread overview] Message-ID: <bug-114007-4-QbcUVcXUec@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-114007-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114007 --- Comment #29 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Jakub Jelinek <jakub@gcc.gnu.org>: https://gcc.gnu.org/g:051cd2a3ee9ba9f47d640a10e96c79b6c5124736 commit r13-8392-g051cd2a3ee9ba9f47d640a10e96c79b6c5124736 Author: Jakub Jelinek <jakub@redhat.com> Date: Thu Feb 22 19:32:02 2024 +0100 c: Handle scoped attributes in __has*attribute and scoped attribute parsing changes in -std=c11 etc. modes [PR114007] We aren't able to parse __has_attribute (vendor::attr) (and __has_c_attribute and __has_cpp_attribute) in strict C < C23 modes. While in -std=gnu* modes or in -std=c23 there is CPP_SCOPE token, in -std=c* (except for -std=c23) there are is just a pair of CPP_COLON tokens. The c-lex.cc hunk adds support for that, but always returns 0 in that case unlike the GCC 14+ version. 2024-02-22 Jakub Jelinek <jakub@redhat.com> PR c/114007 gcc/c-family/ * c-lex.cc (c_common_has_attribute): Parse 2 CPP_COLONs with the first one with COLON_SCOPE flag the same as CPP_SCOPE but ensure 0 is returned then. gcc/testsuite/ * gcc.dg/c23-attr-syntax-8.c: New test. libcpp/ * include/cpplib.h (COLON_SCOPE): Define to PURE_ZERO. * lex.cc (_cpp_lex_direct): When lexing CPP_COLON with another colon after it, if !CPP_OPTION (pfile, scope) set COLON_SCOPE flag on the first CPP_COLON token.
