--- Comment #13 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Senthil Kumar Selvaraj <[email protected]>: https://gcc.gnu.org/g:3090d28ab359e8299aee33386dc44b81faf8edca commit r16-7117-g3090d28ab359e8299aee33386dc44b81faf8edca Author: Senthil Kumar Selvaraj <[email protected]> Date: Wed Jan 28 13:59:55 2026 +0530 c: Fix parser error on address space names [PR 123583] This patch fixes a regression introduced by PR 67784 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67784) - it broke recognition of named address space qualifiers (such as __memx on AVR or __seg_gs on x86) after certain statements. The fix for PR 67784 attempts to reclassify tokens whose token->id_kind could have been set incorrectly (because of possibly wrong scope when peeking ahead). c_parser_maybe_reclassify_token only skips reclassification for C_ID_CLASSNAME though - a token with id_kind = C_ID_ADDRSPACE ends up getting reclassified as C_ID_ID, eventually causing a ": error: '<address space name>' undeclared" error later down the line. Rather than explicitly excluding C_ID_ADDRSPACE, the patch modifies the check to reclassify only tokens kinds that could potentially get incorrectly classified - C_ID_ID and C_ID_TYPENAME. Bootstrapped and regtested on x86_64-linux.
