--- Comment #17 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:222dbebefbbc07f78e51d82ba605988ef57e5fc9 commit r12-6162-g222dbebefbbc07f78e51d82ba605988ef57e5fc9 Author: Jakub Jelinek <ja...@redhat.com> Date: Sat Jan 1 06:29:36 2022 +0100 objc: Fix handling of break stmt inside of switch inside of ObjC foreach [PR103639] The r11-3302-g3696a50beeb73f changes broke the following ObjC testcase. in_statement is either 0 (not in a looping statement), various IN_* flags for various kinds of looping statements (or OpenMP structured blocks) or those flags ored with IN_SWITCH_STMT when a switch appears inside of those contexts. This is because break binds to switch in that last case, but continue binds to the looping construct in that case. The c_finish_bc_stmt function performs diagnostics on incorrect break/continue uses and then checks if in_statement & IN_OBJC_FOREACH and in that case jumps to the label provided by the caller, otherwise emits a BREAK_STMT or CONTINUE_STMT. This is incorrect if we have ObjC foreach with switch nested in it and break inside of that, in_statement in that case is IN_OBJC_FOREACH | IN_SWITCH_STMT and is_break is true. We want to handle it like other breaks inside of switch, i.e. emit a BREAK_STMT. The following patch fixes that. 2022-01-01 Jakub Jelinek <ja...@redhat.com> PR objc/103639 * c-typeck.c (c_finish_bc_stmt): For break inside of switch inside of ObjC foreach, emit normal BREAK_STMT rather than goto to label. 2022-01-01 Iain Sandoe <i...@sandoe.co.uk> PR objc/103639 * objc.dg/pr103639.m: New test.
