Its C FE counterpart was already implemented in r11-4813. In cp_parser_statement I rely on in_compound to determine whether we're in a compound-statement, so that the patch doesn't accidentally allow void fn(int c) { if (c) label: } Strangely, in_compound was reset after seeing a label (this is tested in c-c++-common/gomp/pr63326.c), so I've made a modifiable copy specific for OpenMP #pragma purposes. PR c++/103539 gcc/cp/ChangeLog: * parser.cc (cp_parser_statement): Constify the in_compound parameter. Create a modifiable copy. Allow labels at the end of compound statements. gcc/testsuite/ChangeLog: * g++.dg/cpp23/label1.C: New test. * g++.dg/cpp23/label2.C: New test. ^ permalink raw reply [flat|nested] 4+ messages in thread
