What needs handling incrementally is diagnose mismatching begin/end pair like [[omp::directive (declare target)]]; int a; #pragma omp end declare target or #pragma omp declare target int b; [[omp::directive (end declare target)]]; and handling declare simd/declare variant on declarations (function definitions and declarations), for those in two different spots. 2021-07-31 Jakub Jelinek * parser.c (cp_parser_declaration): Handle OpenMP directives in attribute-declaration. * g++.dg/gomp/attrs-9.C: New test.
