OpenMP: Accept argument to depobj's destroy clause Since OpenMP 5.2, the destroy clause takes an depend argument as argument; for the depobj directive, it the new argument is optional but, if present, it must be identical to the directive's argument. gcc/c/ChangeLog: * c-parser.cc (c_parser_omp_depobj): Accept optionally an argument to the destroy clause. gcc/cp/ChangeLog: * parser.cc (cp_parser_omp_depobj): Accept optionally an argument to the destroy clause. gcc/fortran/ChangeLog: * openmp.cc (gfc_match_omp_depobj): Accept optionally an argument to the destroy clause. libgomp/ChangeLog: * libgomp.texi (5.2 Impl.
