I am not sure how to handle it best. This reminds me I've left the C/C++ FE diagnostics about mixing link and to/enter on the same variable in separate directives as is, so it always talked about mixing link and to clauses. This patch adjusts it, so that if link is first, it talks about the clause actually used and if link is later, uses to or enter together in the wording. 2022-05-28 Jakub Jelinek gcc/c/ * c-parser.cc (c_parser_omp_declare_target): If OMP_CLAUSE_LINK was seen first, use "%" or "%" depending on OMP_CLAUSE_ENTER_TO of the current clause, otherwise use "% or %" wording. gcc/cp/ * parser.cc (handle_omp_declare_target_clause): If OMP_CLAUSE_LINK was seen first, use "%" or "%" depending on OMP_CLAUSE_ENTER_TO of the current clause, otherwise use "% or %" wording. gcc/testsuite/ * c-c++-common/gomp/declare-target-2.c: Add further tests for mixing of link and to/enter clauses on separate directives. --- gcc/c/c-parser.cc | 11 ++++++++--- gcc/cp/parser.cc | 11 ++++++++--- .../c-c++-common/gomp/declare-target-2.c | 17 ++++++++++++++++- 3 files changed, 32 insertions(+), 7 deletions(-) diff --git a/gcc/c/c-parser.cc b/gcc/c/c-parser.cc index 678d91415a9..7cc4d93cf87 100644 --- a/gcc/c/c-parser.cc +++ b/gcc/c/c-parser.cc @@ -22067,9 +22067,14 @@ c_parser_omp_declare_target (c_parser *parser) id = get_identifier ("omp declare target"); if (at2) { - error_at (OMP_CLAUSE_LOCATION (c), - "%qD specified both in declare target % and %" - " clauses", t); + if (OMP_CLAUSE_CODE (c) == OMP_CLAUSE_ENTER) + error_at (OMP_CLAUSE_LOCATION (c), + "%qD specified both in declare target % and %qs" + " clauses", t, OMP_CLAUSE_ENTER_TO (c) ?
