This patch introduces the OMP_DISPATCH tree node, as well as two new clauses
`nocontext` and `novariants`. It defines/exposes interfaces that will be
used in subsequent patches that add front-end and middle-end support, but
nothing generates these nodes yet.
gcc/ChangeLog:
* builtin-types.def (BT_FN_PTR_CONST_PTR_INT): New.
* omp-selectors.h (enum omp_ts_code): Add OMP_TRAIT_CONSTRUCT_DISPATCH.
* tree-core.h (enum omp_clause_code): Add OMP_CLAUSE_NOVARIANTS and
OMP_CLAUSE_NOCONTEXT.
* tree-pretty-print.cc (dump_omp_clause): Handle OMP_CLAUSE_NOVARIANTS
and OMP_CLAUSE_NOCONTEXT.
(dump_generic_node): Handle OMP_DISPATCH.
* tree.cc (omp_clause_num_ops): Add OMP_CLAUSE_NOVARIANTS and
OMP_CLAUSE_NOCONTEXT.
(omp_clause_code_name): Add "novariants" and "nocontext".
* tree.def (OMP_DISPATCH): New.
* tree.h (OMP_DISPATCH_BODY): New macro.
(OMP_DISPATCH_CLAUSES): New macro.
(OMP_CLAUSE_NOVARIANTS_EXPR): New macro.
(OMP_CLAUSE_NOCONTEXT_EXPR): New macro.
gcc/fortran/ChangeLog:
* types.def (BT_FN_PTR_CONST_PTR_INT): Declare.
