openmp: Fortran strictly-structured blocks support
This implements strictly-structured blocks support for Fortran, as specified in
OpenMP 5.2. This now allows using a Fortran BLOCK construct as the body of most
OpenMP constructs, with a "!$omp end ..." ending directive optional for that
form.
gcc/fortran/ChangeLog:
* decl.c (gfc_match_end): Add COMP_OMP_STRICTLY_STRUCTURED_BLOCK case
together with COMP_BLOCK.
* parse.c (parse_omp_structured_block): Change return type to
'gfc_statement', add handling for strictly-structured block case, adjust
recursive calls to parse_omp_structured_block.
(parse_executable): Adjust calls to parse_omp_structured_block.
* parse.h (enum gfc_compile_state): Add
COMP_OMP_STRICTLY_STRUCTURED_BLOCK.
* trans-openmp.c (gfc_trans_omp_workshare): Add EXEC_BLOCK case
handling.
gcc/testsuite/ChangeLog:
* gfortran.dg/gomp/cancel-1.f90: Adjust testcase.
* gfortran.dg/gomp/nesting-3.f90: Adjust testcase.
* gfortran.dg/gomp/strictly-structured-block-1.f90: New test.
* gfortran.dg/gomp/strictly-structured-block-2.f90: New test.
* gfortran.dg/gomp/strictly-structured-block-3.f90: New test.
libgomp/ChangeLog:
* libgomp.texi (Support of strictly structured blocks in Fortran):
Adjust to 'Y'.
* testsuite/libgomp.fortran/task-reduction-16.f90: Adjust testcase.
