The first change is a simple, generic Fortran change.
Without it, external declarations have odd locations
(namely their input_location):
gcc/testsuite/gfortran.dg/gomp/dispatch-11.f90:67:46:
67 | !$omp dispatch interop(obj2, obj1) device(3)
| ^
note: ‘declare variant’ candidate ‘repl2’ declared here
While with the change, i.e. gfc_get_location (&sym->declared_at),
we get:
gcc/testsuite/gfortran.dg/gomp/dispatch-11.f90:25:5:
25 | subroutine base2 (x, y)
| ^~~~~~~~~~~~~~~~
note: ‘base2’ declared here
I bet there are several other cases where we could/should
improve the location data ...
* * *
Additionally, this patch adds the 'interop' clause to OpenMP's
'dispatch' clause.
That change is a bit boring until also the 'append_args' clause
of 'declare variant' is implemented, but it is a first step and
already gives the proper middle end diagnostic. Otherwise it is
just a list and the existing diagnostic can be reused.
The only special part is that the list is ordered, which means
that C/C++ and Fortran have to agree on the order to make it
easier in the middle end. Thus, we store the clause arguments in
reverse order, matching how a tree list is trivially constructed.
* * *
Comments, remarks, suggestions?
Otherwise, I regard the common Fortran code as obvious - and
the OpenMP part covered by my (co)maintainership.
Hence, I intent to commit it later today.
Nonetheless, I am happy about (nearly) any comment - it is
useful if someone proof reads a patch :-)
Thanks,
Tobias
Fortran: Fix location_t in gfc_get_extern_function_decl; support 'omp dispatch interop'
The declaration created by gfc_get_extern_function_decl used input_location
as DECL_SOURCE_LOCATION, which gave rather odd results with 'declared here'
diagnostic. - It is much more useful to use the gfc_symbol's declated_at,
which this commit now dows.
Additionally, it adds support for the 'interop' clause of OpenMP's
'dispatch' directive. As the argument order matters,
gfc_match_omp_variable_list gained a 'reverse_order' flag to use the
same order as the C/C++ parser.
gcc/fortran/ChangeLog:
* gfortran.h: Add OMP_LIST_INTEROP to the unnamed OMP_LIST_ enum.
* openmp.cc (gfc_match_omp_variable_list): Add reverse_order
boolean argument, defaulting to false.
(enum omp_mask2, OMP_DISPATCH_CLAUSES): Add OMP_CLAUSE_INTEROP.
(gfc_match_omp_clauses, resolve_omp_clauses): Handle dispatch's
'interop' clause.
* trans-decl.cc (gfc_get_extern_function_decl): Use sym->declared_at
instead input_location as DECL_SOURCE_LOCATION.
* trans-openmp.cc (gfc_trans_omp_clauses): Handle OMP_LIST_INTEROP.
gcc/testsuite/ChangeLog:
* gfortran.dg/goacc/routine-external-level-of-parallelism-2.f: Update
xfail'ed 'dg-bogus' for the better 'declared here' location.
* gfortran.dg/gomp/dispatch-11.f90: New test.
* gfortran.dg/gomp/dispatch-12.f90: New test.
