--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Julian Brown <ju...@gcc.gnu.org>: https://gcc.gnu.org/g:330b9a8d87dd73e10539da618496ad4964fee26d commit r13-4703-g330b9a8d87dd73e10539da618496ad4964fee26d Author: Julian Brown <jul...@codesourcery.com> Date: Tue Dec 6 23:10:58 2022 +0000 OpenMP: Duplicate checking for map clauses in Fortran (PR107214) This patch adds duplicate checking for OpenMP "map" clauses, taking some cues from the implementation for C in c-typeck.cc:c_finish_omp_clauses (and similar for C++). In addition to the existing use of the "mark" and "comp_mark" bitfields in the gfc_symbol structure, the patch adds several new bits handling duplicate checking within various categories of clause types. If "mark" is being used for map clauses, we need to use different bits for other clauses for cases where "map" and some other clause can refer to the same symbol (e.g. "map(n) shared(n)"). 2022-12-06 Julian Brown <jul...@codesourcery.com> gcc/fortran/ PR fortran/107214 * gfortran.h (gfc_symbol): Add data_mark, dev_mark, gen_mark and reduc_mark bitfields. * openmp.cc (resolve_omp_clauses): Use above bitfields to improve duplicate clause detection. gcc/testsuite/ PR fortran/107214 * gfortran.dg/gomp/pr107214.f90: New test. * gfortran.dg/gomp/pr107214-2.f90: New test. * gfortran.dg/gomp/pr107214-3.f90: New test. * gfortran.dg/gomp/pr107214-4.f90: New test. * gfortran.dg/gomp/pr107214-5.f90: New test. * gfortran.dg/gomp/pr107214-6.f90: New test. * gfortran.dg/gomp/pr107214-7.f90: New test. * gfortran.dg/gomp/pr107214-8.f90: New test.
