https://gcc.gnu.org/g:d8b4cd79d1a81023b29708d9f13d0642bc2545d0 commit d8b4cd79d1a81023b29708d9f13d0642bc2545d0 Author: Tobias Burnus <[email protected]> Date: Sat May 2 22:25:48 2026 +0200 Fortran/OpenMP: cleanup gfc_free_omp_namelist Move the logic to deduce what needs to be freed from the caller to the callee by passing the OMP_LIST_... enum value instead of multiple bool arguments to gfc_free_omp_namelist. Additionally, add the name 'gfc_omp_list_type' to the existing OMP_LIST_... enum values and OMP_LIST_NONE (== OMP_LIST_NUM) as special value. As an enum is available, use it properly and replace 0 by OMP_LIST_FIRST in the list walks. gcc/fortran/ChangeLog: * gfortran.h (enum gfc_omp_list_type): Add this name to the existing OMP_LIST... enum; add OMP_LIST_NONE. (gfc_free_omp_namelist): Take that enum as arg instead of bool args. * match.cc (gfc_free_omp_namelist): Update. * openmp.cc (gfc_free_omp_clauses, gfc_free_omp_declare_variant_list, gfc_match_omp_clause_reduction, gfc_match_omp_clauses, gfc_match_omp_allocate, gfc_match_omp_flush, gfc_match_omp_declare_target, resolve_omp_clauses, gfc_resolve_omp_parallel_blocks, resolve_omp_do, gfc_resolve_oacc_blocks, gfc_resolve_oacc_declare): Update gfc_free_omp_namelist call and used enum type instead of int. * st.cc (gfc_free_statement): Likewise.
