--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:6d6df84dc031924cb95599a6c498aa27d3bceac4 commit r10-8294-g6d6df84dc031924cb95599a6c498aa27d3bceac4 Author: Jakub Jelinek <ja...@redhat.com> Date: Tue May 26 09:35:21 2020 +0200 openmp: Ensure copy ctor for composite distribute parallel for class iterators is instantiated [PR95197] During gimplification omp_finish_clause langhook is called in several places to add the language specific info to the clause like what default/copy ctors, dtors and assignment operators should be used. Unfortunately, if it refers to some not yet instantiated method, during gimplification it is too late and the methods will not be instantiated anymore. For other cases, the genericizer has code to detect those and instantiate whatever is needed, this change adds the same for distribute parallel for class iterators where we under the hood need a copy constructor for the iterator to implement it. 2020-05-26 Jakub Jelinek <ja...@redhat.com> PR c++/95197 * gimplify.c (find_combined_omp_for): Move to omp-general.c. * omp-general.h (find_combined_omp_for): Declare. * omp-general.c: Include tree-iterator.h. (find_combined_omp_for): New function, moved from gimplify.c. * cp-gimplify.c: Include omp-general.h. (cp_genericize_r) <case OMP_DISTRIBUTE>: For class iteration variables in composite distribute parallel for, instantiate copy ctor of their types.
