--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> --- So, where would be the best place to remove the VLA bounds from parameters of fn declarations? Some function called from c_write_global_declarations_1 and from walking BLOCK tree vars e.g. right before calling c_genericize in finish_function?
