--- Comment #16 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Thomas Kथà¤nig <tkoe...@gcc.gnu.org>: https://gcc.gnu.org/g:3055d879edb1bc2a3923f92a5e681c8f6774fbc3 commit r11-2215-g3055d879edb1bc2a3923f92a5e681c8f6774fbc3 Author: Thomas Koenig <tkoe...@gcc.gnu.org> Date: Sun Jul 19 12:23:43 2020 +0200 Fix handling of implicit_pure by checking if non-pure procedures are called. Procedures are marked as implicit_pure if they fulfill the criteria of pure procedures. In this case, a procedure was not marked as not being implicit_pure which called another procedure, which had not yet been marked as not being implicit_impure. Fixed by iterating over all procedures, setting callers of procedures which are non-pure and non-implicit_pure as non-implicit_pure and doing this until no more procedure has been changed. gcc/fortran/ChangeLog: 2020-07-19 Thomas Koenig <tkoe...@gcc.gnu.org> PR fortran/96018 * frontend-passes.c (gfc_check_externals): Adjust formatting.
