--- Comment #14 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Mikael Morin <mik...@gcc.gnu.org>: https://gcc.gnu.org/g:77bbf69d2981dafc2ef3e59bfbefb645d88bab9d commit r13-2841-g77bbf69d2981dafc2ef3e59bfbefb645d88bab9d Author: Mikael Morin <mik...@gcc.gnu.org> Date: Thu Sep 1 12:35:07 2022 +0200 fortran: Support clobbering of derived types [PR41453] This adds support for clobbering of non-polymorphic derived type variables, when they are passed as actual argument whose associated dummy has the INTENT(OUT) attribute. We avoid to play with non-constant type sizes or class descriptors by requiring that the types are derived (not class) and strictly matching, and by excluding parameterized derived types. Types that are used in the callee are also excluded: they are types with allocatable components (the components will be deallocated), and finalizable types or types with finalizable components (they will be passed to finalization routines). PR fortran/41453 gcc/fortran/ChangeLog: * trans-expr.cc (gfc_conv_procedure_call): Allow strictly matching derived types. gcc/testsuite/ChangeLog: * gfortran.dg/intent_optimize_10.f90: New test.
