--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Paul Thomas <pa...@gcc.gnu.org>: https://gcc.gnu.org/g:b9294757f82aae8de6d98c122cd4e3b98f685217 commit r15-386-gb9294757f82aae8de6d98c122cd4e3b98f685217 Author: Paul Thomas <pa...@gcc.gnu.org> Date: Sun May 12 06:59:45 2024 +0100 Fortran: Unlimited polymorphic intrinsic function arguments [PR84006] 2024-05-12 Paul Thomas <pa...@gcc.gnu.org> gcc/fortran PR fortran/84006 PR fortran/100027 PR fortran/98534 * iresolve.cc (gfc_resolve_transfer): Emit a TODO error for unlimited polymorphic mold. * trans-expr.cc (gfc_resize_class_size_with_len): Use the fold even if a block is not available in which to fix the result. (trans_class_assignment): Enable correct assignment of character expressions to unlimited polymorphic variables using lhs _len field and rse string_length. * trans-intrinsic.cc (gfc_conv_intrinsic_storage_size): Extract the class expression so that the unlimited polymorphic class expression can be used in gfc_resize_class_size_with_len to obtain the storage size for character payloads. Guard the use of GFC_DECL_SAVED_DESCRIPTOR by testing for DECL_LANG_SPECIFIC to prevent the ICE. Also, invert the order to use the class expression extracted from the argument. (gfc_conv_intrinsic_transfer): In same way as 'storage_size', use the _len field to obtaining the correct length for arg 1. Add a branch for the element size in bytes of class expressions with provision to make use of the unlimited polymorphic _len field. Again, the class references are explicitly identified. 'mold_expr' was already declared. Use it instead of 'arg'. Do not fix 'dest_word_len' for deferred character sources because reallocation on assign makes use of it before it is assigned. gcc/testsuite/ PR fortran/84006 PR fortran/100027 * gfortran.dg/storage_size_7.f90: New test.
