--- Comment #7 from Paul Thomas <pault at gcc dot gnu.org> --- Author: pault Date: Sat Feb 23 12:18:44 2019 New Revision: 269156 URL: https://gcc.gnu.org/viewcvs?rev=269156&root=gcc&view=rev Log: 2019-02-23 Paul Thomas <pa...@gcc.gnu.org> PR fortran/89385 PR fortran/89366 * decl.c (gfc_verify_c_interop_param): Restriction on string length being one is lifted for F2018. * trans-expr.c (gfc_conv_gfc_desc_to_cfi_desc): For scalar characters with intent in, make a temporary and copy the result of the expression evaluation into it. (gfc_conv_procedure_call): Set a flag for character formal args having a character length that is not unity. If the procedure is bind C, call gfc_conv_gfc_desc_to_cfi_desc in this case. Also, extend bind C calls to unconditionally convert both pointers and allocatable expressions. 2019-02-23 Paul Thomas <pa...@gcc.gnu.org> PR fortran/89385 * gfortran.dg/ISO_Fortran_binding_1.f90 : Correct test for previously incorrect lbound for allocatable expressions. Also correct stop values to avoid repetition. * gfortran.dg/ISO_Fortran_binding_5.f90 : New test * gfortran.dg/ISO_Fortran_binding_5.c : Support previous test. PR fortran/89366 * gfortran.dg/ISO_Fortran_binding_6.f90 : New test * gfortran.dg/ISO_Fortran_binding_6.c : Support previous test. * gfortran.dg/pr32599.f03 : Set standard to F2008. 2019-02-23 Paul Thomas <pa...@gcc.gnu.org> PR fortran/89385 PR fortran/89366 * runtime/ISO_Fortran_binding.c (cfi_desc_to_gfc_desc) : In the interchange between character and derived, the character type was being set incorrectly. (gfc_desc_to_cfi_desc) : Eliminate the interchange of types in this function. Do not add the kind and length information to the type field of structures. Lbounds were incorrectly being set to zero for allocatable and pointer descriptors. Should have been non-pointer, non-allocatables that received this treatment.
