--- Comment #2 from Paul Thomas <pault at gcc dot gnu.org> --- Author: pault Date: Fri May 10 07:59:42 2019 New Revision: 271057 URL: https://gcc.gnu.org/viewcvs?rev=271057&root=gcc&view=rev Log: 2019-05-10 Paul Thomas <pa...@gcc.gnu.org> PR fortran/90093 * trans-decl.c (convert_CFI_desc): Test that the dummy is present before doing any of the conversions. PR fortran/90352 * decl.c (gfc_verify_c_interop_param): Restore the error for charlen > 1 actual arguments passed to bind(C) procs. Clean up trailing white space. PR fortran/90355 * trans-array.c (gfc_trans_create_temp_array): Set the 'span' field to the element length for all types. (gfc_conv_expr_descriptor): The force_no_tmp flag is used to prevent temporary creation, especially for substrings. * trans-decl.c (gfc_trans_deferred_vars): Rather than assert that the backend decl for the string length is non-null, use it as a condition before calling gfc_trans_vla_type_sizes. * trans-expr.c (gfc_conv_gfc_desc_to_cfi_desc): 'force_no_tmp' is set before calling gfc_conv_expr_descriptor. * trans.c (get_array_span): Move the code for extracting 'span' from gfc_build_array_ref to this function. This is specific to descriptors that are component and indirect references. * trans.h : Add the force_no_tmp flag bitfield to gfc_se. 2019-05-10 Paul Thomas <pa...@gcc.gnu.org> PR fortran/90093 * gfortran.dg/ISO_Fortran_binding_12.f90: New test. * gfortran.dg/ISO_Fortran_binding_12.c: Supplementary code. PR fortran/90352 * gfortran.dg/iso_c_binding_char_1.f90: New test. PR fortran/90355 * gfortran.dg/ISO_Fortran_binding_4.f90: Add 'substr' to test the direct passing of substrings as descriptors to bind(C). * gfortran.dg/assign_10.f90: Increase the tree_dump count of 'atmp' to account for the setting of the 'span' field. * gfortran.dg/transpose_optimization_2.f90: Ditto.
