--- Comment #30 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jerry DeLisle <jvdeli...@gcc.gnu.org>: https://gcc.gnu.org/g:efc0981077a70c4de4596f682c4aeade07ec2f17 commit r15-6471-gefc0981077a70c4de4596f682c4aeade07ec2f17 Author: Steven G. Kargl <kar...@comcast.net> Date: Sun Dec 29 14:19:18 2024 -0800 Fortran: Implement f_c_string function. Fortran 2023 has added the new intrinsic function F_C_STRING to convert fortran strings of default character kind to a null terminated C string. Contributions from Steve Kargl, Harald Anlauf, FX Coudert, Mikael Morin, and Jerry DeLisle. PR fortran/117643 gcc/fortran/ChangeLog: * check.cc (gfc_check_f_c_string): Check arguments of f_c_string(). * gfortran.h (enum gfc_isym_id): New symbol GFC_ISYM_F_C_STRING. * intrinsic.cc (add_functions): Add the ISO C Binding routine f_c_string(). Wrap nearby long line to less than 80 characters. * intrinsic.h (gfc_check_f_c_string): Prototype for gfc_check_f_c_string(). * iso-c-binding.def (NAMED_FUNCTION): Declare for ISO C Binding routine f_c_string(). * primary.cc (gfc_match_rvalue): Fix comment that has been untrue since 2011. Add ISOCBINDING_F_C_STRING to conditional. * trans-intrinsic.cc (conv_trim): Specialized version of trim() for f_c_string(). (gfc_conv_intrinsic_function): Use GFC_ISYM_F_C_STRING to trigger in-lining. gcc/testsuite/ChangeLog: * gfortran.dg/f_c_string1.f90: New test. * gfortran.dg/f_c_string2.f90: New test.
