Make the front-end emit the right type for CHARACTER(C_CHAR), VALUE arguments to BIND(C) procedures. They are scalar integers of C type char, and should be emitted as such. They are not strings or arrays, and are not promoted to C int, either. gcc/fortran/ChangeLog: PR fortran/103828 * trans-decl.c (generate_local_decl): Do not call gfc_conv_scalar_char_value(), but check the type tree. * trans-expr.c (gfc_conv_scalar_char_value): Rename to conv_scalar_char_value, do not alter type tree. (gfc_conv_procedure_call): Adjust call to renamed conv_scalar_char_value() function. * trans-types.c (gfc_sym_type): Take care of CHARACTER(C_CHAR), VALUE arguments. * trans.h (gfc_conv_scalar_char_value): Remove prototype. gcc/testsuite/ChangeLog: PR fortran/103828 * gfortran.dg/c_char_tests_3.f90: New file. * gfortran.dg/c_char_tests_3_c.c: New file. * gfortran.dg/c_char_tests_4.f90: New file. * gfortran.dg/c_char_tests_5.f90: New file. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
