Fortran: Emit correct types for CHARACTER(C_CHAR), VALUE arguments
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.
