Hello world,
the attached patch creates an unsigned "standard" for the
gfc_option.allow_std field.
One of the main reason why people want UNSIGNED for Fortran is
interfacing for C.
This is a preparation for further work on the ISO_C_BINDING constants.
That, we do via iso-c-binding.def , whose last field is a standard
for the constant to be defined for the standard in question, which is
then checked. I could try and invent a different method for this,
but I'd rather not.
So, OK for trunk? Other, better ideas?
ChangeLog was missing, here it is. Also regression-tested.
gcc/fortran/ChangeLog:
* intrinsic.cc (add_functions): Convert uint and
selected_unsigned_kind to GFC_STD_UNSIGNED.
(gfc_check_intrinsic_standard): Handle GFC_STD_UNSIGNED.
* libgfortran.h (GFC_STD_UNSIGNED): Add.
* options.cc (gfc_post_options): Set GFC_STD_UNSIGNED
if -funsigned is set.
