c-format.c/Fortran: Support %wd / host-wide integer in gfc_error
This patch adds support for the 'll' (long double)
and 'w' (HOST_WIDE_INT) length modifiers to the
Fortran FE diagnostic function (gfc_error, gfc_warning, ...)
gcc/c-family/ChangeLog:
* c-format.c (gcc_gfc_length_specs): Add 'll' and 'w'.
(gcc_gfc_char_table): Add T9L_LL and T9L_ULL to
"di" and "u", respecitively; fill with BADLEN to match
size of 'types'.
(get_init_dynamic_hwi): Split off from ...
(init_dynamic_diag_info): ... here. Call it.
(init_dynamic_gfc_info): Call it.
gcc/fortran/ChangeLog:
* error.c
(error_uinteger): Take 'long long unsigned' instead
of 'long unsigned' as argumpent.
(error_integer): Take 'long long' instead of 'long'.
(error_hwuint, error_hwint): New.
(error_print): Update to handle 'll' and 'w'
length modifiers.
* simplify.c (substring_has_constant_len): Use '%wd'
in gfc_error.
