PR 78534 Change character length from int to size_t
In order to handle large character lengths on (L)LP64 targets, switch the GFortran character length from an int to a size_t. This is an ABI change, as procedures with character arguments take hidden arguments with the character length. I also changed the _size member in vtables from int to size_t, as there were some cases where character lengths and sizes were apparently mixed up and caused regressions otherwise. Although I haven't tested, this might enable very large derived types as well. Also, as there are some places in the frontend were negative character lengths are used as special flag values, in the frontend the character length is handled as a signed variable of the same size as a size_t, although in the runtime library it really is size_t. I haven't changed the character length variables for the co-array intrinsics, as this is something that may need to be synchronized with OpenCoarrays. This is v4 of the patch. v3 was applied but had to reverted due to breaking bootstrap. The fix is in resolve.c:resolve_charlen, where it's necessary to check that an expression is constant before using mpz_sgn. Overview of v3 of the patch: All the issues pointed out by FX's review of v2 have been fixed. In particular, there are now new functions gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT instead of a long value. Similarly, gfc_get_int_expr now takes a HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by gfc_extract_hwi. Also, the preliminary work to handle gfc_charlen_type_node being unsigned has been removed. Regtested on x86_64-pc-linux-gnu and i686-pc-linux-gnu. frontend: 2017-01-13 Janne Blomqvist <jb@gcc.gnu.org> PR fortran/78534 PR fortran/66310 * class.c (gfc_find_derived_vtab): Use gfc_size_kind instead of hardcoded kind.

For arguments of @code{CHARACTER} type, the character length is passed

by reference, otherwise by value. The character length has the type
|

different to older versions of the GNU Fortran compiler, where the

define the corresponding C prototype as follows:
