This regression came about because of a change in the way
types are displayed in error messages. The character
representation is also used to calculate the hashes for
our types, so this patch restores the old behavior if
we are indeed calculating a hash.
The test case also checks for the specific hash value because
changing that would be an ABI change, which we should not
be doing unintentionally.

Our finalization handling is a mess. Really, we should get to try and get
this fixed for gcc 11.
In the meantime, here is a patch which fixes a regression I introduced
when fixing a regression with a memory leak. The important thing
here is to realize that we do not need to finalize (and deallocate)
multiple times for the same expression and the same component
in the same namespace. It might cause code size regressions, but
better big code than wrong code...

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 v5 of the patch. v4 was applied but caused breakage on big
endian targets. These have been fixed and tested, thanks to access to
the GCC compile farm.
Overview of 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, i686-pc-linux-gnu and
powerpc64-unknown-linux-gnu. Also regtested all three targets by
modifying gfortran-dg.exp to also test with "-g -flto", no new
failures observed.

missing -Wformat-overflow with %s and non-member array arguments
-Wformat-overflow uses the routine "get_range_strlen" to decide the
maximum string length, however, currently "get_range_strlen" misses
the handling of non-member arrays.
Adding the handling of non-member array resolves the issue.
Adding test case pr79538.c into gcc.dg.
During gcc bootstrap, 2 source files (c-family/c-cppbuiltin.c,
fortran/class.c) were detected new warnings by -Wformat-overflow
due to the new handling of non-member array in "get_range_strlen".
in order to avoid these new warnings and continue with bootstrap,
updating these 2 files to avoid the warnings.
in c-family/c-cppbuiltin.c, the warning is following:
../../latest_gcc_2/gcc/c-family/c-cppbuiltin.c:1627:15: note:
‘sprintf’ output 2 or more bytes (assuming 257) into a destination
of size 256
sprintf (buf1, "%s=%s", macro, buf2);
~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~
in the above, buf1 and buf2 are declared as:
char buf1[256], buf2[256];
i.e, buf1 and buf2 have same size. adjusting the size of buf1 and
buf2 resolves the warning.
fortran/class.c has the similar issue as above. Instead of adjusting
size of the buffers, replacing sprintf with xasprintf is a better
solution for these cases.

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.
