I've found out that int128_integer_type_node and
long_long_integer_type_node are NULL at the moment of definition of
the graphite_expression_size_type. Maybe we should use
long_long_integer_type_node, because, as you said before, using of
signed 64 has also been proved to be very robust. What do you think
about this?

I do not fully understand this message. You first say that
long_long_integer_type_node is NULL, but then want to use this. This does
not seem to be a solution. Most likely it is the solution, but the problem
description makes it hard to understand it. Is the problem
caused by initialization order issues? Or why are such types NULL?

Because they are not available on all targets or for all languages.

I suggest you use the largest available integer mode via
mode = mode_for_size (MAX_FIXED_MODE_SIZE, MODE_INT, 0);
type = build_nonstandard_integer_type (GET_MODE_PRECISION (mode), [01]);

Roman, can you give this a shot?
