  Hi!

The following testcaser ICEs during gimplification, because
count_type_elements doesn't handle BITINT_TYPE.  It should handle it like
other integral types.

Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

2023-12-07  Jakub Jelinek  <jakub@redhat.com>

	PR middle-end/112881
	* expr.cc (count_type_elements): Handle BITINT_TYPE like INTEGER_TYPE.

	* gcc.dg/bitint-50.c: New test.


	Jakub
