c: ICE with nullptr as case expression [PR108424]
In this ICE-on-invalid, we crash on
gcc_assert (INTEGRAL_TYPE_P (type));
in perform_integral_promotions, because a nullptr is an INTEGER_CST,
but not INTEGRAL_TYPE_P, and check_case_value is only checking the
former. In the test I'm testing other "shall be an integral constant
expression" contexts as well.
PR c/108424
gcc/c-family/ChangeLog:
* c-common.cc (check_case_value): Check INTEGRAL_TYPE_P.
gcc/testsuite/ChangeLog:
* gcc.dg/c2x-nullptr-6.c: New test.
