--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
And then there was an issue where we convert __builtin_unreachable to
__builtin_trap which had the similar issue so we added:
DEF_GCC_BUILTIN (BUILT_IN_UNREACHABLE_TRAP, "unreachable trap",
BT_FN_VOID, ATTR_CONST_NORETURN_NOTHROW_LEAF_COLD_LIST)
instead, see PR 107300 for the issue there.
So the question becomes why was __builtin_unreachable marked as const, I have
no idea.
Anyways reconfirmed.
