--- 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.=20

So the question becomes why was __builtin_unreachable marked as const, I ha=
ve
no idea.
Anyways reconfirmed.=
