<pre>I would expect this static_assert to fail:
static_assert((void(__builtin_assume(false)), true));
I believe this change would fit into the constexpr model better. constexpr
evaluation is required to diagnose undefined behavior, and __builtin_assume
states that if the condition is false, the behavior is undefined.</pre>
