[PATCH] D54355: Use is.constant intrinsic for __builtin_constant_p

[Bill Wendling via Phabricator via cfe-commits]

void added a comment.

The issue is that "`n`" is expecting an immediate value, but the result of the ternary operator isn't calculated by the front-end, because it doesn't "know" that the evaluation of `__builtin_constant_p` shouldn't be delayed (it being compiled at `-O0`). I suspect that this issue will also happen with the "`i`" constraint.
