[PATCH] D136737: [Draft] [clang] Add builtin_unspecified_value

[Erich Keane via Phabricator via cfe-commits]

erichkeane added a comment.

It doesn't really  make sense to me why this is an AST node expr-node-type rather than just being a call to a builtin (that'll likely  need to take a var as a parameter)?  We can make that builtin result in a freeze/poison value if necessary.

So something like:
`_si128 x = __builtin_magic_unspecified(x);`
