[PATCH] D31234: Implement P0599 - noexcept for hash functions

[Marshall Clow via Phabricator via cfe-commits]

mclow.lists created this revision.

Mark most of the hash functions provided by libc++ as noexcept; the exceptions being `optional` and `variant`.
Tests to ensure this.

There's still some investigation to be done on `unique_ptr` and fancy pointer support, but that can come later.
