[libcxx-commits] [PATCH] D65667: [libcxx] Avoid destructor call for error_category singletons

[Louis Dionne via Phabricator via libcxx-commits]

ldionne updated this revision to Diff 555865.
ldionne added a comment.

Re-introduce the union trick which is needed to implement nodestroy semantics on compilers that don't support the nodestroy attribute.

While we're at it, drop the nodestroy attribute since the union trick is enough.
