[libcxx-commits] [PATCH] D118329: [libc++] Optimize algorithms on uninitialized memory for trivial types.

[Arthur O'Dwyer via Phabricator via libcxx-commits]

Quuxplusone added a comment.

FWIW, libc++'s historical position on this kind of optimization (which I associate particularly with Marshall's tenure) is "libc++ should do the simple thing; file a codegen bug against //Clang// if it's failing to optimize our simple template code for some trivial type."  TBF, I have not looked closely at this PR to know whether that attitude would be unfair here for some reason.
Do you have a Godbolt of the codegen before and after? (You should.)
