[PATCH] D41976: Low-hanging fruit optimization in string::__move_assign().

[Timothy VanSlyke via Phabricator via cfe-commits]

tvanslyke added a comment.

I'll add that the reason I felt compelled to submit this change was because perf was saying most of my program, that only ever moved strings, was spending a majority of it's time in string::reserve() calls.  If for no other reason, I think it's confusing for people to see string::reserve getting called when all they wanted was a move assignment.
