[libcxx-commits] [PATCH] D63063: Bug 42208: speeding up std::merge

[Roman Lebedev via Phabricator via libcxx-commits]

lebedev.ri added a comment.

Have you analyzed, how much is this a problem of the actual implementation (in libc++), and how much of the llvm optimization passes?
I.e. are there some obvious failures of the llvm opts?
