[Yuri Per via Phabricator via llvm-commits]

yuri added a comment.

I have found out which optimization is applied by gcc but not by clang and did it manually. Executions times for new version:

| compiler | HEAD   | fibers |
| -------- | ------ | ------ |
| gcc 8.2  | 100.0% | 94.4%  |
| clang    | 112.4% | 94.1%  |
|
