Perf run started. Sorry for the delay. |
|
Hey @Mark-Simulacrum, did that perf run ever finish? |
|
Yes. I generally forget to check back in; they auto-queue and finish within 4 hours at most, and the URLs are fairly easy to generate. Eventually this will be automated... |
|
Thanks @Mark-Simulacrum! I see now how I can compose these URLs myself. |
|
This is now ready for review, @nikomatsakis. |
|
☔ The latest upstream changes (presumably #46550) made this pull request unmergeable. Please resolve the merge conflicts. |

incr.comp.: Revert hashing optimization that caused regression. This PR reverts part of #46562 which caused [a regression in the crossbeam rust-icci](https://travis-ci.org/rust-icci/crossbeam/builds/316574774) test. I don't know what the problem is exactly yet. Fortunately, the problematic part is also the less important one, so reverting should not have much impact on performance. r? @eddyb
