Enable -Zdrop-tracking-mir by default #107421

cjgillot · 2023-01-28T18:45:54Z

This PR enables the drop-tracking-mir flag by default. This flag was initially implemented in #101692.

This flag computes auto-traits on generators based on their analysis MIR, instead of trying to compute on the HIR body. This removes the need for HIR-based drop-tracking, as we can now reuse the same code to compute generator witness types and to compute generator interior fields.

Overall result: ❌✅ regressions and improvements - ACTION NEEDED

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

Next Steps: If you can justify the regressions found in this try perf run, please indicate this with @rustbot label: +perf-regression-triaged along with sufficient written justification. If you cannot justify the regressions please fix the regressions and do another perf run. If the next run shows neutral or positive results, the label will be automatically removed.

rylev · 2023-09-26T18:55:06Z

@cjgillot @oli-obk it seems the regressions to await-call-tree are real. I'm having trouble running cachegrind right now. Do either of have any idea what might be causing this regression?

oli-obk · 2023-09-27T06:59:03Z

~~According to the graph, perf of await-call-tree went back to normal with the next perf run, or is the darker area on the graph just any perf run, instead of perf runs on master?~~

edit: oh this is the relative change, not the absolute value. oops

Kobzol · 2023-09-27T07:05:22Z

That's the second time in this week's triage that the "relativeness" of the graph tripped someone up. Would an absolute graph be more intuitive?

oli-obk · 2023-09-27T07:06:37Z

No ^^ I know that, and I read it correctly most of the time.
