Add post-mono MIR passes to make mono-reachable analysis more accurate #131650

saethlin · 2024-10-13T12:45:35Z

Debug full/incr-full builds regress, as far as I can tell this is just the expense of cloning, then monomorphizing, then caching the MIR.

Overall result: ❌✅ regressions and improvements - please read the text below

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.

Add post-mono MIR passes to make mono-reachable analysis more accurate As of rust-lang#131650 (comment) I believe most of the incr overhead comes from re-computing, re-encoding, and loading a lot more MIR when all we're actually doing is traversing through it. I think that can be addressed by caching a query that looks up the mentioned/used items for an Instance. I think the full-build regressions are pretty much just the expense of cloning, then monomorphizing, then caching the MIR.

⌛ Trying commit 3647120 with merge 4797466...

Add post-mono MIR passes to make mono-reachable analysis more accurate Debug full/incr-full builds regress, as far as I can tell this is just the expense of cloning, then monomorphizing, then caching the MIR.

Finished benchmarking commit (4797466): comparison URL.

Overall result: ❌✅ regressions and improvements - please read the text below

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.

@bors rollup=never
@rustbot label: -S-waiting-on-perf +perf-regression
