Remove save-analysis. #101841

nnethercote · 2022-09-15T07:42:15Z

Most tests involving save-analysis were removed, but I kept a few where the -Zsave-analysis was an add-on to the main thing being tested, rather than the main thing being tested.

Closes #43606

Overall result: no relevant changes - no 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.

Would it be possible to wait with merging of this, maybe 2-3 weeks? Due to this PR, I've switched cargo-udeps over to use binary depinfo, and made the 0.1.33 release, but it needs some time until the update arrives at users. On the other hand cargo-udeps has to be used with nightly rustc, so a removal would get to them very quickly.

lqd · 2022-09-15T19:14:49Z

@est31 there's a bit more work to be done here related to rustup, and will need FCP I think (which lasts at least 10 days or so IIRC), so there's time yeah.

nnethercote · 2022-09-15T20:45:45Z

The perf run shows that bootstrap time was reduced by about 4.6 seconds due to the removal of the rust_save_analysis crate.

nnethercote · 2022-09-16T00:54:45Z

I addressed all the comments about tests.

oli-obk · 2022-09-16T07:49:46Z

@rfcbot merge

The save-analysis framework has few users and all of them are willing to move away from it. We've sat on the removal plan for two years now without arguments for keeping it further.
