Unrolled perf run results should include a link to the relevant PR
When doing unrolled perf runs to investigate regressions in a rollup, it would be helpful if the automated result post would include a link to the PR whose unrolled build is being tested. That would make it easier to keep track of which results correspond to which rolled-up PR.
Currently this has to be done manually, by checking prior comments or by looking up the commit hash in the table of unrolled builds.
E.g. see https://github.com/rust-lang/rust/pull/145589#issuecomment-3203808157, where I manually added the PR link afterwards.
(No idea how feasible this is at an implementation level.)
Hmm, I see the point, but from an implementation perspective that would be quite complicated. What I tend to do instead is to do the unrolled perf. runs on the PR itself (not on the rollup), I think that solves this issue and is generally better. It also allows to queue multiple unrolles perf. runs in parallel.
Yeah, I'm not surprised to hear that it would be unreasonably tricky. But I'm glad I asked.
