@RyanCavanaugh since the perf run came up clean I updated the baselines and cleaned up this a little bit further. Looking at the changed baselines it seems like a neat improvement to me :) |

@sandersn @ahejlsberg those are lines that were not at all here when I created this PR. When syncing with main now I removed the RelationComparisonResult.Reported - just like it was done everywhere else here but I'm not sure if this should actually be done here.
Those lines come from #55851

Hmm, the CI shows that this actually is important as now it's doing a lot of heavy work twice in this pathological case and the CI timeouts.
If we take a closer look at this baseline (even on main) we might notice that it's actually reporting 2 errors at the same location:
So perhaps If I manage to report this once, the perf problems will go away naturally.

We had this PR all this time and never merged it? Oh well. |

@gabritto does it overlap with some other fresh work/issue? I can certainly try to prioritize this PR more and bring it up to speed |
Member

Yeah, #57842, since we may report diagnostics out of order and therefore elaborations may jump around. |
Member
To give more details, I'm doing some diagnostics work in preparation for #57842. Right now I'm trying to have less duplicated diagnostics, but next on my list is to provide assignability elaboration consistently in editor scenarios, and as a consequence get rid of some of the diagnostics differences that arise when using #57842 vs not using them. |

I'm just opening this as a draft, even without updating baselines. It might be interesting to run the perf suite on this one.
