Reorder check_item_type diagnostics so they occur next to the corresponding `check_well_formed` diagnostics #117213

oli-obk · 2023-10-26T11:15:55Z

The first commit is just a cleanup.

The second commit moves most checks from check_mod_item_types into check_well_formed, invoking the checks in lockstep per-item instead of iterating over all items twice.

I don't expect a perf effect, but technically some incremental cache dep graph could be affected

cc @rust-lang/rustdoc I had to revert some of #97842, as that only works if we avoid some sanity checks. We'll need to figure out a new way to get whatever was desired by that PR (though my changes did not affect any test output I think?)

@GuillaumeGomez

If it's necessary to make other cleanups on the compiler, reverting #97842 is acceptable. I'll make a follow-up PR to accomplish the same thing in a different way.

GuillaumeGomez · 2023-10-26T17:40:01Z

I'm not against it but you're the person who worked on it so just wanted you to be aware of it. :)

The 1.4% regression must be noise, it is purely in codegen, and this PR does not affect codegen.

The other regressions are real, either in incremental cache loading or in wf-check. Surprising, so I'll dig into those.

oli-obk · 2024-01-03T14:32:14Z

The regression is because we actually need to do some work when ensureing a query:
