bors 6d395a1c29 Auto merge of #85186 - nikomatsakis:issue-83538-polluted-cache, r=jackh726 ... have on_completion record subcycles have on_completion record subcycles Rework `on_completion` method so that it removes all provisional cache entries that are "below" a completed node (while leaving those entries that are not below the node). This corrects an imprecise result that could in turn lead to an incremental compilation failure. Under the old scheme, if you had: * A depends on... * B depends on A * C depends on... * D depends on C * T: 'static then the provisional results for A, B, C, and D would all be entangled. Thus, if A was `EvaluatedToOkModuloRegions` (because of that final condition), then the result for C and D would also be demoted to "ok modulo regions". In reality, though, the result for C depends only on C and itself, and is not dependent on regions. If we happen to evaluate the cycle starting from C, we would never reach A, and hence the result would be "ok". Under the new scheme, the provisional results for C and D are moved to the permanent cache immediately and are not affected by the result of A.
