Some changes occurred to the core trait solver cc @rust-lang/initiative-trait-system-refactor |
|
We discussed this, I'm happy with landing this for now I guess. We should track this optimization somewhere (ideally with a label in the new solver repo) so we can revisit it. @bors r+ |

…r=<try> drop region constraints for ambiguous goals See the comment in `compute_external_query_constraints`. While the underlying issue is preexisting, this fixes a bug introduced by rust-lang#125343. It slightly weakens the leak chec, even if we didn't have any test which was affected. I want to write such a test before merging this PR. r? `@compiler-errors`

…, r=compiler-errors `-Znext-solver`: eagerly normalize when adding goals fixes rust-lang#125269. I am not totally with this fix and going to keep this open until we have a more general discussion about how to handle hangs caused by lazy norm in the new solver.
