The previous commit moved some code from `rustc_query_system`, which doesn't have access to `TyCtxt` and `QueryCtxt`, to `rustc_query_impl`, which does. We can now remove quite a bit of indirection. - Three methods in `trait QueryContext` are no longer needed (`next_job_id`, `current_query_job`, `start_query`). As a result, `QueryCtxt`'s trait impls of these methods are changed to inherent methods. - `qcx: Q::Qcx` parameters are simplified to `qcx: QueryCtxt<'tcx>`. - `*qcx.dep_context()` occurrences are simplified to `qcx.tcx`, and things like `qcx.dep_context().profiler()` become `qcx.tcx.prof`. - `DepGraphData<<Q::Qcx as HasDepContext>::Deps>` becomes `DepGraphData<DepsType>`. In short, various layers of indirection and abstraction are cut away. The resulting code is simpler, more concrete, and easier to understand. It's a good demonstration of the benefits of eliminating `rustc_query_system`, and there will be more to come. |
