`rustc_with_all_queries` currently provides information about all queries. Also, a caller can provide an ad hoc list of extra non-queries. This is used by `define_queries` for non-query dep kinds: `Null`, `Red`, etc. This is pretty hacky. This commit changes `rustc_with_all_queries` so that the non-queries information is available to all callers. (Some callers ignore the non-query information.) This is done by adding `non_query` entries to the primary list of queries in `rustc_queries!`.
Currently `define_dep_nodes` produces a macro `make_dep_kind_array` that encodes the names of non-queries followed by queries. This macro is used by `make_dep_kind_vtables` to make the full array of vtables, by referring to vtable constructor functions that are put into `mod _dep_kind_vtable_ctors`. Pretty weird! This commit takes advantage of the previous commit's changes to `rustc_with_all_queries`, which makes both query and non-query information available. A new call to `rustc_with_all_queries` is used to construct the vtable array. (This moves some dep_kind_vtable code from `plumbing.rs` to `dep_kind_vtables.rs`, which is good.) It's straightforward now with iterator chaining, and `mod _dep_kind_vtable_ctors` is no longer needed.
"i.e." is short for the Latin "id est" and thus both letters should be followed by periods.

…ueries, r=Zalathar Rejig `rustc_with_all_queries!` There are three things relating to `rustc_with_all_queries!` that have been bugging me. - `rustc_with_all_queries!`'s ability to receive `extra_fake_queries` lines like `[] fn Null(()) -> (),` where the only real thing is the `Null`, and everything is just pretending to be a normal query, ugh. - `make_dep_kind_array!`: a macro produced by one macro (`define_dep_nodes!`) and used by another macro (`define_queries!`) in another crate, ugh. - The `_dep_kind_vtable_ctors` module, which is a special module with no actual code that serves just a way of collecting vtable constructors from two different places so they can be referred to by `make_dep_kind_array!`, ugh. By making some adjustments to how `rustc_with_all_queries!` works, all three of these things are eliminated. r? @Zalathar
…res, r=JonathanBrouwer Lint unused features *[View all comments](https://triagebot.infra.rust-lang.org/gh-comments/rust-lang/rust/pull/152164)* Fixes rust-lang#44232 Fixes rust-lang#151752 --- This PR records used features through query side effect, then reports unsued features finally.
…tuples, r=jdonszelmann don't emit `unused_results` lint for tuples of "trivial" types r? @jdonszelmann Fixes rust-lang#153144. So it turns out rust-lang#153018 had a sneaky behavior change in the way tuples are handled and the old behavior wasn't tested. Consider these tuples: ```rust ((), ()); ((), 1); ``` Neither of them is `must_use`, so they are potential candidates for `unused_results`. So the question is whatever said tuples are considered "trivial" and thus if they end up emitting `unused_results` or not. Here is a comparison table between PRs: <table> <tr><td>stable</td><td>After rust-lang#153018</td><td>After this PR</td></tr><tr><td> ```rust ((), ()); // trivial ((), 1); // trivial ``` </td> <td> ```rust ((), ()); //~ warn: unused_results ((), 1); //~ warn: unused_results ``` </td> <td> ```rust ((), ()); // trivial ((), 1); //~ warn: unused_results ``` </td> </tr> <tr> <td> tuples are trivial if **any** of their fields are trivial </td> <td> tuples are never trivial </td> <td> tuples are trivial if **all** of their fields are trivial </td> </tr> </table>
