It has four different `insert` methods, with some duplication. This
commit finds the commonality and removes them all.
|
|
Because there is no real reason for it to be a separate struct.
- It has no methods.
- It's easy to confuse with the nearby `BorrowckInferContext` (which
does have methods).
- The `mut` ref to it in `TypeChecker` makes it seem like any of the
fields within might be mutable, but only two (`all_facts` and
`constraints`) actually are.
- Two of the fields are `pub(crate)` but can be private.
This change makes a lot of code more concise and readable.

It's unused.

It's strange to have a struct that contains a single anonymous field
that is an enum. This commit merges them. This does require increasing
the visibility of `TypeOfInfo` to `pub(crate)`, but that seems
worthwhile.
|
|
Mostly by wrapping overly long comment lines, plus a few other things.
|
|
So they're all in the one place. Also prepend with `crate::`, à la the
`unqualified_local_imports` lint.

Remove region from adjustments
It's not necessary to store this region, because it's only used in THIR and MemCat/ExprUse, both of which already basically only deal with erased regions anyways.

Remove `Engine`
It's just unnecessary plumbing. Removing it results in less code, and simpler code.

This is a standard pattern:
```
MyAnalysis.into_engine(tcx, body).iterate_to_fixpoint()
```
`into_engine` and `iterate_to_fixpoint` are always called in pairs, but
sometimes with a builder-style `pass_name` call between them. But a
builder-style interface is overkill here. This has been bugging me a for
a while.
This commit:
- Merges `Engine::new` and `Engine::iterate_to_fixpoint`. This removes
the need for `Engine` to have fields, leaving it as a trivial type
that the next commit will remove.
- Renames `Analysis::into_engine` as `Analysis::iterate_to_fixpoint`,
gives it an extra argument for the optional pass name, and makes it
call `Engine::iterate_to_fixpoint` instead of `Engine::new`.
This turns the pattern from above into this:
```
MyAnalysis.iterate_to_fixpoint(tcx, body, None)
```
which is shorter at every call site, and there's less plumbing required
to support it.

Deeply normalize `TypeTrace` when reporting type error in new solver
Normalize the values that come from the `TypeTrace` for various type mismatches.
Side-note: We can't normalize the `TypeError` itself bc it may come from instantiated binders, so it may reference values from within the probe...

Continue to get rid of `ty::Const::{try_}eval*`
This PR mostly does:
* Removes all of the `try_eval_*` and `eval_*` helpers from `ty::Const`, and replace their usages with `try_to_*`.
* Remove `ty::Const::eval`.
* Rename `ty::Const::normalize` to `ty::Const::normalize_internal`. This function is still used in the normalization code itself.
* Fix some weirdness around the `TransmuteFrom` goal.
I'm happy to split it out further; for example, I could probably land the first part which removes the helpers, or the changes to codegen which are more obvious than the changes to tools.

Remove `GenKillAnalysis`
There are two kinds of dataflow analysis in the compiler: `Analysis`, which is the basic kind, and `GenKillAnalysis`, which is a more specialized kind for gen/kill analyses that is intended as an optimization. However, it turns out that `GenKillAnalysis` is actually a pessimization! It's faster (and much simpler) to do all the gen/kill analyses via `Analysis`. This lets us remove `GenKillAnalysis`, and `GenKillSet`, and a few other things, and also merge `AnalysisDomain` into `Analysis`. The PR removes 500 lines of code and improves performance.

Use `ThinVec` for PredicateObligation storage
~~I noticed while profiling clippy on a project that a large amount of time is being spent allocating `Vec`s for `PredicateObligation`, and the `Vec`s are often quite small. This is an attempt to optimise this by using SmallVec to avoid heap allocations for these common small Vecs.~~
This PR turns all the `Vec<PredicateObligation>` into a single type alias while avoiding referring to `Vec` around it, then swaps the type over to `ThinVec<PredicateObligation>` and fixes the fallout. This also contains an implementation of `ThinVec::extract_if`, copied from `Vec::extract_if` and currently being upstreamed to https://github.com/Gankra/thin-vec/pull/66.
This leads to a small (0.2-0.7%) performance gain in the latest perf run.

To avoid some low-value boilerplate code.
|
|
With `GenKillAnalysis` gone, there is no need for them to be separate.
|
|
It's now functionally identical to `Analysis`.
|
|
Thanks to the previous couple of commits, many uses of the `GenKill`
trait can be replaced with a concrete type.
|
|
`GenKillAnalysis` has very similar methods to `Analysis`, but the first
two have a notable difference: the second argument is `&mut impl
GenKill<Self::Idx>` instead of `&mut Self::Domain`. But thanks to the
previous commit, this difference is no longer necessary.

stabilize `ci_rustc_if_unchanged_logic` test
Makes `ci_rustc_if_unchanged_logic` test more stable and re-enables it. Previously, it was expecting CI-rustc to be used all the time when there were no changes, which wasn’t always the case. Purpose of this test is making sure we don't use CI-rustc while there are changes in compiler and/or library, but we don't really need to cover cases where CI-rustc is not enabled.
Second commit was pushed for making a change in the compiler tree, so `ci_rustc_if_unchanged_logic` can be tested properly in merge CI.
