2023-07-12Create and cache flattened inheritance lists (#2740)Theresa Foley
* Create and cache flattened inheritance lists The basic change here is to have a cached lookup that can map a `Type`, or a `DeclRef` that might refer to a type or `extension`, to a list of the *facets* that comprise it. The notion of a *facet* here is similar to what the C++ standard calls "sub-objects". A declared type like a `struct` has: * a facet for its own direct members * one facet for each of its (transitive) base `struct` types * one facet for each `interface` it conforms to * one facet for each `extension` that applies to that type The set of facets for a type is de-duplicated (so that "diamond" inheritance patterns don't cause issues) and deterministically ordered, using a variation of the C3 linearization algorithm. The creation of a linearized list of facets should help the compiler implementation in two key places: * Testing if a type implements an interface (or inherits from a base type) should now only take time linear in the number of (transitive) bases of that type. We can simply scan the linearized facet list to see if it contains a facet corresponding to the given base. * Looking up the members of a type (or a value of a given type) should be greatly simplified, since all of the members can be found in a single linear scan of the facet list. In addition, those facets will be ordered so that facets for "more derived" types will precede those for "less derived" types, so that shadowing in the case of overrides should be easier to implement. This change only implements the first of these two improvements, since there is already a *lot* of churn involved. Notes and caveats: * The handling of conjunction types (e.g., `IFoo & IBar`) complicates the implementation, both because the simple approach to subtype testing alluded to above is no longer complete, and also because we need to be more careful about what forms of subtype witnesses we construct, so that we can maintain the currently-required invariant that two witnesses are only equal if they have matching structure. * We don't implement the full/"proper" C3 algorithm here because it has some failure cases that we'd still like to support. In particular if we have both `IX : IA, IB` and `IY : IB, IA`, the C3 algorithm says it is illegal to have `IZ : IX, IY` because the two bases it inherits from disagree on the relative ordering of `IA` and `IB` in their own linearizations. Handling such cases may make our implementation less efficient, and it will also require testing of those corner caes. * When it comes time to revamp the implementation of lookup, we will need to deal with the fact that a single linear list (seemingly) cannot give us sufficient information to decide which of two members of the same name should shadow the other, or if there is an ambiguity. Or rather, it *can* give us that information if we are willing to accept some very user-unfriendly behavior and simply say that declarations earlier in the linearization always shadow later declarations, even if the facets involved are not related by an inheritance relationship of any kind. * In order to remove one kind of vicious circularity from the approach, the linearization that we are computing for `extension` declarations will not be sufficient for lookups in the body of such an `extension`. A future change may need to have support for creating and caching two distinct linearizations for each `extension`: one that is to be used when that `extension` is pulled into the linearization for a type that it applies to, and another for when lookup will be performed in the context of the `extension` itself. * This change does *not* include the simple expedient of adding a direct cache for subtype tests to the `SharedSemanticsContext`, although adding such a cache would be a simple matter. * This change introduces more deduplication for subtype witnesses, which should enable more deduplication for other `Val`s (including `Type`s), but it does not introduce any assumptions that equal `Val`s or `Type`s must have identical pointer representations. * Eventually we may find that, similar to the situation with `Type`s, we will want to have a split between surface-level and canonicalized versions of other `Val`s, including subtype witnesses. * Fix clang error. * remove debugging code. --------- Co-authored-by: Yong He <yonghe@outlook.com>
