CirConversions did not cover some potential convertible types.
ClassOrTypeAliasTypeCommonizer did not apply type substitution
for parameterized types coming from a dependency
^KT-48288
This commit still has some left-over todos that shall be done
in a separate commit.
TODOs:
- CirClassifierIndex is calculated once too often
- Reconsider position of classifierIndices in 'CirKnownClassifiers'
- Add documentation/description to complicated 'ClassSuperTypeCommonizer'
- Add documentation/description to CirSupertypesResolver
^KT-47430 Verification Pending
^KT-47574 The fix done here supports only one level of substituting
underlying type-arguments.
HierarchicalTypeAliasCommonizationTest.`KT-47574 - test long typealias chain`
will assert proper behaviour for nested chains.
Those assertions are not necessary anymore, since the commonizer is not
expected to produce any new "actuals" per given expect.
The IDE is supposed to analyze leaf source sets against the original
platform libraries.
- Reduce usage of 'isUnderStandardKotlinPackages' check in commonizer source code
- Rely on common module dependencies supplied via commonizer Parameters which not only
Kotlin standard library but may also include common fragments of other libraries
1. Drop CirClassifierId
2. Specialized classes for each kind of types (classes, TAs, type parameters, flexible types).
3. TypeCommonizer now returns commonized type. In case of TAs this could be a completely new type
describing expect class or a new TA with the different underlying type.
