The problem was that in K2 for some top-level script declarations we
need to add a dispatch receiver parameter (because frontend do not
assign any, but representing script as a class requires it to be the
script class) and at the same time, calls to these declarations rely on
properly set dispatch receiver parameter.
The simplest solution found is to have an additional traversal on the
relevan top-level declarations and assigning the dispatch receiver,
before running the main transformation.
#KT-64502 fixed
namely, add them to importing scopes directly and according to the
schema used for other implicit imports, rather than adding them
to the regular script file imports. See KT-65982 for explanation.
#KT-65982 fixed
The base class in scripting considered obsolete and therefore supported
via some ad-hoc mechanisms. In particular parameters to the base class
c-tor are passed via script provided properties. But in combination
with the resolution logic, this leads to issues described in KT-60452
This commits filters out such parameters from script resolution
scope and avoids this problem for now.
Bot it should be noted that proper diagnostics for properties shadowing
should still be implemented - see #KT-65809

`IrProvider`s are used to bind unbound symbols which are left after IR
construction. fir2ir doesn't leave any unbound symbols in the tree,
so there is actually no need in FirIrProvider at all
Here is the reasoning behind that change:
Historically, all the declarations generated by compiler plugins
were marked with `SYNTHESIZED` member kind in Kotlin Metadata
by K1 compiler.
In K1 IDE, descriptors were deserialized directly from the Kotlin
Metadata, and they saw all the generated declarations from it.
In the stubs, however, such declarations were not materialized at all.
It caused no troubles, since K1 IDE relied on descriptors to get the
essential resolution information in completion and other subsystems.
So, the resolution of members from jars processed
by compiler plugins (e.g. `kotlinx-serialization-json`) was mostly fine.
In K2 IDE, however, we use stubs to "deserialize" FIR declarations from
them, to later create `KtSymbol`s upon that FIR.
If we see a library file which was processed by compiler plugins, we
build stubs for it based on the Kotlin Metadata, and then use stubs to
create FIR.
But if stubs do not contain information about the generated
declarations,
then the resulting FIR will also not contain such declarations.
In the end, the K2 IDE would also be blind to such declarations, since
there is no other way to retrieve them from the library jar.
By meterializing all the synthethic declarations in stubs (with some
minor exceptions for data classes), we would avoid such problems,
and the resolve of such declarations from compiler jars in
K2 IDE would become possible.
Important note: currently, the Kotlin Metadata format between K1 and K2
frontends is not 100% the same; most notably, in K2, the generated
declarations are marked as regular declarations,
not as `SYNTHESIZED` ones.
Hence, if you compile a jar with the current version of K2 frontend,
then all the generated declarations would have a regular `DECLARATION`
origin, and there would be no such issues as described above.
There are two notes here:
1. K2 IDE still has to support the jars compiled by the K1 compiler,
so it still makes sense to alter the stubs and make the generated
declarations visible.
2. The issue about the different stub formats has been reported
(see KT-64924), and might be resolved in the future.
So it is possible that K2 frontend's metadata will also start
marking the generated declarations as `SYNTHESIZED`.

It should have been already implemented as intrinsic in all backends.
Do not test enumEntries intrinsic in the old JVM BE.

When using DeepCopyIrTreeWithSymbols as class transformer to transform
the IrClass, the source element of IrClass was set to
SourceElement.NO_SOURCE after the transform.

Before this commit, the expect-actual resolver could find expects in
regular dependencies
Note: The appeared `VIRTUAL_MEMBER_HIDDEN` in
compiler/fir/analysis-tests/testData/resolveWithStdlib/multiModule/FakeOverrides.kt
isn't caused by my change. It's caused by fixing the testData dependency
syntax notation.
The testData improperly used regular dependency syntax notation, while
it should have been using dependsOn
Before:
Regular dependency syntax notation
// MODULE: androidMain(commonMain)
After:
dependsOn dependency syntax notation
// MODULE: androidMain()()(commonMain)
`originalCallee` is supposed to be the owner of the original call.
It can be a fake override, and in the inliner we are using actual
function with body. Apparently we can just stick with the resolved
function.

The previous one was incorrect for K1 since parent of top-level function
is `IrClass`, not `IrPackageFragment`.
The change is non-functional, K1 still worked correctly, but had to do
some extra work when inlining `emptyArray` calls and produces less
performant bytecode.
It was a workaround for case, where expect class don't have
override of abstract function. We don't allow it anymore,
so it can be dropped to make correct modality comparation.

This fixes some crashes on red code in diagnostic tests.
Also can be useful in the future, when we would allow things like
enum.name in annotation arguments.

Otherwise, when analyzing
`PsiTypeParameterListOwner` in the
related test, we (after flattening and
`nonSubsumed()`) get 2 `JvmMember.accept`
from the same very java enhancement
scope `JvmMember`.
