We generate @java.lang.Deprecated annotation on methods of $DefaultImpls
classes in compatibility mode. This annotation has RUNTIME retention and
should be visible.
Also, get rid of representing annotations as Class'es (yes we know that
these annotations are in compiler CLASSPATH, but we should not rely on
such classes and associated information).
There is no need to update type of delegate expression if it's already
resolved correctly (doesn't include non-proper types). In almost all
cases it was fine except number literals as there we didn't box
expression in backend and got problems at bytecode verification stage
#KT-40057 Fixed
In case of initializing property or function with anonymous object the
object is being exposed outside its field/function's scope and
accessible on previous level. In this case in `declarations only` mode
we have unbound symbols. Fix is to force body/initializer loading in
such cases.
Make sure it is deserialized in `declarations'only` mode too.
- Fix KT-40216
- Add test
Don't mangled functions annotated with @JvmName.
Annotate 'Result.success' and 'Result.failure' with @JvmName and
@Suppress("INAPPLICABLE_JVM_NAME").
NB this would require bootstrap.
There are multiple ways to declare a named variable-like entity in
Kotlin:
1. val/var variable declaration
2. destructuring declaration
3. parameter of a function
4. parameter of a lambda
5. destructured lambda parameter
6. for-loop's variable declaration
7. catch block exception declaration
8. val in when
9. field declaration
Out of them, only variable and field can be assignable, in other words,
they can be on the left hand side of an assignment.
Val/var variable declarations were already supported.
So, we needed to just support field initialization and tell the backend
that other ways are prohibited. Function and lambda parameters were
already been supported. So, the only thing to explain to the backend are
remaining ways.

For the same reason as in the previous commit: descriptors are cached
via weak references in moduleByClassLoader.kt and can be
garbage-collected at any point. So different instances of KParameterImpl
representing the same parameter may store different instances of
descriptors.
Descriptors are cached via weak references in moduleByClassLoader.kt and
can be garbage-collected at any point. So relying on identity of
descriptors in KTypeParameterImpl is dangerous because the same type
parameter can be represented by different descriptors. For example, the
test equalsOnFunctionParameters.kt was flaky before this change because
of this issue, and that could be reproduced by running it a few hundred
times in the same process.
Instead, use the type parameter's container (which is either KClass or
KCallable) and name, in equals/hashCode. KClass and KCallable already
have equals/hashCode independent of descriptors, so this works in case
the descriptor is invalidated.
- Allow participating subtypes of functional types in conversions
- Fix several subtle inconsistencies
- Place logic about conversions at one place
Now conversions operations have two stages: before usual subtyping
check and after one. This is needed to support conversions of
subtypes (of functional types, for example). First, the compiler
checks if it possible to resolve an argument without conversion and
only then it tries to perform conversion.
Note that it'd be incorrect to perform conversion eagerly as it can
change resolve (Runnable & () -> Unit <: KRunnable), plus we can't
guess whether conversion is needed at all as it's important not to
look into supertypes if resolution doesn't actually needed it
