Generate continuation type as kotlin.coroutines.Continuaion. This code will
fail at runtime since there is no stdlib backing this change yet.
However, in order to generate compatible stdlib we need a compiler, which
generates continuation type as kotlin.coroutines.Continuation.
Thus, firstly we support the change in the compiler, make it bootstrap
compiler and only then change stdlib and tests accordingly.
#KT-23362
Private suspend functions need to be generated as package-local, since
they are called from their continuations.
However, this means that they can be called from Java, which breaks
their private visibility.
Adding synthetic to them fixes the issue.
#KT-17584: Fixed
Sometimes instead of {POP, GETSTATIC Unit.INSTANCE, ARETURN} sequence
the codegen emits {CHECKCAST Unit, ARETURN} sequence, which breaks tail
call optimization. By replacing CHECKCAST with ARETURN we eliminate
this issue.
#KT-19790: Fixed
Design decision: if the field for a companion object should have
non-public visibility, generate it with @Deprecated annotation in
language version 1.2.
TODO: generate it with proper visibility in 1.3 and later.
KT-11567 Companion object INSTANCE field more visible than companion object class itself
These changes has been introduced in c3a032ea0b
to support new scheme for named functions
At the same time they can be avoided by generating some additional
code/accessors in the anonymous classes for coroutine state
Now we cannot simply remove introduced API because of bootstrap problems
#KT-17898 Fixed
The main idea is to leave all the inline functions as is, without
state machines (but keeping suspend-calls markers) and
determine whether we need a state machine from the bytecode
after inlining into a non-inline function
#KT-17585 In Progress
#KT-16603 In Progress
#KT-16448 Fixed
Since annotations are a part of the declaration, they must have the same
visibility as the declaration in the bytecode. Otherwise obfuscators like
Proguard might strip the "$annotations" method and no annotations would be
found via Kotlin reflection
#KT-15993 Fixed
Otherwise it breaks JPS assumptions, that leads to exceptions like:
Error:Kotlin: [Internal Error] java.lang.AssertionError: Couldn't load KotlinClass from /Users/jetbrains/IdeaProjects/KotlinPlaygroundBeta11/out/production/KotlinPlaygroundBeta11/Counter$both$1.class; it may happen because class doesn't have valid Kotlin annotations

- `invoke` method must always start a suspend functions
- For creation of coroutine that has not been started yet, there are
two special internal interfaces `SuspendFunction0`/`SuspendFunction1`
Fixed KT-14939: use expected receiver type when generating receiver code in get/set methods for bound property references.
Otherwise we have VerifyError for bound receiver 'null' of type 'Nothing?', which is mapped to 'java.lang.Void'.
TODO: proper equality comparison for property accessors ('x::prop.getter', 'x::prop.setter').
