If an inline class is mapped to a reference type (or an array), it's Ok
to treat JVM view on a suspend function as returning a value of
corresponding inline class (although in reality it returns 'Any?'
because of COROUTINE_SUSPENDED).
We can only use IrStrinConcatentation to represent calls to Any?.toString
and toString calls on primitive types. Otherwise, x.toString() and "$x"
are observably different when x is a non-null type with null value
(e.g., an @NotNull value coming from Java).
Added creation and initialization of the test module and its dependencies.
When looking at the emptyProgression test,
I found that getProgressionLastElement was not found,
which should be resolved from the dependencies.
Without this commit, JVM name mapping logic in BE does not work for FIR,
because FIR cannot use old BuiltInsPackageFragmentImpl descriptor.
In this commit we add our own implementation thus fixing
a pack of FIR black box tests.
even when arguments are to be rearranged.
Lambdas have no side effects, and storing them in temporary variables
prevents processing in the backend
(such as inserting continuation parameter in AddContinuationLowering).
The fields containing crossinline lambdas should be package-private to
avoid generating synthetic accessors, which break object regeneration.
Note that the inline methods cannot actually be called, as call sites
will attempt to read the captured lambda from a field through a *copy*
of the local containing the object, so these reads will not be inlined,
causing an exception at runtime:
inline fun f(crossinline g: () -> Unit) = object : I {
inline fun h() = g()
// effectively `val tmp = this; return tmp.$g()`:
override fun run() = h()
}
f {}.run() // NoSuchFieldError: $g
This particular example can be fixed by reusing locals for receiver
parameters in IrInlineCodegen, but explicitly assigning `this` to
another variable and calling an inline method on it will break it again.
(This is only applicable to the JVM_IR backend, as the non-IR one fails
to generate `f` at all for some other reason.)
1. Search for increment function in range element type, not in inferred
induction variable type
(which can be inappropriate, e.g., 'Nothing' in case of 'continue').
2. Handle nested loops with shared exit labels
(generated by JVM_IR for KT-37370 case).

- Since neither IrProperty nor IrField is Type Parameter container
using of proprty's type parameter in IrField related code leads to
creation of "hanging" type parameters which should be considered as
incorrect IR.
- Such code designed to be prohibited in LV 1.5
- The fix makes use of erased type in such case
where type parameter is expected.
Now FE IR -> BE IR transformation is performed in multiple stages
controller by Fir2IrConverter. Stages are
* files & classes registration
* supertypes & type parameters handling
* functions & properties signature generation
* body generation
After each step we have guarantee (with exception of local classes &
type inference combination, and external symbols) that required symbols
(class/function/property/variable/type parameter)
are already bound to real declarations and have correct parents.
This commit also fixes incorrect parents for local classes
In case derived class has a field with the same name as the base class,
RenameFieldsLowering previously tried to rename one of the fields by
adding the "...$1" suffix, which led to NoSuchFieldError.
