The generated code is more inline with java, and we avoid the error of
accessing package-private field outside of the package.
However, this changes semantics a bit. Now, a user should set assertion
status of inline-site's package, instead of inline function's one.
#KT-28317: Fixed
The root problem is the fact that ConstantExpressionEvaluator returns
null for values such as infinity and NaN loaded from cls psi (see
IDEA-207252). This commit simply reverts a part of 8ab9226805 where we
started to compute default values more often than needed. In
LazyJavaClassMemberScope, we only need to check whether or not there
_is_ a default value, not compute its value.
#KT-29792 Fixed
Split the ConstAndJvmFieldPropertiesLowering into two: ConstLowering
which replaces const vals with their values, and
PropertiesToFieldsLowering which removes unnecessary property accessors
(such as for JvmField or private properties with default accessors) and
replaces calls to those accessors with field access
The boundWithSerializableReceiver.kt test is muted since property
references are not yet supported in the JVM IR backend. Previously it
passed by accident
In InnerClassesLowering, the type of the "outer$0" expression should be
the outer class, not the inner class. In EnumClassLowering, the type of
the enum entry is the type of its class or the type of the enum class,
but not the type of initialierExpression which is always Unit
IrDeclarationOrigin.FILE_CLASS is used in CallableReferenceLowering to
generate correct declaration owner.
Many reflection tests start to fail with this commit because they are
now treating callable references to top level declarations as Kotlin
symbols and fail because there's no JVM signature for them; this is
fixed in subsequent commits (previously, they worked because without
Kotlin metadata, these files were treated as Java classes)
Code such as
```
val b = getBoolean()
if (b) 4
else if (b) 5
```
didn't generate a value on the stack always and therefore would
have control-flow paths leading to a pop instruction with nothing
on the stack.

Initializers are "set field" expressions and are considered redundant
when they are:
1. In the primary constructor; and
2. Set the field to `0`, `false`, or `null`; and
3. Have a `null` origin. I.e., not in an initializer block or
constructor body, and therefore the field could not have been set by a
prior expression.
Simplify MultifileClassPartCodegen, remove related tests and change some
tests to use const val instead of val because backing fields for const
properties are stored in the facade, not parts
#KT-23701 Fixed
In JDK 9, Class.simpleName changed behavior for local/anonymous Kotlin
classes (see KT-23072), this is why we now check for both variants of
the name in tests. Also, the format of annotation arguments changed a
little, where float parameters no longer have the trailing "f", and
class literals are rendered with ".class" at the end
Simplify ifs when branches have condition true/false.
Simplify blocks containing only a variable declaration
and a variable get of the same variable. Simplify to
just the condition.
Do not introduce temporary variables for constants for
null checks. Constants have no side-effects and can be
reloaded freely instead of going through a local.
This simplifies code such as "42.toLong()!!" so that the
resulting code has no branches and uses no locals. The
simplifications happen as follows:
```
block
temp = 42.toLong()
when
(temp == null) throw NPE
(true) load temp
---> null test simplification
block
temp = 42.toLong()
when
(false) throw NPE
(true) load temp
---> when simplification
block
temp = 42.toLong()
load temp
---> block simplification
42.toLong()
```
In case of the same class defined in different modules they contain
different descriptors instances in their scope that might lead
to failing assertion in findConcreteSuperDeclaration
because there are overridden from different modules
It might happen even in the compiler because of different built-in modules
defined for sources-module and for dependencies' one
