When called by reflection the bit mask will be generated
discounting dispatch/extension receivers. Make sure that the
interpretation of the bit mask is consistent for direct and
reflective calls.
In addition, this also fixes the modifiers on java 8 parameter
metadata for the dispatch and extension receivers for these
inline class methods.
1. Postpone the computation of the signature for property
reference getters for extension properties until codegen time.
2. Generate metadata for static replacement functions instead
of the original functions.
There are two parts in this change:
1) Previously, we looked up $default methods with the incorrect
signature in supertypes. For example in defaultInSuperClass.kt, we'd
try to find a method foo$default with the signature `(B, String,
String, int, Object)` in the class A. Now we're modifying the array
of parameter types on each step if we're looking for a static
$default method, by assigning its first element to be the containing
class. This fixes cases when defaults come from a superclass.
2) For interfaces, $default methods are actually located in the
corresponding DefaultImpls class. Now we look up that class and
search for the $default method there. Note that this is needed
because of KT-33430. This fixes cases when defaults come from a
superinterface.
#KT-13936 Fixed
Introduce MetadataSource as a way to store the original descriptor for
any element (before any lowerings) and maintain it until the end of the
codegen where it's used in generating the metadata. Note that JVM
signatures written to the metadata are formed from the _resulting_
generated elements, not by mapping the original descriptors.
Some corner cases are not supported yet, namely properties declared in
companion objects, synthetic methods for property annotations,
JvmPackageName, etc.
#KT-29119 Fixed
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)
The previous condition that checked if we'd skipped any optional
parameters didn't work when number of parameters > 32 because the number
of bit masks in that case was more than one
#KT-18404 Fixed
This patch mutes the following test categories:
* Tests with java dependencies (System class,
java stdlib, jvm-oriented annotations etc).
* Coroutines tests.
* Reflection tests.
* Tests with an inheritance from the standard
collections.
