Given the strict pattern-matching in the inliner, this is the only way
to make it not crash when attempting to inline these stubs. Note that
the IR backend does not currently use the inliner's default method stub
handling; the crash only occurs when a module compiled with the non-IR
JVM backend is attempting to call an inline function with default
arguments defined in a module that was compiled with the IR backend.
If "null" was the first entry in an optimizable "when" over enum,
mapRuntimeEnumEntry was called before mapConstEnumEntry, and the
$WhenMappings field was not created. Now both mapConstEnumEntry and
mapRuntimeEnumEntry create this field on the first access
other than randomly throw assertion errors on inline calls in synthetic
functions, which have no line number attached.
`lazySourceMapper.callSiteMarker` is set in `InlineCodegen.inlineCall`;
`IrSourceCompilerForInline.doCreateMethodNodeFromSource` does not need
to touch it.
Function return type can't and should not be used during overload resolution of callable references.
Since it can be DeferredType, its substitution in CS caused exception.
The challenge for overridable suspend functions is that the calling
the state machine method to resume after suspension would be
virtually dispatced to the wrong method. To avoid that a static
suspend implementation method is generated which becomes the
state machine method used to resume.
UL classes built upon descriptors and UL support classes are saving a descriptors.
This could lead to descriptors leakage so we have to eliminate any fields with descriptor references.
Fixed #KT-34337
NOTE: jvmCrossinlineLambdaDeclarationSite.kt is muted because the
inliner does not remap references to an anonymous object's parent
class after regenerating it. Unlike the JVM backend, JVM_IR uses the
top level named class' assertion status for all inner classes. (The
test used to pass because the lambda in `inline fun call` read the
`$assertionsDisabled` field of `CrossinlineLambdaContainer`, which
was not reloaded after changing the assertion status of package `test`.)
It is required when enum members contain some special annotations which should be recorded in descriptor.
Due to some recursive/lazy resolve problems, compiler plugin frontend can't infer @Serializable on enum automatically, therefore, we ask a user to explicitly provide it.
Also fix ir tests
