as it may have no primary constructor (only actual class has it).
Refactor & rename Fir2IrGeneratorUtils.kt as having 'Fir' in stacktrace
when actual K2 compiler is not used is very confusing.
Fixes https://github.com/Kotlin/kotlinx.serialization/issues/2134
#KT-55683 Fixed
Name check was forgotten during refactoring, so any user function with
matching signature could be overwritten by the plugin, while correct
function would not have body.
#KT-55682 Fixed
of the class used in @UseSerializers: Use methods to receive
full list of supertypes.
K1 supertypes() call returned all supertypes, while
IrClass.supertypes and FirClassSymbol.resolvedSuperTypes return only immediate ones.
This lead to a difference in behavior between K1 and K2, and regression
after plugin backend was rewritten from descriptors to IR.
#KT-55340 Fixed
- IR plugin does not use it anymore,
regular annotation instantiation feature is used
(insertion of IrConstructorCall(annotationCtorSymbol)).
- IR plugin still generates `SerialInfo$Impl` class to be compatible
with previously compiled code & libraries.
- Custom implementation over descriptors in IR plugin is removed;
plugin now delegates to the existing lowering with some tweaks.
- $Impl descriptor is removed from FE 1.0 because it is no longer needed
for IR plugin; it shouldn't be exposed to users so FIR doesn't need it either.
- Since language lowering is now used, it is possible to correctly instantiate
SerialInfo annotations with default values even if they are from other modules
and even if they were not processed by the plugin.
#KT-48733 Fixed
Fixes https://github.com/Kotlin/kotlinx.serialization/issues/1574
#KT-54297 Fixed
Properly substitute surrogate UnitSerializer in the Companion.serializer()
function generated on classes that use polymorphic or sealed serializer
by default. (Fixes https://github.com/Kotlin/kotlinx.serialization/issues/1692)
Add intrinsic for kotlinx.serialization.serializer<T>() function.
Plugin intrinsic for old backend is removed because it is too hard
and unjustifiable to unify them.
