- 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)
instead, plugins should emit the code similar to the TYPE_OF one with
a special call to MagicApiIntrinsics.voidMagicApiCall directly afterwards.
This is required because old compiler need to correctly inline code
rewritten by plugin.
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.
(Old is created first because all intrinsics emit bytecode anyway)
Provide intrinsic for serializer<T>() function so it won't
invoke typeOf() construction and KType->KSerializer conversion
making it fast and truly reflectionless
Add support for recalculating stack size in plugin-defined intrinsics
since it is needed for correct work:
Unify method for recalculating stack size with existing typeOf intrinsic
Add testdata for IR for future intrinsic in IR
