It is easier to introduce a new lowering so the codegen will emit code for the old
tail-call optimizer to understand. Also, this is more flexible and would allow to
optimize cases, which are now feasible with the old optimizer.
Note, that because of bytecode inlining, we cannot replace the old one, but we cannot
emit code, that is simpler for it to optimize.
Since the markers replace ALOAD 0 as continuations, passed to suspend calls, in
JVM_IR we do not need this, since in JVM_IR all inline lambdas are static
functions.
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.
kotlinx.serialization plugin now adds additional function to companions
of generic classes in order to overcome lack of reflection. This
helps retrieving generic serializers from KType.
An uninferred parameter stub may leak through calculation of CST(Inv<Uninferred Stub>, Nothing) into a result type.
A stub type in the result type means a type error. So we can afford recalculating
CST with stub-containing types filtered out, since its an error anyway.
This prevents stub types leakages and helps with reporting type error diagnostics.

Inline functions require Kotlin compiler at least 1.3.50 if they were
generated by the compiler with API version >= 1.4. This is because since
API version 1.4, we've changed the generation scheme of parameter
nullability assertions and they now refer to methods from the standard
library which did not exist until 1.4. See
JvmSerializerExtension.writeInlineParameterNullCheckRequirement.
Since 1.4, constant value is no longer written to the class file (and
thus cannot be read) for non-const properties. But in sources,
corresponding property descriptors still have the initializer which is
rendered to text. Therefore we disable the source-vs-binary check and
update the test data to check the new behavior.
The Android build pipeline can extract embedded proguard configurations
from dependencies and merge them automatically. This adds a conservative
proguard configuration to the kotlin-reflect JVM artifact in support of
that. This focuses mostly on just retaining what's necessary for
kotlin-reflect's own functionality to operate, but could be expanded if
community feedback discovers other good candidate rules.
With this in place - most Android projects using R8 or Proguard should
Just Work™️ with kotlin-reflect.
