After the previous commit, IC does not recompile code related to CLI
arguments parsing (likely due to KT-57919), so the resulting dist
compiler doesn't work at all, and all related tests are failing. This
"useless" override tricks the IC to recompile the class and all its
subclasses.
The command line argument parser is using between 0.25s and 0.5s
(depending on platform) on finding annotated properties. This fix
replaces the slow kotlin reflection with java reflection, which is an
order of magnitude faster.
#KT-58183 Fixed
It acts as a workaround for the case when build tools or dependencies
are compiled with latest 'kotlin-stdlib' version, but at a runtime older
'kotlin-stdlib' is provided, which does not know about new
`EnumEntries`.
^KT-57317 Fixed
The patch adopts and reuses the optimizations from the legacy backend.
The optimizations remove useless temporary variables,
statements and simplify generated JS code.
The optimizations can be disabled by `-Xoptimize-generated-js=false`.

Using of Kotlin reflection for simple operations like bean management is very slow
First time initialization time: 261 ms for `copyBean(K2JVMCompilerArguments())`
Subsequent calls of `copyBean(K2JVMCompilerArguments())` take 1.7 ms per call
Unfortunately compiler argument handling is also used in Kotlin IntelliJ plugin
to parse facet settings. Big projects may have thousands of Kotlin facets
The same `ArgumentUtilsKt.copyProperties` frame is seen across various freezes:
IDEA-252440 2-3 minutes freeze on Kotlin project reimporting in last 203 eap
IDEA-253107 A lot of short freezes (1-3 sec) during Kotlin project development
KTIJ-23501 Make main run configuration detection lighter
KTIJ-22435 Unresponsive UI with 100% cpu
Reflection issue:
KT-56358 KClasses.getMemberProperties takes too much time
This commit replaces all reflection stuff with a simple code generation
Now `K2JVMCompilerArguments().clone()` goes to hard-to-measure time
This parameter accepts the name of the "mode" in which the partial linkage would work. Currently, only two options are supported: 'enable', 'disable'. But the list may be extended in the future as needed.
At the moment the 'disable' option is the default one. This will be changed in #KT-51447, #KT-51443.
This is a low-level extension point for Kotlin/JVM, which is supposed to
be used instead of ClassBuilderInterceptorExtension.
#KT-54758 Fixed
#KT-56814 Fixed
This is required to be able to compile KGP and it's dependencies which
set LV to 1.4 when repo will use LV 1.9. This caused by the change how
enums are compiled (KT-48872).
