Pass parentContext to SamWrapperCodegen from the outside instead of
using the one from parentCodegen. The difference is that in case of an
inline lambda, we're creating an InlineLambdaContext whose parent is a
ClosureContext, but the codegen for that lambda has that latter
ClosureContext as its context. So the getNonInlineOuterContext call in
SamWrapperCodegen.generateInnerClassInformation wasn't able to identify
that this is a context of a lambda that needs to be skipped, and
generated it as EnclosingMethod, which caused Java reflection to fail
because once that lambda was inlined, it was removed and thus didn't
make it to runtime.

These utilties are used not only within CFG, but from the frontend and
idea as well. Therefore upon extraction of CFG into another module,
these two new files will remain in 'frontend'.
Improve the test which checks that we use correct metadata version if
`-language-version` is passed by checking all supported language
versions.
The change in libraries/reflect/build.gradle.kts is needed because
kotlinx-metadata-jvm of version 0.1.0 is based on pre-1.4 Kotlin, which
doesn't support the new module file metadata generated with metadata
version 1.4 and later, and module files need to be readable there to be
able to transform them for the shadow plugin.
Similarly override dependency on kotlinx-metadata-jvm in the
binary-compatibility-validator module.
In the old backend, this was unnecessary because nested objects would
reference their lambdas' captures through the original this$0. On
JVM_IR, using loose capture fields means a name/descriptor clash can
occur on any level of nesting, not just the top.
i.e. remove the condition that there must be an LVT entry. Such
temporary `Ref`s can be created, for example, by the JVM_IR backend
if a lambda inlined at an IR level (e.g. argument to `assert`/`Array`)
is the target of a non-local return from a function inlined at bytecode
level (e.g. `run`):
IntArray(n) { i ->
intOrNull?.let { return@IntArray it }
someInt
}
->
val `tmp$0` = IntArray(n)
for (i in 0 until `tmp$0`.size) {
var `tmp$1`: Int
do {
intOrNull?.let {
`tmp$1` = it // causes `tmp$1` to become an IntRef
break
}
`tmp$1` = someInt
} while (false)
`tmp$0`[i] = `tmp$1`
}
Not in the frontend or psi2ir, though, so this not a complete
implementation of KT-1436, but rather a part of it that is currently
useful to make other code compile. In particular, lambdas passed to
array constructors and JVM-style `assert` are inlined as IR returnable
blocks, which are then converted into `do { ... } while (false)` loops,
so non-local returns from them become non-local `break`s.
This fixes some tests for LV=1.5 in KotlinJpsBuildTest,
KotlinJpsBuildTestIncremental, IncrementalJvmJpsTestGenerated,
IncrementalCacheVersionChangedTestGenerated.
#KT-42069 Fixed
This is a hack to work around the fact that type mappings should not be
inherited by inlining contexts for lambdas called from anonymous
objects. As the lambda can call the inline function again, this could
produce a reference to the original object, which is remapped to a new
type in the parent context. Unfortunately, there are many redundant
`MethodRemapper`s between the lambda and the class file, so simply
editing `TypeRemapper` does not work. Hence, this hack. For now.
(Issue found by compiling IntelliJ IDEA BTW.)
This flag was added a long time ago, at the time when we weren't sure if
we were going to keep the naming of local and anonymous classes
completely equal to the naming in the old backend. Now that we've
decided that we won't keep it equal and there are a lot of differences
already, it's not useful anymore.
Use {de,}capitalizeAsciiOnly and to{Lower,Upper}CaseAsciiOnly where
possible, and stdlib's functions with Locale.US everywhere else.
Otherwise, if the default system locale is Turkish, the capital latin
letter "I" is transformed in toLowerCase to "ı" (see
https://github.com/JetBrains/kotlin/blob/66bc142f92085047a1ca64f9a291f0496e33dd98/libraries/stdlib/jvm/test/text/StringJVMTest.kt#L119),
which for example breaks the codegen for `intArrayOf` in
KT-25400/KT-43405.
Similarly, lower case latin letter "i" is transformed to "İ".

Introduce an enum DeserializedContainerAbiStability with two values.
This is needed in order to support another reason for ABI instability in
a subsequent commit, namely "unstable because compiled by FIR".
