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".
#KT-43592
The problem is that JvmRecord has SOURCE retention
Probably, increasing its retention might be a more reliable solution
(or in some other way serializing that the class is a record)
Just checking supertypes seems like a reasonable approximation:
only records kotlin are allowed to extend j.l.Record.
But the relevant diagnostic has been added only since 1.4.30,
so potentially there could have been exist a non-record class with
such supertype compiled by 1.4.20, but this case seems to be ill-formed
and marginal anyway.
For Java classes, it's irrelevant since they don't have member properties
(only synthetic extensions)
^KT-43677 In Progress
If we do, the local variable table will not make sense. As as
example:
```
inline fun foo(getString: () -> String = { "OK" }) {
println(getString())
}
inline fun bar() {
}
fun main() {
bar()
foo()
}
```
leads to the following bytecode:
```
public static final void main();
descriptor: ()V
flags: ACC_PUBLIC, ACC_STATIC, ACC_FINAL
Code:
stack=2, locals=4, args_size=0
0: iconst_0
1: istore_0
2: nop
3: nop
4: iconst_0
5: istore_1
6: nop
7: ldc #53 // String OK
9: astore_2
10: iconst_0
11: istore_3
12: getstatic #30 // Field java/lang/System.out:Ljava/io/PrintStream;
15: aload_2
16: invokevirtual #36 // Method java/io/PrintStream.println:(Ljava/lang/Object;)V
19: nop
20: return

LocalVariableTable:
Start Length Slot Name Signature
2 1 0 $i$f$bar I
6 14 1 $i$f$foo I
4 16 0 getString$iv Lkotlin/jvm/functions/Function0;
```
The `getString$iv` local should not be there. It has been inlined away.
Leaving it in the local variable table leads to inconsistent locals
info. Local 0 contains an int but we declare a local of type
Function0.
if it is called using parens and not by calling 'invoke' method.
Use underlying type when calling continuation constructor if suspend
function is method inside inline class.
