The number of initializations of the `value` field before the live range
begins does not really matter so long as we insert a write of a default
value to the local if there were none.
See KT-36812. Aside from the problem stated there, D8 will throw out the
entire LVT if it sees a variable that has not been written to (and will
generate incorrect SSA if the slot is reused with a different type).
Note: this only fixes a FIR test because it's missing an `else -> throw`
branch, and default initialization satisfies the verifier and masks the
incorrect control flow.
We always set the $assertionsDisabled field based on the top-level
enclosing class. This means that for anonymous objects we have to
rewrite the call to Class.desiredAssertionStatus.
values within initializer blocks.
The issue occurs in code like this:
```
class C {
var b = true
init {
b = false // Missing PUTFIELD for this statement
}
}
```
Added a new statement origin for field initialization (at declaration)
instead of relying on `origin == null` in ExpressionCodegen to determine
whether to generate the initializations.
This was unintentionally broken in
d68a1898d0.
If a part of an 'if' condition is an inline function call, we need to insert the original condition line after it. Otherwise, the debugger will think it is inside the inline function implementation. Obviously, this breaks stepping – instead of the 'if' body, we go on stepping through the inline function.
This commit fixes 'KotlinSteppingTestGenerated.StepOver#testSoInlineLibFun' test.
This commit fixes the following tests:
- KotlinSteppingTestGenerated.StepOver#testSoInlineLibFun
- KotlinSteppingTestGenerated.StepOver#testSoInlineIterableFun
- KotlinSteppingTestGenerated.StepOver#testSoInlineFunOnOneLineFor
- Uncomment tests
- Add proper visibility to companion field
+ Make exception for interfaces -> they need to respect language versions 1.8
before they can put private members there.
- Adjust synthetic accessor lowering to look for enclosing classes with access
via companion object.
backends by removing IMPLICIT_NOTNULL casts from IrStringConcatenation
arguments.
Also fixed an issue where IrStringConcatenation can be lowered into
a null String instead of a literal "null" String if the lone argument
was a platform type String or String with enhanced nullability and the
value was null (e.g., "${FromJava.nullPlatformString()}").
Don't insert implicit null check on a value of @EnhancedNullability type
used where @EnhancedNullability type is expected.
This uncovers a bunch of other problems in FE and BE.
KT-36343 and KT-36347 are bugs in StrictJavaNullabilityAssertions
implementation which should most likely be fixed in next major language
version (with proper breaking change notice).
KT-36344 is a design problem which should be addressed after 1.4 issues
are resolved.
Final default properties accessors that access a backing field
on the same class can be replaced by direct field use.
Perform the optimization late in the pipeline to allow lowerings
to expose more opportunities for optimizations.

Do not check for occurrences of "this" on the current backend.
I accidentally unified the checking for the two backends
without checking that it worked (used the wrong test suite to
test).
The first change here is swapping the isCompatibility and hasJvmDefault
checks. Otherwise behavior could be different depending on -Xjvm-default
mode even for non-JvmDefault declarations, which makes little sense.
Another change is avoiding generating $default stubs for fake overrides
in interfaces, which replicates the behavior of the current backend.
(Note that this change also fixes the first problem on the newly added
tests, but the first change seems useful anyway.)
