#KT-35740 fixed
also add tests and drop logger usage in the cli dependencies manager:
the logger is normally unitialized in the usage scenarios, but related
warnings are annoying.
suspend lambda.
The Name for the special destructuring declaration parameter was
incorrectly turned into a regular/non-special Name when the parameter
was moved to a field.
AbstractCheckLocalVariablesTableTest and fix
`checkLocalVariablesTable/localFun.kt` for JVM IR.
Also improved diagnosability of CheckLocalVariablesTableTest failures.
FAKE_OWNER is a hack for when we encounter IrFunctions with non-class
parents during codegen. This can only happen for unhandled intrinsic
functions and resolving them to FAKE_OWNER can cause codegen to succeed
while producing broken bytecode.
There are two array intrinsics which are handled in the inliner on the
JVM backend: arrayOf and emptyArray. In the IR backend we are already
lowering arrayOf as part of VarargLowering and this commit adds support
for lowering emptyArray as well.
interface I {
fun f(x: Int = 1)
}
class C(val y: I) : I by y {
// implicit `override fun f(x: Int) = y.f(x)` has a default value for `x`
}
-- the only case where a function with overridden symbols has defaults.
1. Postpone the computation of the signature for property
reference getters for extension properties until codegen time.
2. Generate metadata for static replacement functions instead
of the original functions.
It uses the same logic as an old back-end
(see SamType#createByValueParameter and genericSamProjectedOut.kt),
split into two parts:
1. When inserting SAM casts, use SamType#createByValueParamerer to get
the target SAM type.
2. When inserting implicit casts, cast SAM conversions as arguments of
methods of out-projected types to the original type of value parameter
instead of 'Nothing'.
Consider the following example:
Java:
public class J {
public static String foo() { return null; }
}
Kotlin:
fun check(fn: () -> Any) = fn()
fun test() = check { J.foo() }
When a lambda expression returns a value of platform type ('String!'),
corresponding lambda has platform type in its return type, which is
approximated to corresponding nullable type ('String?') in IR.
However, the lambda itself could occur in position with a functional
expected type ('() -> Any'). This implies an extra implicit cast on a
return value of lambda expression ('J.foo()'), although it conforms to
the return type of lambda.
When generating bodies for members implemented by delegation, invoke
corresponding delegate member, not an interface member. Otherwise we
might lose platform-specific nullability information in case of mixed
Kotlin-Java hierarchies, as in
implicitNotNullOnDelegatedImplementation.kt
When calling a generic Java generic method with vararg parameters with empty
vararg, incorrect array creation instruction was generated for primitive type:
NEWARRAY T_INT instead of ANEWARRAY java/lang/Integer. Here for Java method
public static <T> void takesVarargOfT(T x1, T... xs) {}
corresponding vararg parameter was considered to be of type 'Array<T>?',
which is not a non-null array type, so, NewArray intrinsic failed to generate
proper bytecode.
- Exclusion happens only when `ReleaseCoroutines` feature is supported
- Add `LANGUAGE_VERSION` to few tests to make sure that previous exclusions still work when `experimental` package is not excluded entirely
