This commit fixes two issues in the existing implementation of translating primitive array types:
* IrType.getArrayElementType throws an exception when the receiver is a primitive array type, because IR expects primitive array types use symbols defined in IrBuiltIns, but fir2ir translation doesn't;
* IteratorNext.toCallable assumes all element types are boxed.
The first issue is fixed by changing the fir2ir type translation to use symbols in IrBuiltIns for primitive array types, and the second by not unboxing primitive types.
We get the info for the underlying progression and invert it. For
progressions whose last bound was open (e.g., `until` loop), the
reversed version will have an open first bound and so the induction
variable must be incremented first.
Also unified the way of extracting HeaderInfo out of changed calls
(e.g., `indices.reversed()`), and fixed declaration parents in
ForLoopsLowering.
The <Type>Array.iterator used to lack next<Type>() method (KT-16626).
The -Xtypedarray compiler key enables translation of primitive arrays
to TypedArrays, and primitive array`is`-checks (KT-15358, KT-14007,
KT-14614, KT-16056).
This patch mutes the following test categories:
* Tests with java dependencies (System class,
java stdlib, jvm-oriented annotations etc).
* Coroutines tests.
* Reflection tests.
* Tests with an inheritance from the standard
collections.
See the issue and the test. The problem was that when generating
call to `foo` method in member scope of `AT<*>` its resulting descriptor
after substitution and approximation was: fun foo(x: Nothing..Array<out Nothing>).
This signature is correct, but when using this parameter type
for generating a vararg argument the assertion is violated that
the type of the argument must be an array
(by default we're using lower flexible bound everywhere)
The solution is using upper bound for flexible types that should
always have a form of Array<out T> for varargs (even for such corner cases)
both for Kotlin and Java declarations.
