In tests merged from boxAgainstJava in 29b96aa1, some directories were
named slightly differently compared to box, e.g. "property" vs
"properties", "varargs" vs "vararg". This change renames these, moves
some of the tests to more fitting directories, and also renames
"visibility" to "javaVisibility" because it's about Java visibilities
specifically.
FirVisibilityChecker::isVisible checked if a private declaration can be
accessed at a use site by matching class ids of the private
declaration's owner with the use site's containing class
declarations. When the private declaration is defined in an enum
entry and used in the same entry, its owner class id has the enum
entry name, but the use site is in an FirAnonymousObject, which has
"anonymous" as the class id. This causes visibility check to fail.
This PR fixes owner class ids of declarations defined in enum entries
to be the same as normal anonymous objects.
In order to hide synthetic property isEmpty from JDK 15, there was
added additional logic in 5cc12b49fc but
it also lead to the fact that now it's impossible to call synthetic
property `declaringClass` on `Enum` as it's in the same list as method
isEmpty(). Note that it's questionable behavior, probably we should
also hide `declaringClass` as well but for now we turn it back to
preserve compatibility
#KT-42467 Fixed
This commit handles "subclass: super-interface by delegate-expression".
During Psi2Fir, for each delegate, we add to the subclass a synthetic
field (which has type super-interface), and an assignment of the
delegate-expression to the synthetic field in the primary constructor,
so that the delegate-expression can be resolved and transformed along
the way.
During Fir2Ir, we look up delegatable members from the super-interface
and generate corresponding functions/properties for the subclass.
TODO: support for generic delegatable members and generic
super-interface.
Without this commit, JVM name mapping logic in BE does not work for FIR,
because FIR cannot use old BuiltInsPackageFragmentImpl descriptor.
In this commit we add our own implementation thus fixing
a pack of FIR black box tests.
Now FE IR -> BE IR transformation is performed in multiple stages
controller by Fir2IrConverter. Stages are
* files & classes registration
* supertypes & type parameters handling
* functions & properties signature generation
* body generation
After each step we have guarantee (with exception of local classes &
type inference combination, and external symbols) that required symbols
(class/function/property/variable/type parameter)
are already bound to real declarations and have correct parents.
This commit also fixes incorrect parents for local classes
Usually FIR enum entry is initialized by anonymous object,
which is the container for all enum entry' declarations.
However, for simple enum entries there is no need of initializer at all.
Normally, the fact that is was Unit was not visible as enum constructors
are lowered to normal class constructors anyway. The exception is when
the arguments are reordered, causing the incorrect return type to leak
into the block that holds temporary variables.
When replacing an enum entry reference with `this`, you need to take
`this` from the function's `dispatchReceiverParameter`, not the class's
`thisReceiver`. Otherwise the code generator fails to find the reference
among accessible variables.
The synthesized arguments caused the size of default value mask off by
one when it is close to the boundary of Int.SIZE, which in turn
resulted in wrong signature at call sites.
The reference can be lowered to `this` if it is captured in the lexical
scope of the corresponding enum entry, and not used by the enum entry's
super constructor. Otherwise, it is lowered to
`GETFIELD SomeEnum.SomeEntry`.
