Implementation is very similar to the `enumValues` intrinsic.
Java enums and old (pre-1.9) Kotlin enums will be supported in a
subsequent commit.
#KT-59710
Function `apiVersionIsAtLeast` was introduced to be able to have
different inline function content inlined to user code call sites
depending on their api version settings. Thus, it should not be
compile-time evaluated when being called in the body of inline stdlib
function.
^KT-59452: Fixed
Disabling of this language feature (see KT-57570) was not supported in
the (default) light tree mode, and after this change it will not be
supported in the PSI mode as well. This makes the behavior more
consistent and allows us to remove the directive
IGNORE_BACKEND_K2_LIGHT_TREE in the future (KT-56757).
If `-Xno-unified-null-checks` is specified, do not throw exceptions, but
rather revert to the old behavior, with source code in exception
messages.
Note that `-Xno-unified-null-checks` is a flag which enables behavior of
Kotlin 1.3. It can be removed once we no longer support API version 1.3.
Since we put object's hash code in toString, we end up in putting
non-stable hash code to constant table, which leads to unstable
binaries.
#KTI-1193 Fixed
This is a low-level extension point for Kotlin/JVM, which is supposed to
be used instead of ClassBuilderInterceptorExtension.
#KT-54758 Fixed
#KT-56814 Fixed
during tail-call optimization.
There can be code, where all next instructions are non-meaningful and
there is a back-edge, for example, while(true){}. Previously, analyzer
incorrectly assumed, that this cannot happen. Now, it keeps track of
visited instructions and says, that there is no meaningful instruction
in such case.
#KT-56815 Fixed
FunctionalTypeKind can be used in FE 1.0 too, so there is no need to
keep both classes. Also, removal of FunctionClassKind simplifies work
with FunctionalTypeKind in common code, like Analysis Api
Before, the only way of getting analyzable elements was to create an
analyzable file by using 'createAnalyzableFile()'. So made all utilities
available in 'KtPsiFactory' useless as they delegate to 'createFile()'
that always set the 'doNotAnalyze' flag.
The new behavior is to pass the 'analysisContext' instead if it is
passed to the 'KtPsiFactory' constructor.
The newly appeared API is going to be used in the Kotlin's UAST
implementation.
Merging array types with different element types, for example
`[Lj/l/String;` and `[Lj/l/Object;`, now produces `[Lj/l/Object;`
(instead of `Lj/l/Object;`), which allows for more precise tracking of
null values because we assume that AALOAD on a non-array typed value is
possible only if that value is null.
#KT-54802 Fixed
These should only have ever been necessary for field type inference in
coroutines, which should have been fixed by 0fc676a20c.
Unlike 903a5d69a4, this time the change is in an optimization pass.
Advantage: optimization passes have a closer to the JVM view of the
bytecode, which makes this change significantly more likely to be correct.
Disadvantage: technically we don't really guarantee optimization passes
other than FixStack will run at all. For KT-54581 this is 100% fine
since the problem itself is caused by redundant checkcast elimination in
the first place (otherwise there would've been a redundant cast to
String), but for KT-53146 this means the fix is somewhat incidental and
not necessarily guaranteed.
