In addition to fixing getContainingDeclaration, change origin of
multifile facades to FILE_CLASS since the corresponding class descriptor
should also be skipped when computing containing declaration. This fixes
the problem with internal function calls in -Xmultifile-parts-inherit
mode (previously we incorrectly mangled the function name in
MethodSignatureMapper), and also fixes coroutine intrinsic calls when
compiling kotlin-stdlib with JVM IR. In the latter case, all intrinsics
(such as isBuiltInSuspendCoroutineUninterceptedOrReturn) are present in
sources, and were previously not detected as intrinsics by the code in
`generateInlineIntrinsic` because the FQ name didn't match: it had an
additional component for the file class name.
Technically a backwards compatibility problem, as the new backend
*consistently* renamed `f$default` on `f` with `@JvmName("g")` to
`g` instead of `g$default`, so it all worked out. However, this
breaks when encountering libraries compiled with the non-IR backend.
Otherwise a local class in a field initializer or anonymous init block
is copied into each constructor of the containing class (because
InitializersLowering calls deepCopy).
Since the code structure no longer resembles the original source code
here, record a custom EnclosingMethod mapping before moving such
classes, and use it in codegen.
Create a separate _ir.txt bytecode listing file for JVM IR, to avoid
duplicate tests and to fix "Codegent tests on different JDKs"
configuration where this test is muted but passes because only execution
is checked there, not bytecode listing.
This directory is skipped in JVM IR test generator, so they won't show
up as failed anymore.
Note that only failing tests are moved to oldLanguageVersions/. Tests
which already pass are still being run. It may be useful not to break
them in case we _do_ need to support some pre-1.3 language feature
switches in JVM IR.
- Added tests to demonstrate broken behaviour: the interaction of inline
functions and callable references with varargs and defaults in various
combinations.
- Refactored InlineCallableReferencesToLambdaPhase to look like and use
some of the infrastructure from CallableReferenceLowering.
- Lifted some of this infrastructure out to be broadly reusable.
Take branching and method calls into account when finding the line
number of the continuation. If there is no line number before
branching instructions or method calls, the following code is
still on the line of the suspend call itself.
This fixes a couple of issues with incorrect line numbers for
multiple throws on the same line or multipe suspend calls on
the same line.
In addition, it avoids the need to spam the method node with
repeated line number instructions in the IR backend.
When creating delegation redirectors for default implementations of
interface functions, `overriddenSymbols` should be repaired across the
whole module, not just a particular file.
With the mangling added in 488418d960, there's no longer any risk in
writing "special" function name ("<anonymous>" in this case) to the
local variable table.
#KT-34356 Fixed
- Extract all backend codegen tests that specifically target behaviour
in to-be-deprecated functionality from language versions < 1.3"
- Remove those tests from the JVM IR test suite.
If "null" was the first entry in an optimizable "when" over enum,
mapRuntimeEnumEntry was called before mapConstEnumEntry, and the
$WhenMappings field was not created. Now both mapConstEnumEntry and
mapRuntimeEnumEntry create this field on the first access
suspend functions and lambdas.
Otherwise, when state-machine builder splits instructions and adds
LINENUMBER between states, the information becomes corrupted.
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.
Rely on the frontend weeding out cases that are not supported.
In psi2ir, introduce all the parameters before processing default
values.
Change the DefaultArgumentStubGenerator to generate code that
matches the behavior of the current backend.
