There is a `gradle-api-impldep.jar` created by Gradle which contains
our nullability annotations, but relocated in the
`org.gradle.internal.impldep` package
In the deserialization process we use a `HAS_ANNOTATIONS` flag, and
if it is present on the declaration, we do not try to build annotations
for it, even when they are actually present and even when they are
relocated
(see usages of Flags.HAS_ANNOTATIONS in org.jetbrains.kotlin.serialization.deserialization.MemberDeserializer)
In the stubs builder we also use this HAS_ANNOTATIONS flag, but we did
not use it for the value parameters. This commit fixes that - now, if
the `org.jetbrains.annotations` packages are relocated, it should not
cause `Stub Mismatch Error` for the value parameters
Lets consider two possible cases:
1. If the value parameter has a user-defined annotation,
it will be marked as having annotations (HAS_ANNOTATIONS == true), and
both stubs and deserialized descriptors will have to
use all available annotations (even a relocated ones)
2. If, for example, the value parameter is of non-nullable type, it will
have a `@NotNull` annotation on it, but will be marked as having
no annotations at all (HAS_ANNOTATIONS == false), since `NotNull` is
considered as auxiliary by the compiler. Because of the flag, both stubs
and descriptors will ignore all present annotations (even if they were
relocated)
In the both cases, the stubs and the descriptors will completely match

See IDEA-262971 about fixing the Gradle jar and the details
N.B. This does not fixes the cases when `kotlin.Metadata` and similar
annotations are relocated (e.g. KT-25709)
Compiler check for 'when' exhaustiveness requires that module
descriptors of a sealed class and its inheritors are the same (reference
identity matters). Prior to this commit and under some conditions they
were not. Details follow below.
Resolution related data structures (resolution facades) are organized
into trees (sdks, libs, and modules have their own nodes/facades,
module/class descriptors are stored inside). And the trees themselves
are put into a map associating so called PlatformAnalysisSettings and
GlobalFacades (plays a role of a root). PlatformAnalysisSettings is an
abstraction describing target platform and sdk of a module. The more
combinations exist for a project the more facades are used. Please, see
KotlinCacheService for more details.
So why a module can have multiple ModuleDescriptor-s?
Every tree mentioned above is an isolated resolution environment
containing its own instances of the outer world descriptors. Say, if a
project has modules X, Y, Z and we consider X then all three might have
their own vision of X, i.e. 3 descriptors exist at a time.
What descriptor instance does compiler get?
The path starts when the user opens a file in the editor and
highlighting pass starts (see usages of
ResolutionUtils#analyzeWithAllCompilerChecks). Module descriptor stored
in the resolution tree of the file's module gets injected into the
compiler's context. Starting from this moment compiler sees other
modules through the prism of a single resolution facade (tree).
Descriptors residing outside are alien.
This commit allows IdeSealedClassInheritorsProvider to figure out what
PlatformAnalysisSettings are associated with the resolution facade (read
ModuleDescriptor) seen by the compiler. Later on the same facade is used
to provide correct instances of sealed inheritors back to the compiler.
Module descriptor names in the form of 'stableName' depend on a build
system. See JvmCodegenUtil#getModuleName(). For JPS we get
<module-name.main> or <module-name.test> whereas for Gradle we get top
level <module-name>.
This commit changes approach: ModuleDescriptor-to-Module conversion is
no longer made by name. ModuleInfo is utilized instead.
^KT-45074 fixed
Extract a service interface out of ControlFlowInformationProviderImpl
and register its implementation in two "leaf" modules: 'cli',
'idea-core'.
This improves parallel build, since a lot of modules depend on
'frontend' but only these two modules reference the implementation and
thus depend on the full CFA implementation now.
Do not use default parameter value for functions with only 1 or 2 call
sites, since it doesn't add much value but provides a dangerous
possibility to forget to pass the real implementation.
Logic of module dependencies is enhanced to filter out incompatible
common -> platform dependencies. However the reversed index for getting
all modules that use libraries doesn't take this filtering into
account and returns all modules based exclusively on order entries.
This leads to incorrect library dependency calculation.

Using "JVM_1_8" always resulted in incorrect mapping of Kotlin
annotation targets to Java element types.
The change in AbstractKotlinRenderLogTest is needed because while
CliTraceHolder.module is technically a descriptor leak, it was never
detected by this test accidentally, because of the depth cutoff equal to
10, which started to not be enough after the minor refactoring of
replacing `Delegates.notNull` with `lateinit`.
findDecompiledDeclaration.kt: Use same DescriptorRenderer options as Decompiler
DescriptorRendererImpl.kt: not enforce different AnnotationArgumentsRenderingPolicy for function type annotations
This will fix KTIJ-563 where rendered Descriptors are used as Keys
for GOTO navigation into decompiled sources.
^KTIJ-563 fixed
Fix built-ins for JVM platform and make them consistent
with module's dependency on standard library. Changes
don't affect non-JVM platforms.
Previously all built-ins in IDE were loaded from classloader
and were based on the same pre-serialized .kotlin_builtins files.
This approach is generally not correct as built-in declarations
differ for different platforms, but it had been working for a while
without immediately observalble effects (see KT-33233 for more info).
After changes in standard library JvmBuiltins started producing
false errors (see KT-39728).
To fix this, JVM built-ins in IDE now utilize the same technique as
applied in CLI: using dependency on standard library as a module
for built-ins instead of artificial module that considers only
.kotlin_builtins.
Change summary:
- Provide JvmBuiltins with kind FROM_DEPENDENCIES
for all modules with stdlib dependency in IDE
- Add JvmBuiltinsPackageFragmentProvider to JVM-ish module resolvers
(JVM and Composite with JVM platform) to support their use as
built-ins module
- Create KotlinBuiltInsMetadataIndex file index for tracking libraries
containing .kotlin_builtins to support JvmBuiltinsPackageFragmentProvider
- Create KotlinStdlibIndex file index for tracking kotlin-stdlib(-common),
which looks for "Kotlin-Runtime-Component" manifest attribute
- Add caching service to track LibraryInfo for kotlin-stdlib(-common)
- Put LibraryInfo for kotlin-stdlib(-common) alongside SDKs
due to the need to resolve that modules in BuiltInsCache
- Update BuiltInsCache to separate JvmBuiltins by module's dependency
on stdlib and JDK
- Make platform of KotlinSDK common instead of JVM
- Set built-ins module lazily in IDE

As soon as JVM IR is enabled by default (in language version 1.5), use
the CLI argument `-Xuse-old-backend` or Gradle option `useOldBackend` to
switch to the old JVM backend.
Report a separate error when class files compiled with FIR are in
dependencies, in addition to the one for class files compiled with FE
1.0 + JVM IR.
