Previously, the checker executed for every declaration i.e. every
declaration was considered as expect declaration. Because of that in
some cases this checker could eat 6% of compilation time.
After this commit only declarations marked with expect or actual
are checked. To achieve that, logic, that do reporting about missing
actual modifier was moved to the Actual part.
Please note, that in cases where there is no expect/actual modifier at
all other errors (like redeclaration and missing body on "actual"
declaration) would be reported.
Useful nodes:
- In this checker reportOn is always the same as
descriptor.sourceElement.ktElement. This is because the only case when
it isn't true is PropertyAccessors and they are filtered
- Annotation constructor descriptor isActual == true all the time
- previously for weak incompatible members ACTUAL_MISSING
was not reported
- the logic here is super complicated and crazy, but I don't think that
there is sense to refactor it in the old FE
This directive anyway does not make test run twice with OI, and with NI
It only once run the test with specific settings (// LANGUAGE)
and ignores irrelevant (OI or NI tags)
Specifically, the report the following 4 errors.
* NON_VARARG_SPREAD
* ARGUMENT_PASSED_TWICE
* TOO_MANY_ARGUMENTS
* NO_VALUE_FOR_PARAMETER
Also added/updated the following position strategies.
* NAME_OF_NAMED_ARGUMENT
* VALUE_ARGUMENTS
Combined this and the checker of
SUPERTYPE_INITIALIZED_WITHOUT_PRIMARY_CONSTRUCTOR together.
Also fixed SUPERTYPE_INITIALIZED_WITHOUT_PRIMARY_CONSTRUCTOR incorrectly
repoted as warning instead of error.
The check has already been partially implemented in
org.jetbrains.kotlin.fir.resolve.calls.FirCallArgumentsProcessor. This
change completes the missing piece that determines if a `FirFunction`
has stable parameter names.
Update includes:
- Changing syntax of `OI/`NI` tags from `<!NI;TAG!>` to `<!TAG{NI}!>`
- Fix some incorrect directives
- Change order of diagnostics in some places
- Remove ignored diagnostics from FIR test data (previously `DIAGNOSTICS` didn't work)
- Update FIR dumps in some places and add `FIR_IDENTICAL` if needed
- Replace all JAVAC_SKIP with SKIP_JAVAC directive
In particular, this commit includes:
* Attempt to abstract access to FirSourceElement via FirModifier
* Add more visit functions to DeclarationCheckersDiagnosticComponent
* Add messages+factories for 4 modifier-related errors and warnings
* Introduce FirModifierChecker
