Pavel Kirpichenkov ef44077cb7 [FIR] Restore variable fixation direction in call completion
Several tests are affected by the usage of fixation direction calculator in FIR.
Restored to mimimize test data changes.

It is unnecessary in FE10 because a type variable with unknown type
is inferred into an error type, but affects test data in FIR where
Nothing/Any is selected by direction (as a temporary measure).

CR candidate in spec test is Unresolved in FIR because top-level CRs are resolved as call arguments.
Resolution ambiguity is also present in FE10 when CR is wrapped into an id call.

FIR Analysis tests

Mostly, format of FIR analysis test is the same as the one described at compiler/testData/diagnostics/ReadMe.md.

DEBUG_INFO_EXPRESSION_TYPE and DEBUG_INFO_CALL are also partially supported but need to be written out explicitly in a test data file:

fun foo(
    x1: String,
    x2: Collection<CharSequence>,
    x3: MutableMap<out CharSequence, in MutableList<*>>
) {
    <!DEBUG_INFO_EXPRESSION_TYPE("kotlin.String")!>x1<!>
    <!DEBUG_INFO_EXPRESSION_TYPE("kotlin.collections.Collection<kotlin.CharSequence>")!>x2<!>
    <!DEBUG_INFO_EXPRESSION_TYPE("kotlin.collections.MutableMap<out kotlin.CharSequence, in kotlin.collections.MutableList<*>>")!>x3<!>
}

interface B {
    operator fun invoke(x: Int): String
}

class A {
    fun foo(x: Int) {
        fun baz(x: Double) {}
        <!DEBUG_INFO_CALL("fqName: A.foo.baz; typeCall: function")!>baz(1.0)<!>
    }

    val bar: B = TODO()
}

fun A.foo(x: String) {}

fun main() {
    fun A.foo(x: Double) {}
    val a = A()
    a.<!DEBUG_INFO_CALL("fqName: A.foo; typeCall: function")!>foo(1)<!>
    a.<!DEBUG_INFO_CALL("fqName: foo; typeCall: extension function")!>foo("")<!>
    a.<!DEBUG_INFO_CALL("fqName: main.foo; typeCall: extension function")!>foo(1.0)<!>
    a.<!DEBUG_INFO_CALL("fqName: B.invoke; typeCall: variable&invoke")!>bar(1)<!>
}

Specific Directives

  • // FIR_IDENTICAL should be prepended in a .kt file of an old diagnostic test when analysis result of old FE and FIR are the same
  • // FIR_IGNORE should be prepended in a .fir.kt file of an old diagnostic test known to fail with exception
  • // !DUMP_CFG generates .dot file with rendered data flow graph (see comment at org.jetbrains.kotlin.fir.AbstractFirDiagnosticsTest)
