I have written the following code in A and B modules. (both functions are declared at the top level in a file)

// A module
public fun Hi() {
    println("hi~")
}

// B module
public fun Bye() {
    println("bye~")
}

Module A has a dependency on module B, and I’ve enabled the Kotlin Compiler Plugin with

MyIrVisitor

.

internal class MyIrVisitor : IrElementVisitorVoid {
    override fun visitModuleFragment(declaration: IrModuleFragment) {
        declaration.files.forEach { file ->
            file.accept(this, null)
        }
    }

    override fun visitFile(declaration: IrFile) {
        declaration.declarations.forEach { item ->
            item.accept(this, null)
        }
    }

    override fun visitSimpleFunction(declaration: IrSimpleFunction) {
        logger.warn("[visit] ${declaration.name.asString()}")
        declaration.body?.accept(this, null)
    }

    override fun visitExternalPackageFragment(declaration: IrExternalPackageFragment) {
        declaration.declarations.forEach { item ->
            item.accept(this, null)
        }
    }
}

I expected both

[visit] Hi

and

[visit] Bye

to be printed, but only

[visit] Hi

was actually printed. Am I misunderstanding

visitExternalPackageFragment

?
