kotlinlang

Hello, can someone tell me how Kotlin inline functions that are not in the same module? Does it rely only on the bytecode? And in what compiler step does it happen? I am trying to read the source code but I am having trouble to find it. I saw that functions of other modules are represented by Fir2IrLazySimpleFunction, but I can't find where the inline happens.

Yes, it uses bytecode. <https://github.com/JetBrains/kotlin/blob/cad2d1ac6bebfeaa7c9ea5e9254ca06def8b58a7/compiler/ir/backend.jvm/codegen/src/org/jetbrains/kotlin/backend/jvm/codegen/IrInlineCodegen.kt#L37|IrInlineCodegen> (and its superclass) is the entrypoint to bytecode inliner.
