Does anyone know where I can see the source for the primitive types such as Int? I’m interested in seeing how mapping to int, and boxing to java.lang.Integer is implemented.
So far I found a Generator class: https://github.com/JetBrains/kotlin/blob/master/generators/builtins/primitives.kt
And this native generated file, but I can’t see an equivalent for JVM or where the conversion is handled.

Primitive types are basically all over the compiler code, so it’s difficult to select a specific point. The closest I can think of is this method in the JVM backend which does all the boxing/unboxing: https://github.com/JetBrains/kotlin/blob/9097d0918c8c01c162ca4483599fdf13a0352cc1/compiler/backend/src/org/jetbrains/kotlin/codegen/StackValue.java#L630

I see, thanks!
