If I wish to create a kotlinc-pascal, what is the recommended stable version to start working?

[ventura]

Both compileTest task fail for v1.9.20 due a JDK6 dependency (both Intel i7 and Apple M1)

[dmitriy.novozhilov]

If you want to fork the compiler your can use any version you want, but I recommend master

[dmitriy.novozhilov]

As for jdk 6 please read readme
https://github.com/JetBrains/kotlin#build-environment-requirements

[ventura]

Something that is not clear to me is when the code becomes IR

[ventura]

suppose I have module implemented in pascal, but I am importing it into pascal_tutorial.kt

[ventura]

@dmitriy.novozhilov The FHIR layer is responsible for automatically transpile the IR into kotlin methods?

[Piotr Krzemiński]

@ventura sorry, I don't know what FHIR is, when working on kotlin-python I just remember modifying implementation of methods for the JS target that translate IR into a given target format

@Piotr Krzemiński https://youtrack.jetbrains.com/issue/KT-47273

[ventura]

sorry, the original message was for @dmitriy.novozhilov

[dmitriy.novozhilov]

I also don't know what is FHIR is
There is no such thing in the compiler

A long long time ago, when I was working on Intel with compilers, the idea was precompile everything to LLVM intermediate language

[ventura]

This way it would be simpler test new types optimizations that were impossible on GCC

[dmitriy.novozhilov]

K/Native works in the same way

[ventura]

As far as I got, the transform KONAN into JS and JVM, correct @dmitriy.novozhilov

[dmitriy.novozhilov]

konan is just a name for K/Native compiler
The main pipeline for all platforms looks in the following way:
Parse tree ->fir -> ir ->bytecode/js code/llvm

[ventura]

@Piotr Krzemiński 20 years ago it was hell trying to add parallel optimizations in compile time in GCC 3.x.x

[dmitriy.novozhilov]

The picture above is quite inaccurate

[ventura]

@dmitriy.novozhilov so, tecnically speaking, I can do:

parse tree -> fir ->
• bytecode/lua
• bytecode/jvm
• bytecode/cil
• bytecode/python

[dmitriy.novozhilov]

You missed ir part
All backend s lower ir to smth more similar to platform representation and then convert lowered ir into platform representation

[dmitriy.novozhilov]

[ventura]

@dmitriy.novozhilov so each code IR code generation requires its own taylored plugin, correct?

[ventura]

If FIR was documented, it would be marvelous

[dmitriy.novozhilov]

so each code IR code generation requires its own taylored plugin, correct?

Kinda. This is called separate backend

[dmitriy.novozhilov]

And you can not ping me every message, I'm already in this thread

Make it works in K/N is 1000x times harder than adding it to github.com/roselyn
