Is there anything similar to AbstractFirBlackBoxCodegenTestBase for native targets?
I would like to create some tests for native codegen logic, but it seems all blackbox codegen tests are JVM based.

[Rick Clephas]

It looks like AbstractNativeCodegenBoxTest is used for native, but that isn’t part of the test infrastructure 😅

Native tests indeed use different test infrastructure, which is not published
And even if it was, I'm not sure that those tests will work outside of Kotlin repo, unfortunately

You can create a request in YouTrack for this

but it seems all blackbox codegen tests are JVM based

JS and WASM test use the same infrastructure as JVM, but the implementation is located in the js.tests, which is also not published

Thanks. Would there be any obvious problems/downsides to using JVM based tests for native codegen logic?
I mean both use FIR and IR, not sure how much the target will affect the accuracy of the tests.

[dmitriy.novozhilov]

I see the following obstacles on this way:
• proper setup of native backend in the facade after fir2ir is over
• implementation of llvm facade for different platforms (as native backend produces llvm bitcode, not native code directly)

[dmitriy.novozhilov]

Also I have no idea how to properly implement box runner for native binaries

[Rick Clephas]

Alright thanks. I’ll have a look at AbstractFirBlackBoxCodegenTestBase and see how far I can get with that 🤞🏻.
Most of the codegen logic should be platform agnostic anyways.

[dmitriy.novozhilov]

The logic itself -- yes. But the entrypoint is different
I even don't know in what exact place the native backend entrypoint is located

[Rick Clephas]

I see. I was thinking of just ignoring the whole native target. “pretending” that the compiler plugin normally runs for JVM instead of native.
Not really the same, but I am basically only interested in the FIR and IR dump.

[Rick Clephas]

I also have some integrations tests in a sample project. So that should test the complete setup for native targets.
I am mostly looking for an easy way to test and debug the FIR and IR logic of the plugin
