pretty minor difference, but failing one of our unit tests with new IR: we have a test that expects a failure containing the string

EasyMock.anyObject() must not be null

when using EasyMock to pass an expectation to a mock of a method expecting a non-nullable parameter. Using the new IR, the string is just

anyObject() must not be null

. Is this expected?

I updated my project to use Kotlin 1.4.30 and enabled

kotlinOptions.useIR

. I'm getting a bunch of errors when doing a clean build. Should I post those here as messages or create YouTracks issue for them?

Should I expect a *.klib to be generated for JVM after swithing to IR compiler? I've added the flag, but there seems to be no difference in terms of build outputs

We started to test the new backend and see a lot of red due to the Parcelize plugin? Is this a known issue? Happy to file a ticket if none exists (I wanted to double check first).

I’ve also just tried the IR backend on our code base (with 1.4.30) and ran into a different IndexOutOfBoundsException that doesn’t seem related to parcelize like the one above

IndexOutOfBoundsException: chars sequence.length:3389, start:1313, end:4337

While I couldn’t compile our entire project with the ir backend (due to the crash above ^), I was able to compile a decent chunk of it and profiled the build with the gradle profiler. The ir backend seemed to give a solid 10% overall build speed improvement compared to vanilla 1.4.30. I hadn’t seen any mention of build speed improvements for android/jvm from the ir backend yet, so this was a pleasant surprise.

if I compile a library with the IR backend, can non IR projects use that library?

Hello everyone! I have problem with new IR which expected to be fixed in kotlin 1.4.30 but I reproduced it and find out the reason of this exception https://youtrack.jetbrains.com/issue/KT-42021#focus=Comments-27-4720921.0-0 I don't know why, but in kotlin 1.4.20 I could pass not suspend function reference to function that accepts only suspend functions

Hi there. For testing the new IR compiler backend the documentation says to add the following block to the Gradle build file:

Copy code

compileKotlin {
    kotlinOptions.useIR = true
}

this gives a build error for Android projects. If I add the following under

android

in my

build.gradle

file it seems to work. Am I correct?

Copy code

kotlinOptions {
    useIR = true
}

Hello, just tried the new backend 1.4.31 on my project => build failed. Below the stack trace and attaching the source file on which it seems to have crashed. I do not have a simple way to reproduce available.

I am getting the below error very regularly when I build in IntelliJ with Kotlin 1.4.31 and Compose for desktop 0.4.0-build171. The only way I have found to fix it is to do a gradle clean and build. Is there a way I can get it to go away permanently? It seems to happen only when I edit my composable functions.

Hello, everyone! My app got an error and the app is an Android app, but I think this is the right channel for this topic. As long as I remember, the last thing I've done that might be contributing to this error is enabling the IR compiler on the Android Studio by the following line

Copy code

kotlinOptions.useIR = true

The view model has a LiveData that hold Kotlin's Result class

Copy code

fun doSomething(code: String, price: Long)  {
        repository.doX(code, price)
                .doOnComplete { _priceSubmission.postValue(Result.success(true)) }
                .doOnError { _priceSubmission.postValue(Result.failure(it.cause ?: it)) }
                .fromIo2Ui()
                .subscribe()
                .disposeOnCleared()
}

and the activity observing it by

Copy code

viewModel.priceSubmission.observe(this) { result ->
            if (result.isSuccess) {
                setResult(RESULT_OK)

            } else {
                val error = result.exceptionOrNull()
                if (error is HttpException && error.code() == 400) {
                    showDialog()

I was a little surprised to see that the

useIR

flag became a no-op with 1.5. Was this intentional? I’m aware that the new IR backend will be the default with 1.5. But I assumed setting it to false will go back to the old backend (rather than using another property). https://github.com/JetBrains/kotlin/blob/1.5.0-M1/compiler/cli/src/org/jetbrains/kotlin/cli/jvm/jvmArguments.kt#L195-L200

When trying out new IR, should we add

kotlinOptions.useIR = true

for every module we have? New IR works fine, no issues so far 👌

Not gonna lie, it’s quite discouraging if bugs reported for the IR backend over a month ago are targeted to be fixed in

1.5.20

rather than the

1.5.0

release https://youtrack.jetbrains.com/issue/KT-44891

Is JVM IR on by default in 1.5.0-M2?

With new backend IR, should kotlinx serialization library be updated to specific version? Getting this crash when run build with IR enabled (Kotlin 1.4.31, Kotlinx serialization 1.0.1)

Hello, just ran a quick benchmark on a Android Project, Kotlin 1.4.30, and it seems

useIR

does slow down the build a bit:

Copy code

useIR: false, clean & rebuild:
1. 41s
2. 41s
3. 40s

useIR: true, clean & rebuild:
1. 44s
2. 43s
3. 43s

Granted, it is only marginal slower since it is also only a relatively small project (single module) - but will it affect larger projects proportionally? Out of curiosity I also tried with

compose: true

and was rather disappointed:

Copy code

useIR: true, compose: true, clean & rebuild:
1. 53s
2. 52s
3. 52s

I honestly expected the new Backend to be if anything, then faster than the existing one?

I'm trying to test a fix in 1.5.0 m2 to see if this fixes an issue with IR compiler BUT I can't seem to run it because I use hilt in this project. I just added hilt last week. Hope I don't have to revert it. Searching in kotlinlang slack and on google hasn't gotten me any promising results. Am I missing something simple to just enable hilt working with 1.5+?

Not sure if it's a bug in the new backend or in MockK, but it sure is a difference in behavior: This test fails with the new backend and works with the old one.

We are having a failure on our CI, running UI tests, only after enabling the useIR option in our 🤖 project. The failure is about a custom rule failing with this

Copy code

protected val activity: T by lazy {
activityRule.activity
} must not be null

This is happening somehow else. also, if it helps,

Copy code

@JvmField
@Rule
var activityRule: SomeActivityTestRule<out T> =

I’ve been working on a compiler plugin that hooks in via

AnalysisHandlerExtension

, it just generates some extra files and nothing too complicated. It works fine on the old backend, but when IR is enabled it fails somewhere deep in the compiler for reasons that aren’t clear to me. Looking to see if I should file a bug or if there’s something I’m doing wrong using this API.
