panic: unknown struct {}{}:{}

[stalecu]

Hello! I am new to TinyGo, so I decided to try it on my trusty RP2040. I cloned the repo on the release branch (which I suppose means I am on 0.28.1) to a separate repository, built LLVM myself (it didn't want to comply with my system LLVM-15 on openSUSE Tumbleweed, but oh well) and then symlinked tinygo to /usr/bin. Then I created a new project (module?) and this is the contents of hello.mod:

package main

import (
    "machine"
    "time"
)

func main() {
    led := machine.LED
    config := machine.PinConfig{
        Mode: machine.PinOutput,
    }

    led.Configure(config)
    for {
        led.Low()
        time.Sleep(time.Millisecond * 500)

        led.High()
        time.Sleep(time.Millisecond * 500)
    }
}

and this is what I get when building with tinygo build -o blink -target="pico" ./hello.go (to simplify the output a bit, I replaced my actual tinygo path with $TINYGO_PATH:

panic: unknown constant: struct{}{}:struct{}

Is there something I'm missing? And perhaps a way to reinstall everything from the tarball if that might be the culprit. Thank you for your attention.

Edit: I nuked everything and tried installing it from the tarball... maybe LLVM was acting weird? I don't know.

panic: unknown constant: struct{}{}:struct{}

It seems like you may have compiled against golang.org/x/tools >= 0.9.0. This version started lifting struct and array constants since golang/tools@71ea8f1 and the compiler doesn't handle that in createConst yet.

This would be fixed by #3883.
