invalid type error

[Arpit Aggarwal]

Hi all,

I am getting the following error when I try to generate assembly through the llvm IR (generated through llgo)
(command i used : llc channels.ll -o channels.o )


llc: channels.ll:17:44: error: invalid type for global variable
@__go_type_hash_identity = external global i64 (i8*, i64)

Channels.go

package main

// import "fmt"
// import "time"

func worker(done chan bool) {
    // fmt.Print("working...")
    // time.Sleep(time.Second)
    // fmt.Println("done")

    // send true to done
    done <- true
}

func main() {

    done := make(chan bool, 1)
    go worker(done)

    //wait for worker to send done
    <-done
}

I have also attached the go program and its IR.

What is the reason for this error and how it can be resolved?
Thanks in advance!

Regards
Arpit

Hi Arpit,

This was a bug in llgo's IR generator, which is now fixed as of r304689.

Thanks,

Peter

Thanks Peter!
One thing I want to ask is, whether the latest version compiles, because I had issues installing it few days back, so using an older version.
What is the best way to install llgo(is it using the llgo-README)? Should I compile the latest llgo with older llvm I am working or update all?
