[Qemu-devel] [Bug 1623020] [NEW] emulate amd64 binary on arm7 host

Public bug reported:

I'm trying to run a Go program compiled for amd64 on a Raspberry Pi.
Here is an example :

===
// main.go
package main

func main() {
        println("hello world")
}
===

Then here is the output I'm getting :

===
> GOARCH=amd64 go build main.go
> ../qemu/build/x86_64-linux-user/qemu-x86_64 -strace ./main

I'm running the latest qemu (commit
7263da78045dc91cc207f350911efe4259e99b3c), which was compiled with
"../configure --target-list=x86_64-linux-user --static".

The go version is 1.7.1, and the system "Linux raspberrypi 4.4.11-v7+
#888 SMP Mon May 23 20:10:33 BST 2016 armv7l GNU/Linux".
