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

[Bilal Amarni]

I see, I'll close the ticket then.

Do you have any recommandation on how I could achieve this? It is
actually a 64-bit CPU (armv8 from Raspberry Pi 3) but it's running on a
32-bit OS / kernel.

Title:
  emulate amd64 binary on arm7 host

Status in QEMU:
  Invalid

Bug description:
  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 :

  ===

  I'm running the latest qemu (commit
