Hello everyone,

I am an Outreachy intern at LLVM and I will be working on implementing
GlobaliSel for M68k backend. I have wired up globalisel for M68k up to
the point where we can select return void. But M68k is big endian and
globalisel doesn't support big endian.

I have created a test case to test  my implementation:

; RUN: llc -mtriple=m68k -global-isel -stop-after=irtranslator < %s |
FileCheck %s

; CHECK: name: f
define void @f() {
  ret void

But I get an error:

LLVM ERROR: unable to translate in big endian mode (in function: f)

How do I convert this error into a warning?
