Subject: Re: [Qemu-devel] [PATCH] PPC: Introduce 32bit only cmp ops

In-Reply-To: <20130508102910.GQ5000@ohm.aurel32.net> (Aurelien Jarno's message of "Wed\, 8 May 2013 12\:29\:10 +0200")

Aurelien Jarno <aurelien@aurel32.net> writes:

  You have to declare the L bit as invalid, so that trying to execute a
  64-bit cmp* instruction on a 32-bit CPU causes an invalid instruction
  exception.
  
Don't people read what I write?

I give up.

Goodbye.
