Hi Laurent
This pagraph exactly is a cutpaste of the Motorola Programmer's
reference manual.
I didn't mean to add it as commits to the patch.I just want to introduce this
instruction to the reviewer.
So don't worry about the copyrights.

This patch aims to add CMP2 instruction for m68k family.
Description: Compares the value in Rn to each bound. The effective address
contains the
bounds pair: upper bound following the lower bound. For signed comparisons, the
arithmetically smaller value should be used as the lower bound. For

Mainline target-m68k supports coldfire only.
There is an external tree for full m68k support:

That said, before you send this to them...

Hi,
did you test it ?
because after just a first glance this patch seems wrong as the tmp variables
cannot be used beyond the first tcg_gen_cond() (conditional branches clobber
temporary vars), you must use tcg_temp_local_new() and tcg_temp_free().
