I once used to use 3.4-2 source tree to make a VM for the SL-series
Zaurus PDAs that use Linux/XScale platform.

In my environment, I turned off (undef'ed) DOUBLE_WORD_ORDER.

Invalid opcode doesn't sound good...

Rather, you might want to define those REGs as null strings.
# define IP_REG
# define SP_REG
# define CB_REG

You might want to take a look at the "memo" file in
It "briefly" describes what I did to make it work.
