--- Comment #1 from Alan Modra <amodra at gmail dot com> ---
Regarding ppc-opc.c, TITAN on those lines *disables* that entry for titan.  So
the mtibatu/l are enabled for ppc in general except titan.  The mtivor32..34
are enabled for PPC_OPCODE_SPE and mtivor35 for PPC_OPCODE_PMR.  Only the
latter flag is enabled for e6500.

The Freescale reference manual for e6500 that I have mentions IVOR32 and
IVOR33, so it would appear that modifying the PPCSPE on those lines (and
mfivor32,33) to be PPCSPE|E6500 will fix this for e6500.  I'll commit a patch
to do that.

Also, it seems rather a lot of spr related mnemonics should be disabled for
e6500.  Please send a patch to address@hidden, if you care enough to
fix them.
