The instructions from the original (dyngen) patch were tested using a
modified version of:
* test-powerpc.cpp - PowerPC regression testing
*
* Kheperix (C) 2003-2005 Gwenole Beauchesne
that didn't require poking around in the guts of QEMU. I turned it into
a standalone application that could be run in Linux. I then ran it on a
74xx machine and under usermode emulation with QEMU and compared the
results.
I assumed that porting it over would show no difference in
functionality, but I see from running it this morning that m{f,t}vscr,
vmul{e,o}*, and vs{l,r} are broken. Everything else works OK. I will
poke at the failing instructions and submit updated patches for them.
