--- Comment #3 from Mike Frysinger <vapier at gentoo dot org> ---
the setting of 0xDEADC0DE & 0xBAD0BAD0 looks kind of bogus.  based on other
functions in here, like do_dmtc1b, i wonder if it shouldn't be:

-- a/sim/mips/mips.igen
+++ b/sim/mips/mips.igen

   TRACE_ALU_RESULT (GPR[rt]);

and should we do this for 010001,00001,5.RT,5.FS,00000000000:COP1:64,f::DMF=
