I seem to hit a weird emulation issue. I'm still new so take what I say
with a grain of salt.
In my tests the LFDU instruction is not updating the Condition Register
($CR) when the condition becomes ZERO.
The following assembly will loop forever.
falconScrubFloop:
lfdu 0,8(r17) /*
load floating point value and increment register ( f0 <- ($r17) and
$r17 += 8 */
bc 16,0,falconScrubFloop
/* branch till counter == 0, This is equivalent
to bdnz or branch if not zero */
The MSR is set to allow floating point $MSR = 0x2000.
Not sure what's going on yet.
