68000 instruction test suite QL

[XorA]

Less than 1.5 hours (I missed the end time as I was washing up)

I guess it should be quite a bit less, I re-tested QPC yesterday and it only took 30 minutes... much faster than I remembered (mostly used it on MiSTer a few years ago which took quite a bit longer...). I checked the screenshot timestamps to get the duration

I did not think of that, 11:48->13:05

It seems I could use your testsuite, as the following code from uqlx I guess means its nbcd instruction does not work.

Code: Select all

IDECL(nbcd)
{ 
  w8      d,r;
  w8      d2,r2;
  d=ModifyAtEA_b((code>>3)&7,code&7);
  d2=((d&0x0f)>9? 9:(d&0x0f));
  d>>=8;
  if(d>9) d2+=90; else d2+=d*10;
  carry=d2!=0;
  r2=100-d2;
  if(xflag) r2--;
  xflag=carry;
  zero=zero && r2==0;
  r=(r2%10)+((r2/10)<<4);
  RewriteEA_b(r);
NEXT;
}

Note the shifting d all 8 bits, then checking for a value > 0

Interesting. Probably need to fix the same in Q-emuLator, then.

Looks like I had already fixed NBCD in Q-emuLator for the general case, but there was still an issue when the input value was $FA.

Ace, look forward to the new release. (I had not got round to running full testsuite on Q-Emulator).
