Incorrect cycle times? #96

Closed rjobling closed 2 years ago

rjobling commented 2 years ago

Love the new additions but some of the cycle counts seem wrong.

This should be 8 cycles not 18, I think: image

This also seems wrong, EASy68k reports 22cycles: image

I don't know these numbers well, so I'm going off what EASy68k tells me. I suppose it could be wrong in the second case.

Haha, nice find. Seems the lea opcode only has problems with a5 as source register ;)

For bchg, 68000 user's manual pg. 136 says for dynamic, memory 8 + EA (=10). So I would say, EASy68k is wrong, it seems to take from the column static, memory but that refers to something like bchg #3,(a4,d3.w).

My code just got faster :)
