This is a question for Laurent I think...
Where can I find the instruction times for the 'div' and 'mul' 64bit (long form) instructions in the Hatari timing table "falcon_cycle030.h"? e.g.
"divs.l <ea>,Dr:Dq"
"mulu.l" <ea>,Dr:Dq"
I see indirection to certain tables "table_falcon_cycles_DIVS_L" but the addressing mode for Dr:Dq does not seem to be present in the comments. Is it handled specially somewhere else?
Thanks,
Doug.
