Re: [Liquidfire-devel] rol/ror

[Marcelo S. <mar...@bs...>]

rol/ror have just 3 bits in the counter field, then the valid
range for imediate data is #1 up to #8, for other values, you must
use a counter in a register:

	moveq 	#0xf,%d2
	rol 	%d2,%d3

or two rol instructions:

	rol	#8,%d3
	rol	#7,%d3

best regards,
