Shmuel,
I know that it's model dependent and also depends on the cache loading, but are there cases where there is a measurable performance difference between these?LAY Rx,4096 LHI Rx,4096
well, with LAY the second operand is an address with a base and an index register but LHI it is an immediate value. Guess: LAY is slower- but I doubt, that it is measurable or has been measured. And even if it is measured/measurable- does it matter with executing three or more instructions at the same time?
