One aspect of the differences between the two is that LAY has a larger
footprint
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
regis
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
