$t1- Any general-purpose register,
$0to$31, using its numeric or named spelling, such as$8or$t0($zerois$0;$rais$31). $t2- A general-purpose register. It may be the same register as
$t1. $t3- A general-purpose register. It may be the same register as
$t1.
Like 'rotr' but the rotate amount comes from the lowest 5 bits of register $t3 rather than an immediate constant.
# Initialize both inputs, then execute rotrv with initialized inputs. Inspect $t2: 3758096384.
