Operands
$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.
Treats both operands as unsigned 32-bit integers (0 to 4294967295). Use this when comparing memory addresses or unsigned counters.
# Compare signed and unsigned bit patterns: $t0 is -1 (0xFFFFFFFF), $t1 is 1. Inspect $t2: 0.
