mulo
Multiplication with overflow
Multiplies $t2 by $t3, or an immediate, as signed values and puts the low 32 bits of the product in $t1.

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. imm- An immediate value: a signed 16-bit value (
-32768to32767) or a 32-bit value (-2147483648to4294967295). The assembler chooses a supported encoding for the value and other operands; a pseudoinstruction may expand into several instructions.
# Initialize both inputs, then execute mulo with initialized inputs. Inspect $t2: 21.
