Question

Difference between variant 1 and variant 2 intermediate code

Answer 1

The two intermediate code variants differ based on the information that is provided in their operand fields.

In Variant 1 intermediate code, the first operand is a single digit number that usually represents a register code. In some cases, the register code is replaced by a condition code. The second operand is always a memory operand.

In Variant 2 intermediate code, their processed forms may at times take the place of the operand fields of the source statements.
