Detailed Description

Helper class that determines VL can use the same opcode.

Alternate instruction is supported. In addition, it supports interchangeable instruction. An interchangeable instruction is an instruction that can be converted to another instruction with same semantics. For example, x << 1 is equal to x * 2. x * 1 is equal to x | 0.
