Abstract

An instruction is designated to remain as an invalid instruction.

Motivation

The invalid instruction can be used as a distinct reason to abort execution.

Specification

The opcode 0xfe is the INVALID instruction. It can be used to abort the execution (i.e. duplicates as an ABORT instruction).

Backwards Compatibility

This instruction was never used and therefore has no effect on past contracts.
