An instruction is designated to remain as an invalid instruction.
The invalid instruction can be used as a distinct reason to abort execution.
The opcode 0xfe is the INVALID instruction. It can be used to abort the execution (i.e. duplicates as an ABORT instruction).
This instruction was never used and therefore has no effect on past contracts.
