EIP-5656: MCOPY - Memory copying instruction

Progress

Impact

  • HUB
    • misc/MXP
      • requires double compute of the new memory size (like CALL's)
      • requires also detecting zero size
    • misc/MMU
      • these operations would be carried out in 0 or two steps, like the IDENTITY precompile
      • first copy over data to fictious execution context
      • then transfer value back

Thus two distinct MMU operations of the form ramToRamSansPadding (or whatever.)
