Variants

Move

Fields

from: Allocation

to: Allocation

Move one allocation to another. Each allocation may be a register or a stack slot (spillslot). However, stack-to-stack moves will never be generated.

Move edits will be generated even if src and dst allocation are the same if the vreg changes; this allows proper metadata tracking even when moves are elided.
