register allocation
<compiler, algorithm> The phase of a compiler that determines which
values will be placed in registers. Register allocation may be combined with
register assignment.
This problem can be shown to be isomorphic to graph colouring by relating values
to nodes in the graph and registers to colours. Values (nodes) which must be
valid simultaneously are linked by edges and cannot be stored in the same
register (coloured the same).
See also register dancing and register spilling.
