State-Transition-Aware Spilling Heuristic for MLC STT-RAM-Based Registers

Algorithm 2

SSCM-based register allocation algorithm.
while not empty do
if there is an with degree   then
obtain the frequency set by offline profiling
sort variables based on the descending write cost
choose with MAX COST
add to spilling_list
end if
ifno variable has been spilled then
color the variables in reverse order of deleting
spill each everywhere
rebuild the interference graph and repeat the procedure
end if
end while
