Jakob Stoklund Olesen acaf9e9ce1 Be more aggressive about following hints. ... RAGreedy::tryAssign will now evict interference from the preferred register even when another register is free. To support this, add the EvictionCost struct that counts how many hints are broken by an eviction. We don't want to break one hint just to satisfy another. Rename canEvict to shouldEvict, and add the first bit of eviction policy that doesn't depend on spill weights: Always make room in the preferred register as long as the evictees can be split and aren't already assigned to their preferred register. Also make the CSR avoidance more accurate. When looking for a cheaper register it is OK to use a new volatile register. Only CSR aliases that have never been used before should be avoided. llvm-svn: 134735		2011-07-08 20:46:18 +00:00
