2007-04-17Copy coalescing change to prevent a physical register from being pin to aEvan Cheng
long live interval that has low usage density. 1. Change order of coalescing to join physical registers with virtual registers first before virtual register intervals become too long. 2. Check size and usage density to determine if it's worthwhile to join. 3. If joining is aborted, assign virtual register live interval allocation preference field to the physical register. 4.
