Slava Pestov 810cd7b4bb compiler.cfg.ssa.destruction: don't coalesce registers with different representations, even if they're in the same register class, since this messes up spilling		2009-09-29 22:28:20 -05:00

construction	compiler.cfg: new system to track when results of analyses need to be recomputed (reverse post order, linear order, predecessors, dominance, loops). Passes can now call needs-predecessors, needs-dominance, needs-loops at the beginning, and cfg-changed, predecessors-changd at the end. Linearization order now takes loop nesting into account, and linear scan now uses linearization order instead of RPO.	2009-08-08 20:02:56 -05:00
