live-ranges	compiler.cfg.ssa.destruction: more aggressive coalescing work in progress	2009-09-27 17:17:26 -05:00
interference-tests.factor	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
interference.factor	compiler.cfg: convert code into two-operand form before SSA destruction; SSA destruction now operates on a relaxed SSA form where multiple defs of the same vreg are allowed, but only within a single basic block. This makes linear scan's coalescing redundant, allowing it to be removed completely	2009-08-05 18:57:46 -05:00
