compiler.cfg.liveness: merge in compiler.cfg.liveness.ssa and simplify the code, since we don't compute live sets before SSA construction anymore

Register allocation now uses SSA properties to coalesce values with different representations

compiler.cfg: remove _gc instruction, it doesn't need to exist, and change GC checks to ensure that the right amount of space is available instead of blindly checking for 1Kb
2009-10-05 05:27:49 -05:00
705b4ab5c3
compiler.cfg.linear-scan: fix partial sync point logic in case where dst == src, and clean up spilling code
2009-09-27 19:28:20 -05:00
513ba1f176
compiler.cfg.linearization.order: basic blocks were being inserted twice if some blocks had repeated successors, causing problems for register allocation

compiler: eliminate boilerplate by centralizing info in declarative INSN: syntax
2009-09-02 06:22:37 -05:00
0db01f6d5f
compiler.cfg.linear-scan now supports partial sync-points where all registers are spilled; taking advantage of this, there are new trigonometric intrinsics which yield a 2x performance boost on benchmark.struct-arrays and a 25% boost on benchmark.partial-sums
2009-08-30 04:52:01 -05:00
d0c393aa60
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
4b7ba38aab
compiler.cfg: virtual registers are integers now, and representations are stored off to the side. Fix bug in representation selection that would manifest if a value was used as a float and a fixnum in different branches; cannot globally unbox float in this case
2009-08-08 04:02:18 -05:00

compiler.cfg: Minor optimization. Instructions can now only ever produce a single value; this eliminates 1array constructions and some iterations

compiler.cfg.linear-scan: use compiler.cfg.parallel-copy in resolve pass

Move liveness back to compiler.cfg.liveness, fix a corner-case where it didn't work on some forms of non-SSA code
2009-07-22 06:07:28 -05:00
21a012e3d7
compiler.cfg: Major restructuring -- do not compute liveness before local optimization, and instead change local optimizations to be more permissive of undefined values. Now, liveness is only computed once, after phi elimination and before register allocation. This means liveness analysis does not need to take phi nodes into account and can now use the new compiler.cfg.dataflow-analysis framework

compiler.cfg.linear-scan: Re-implement spilling, add some additional runtime assertions, simplify assignment pass since it doesn't have to track spill slots anymore; just assume a live value that's not in active or inactive is spilled
