Slava Pestov 7e35723db0 compiler.tree.propagation: be more careful with intervals, ensuring that the inferred interval of a value is a subset of the value class's interval. This improves accuracy, for example [ >fixnum 1 + >fixnum most-positive-fixnum <= ] constant-folds to true 2009-08-10 01:16:49 -05:00
Slava Pestov 8a9c15ab0b compiler.tree.escape-analysis: if the output of an #introduce node has an immutable tuple class type declaration, and it is not passed to any subroutine calls, or returned from the word, then unbox it. This speeds up vector arithmetic words on specialized arrays, because the specialized array is unboxed up-front, eliminating an indirection on every loop iteration 2009-08-09 16:29:21 -05:00
Slava Pestov cc5476c823 _gc instruction doesn't need slot to hold GC root area size, since that's just tagged-values>> length 2009-08-09 03:08:13 -05:00
Slava Pestov 687454878a compiler.cfg.linearization: change order to fit older unit tests 2009-08-08 23:06:57 -05:00
Slava Pestov e400d80d8b More accurate interval inference for mod, rem, and propagation can now infer intervals in the case where a value might be f. so, [ [ 127 bitand ] [ drop f ] if dup [ 0 >= ] [ not ] if ] now constant-folds down to 't'! 2009-08-08 23:03:45 -05:00
Slava Pestov 61ea749bb6 More accurate interval-mod and interval-rem 2009-08-08 22:01:12 -05:00
Slava Pestov 24a50c8006 compiler.cfg.two-operand: sometimes we can eliminate a copy in the x = y <op> y case 2009-08-08 20:03:42 -05:00
Slava Pestov 55acddef3f compiler.cfg.representation: OK to unbox output of ##load-reference globally 2009-08-08 20:03:13 -05:00
Slava Pestov 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
Slava Pestov 11dc0a23a8 compiler.cfg.ssa.liveness: fix tests 2009-08-08 16:15:45 -05:00
Slava Pestov 1bf8a0cac7 compiler.cfg.representations: emit-conversion should not be private since CSSA construction uses it 2009-08-08 04:13:30 -05:00
Slava Pestov 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
Slava Pestov e21ca289c3 compiler.cfg.representations: new pass to make global unboxing decisions, relies on new compiler.cfg.loop-detection pass for loop nesting information 2009-08-08 00:24:46 -05:00
Slava Pestov 725280d424 Split off the notion of a register representation from a register class 2009-08-07 17:44:50 -05:00
Slava Pestov 370f4c081d 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
Slava Pestov 97ec3ea1b4 compiler.graphviz: add high-level IR call graph rendering 2009-08-05 03:33:06 -05:00

Slava Pestov d20d335447 compiler.cfg.stacks: more accurate deconcatenatization inserts fewer partially redundant ##peeks. 11% improvement on benchmark.beust2, 2% reduction in ##peek and ##replace instructions inserted 2009-08-03 07:08:28 -05:00

Slava Pestov dac7edd2ab compiler.cfg.def-use: remove compute-def-use word, passes have to call compute-defs or compute-uses now; compiler.cfg.ssa.liveness: don't compute dominance and def-use first since destruction does already 2009-08-02 19:12:32 -05:00
