Slava Pestov 2517b2fc2b compiler: combine ##load-constant followed by ##alien-double into a ##load-double on x86-32, saving an integer register 2010-04-18 21:42:45 -05:00
Slava Pestov bc9241d2b7 compiler.tree.propagation.recursive: more fine-grained generalize-counter-interval eliminates overflow checks from binary-search 2010-04-18 21:42:45 -05:00
Daniel Ehrenberg 8e227bc874 Propagation tracks length just like any other read-only slot 2010-03-09 15:58:44 -05:00
Joe Groff 00ce8b6a33 deprimitivize tuck and put it to pasture 2009-11-05 22:47:05 -06:00
Doug Coleman 3f3d57032b Delete empty unit tests files, remove 1- and 1+, reorder IN: lines in a lot of places, minor refactoring 2009-08-13 19:21:44 -05:00
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 c3d60e5899 compiler.tree.recursive: more accurate loop detection 2009-08-04 19:18:40 -05:00
sheeple a4e62dfdba Fix for math.parser syntax change 2009-04-13 14:47:39 -05:00
Slava Pestov 4fdb5d0557 Fix infinite fixed point iteration bug found by littledan; generalize-counter-interval wasn't called in all the right places 2009-03-12 17:30:24 -05:00
Slava Pestov 6b25e99470 Add summary for heaps more vocabs 2009-02-16 21:05:13 -06:00
Slava Pestov fa6a2047f0 New inlining heuristic: number of usages within this word. Speeds up bootstrap by 10% 2008-12-04 07:05:59 -06:00
Slava Pestov f04b32ea02 Remove duplicated logic 2008-11-11 09:10:33 -06:00
Slava Pestov 5f4b247072 Propagation pass now uses a stack of hashtables for predicated constraints instead of cloning a hashtable. New strategy for recursive propagation; now converges with fewer iterations. ~15 sec bootstrap time improvement 2008-11-11 08:49:00 -06:00
Slava Pestov 40da49bef5 Perform loop detection before normalization, clean up normalization pass, more aggressive recursive return value propagation. Fixes regression on nsieve benchmark 2008-09-12 05:17:27 -05:00
Slava Pestov 8c46a3d56f Only annotate certain nodes ith value info 2008-08-24 14:02:33 -05:00
Slava Pestov 9aa6d8ae04 Compiler fixes 2008-08-22 15:30:57 -05:00
Slava Pestov 9b6fb70eba Debugging optimizer 2008-08-18 15:47:49 -05:00
Slava Pestov e1987d4af9 Debugging new optimizer 2008-08-14 23:35:19 -05:00
Slava Pestov f2a5a30c6f New front-end and high-level optimizer lands 2008-08-12 03:22:45 -05:00
