Björn Lindqvist 135d7f5ff3 compiler.cfg.*: more unit tests 2015-04-29 09:31:59 -07:00
Björn Lindqvist 992314d2de compiler.cfg.*: new word for consuming deques slurp/replenish-deque
most uses of slurp-deque processes one item and pushes a sequence of
items to continue working with. it can be formalized into a
slurp/replenish-deque combinator which also reduces the amount of
variables you need to use

Björn Lindqvist e5866dfa80 compiler.cfg.*: changed stack effect of needs-predecessors from ( cfg -- cfg') to ( cfg -- ) 2014-12-11 14:30:47 +01:00
Björn Lindqvist d1032c159a compiler.cfg.dataflow-analysis: generic for configuring the "block skipping"
To accurately record uninitialized/overinitialized stack locations,
kill blocks needs to be analyzed. Now you can make it so by overriding
ignore-block?.

Doug Coleman 76580da5d5 Refactor the lexer/parser to expose friendlier words for scanning tokens. The preferred top-level words now throw an exception on EOF.
CREATE -> scan-new
CREATE-CLASS -> scan-new-class
CREATE-WORD -> scan-new-word
CREATE-GENERIC -> scan-new-generic
scan -> (scan-token)
scan-token now throws on eof
(scan-word) returns word/number/f
scan-word now throws on eof
scan-word-name expects a non-number
Fixes #183.
Fixes #209.

Slava Pestov c211c3e84e FFI rewrite part 1: split up ##alien-invoke and friends into smaller instructions 2010-05-09 21:36:52 -04:00
Slava Pestov 5197aca215 compiler.cfg.dataflow-analysis: when intersecting sets, treat uninitialized sets as universal rather than empty; reduces number of stack instructions generated by 1% 2009-08-20 18:15:41 -05:00
Daniel Ehrenberg d35e1eb76c Fixing write-barrier elimination; adding bb as a parameter to join-sets in dataflow analysis 2009-08-12 23:52:29 -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 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 2009-07-22 03:08:28 -05:00
