Björn Lindqvist 0c2559ef6e compiler.*: a bunch more compiler docs 2015-05-09 20:04:22 -07:00
John Benediktsson c65877104e compiler: cleanup usings. 2014-12-13 16:10:21 -08:00
Björn Lindqvist 8744d908b6 compiler.cfg.*: fix stack effect of compiler passes in optimize-cfg
since they all modify the cfg in place, it is better if their stack
effect is ( cfg -- ) instead of ( cfg -- cfg' )
2014-12-11 14:30:45 +01:00
Björn Lindqvist 971a157369 compiler.cfg.instructions: ##alien-assembly should be in the alien-call-insn union but not gc-map-insn 2014-12-08 18:13:46 -08:00
John Benediktsson 5908186301 compiler.cfg.alias-analysis: use clear-set. 2013-03-07 21:35:00 -08:00
John Benediktsson 4e72d80256 Using "same?" in more places. 2012-07-21 10:22:44 -07:00
Slava Pestov 910748819d Now that #foo and ##foo are symbols we can remove a bunch of \ 2011-11-12 22:04:26 -08:00

Slava Pestov a605d5c9c9 compiler.cfg.alias-analysis: dead store elimination was too aggressive, can't eliminate dead stores across a GC call even for fresh allocations because GC will see uninitialized data 2010-09-06 16:57:56 -07:00
Slava Pestov b6fe62299e compiler.cfg.alias-analysis: factor-call-insns which defined values were not handled properly 2010-07-19 19:56:00 -04:00

Slava Pestov f14f2cbdab compiler.cfg.value-numbering: merge 'simplify' pass into 'rewrite' 2010-05-03 17:34:08 -04:00
Slava Pestov 5d3a7a7362 Untagged fixnums work in progress 2010-05-03 17:34:02 -04:00
Slava Pestov 503c0fcfde compiler: Start using tagged-rep for stuff, and split up compiler.cfg.representations into several sub-vocabularies 2010-05-03 17:34:01 -04:00
Slava Pestov 2aaf24412a compiler: change how 'f' is represented in low level IR to simplify some code, and fuse a ##load-constant of a word with a ##compare into a ##compare-imm on x86-32. This eliminates a spill from binary-search 2010-04-18 21:42:45 -05:00
Slava Pestov eceabbc57e compiler: new set-special-object intrinsic; more efficient special-object intrinsic 2010-04-01 20:09:14 -04:00

Slava Pestov e4ad642134 vm: 4 bit tags, new representation of alien objects makes unbox-any-c-ptr more efficient (work in progress) 2009-11-02 04:25:54 -06:00
Slava Pestov fb09d67936 compiler.cfg.alias-analysis: fix ##compare where operands are copies 2009-10-01 23:54:19 -05:00
Slava Pestov 2a4475f85e Fix alias analysis of a ##compare whose input is another ##compare 2009-10-01 23:20:05 -05:00
Slava Pestov 31f39ce32f compiler.cfg.alias-analysis: optimize ##vm-field-ptr and ##alien-global instructions, and optimize out ##compare between values of different alias classes; this optimizes '[ [ >float ] bi@ [ + ] [ - ] 2bi eq? ]' down to an o-op and removes boxing from '[ [ >float ] bi@ [ + ] [ - ] 2bi = ]' 2009-10-01 23:03:17 -05:00
Phil Dawes 84faf2431f cleaned up vm-field-ptr compiler code 2009-09-24 08:16:57 +01:00
Phil Dawes ff8f2b10ec fixed up getenv compiler intrinsic to use vm struct userenv 2009-09-16 08:16:32 +01:00
Slava Pestov 85a2bfab6c compiler: eliminate boilerplate by centralizing info in declarative INSN: syntax 2009-09-02 06:22:37 -05:00
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 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 725280d424 Split off the notion of a register representation from a register class 2009-08-07 17:44:50 -05:00
Slava Pestov 89db2e745d 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
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
Slava Pestov 9e987e8642 Merge branch 'master' into global_optimization 2009-06-01 03:12:32 -05:00
Slava Pestov 692b479302 Split off local-optimization combinator into compiler.cfg.local, factor out CFG -> MR into compiler.cfg.mr, split off GC check insertion into a new compiler.cfg.gc-checks pass 2009-05-31 12:20:46 -05:00
Slava Pestov e04df76f60 Various codegen improvements:
- new-insn word to construct instructions
- cache RPO in the CFG
- re-organize low-level optimizer so that MR is built after register allocation
- register allocation now stores instruction numbers in the instructions themselves
- split defs-vregs into defs-vregs and temp-vregs

Slava Pestov 76d74c16af Fixing various bugs; alias analysis wasn't handling ##phi nodes, stack analysis incorrectly handled height-changing back edges and ##fixnum-*, clean up ##dispatch generation 2009-05-29 01:39:14 -05:00
Slava Pestov ceb332f596 compiler.cfg.alias-analysis: ##peek needs to set alias class of output value 2009-05-28 18:19:01 -05:00
Slava Pestov 1fa465d77f Fix alias analysis 2009-05-28 02:48:58 -05:00
Slava Pestov 3b79d61496 Add a new ##allocation union to remove some code duplication 2009-05-27 18:55:49 -05:00

Doug Coleman 407377fc98 rename peek -> last and update all usages 2009-05-25 16:38:33 -05:00
Slava Pestov 44bfff7c7b Rename ##load-indirect to ##load-reference since this is more descriptive; value numbering doesn't assign expressions to ##load-reference nodes since this would end up folding literals which were eq? but not = 2009-01-29 01:44:58 -06:00
Slava Pestov daf2857d7b define-inline now takes an effect parameter
C: now sets the stack effect of the new word to slot names
add new basis/constants vocab; CONSTANT: foo bar is equivalent to : foo bar ; inline
(going to fold CONSTANT:, ALIAS: and qualified into core soon perhaps)
tighten the screws: inline words now need a stack declaration too
update some usages of inline words
