Björn Lindqvist 043b6d5377 compiler.cfg.linear-scan.linear-scan: refactoring of word so that locals doesn't need to be used and more docs (by moving comments) 2015-04-29 09:31:56 -07:00
John Benediktsson c65877104e compiler: cleanup usings. 2014-12-13 16:10:21 -08:00
John Benediktsson 068ddd6c7b compiler: cleanup cfg passes to have stack effect ( cfg -- ) 2014-12-11 12:48:43 -08:00
Björn Lindqvist 476ebf5b25 compiler.cfg.*: more docs, tests and a small refactoring of the
admissible-registers word

Joe Groff 2bd6de9a02 slots: pre-create the "at", "nth", and "global" slots to make deterministic the currently nondeterministic ambiguity between accessors:change-* and assocs:change-at, sequences:change-nth, and namespaces:change-global 2011-09-19 10:03:43 -07:00
Slava Pestov 0955f2c7eb compiler.cfg.linear-scan: fix typo 2010-05-17 05:50:13 -04:00
Slava Pestov 3f8e13bf66 compiler.cfg: refactor stack frame code and fix frame pointer usage in callbacks 2010-05-16 21:04:40 -04:00
Slava Pestov 43f269e4eb Register allocation now uses SSA properties to coalesce values with different representations 2010-05-03 17:34:20 -04:00
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 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 857ef94acc compiler.cfg.linear-scan: use compiler.cfg.parallel-copy in resolve pass 2009-07-28 07:39:46 -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 8ff473e42c compiler.cfg.linear-scan.resolve: get it to work on CFGs with critical edges 2009-07-12 23:00:33 -05:00
Slava Pestov c20e6c290f compiler.cfg.linear-scan: split off parallel mapping code from resolve pass, use it in assignment pass to resolve parallel copies 2009-07-08 23:07:06 -05:00
Slava Pestov e2044602aa compiler.cfg.linear-scan: debugging spilling, add more assertions 2009-07-07 13:01:27 -05:00

Slava Pestov d0f6a7d048 Split up compiler.cfg.linear-scan.allocation into a number of sub-vocabularies; start work on compiler.cfg.linear-scan.resolve; start work on inactive interval splitting 2009-06-11 17:55:14 -05:00
Slava Pestov 04c72d0a72 Linear scan: correctly compute live spill slots 2009-06-05 18:06:47 -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
