Slava Pestov e76dce8aff Overflowing fixnum intrinsics now expand into several CFG nodes. This speeds up the common case since only the uncommon case is now a stack syncpoint 2009-07-16 18:29:40 -05:00
Slava Pestov 685e32b091 compiler.cfg.stack-analysis: global optimization work in progress 2009-07-16 16:43:14 -05:00
Slava Pestov 608fb054f2 compiler.cfg: Some code cleanups, update stack-analysis and phi-insertion to work on CFGs with critical edges 2009-07-12 22:22:46 -05:00
Slava Pestov 6810b922ee compiler.cfg: move back-edge? word from stack-analysis to top-level vocab 2009-07-09 23:13:30 -05:00
Slava Pestov 0402790001 compiler.cfg Remove height tracking for ##call instructions, wire in ##no-tco instruction 2009-06-30 21:21:46 -05:00
Slava Pestov 3355fa4809 compiler.cfg.stack-analysis: enable global optimization 2009-06-30 18:11:45 -05:00
Slava Pestov 6e72cf9711 compiler.cfg.stack-analysis: fix another corner case with ##peek insertion, and fix changed-loc merging 2009-06-28 22:52:28 -05:00
Slava Pestov 96baede36a Redesign compiler.cfg.stack-analysis to make compiler.cfg.height redundant, and to fix some problems 2009-06-26 17:29:55 -05:00
Slava Pestov 22fa524db1 compiler.cfg.stack-analysis: split up into three vocabs 2009-06-24 13:54:43 -05:00
Slava Pestov 2c8223fdaf Fix loop handling in stack-analysis 2009-05-31 19:04:26 -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 3e00dc8c8d Start cleaning up stack analysis 2009-05-30 13:22:30 -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
