Slava Pestov 0612bc6177 Factor source files should not be executable 2009-11-21 17:50:43 -06:00
Slava Pestov b4e36608da compiler.cfg: remove _gc instruction, it doesn't need to exist, and change GC checks to ensure that the right amount of space is available instead of blindly checking for 1Kb 2009-10-05 05:27:49 -05:00
Joe Groff f9695951a0 fold test-vector/branch sequences into a test-vector-branch instruction 2009-10-01 19:53:30 -05:00
Joe Groff 0ea9949e51 split unordered and ordered float comparison intrinsics in compiler; generate only unordered comparisons for now 2009-09-08 17:04:26 -05:00
Slava Pestov cc5476c823 _gc instruction doesn't need slot to hold GC root area size, since that's just tagged-values>> length 2009-08-09 03:08:13 -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 725280d424 Split off the notion of a register representation from a register class 2009-08-07 17:44:50 -05:00
Slava Pestov be363d1a5b compiler.cfg: Get inline GC checks working again, using a dataflow analysis to compute uninitialized stack locations in compiler.cfg.stacks.uninitialized. Re-enable intrinsics which use inline allocation 2009-07-30 09:19:44 -05:00
Slava Pestov cb7735ddf4 compiler.cfg: remove 'regs' slot from instruction tuples now that register allocation doesn't use it anymore 2009-07-29 06:50:46 -05:00
Slava Pestov 8c6b38533c compiler.cfg.linearization: rotate loops. 2x speedup with empty times loop, 1.5x speedup on benchmark.dawes 2009-07-28 21:31:08 -05:00
Slava Pestov ff81b055a5 compiler.cfg.utilities: add loop-entry? word 2009-07-28 08:47:50 -05:00
Slava Pestov d947c61bd7 compiler.cfg.stacks: now performs online local DCN 2009-07-23 20:54:38 -05:00
Slava Pestov 44bcd258f6 Insert _loop-entry in linearization pass instead of in CFG builder, so that optimizations don't have to worry about it 2009-07-22 06:05:17 -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 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 768e2a5148 compiler.cfg: split off condition codes into a comparisons sub-vocabulary 2009-07-13 14:42:52 -05:00
Slava Pestov 8d3a45dee2 compiler.cfg: clean up GC check generation to use spill-slot data type 2009-07-03 23:11:23 -05:00
Slava Pestov 5c6c3ecd85 compiler.cfg.tco: Tail call optimization moved out of compiler.cfg.builder into its own pass 2009-06-30 20:13:35 -05:00
Slava Pestov 2d231f066a GC checks now save and restore registers 2009-06-02 18:23:47 -05:00
Slava Pestov 7dd08892b2 Fix for recent word renaming 2009-06-01 03:19:35 -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 280736ab00 On second thought, linearization will be done after SSA destruction so live-in is accurate 2009-05-29 05:45:40 -05:00

Doug Coleman 3c408342ef renaming: contain? -> any?, deep-contains? -> deep-any?, pad-left -> pad-head, pad-right -> pad-tail, trim-left -> trim-head, trim-right -> trim-tail 2009-01-29 22:19:07 -06:00
Slava Pestov 0021cde743 Fix more compile errors 2008-12-15 22:21:56 -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
