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 e21ca289c3 compiler.cfg.representations: new pass to make global unboxing decisions, relies on new compiler.cfg.loop-detection pass for loop nesting information 2009-08-08 00:24:46 -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 e0f6d89ff1 compiler.cfg.value-numbering: insert ##copy instructions for instructions whose expressions simplify. While subsequent usages are replaced with the instruction computing the simplified vreg locally, global usages may exist of the original instruction. In this case, the ##copy is not dead 2009-07-24 05:30:30 -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 3fb4fc1bde Improve code generation for shift word: add intrinsics for fixnum-shift-fast in the case where the shift count is not constant, transform 1 swap shift into a more overflow check with open-coded fast case, transform bitand into fixnum-bitand in more cases 2009-07-16 23:50:48 -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 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
