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 e6f5eab598 compiler.cfg.linear-scan: fix resolve pass 2009-07-28 08:47:35 -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 a452f32e3a compiler.cfg.linear-scan: Get cycle breaking in resolve pass to work by allocating a spare spill slot for this purpose 2009-07-05 21:32:23 -05:00
