Slava Pestov 370f4c081d compiler.cfg: convert code into two-operand form before SSA destruction; SSA destruction now operates on a relaxed SSA form where multiple defs of the same vreg are allowed, but only within a single basic block. This makes linear scan's coalescing redundant, allowing it to be removed completely 2009-08-05 18:57:46 -05:00
Slava Pestov c1c8424605 Compiler speedups 2009-08-02 09:16:21 -05:00
Slava Pestov e1c7f7394a compiler.cfg: clean up unit tests using some new utilities 2009-08-02 03:49:25 -05:00
Slava Pestov 791fbe4003 compiler.cfg.linear-scan: fix case where a register can be made available for only a part of a live interval's lifetime, but there are no more usages after the split location. This case never came up until global stack analysis, at which point it started to be exercised on x86-32 2009-07-30 02:13:30 -05:00
Slava Pestov cb36a40dc4 compiler.cfg.linear-scan: more test fixes 2009-07-29 07:04:52 -05:00

Slava Pestov 74766d1ccd compiler.cfg.linear-scan.assignment: modifies instructions in place instead of storing a registers assoc for further compile-time performance improvement 2009-07-29 06:36:14 -05:00

Slava Pestov d913d7331f compiler.cfg: Minor optimization. Instructions can now only ever produce a single value; this eliminates 1array constructions and some iterations 2009-07-28 12:29:07 -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
