Slava Pestov 43f269e4eb Register allocation now uses SSA properties to coalesce values with different representations 2010-05-03 17:34:20 -04:00
Slava Pestov 9b34a4a054 compiler.cfg: remove unused 'reps' slot from compiler.cfg, and re-organize things in preparation for SSA register allocation 2010-05-03 17:34:18 -04:00
Slava Pestov 43fc230c69 compiler.cfg.linear-scan: cleanups 2010-05-03 17:34:18 -04:00

Slava Pestov 51b13ce373 compiler.cfg.linear-scan: don't insert a _reload if the register is going to be overwritten anyway 2010-05-03 17:34:14 -04:00
Doug Coleman 1476cdb974 reverse-here -> reverse! 2009-10-28 14:40:15 -05:00
Slava Pestov 447c5fbf7a compiler.cfg.linear-scan.live-intervals: dead-value-error is never thrown anymore 2009-08-30 05:15:18 -05:00
Slava Pestov 0db01f6d5f compiler.cfg.linear-scan now supports partial sync-points where all registers are spilled; taking advantage of this, there are new trigonometric intrinsics which yield a 2x performance boost on benchmark.struct-arrays and a 25% boost on benchmark.partial-sums 2009-08-30 04:52:01 -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 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 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 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

Slava Pestov 0bcf4ce535 compiler.cfg.linear-scan: Re-implement spilling, add some additional runtime assertions, simplify assignment pass since it doesn't have to track spill slots anymore; just assume a live value that's not in active or inactive is spilled 2009-07-07 03:28:55 -05:00
Slava Pestov 4402d8652c compiler.cfg.linear-scan: minor fixes 2009-07-05 22:51:53 -05:00

insert spill before reload to fix x86-32 regression
inactive splitting: if all inactive intervals' registers are in use, don't fail
fix stack analysis tests

Slava Pestov d0f6a7d048 Split up compiler.cfg.linear-scan.allocation into a number of sub-vocabularies; start work on compiler.cfg.linear-scan.resolve; start work on inactive interval splitting 2009-06-11 17:55:14 -05:00
Slava Pestov 81b2a39070 compiler.cfg.linear-scan: re-do interval splitting to operate on live ranges; add inactive set processing 2009-06-04 18:53:02 -05:00
