Björn Lindqvist 5cd44dc07c compiler.cfg.linear-scan.allocation.state: set spill-area-size/align when the cfg tuple is created 2015-04-29 09:31:57 -07:00

John Benediktsson 2a893a110a compiler.cfg.linear-scan.allocation.state: don't use slot.syntax. 2014-12-15 13:10:59 -08:00
Björn Lindqvist 35d00da765 compiler.cfg.linear-scan.allocation.*: maybe a fix for #1227
The register allocator pops from the unhandled-intervals and
unhandled-sync-points heaps. If two live intervals share the same
start slot, then they can be popped in either order leading to
differently generated code. So instead use one
heap (unhandled-min-heap) and both the start and end slot as the heap
key to resolve tie-breakers

Joe Groff 2bd6de9a02 slots: pre-create the "at", "nth", and "global" slots to make deterministic the currently nondeterministic ambiguity between accessors:change-* and assocs:change-at, sequences:change-nth, and namespaces:change-global 2011-09-19 10:03:43 -07:00
Slava Pestov e27adb2830 compiler: re-architect low-level optimizer to allow more than one output value per instruction 2010-07-13 07:40:14 -04:00
Slava Pestov ba7cb61133 Stack allocation improvements
- New with-out-parameters combinator
- Inhibit tail call optimization in frames with local allocation, to ensure that passing a stack allocated value to the last word in the quotation works
- local allocations are now aligned properly
- spill slots are now aligned properly aligned in frames which have parameter and local allocation areas

Slava Pestov f5c5d8b44c compiler: remove flat machine representation and generate code directly from the CFG 2010-05-03 17:34:32 -04:00
Slava Pestov ffd1844d52 compiler.cfg.linear-scan: clean up spill slot assignment 2010-05-03 17:34:24 -04:00
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 1d872db58d compiler.cfg.linear-scan: tweak it so that register allocation does not depend on hashing order 2009-09-27 23:29:48 -05:00
Slava Pestov 705b4ab5c3 compiler.cfg.linear-scan: fix partial sync point logic in case where dst == src, and clean up spilling code 2009-09-27 19:28:20 -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 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 dea872c7e3 compiler.cfg.linear-scan.allocation: fix broken spill slot reuse logic 2009-07-10 00:25:46 -05:00
Slava Pestov d02854b04e compiler.cfg.linear-scan: two live intervals which are coalesced will use the same spill slot 2009-07-09 23:12:49 -05:00
Slava Pestov e2044602aa compiler.cfg.linear-scan: debugging spilling, add more assertions 2009-07-07 13:01:27 -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 d07c0429fc compiler.cfg.linear-scan: assign spill slots to vregs globally, so that resolve pass never has to perform a memory->memory transfer 2009-07-03 22:51:40 -05:00
Slava Pestov 1f5f8393c3 compiler.cfg.linear-scan: Further progress on inactive interval handling 2009-06-17 15:27:20 -05:00
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
