Björn Lindqvist 167d1598b3 compiler.cfg.linear-scan.allocation.*: lots more docs and some word simplifications 2015-04-29 09:31:58 -07:00
Björn Lindqvist d6c1c075ff compiler.cfg.linear-scan.allocation: using slurp-heap 2014-12-15 20:48:34 +01:00
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

Slava Pestov 5b48cd2a63 FFI rewrite part 5: return value boxing and callback parameter boxing now uses vregs; simplify return value unboxing 2010-05-16 03:43:23 -04:00

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 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 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 578b0126fc compiler.cfg.linear-scan: compute-free-pos was broken in the case where more than one inactive interval had the same physical register assigned 2009-06-30 16:07:58 -05:00

Slava Pestov 5c912504d7 compiler.cfg.linear-scan: untangle add-active/delete-active/add-handled calls in spilling, replace 'sort-values last' with 'alist-max' in compiler.utilities 2009-06-19 18:28:30 -05:00

Slava Pestov 669548e62e Clean up some usages of tuck, and add Joe's curried cleave/spread/apply combinators to kernel vocabulary 2009-02-02 13:43:54 -06:00
Slava Pestov 1af3b8ed65 If a register is spilled and the reload location is also a copy, we chicken out and don't coalesce. This is suboptimal but it's not clear to me how to implement it cleanly, and SSA graph coloring will solve this problem eventually anyway 2008-11-04 00:32:56 -06:00
