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

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

FFI rewrite part 5: return value boxing and callback parameter boxing now uses vregs; simplify return value unboxing

Register allocation now uses SSA properties to coalesce values with different representations

compiler.cfg.linear-scan: tweak it so that register allocation does not depend on hashing order

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
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

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

Split off the notion of a register representation from a register class
2009-08-07 17:44:50 -05:00
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
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

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
