Björn Lindqvist 86d35982ac compiler.cfg.linear-scan.allocation.splitting: better def for split-uses
it seems to be just as fast as the wordier one
2015-09-22 08:52:37 +02:00
Björn Lindqvist 89e261f673 compiler.cfg.linear-scan.ranges: remove the live-range definition and
use integer pairs instead

so instead of ranges being a sequence of live-ranges it is now a
sequence of integer pairs instead. That makes the
compiler.cfg.linear-scan.ranges simpler and easier to generalize

Björn Lindqvist 68c6654763 compiler.cfg.linear-scan.*: move words for splitting and intersecting ranges to the compiler.cfg.linear-scan.ranges vocab 2015-09-22 08:51:04 +02:00
Björn Lindqvist b8d47ed845 compiler.cfg.linear-scan.ranges: new vocab to contain all the range
related stuff from live intervals

Slava Pestov eb802208d1 FFI rewrite part 4: parameter and return value unboxing redesign 2010-05-11 19:11:44 -04:00
Slava Pestov 982e704626 compiler.cfg.linear-scan: clean up clobber-insn handling 2010-05-07 18:22:35 -04:00
Slava Pestov 627295f094 Language change: tuple slot setter words with stack effect ( value object -- ) are now named FOO<< instead of (>>FOO) 2010-05-06 17:21:02 -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
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 5a64290386 compiler.cfg.linear-scan: more code cleanups, and working on split-to-fit algorithm 2009-07-09 00:20:03 -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 64f93e41a9 Various linear scan fixes
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
