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 4402d8652c compiler.cfg.linear-scan: minor fixes 2009-07-05 22:51:53 -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 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
