Slava Pestov b28619ce2f vm: minor GC traces embedded pointers 2009-11-22 13:37:39 -06:00
Doug Coleman 6f7ec206a1 rename millis to system-millis, micros to system-micros, add nano-count 2009-11-18 15:58:48 -06:00
Slava Pestov 2c8f67851e vm: fix GC safety issue in callers of unbox_array_size(), and change how disable-gc-events works so that it doesn't make a byte array that's too large 2009-11-11 05:21:03 -06:00
Slava Pestov 064c00f78d New identity-hashcode primitive 2009-11-10 21:18:54 -06:00
Slava Pestov 43e08c76fb vm: on 32-bit, the largest free block size was only 512mb, leading to weird errors if the heap grew beyond this. eliminate this limit 2009-11-06 08:44:36 -06:00

Slava Pestov e2107166ff vm: restructure data_roots so that its a sequence of handle/len pairs rather than just handles, use it in inline_gc() and all_instances() so that we don't run out of heap while building the object array 2009-11-06 00:54:28 -06:00
Slava Pestov 72ab6ec548 vm: rewrite 'become' primitive so that it uses a slot visitor instead of GC 2009-11-05 19:03:51 -06:00

Slava Pestov 6c2c87758a vm: rename gc_root to data_root, add code_root to fix a problem where code blocks would move underneath the PIC compiler if PIC compiler allocated enough 2009-11-02 18:10:34 -06:00

Slava Pestov 7cbaf3e0a3 vm: don't do a data compaction when growing the data heap, speeds up data heap grow by a bit 2009-10-31 21:06:34 -05:00
Slava Pestov b2ba465bcd Merge optimizations from master branch 2009-10-31 03:02:19 -05:00
Slava Pestov 793d0606f6 vm: various minor optimizations speeding up gc0 and dispatch1 benchmarks, as well as bootstrap
- make allot_object() inline, move slow case to allot_large_object()
- reduce number of conditional branches in megamorphic cache miss handler
- make unbox_array_size() inline, move slow case to unbox_array_size_slow()
- new memset_cell() function uses memset_pattern4/8() on Mac OS X

Slava Pestov 5536003cf8 vm: new GC policy: mark sweep after N megabytes promoted, mark compact if tenured space cannot fit nursery+aging in one contiguous block. N = 32 on 32-bit and 64 on 64-bit 2009-10-30 02:26:57 -05:00

Slava Pestov 70dcecf61a vm: don't flush instruction cache twice per code block on a major GC on PowerPC 2009-10-15 22:31:41 -05:00
Slava Pestov 45eb68fa38 vm: during tenuring stage of aging collection, if tenured space fills up, it would attempt a to_tenured collection. this will succeed if all roots were tenured. however, this is unsound, because there's now an untraced segment of tenured space. fix: if tenuring fails, go on to do a full collection instead 2009-10-15 05:51:11 -05:00
Phil Dawes 7fef05fd76 Removed VM_PTR macros. All builds reentrant by default 2009-10-14 19:14:57 +01:00
