Abdulaziz Ghuloum 1cd2b8acfc * Handling weak-pairs is now generational, fixing performance 
problems when guardians were used to implement hash tables.

Abdulaziz Ghuloum ad118623ec * Added $code-annotation and $set-code-annotation! primops 2007-09-04 19:59:14 -04:00
Abdulaziz Ghuloum 51d512484b * Refixed implementation of guardians to handle dead tconcs 
properly.
 2007-09-01 20:14:05 -04:00
Abdulaziz Ghuloum 95f34409e6 * Slight improvement to the guardians' performance. 2007-09-01 01:21:11 -04:00
Abdulaziz Ghuloum 4daea5e4e0 * Added ikrt_register_guardian_pair to replace ikrt_register_guardian. 2007-09-01 01:00:35 -04:00

Abdulaziz Ghuloum e20576a444 * Added a pcb field "collect_key" that simply gets set to #f 
when garbage collection occurs.

Abdulaziz Ghuloum 28b143036f Added time macro 2007-08-30 11:06:21 -04:00
Abdulaziz Ghuloum bc3e216f63 * transition to non-consing add_one_tconc is done. 
* Performance gains for making a hash table of 10,000,000 elements
  are:
  Before:    47secs       Now:  17secs.
 2007-06-29 01:53:18 +03:00
Abdulaziz Ghuloum 5358680912 * tconc queue now uses 2-words per tconc in the transition to 
non-allocating tconc_add procedure.
 2007-06-29 01:46:27 +03:00
Abdulaziz Ghuloum 41e1859b2b * Fized a bug in the collector that caused tconc pages to never get 
deallocated.  Tconc pages are now allocated from generation 1.
 2007-06-29 01:32:16 +03:00
Abdulaziz Ghuloum 0480517615 * Added floor/ceiling. 2007-06-10 07:32:19 +03:00
Abdulaziz Ghuloum 182de12428 * cleaned up some uses of naked strings in the runtime system. 2007-05-19 14:13:51 -04:00
Abdulaziz Ghuloum 5249a8ec31 * The gc now knows about bytevectors 2007-05-17 04:34:52 -04:00
Abdulaziz Ghuloum 6bdb50004a * incremental step towards loading a fresh compiler for 
bootstrapping.
 2007-05-15 08:56:22 -04:00
Abdulaziz Ghuloum 48e062dfc4 * base-rtd is now placed in the pcb. 
* renamed:
    src/library-manager.ss => src/ikarus.library-manager.ss
 2007-05-05 22:42:26 -04:00
Abdulaziz Ghuloum de7c43a16b * optimized symbol calls using the symbol-function field. 
* added error checks for applying nonprocedures.
 2007-02-25 21:29:28 -05:00
Abdulaziz Ghuloum 819a3ca1c1 * bug in collector causing dirty bits for code objects with younger reloc 
vectors to be unset incorrectly.  The bug was in using || instead
  of | when computing the dirty pattern.
 2007-02-22 21:58:38 -05:00
Abdulaziz Ghuloum d6c2d5dd66 * representation (tags) of bignums/flonums changed successfully. 2007-01-21 20:36:22 -05:00
Abdulaziz Ghuloum 1c37a4ee54 * changing representation for all non-fixnum numbers. 2007-01-21 19:20:37 -05:00
Abdulaziz Ghuloum c8111df150 * fixed bug in handling tcbuckets. 
Summary of the bug:  
    if ik_alloc is called during gc, and if it causes a heap
    overflow, then the pages are deallocated before returning to
    scheme.
 2007-01-19 18:13:44 -05:00
Abdulaziz Ghuloum 13e8f76f13 * intermediate step: 
gc has tcbucket_size=16
  compile allocates tcbucket_size=24
 2007-01-17 14:34:25 -05:00
Abdulaziz Ghuloum a8e1b860bb Live-masks are busted again. 
Some closures that are live are not traced by the GC.
 2006-12-30 22:52:37 +03:00
Abdulaziz Ghuloum 2ea03e0417 * Fixed bug in collecting bignums. 
* time-it now displays the number of collections and bytes
  allocated.
 2006-12-29 13:45:30 +03:00

Abdulaziz Ghuloum b3a6744691 renamed oblist to symbol_table in pcb 2006-12-25 09:28:53 +03:00
Abdulaziz Ghuloum 5ccca042a6 * Implementation of Guardian is complete. 
* Implementation not fully tested.  May have corner cases.

Abdulaziz Ghuloum 3d2d52fe58 Added a guardians field to the pcb.
