|
|
*
|
|
* Revision 1.32 2005/07/06 19:34:11 ricroc
|
|
* TABLING: answers for completed calls can now be obtained by loading (new option) or executing (default) them from the trie data structure.

|
* Revision 1.27 2005/06/01 14:02:52 vsc
|
|
* get_rid of try_me?, retry_me? and trust_me? instructions: they are not
|
|
* significantly used nowadays.
|
|
*
|
|
* Revision 1.26 2005/04/10 04:01:13 vsc
|
|
* bug fixes, I hope!

|
|
* More bug fixes for overflow handling
|
|
*
|

* Revision 1.24 2004/09/27 20:45:04 vsc
|
|
* Mega clauses
|
|
* Fixes to sizeof(expand_clauses) which was being overestimated
|
|
* Fixes to profiling+indexing
|
|
* Fixes to reallocation of memory after restoring
|
|
* Make sure all clauses, even for C, end in _Ystop
|
|
* Don't reuse space for Streams
|
|
* Fix Stream_F on StreaNo+1
|
|
*
|
|

* trim_trail for default machine
|
|
* be more aggressive about try-retry-trust chains.
|
|
* - handle cases where block starts with a wait
|
|
* - don't use _killed instructions, just let the thing rot by itself.
|
|
*
|
|
* Revision 1.21 2004/03/10 14:59:55 vsc
