3d6e223dae support for space reservation (goal: call gc before trying to insert very large terms). 2010-08-02 13:04:30 +01:00

e122f2ca8d Global trie support: atomic terms (vars, integers and atoms) are now stored 
in the local tries (and not in the global trie). This required major changes
to the trie instructions in order to unify the use of the auxiliary stack
organization for the terms in the local tries and in the global trie.

df2b11a6ec define Optype for xxc, for instructions whose constant argument is a term, like functor(a,X,T). 2009-12-06 00:37:48 +00:00

5e4d7078ab support for trie compact lists (version 2): this new version uses 
different marks to distinguish the lists ending with the empty list
from the lists ending with a non-empty list term.

828964c3c1 remove optimised arithmetic instructions. They made the emulator even bigger than 
usual, and they were not performing.

d70cb39c1d fix answer_trie compilation and execution: 
- YapOpcodes.h should have do/trust/try/trust: force this order in
tab.tries.insts.i
- retry and trust instructions should not trust YENV

fdf762e326 push changes to make tabling work: don't ignore tabling and yapor fields 
in optype.

2a84e259a2 Upgrade to new CHR (with Jan's changes). 
Found out I need to add an extra field to allocate so that the
exception handling code knows where the clause is.
Protect creep_allowed from NULL pointers.

1226b58d8e The debugger relied on the environment stack. To fix it: 
- absmi.c now tells who called the debugger, besides who it was calling
- this is used to control whether we allow a goal to be debugged.
- I have creep to start creeping immediately, and signal_creep to tell
  the next meta-call to creep what it executes!
- The debugger uses CalledFromTheDebugger to know if it is within the
debugger. If so, we do not need to creep on leaving.

d636450512 more fixes to make rclause.h automatic: 
define new type n for Integers, as they were mistaken for Term.
 define early return cases and ifdef exceptions.

17ba194c1e Include new instruction execute_cpred to perform tail optimisation for 
builtins. Required changes:
- be careful about creeping in deallocate: it may be followed by
something that is not a cut nor a proceed.
- include new instruction in absmi.c: it is a merge of execute and
call_cpred.
- change compiler to generate execute even for C builtins.
- be careful with dexecute: it may not be done if execute_op is a C
builtin.
- if we are in execute_cpred, the garbage collector cannot trust P:
instead it must look at CP to find out the size of the current
environment. The macro gc_P receives that information.
- We don't need to change CP if we do a meta-call from within
execute_cpred (and we in fact cannot). Check places where we do
meta-calls: exec, clause in cdmgr, and lu_recorded.
