06d30b9fc9 Jump and Throw need to store the term away, if they try to use arena
the term will hang in the stack (#152).

98f79484ae change throw mechanism to fit better with cleanup mechanism:
- balls are now stored off line and recovered by Prolog code when everything
is safe.
- if a ball exists, throw uses the *existing* one (be careful not to have one
laying around).
- Jump routine cleans up every cp except ones for setup_call handling, backtracking simply calls setup handlers.

b72345cc97 handle correctly throws within the scope of a call_cleanup. This is implemented
by using an extra argument to verify if the catcher is the current call_cleanup.
If it is, we allow the exception to go forth.

10c38f8164 1. catch should not catch outside of scope!
2. when we are catching check for the first cleanup we can find; and while
   doing that going on rewinding variables, for SICStus compatibility.

7207c18e65 fix longmp in trow not to recover trail. This way we do not need to do
copy_term/2 and we avoid losing the attributed variable stack.

6046f9f913 more fixes to debugger: make l and s option do what they are supposed to
do.
fix k and t, they had been broken.
Ideas:
DebugOn is now in the system and can disable spypoints.
Have an extra flag to distinguish fast (t,z,k) and slow(l,s) jumping.

8f69c35e7f optime access to execute_cpred 2008-09-01 16:48:05 +01:00
Vítor Santos Costa
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.

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.
