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.

/*
|
|
*
|
|
* This file works together with pl/arrays.yap and arrays.h.
|
|
*
|
|
* YAP now supports a very simple notion of arrays. Arrays may be
|
|
* allocated dynamically or statically:
|
|
*
|
|
* o anonymous arrays are created during execution and allocated
|
|
* in the heap. They have the lifetime of any other other heap
|
|
* object. Any term can be an argument to a dynamic array.
|
|
*
|
|
* Dynamic arrays are named as a free variable and are
|
|
* initialised with free variables.
|
|
*
|
|
* o named arrays are created during execution but allocated
|
|
* in the code space. They have the lifetime of an heap
|
|
* object. Any term can be an argument to a dynamic array.
|
|
*
|
|
* Named arrays are named with atoms and are initialised with
|
|
* free variables.
|
|
*
|
|
* o static arrays are allocated in the heap. Their space is
|
|
* never recovered unless explictly said so by the
|
|
* program. Arguments to these arrays must have fixed size,
|
|
* and can only be atomic (at least for now).
|
|
*
|
|
* Static arrays can be named through an atom. They are
|
|
* initialised with [].
|
|
*
|
|
* Users create arrays by a declaration X array Arity. If X is an atom
|
|
* A, then this it is a static array and A's the array name, otherwise
|
|
* X refers to a dynamic array.
|
|
*
|
|
* As in C, arrays start counting from 0.
|
|
*
|
|
* Users access arrays by a token X[I] or a[I], this token can appear
|
|
* anywhere within the computation, so a[2] = X[3*4] means that the
|
|
* second element of global array a should unify with the 12th element
|
|
* of array X. The mechanism used to implement this is the same
|
|
* mechanism used to implement suspension variables.
|
|
*
|
|
* Representation:
|
|
*
|
|
* Dynamic Arrays are represented as a compound term of arity N, where
|
|
* N is the size of the array. Even so, I will not include array bound
|
|
* checking for now.
|
|
*
|
|
* |--------------------------------------------------------------|
|
|
* | $ARRAY/N|....
|
|
* |______________________________________________________________
|
|
*
|
|
*
|
|
* Unbound Var is used as a place to point to.
|
|
*
|
|
* Static Arrays are represented as a special property for an atom,
|
|
* with field size and
|
|
*
|
|
* A term of the form X[I] is represented as a Reference pointing to
|
|
* the compound term:
|
|
*
|
|
* '$array_arg'(X,I)
|
|
*
|
|
* Dereferecing will automatically find X[I].
|
|
*
|
|
* The only exception is the compiler, which uses a different
|
|
* dereferencing routine. The clause cl(a[2], Y[X], Y) will be
|
|
* compiled as:
|
|
*
|
|
* cl(A, B, Y) :- '$access_array'(a, A, 2), '$access_array'(Y, B, X).
|
|
*
|
|
* There are three operations to access arrays:
|
|
*
|
|
* X[I] = A, This is normal unification.
|
|
*
|
|
* X[I] := A, This is multiassignment, and therefore
|
|
* backtrackable.
|
|
*
|
|
* X[I] ::= A, This is non-backtrackable multiassignment, ans most
|
|
* useful for static arrays.
|
|
*
|
|
* The LHS of := and of ::= must be an array element!
|
