<LI> FIXED: more improvements to Eval.
|
|
<LI> NEW: predicate_property(X,public).
|

<LI> NEW: public/1 directive, handling of source was cleaned up
|
|
(it used to be broken if one would switch between source and

amount of testing for other cases.
|

|
interface to the current input for their own dubious purposes.
|

<LI> NEW: yap_flag(discontiguous_warnings, single_var_warnings,
|
|
redefine_warnings) as in SICStus. This should eventually

replace style_check and no_style_check.

|
full meta-call, and a system catch, that uses $execute0 and
|
|
$mod_switch and that should be only used deep within the bowels
|
|
of the system.

expanded by inner meta-calls.

prolog_initialize/1 for SICStus Prolog code.

<LI> FIXED: don't explode if the compiler finds too many
|
|
variables or if there is not enough code space to store our code.

<LI> FIXED: remove limit on size of strings and quoted atoms.
|

<LI> FIXED: [ ] is now parsed as [], like other Prologs do.

|
<LI> SYNCH: with Ricardo Rocha's optyap. SBA is broken.

<LI> FIXED: reverse_opcode_lookup table.
|
|
<LI> NEW: YAP as a library,
|
|
<UL>
|
|
<LI> New functions provide an interface for initialising
|
|
and calling Yap from external environments. Note that Yap
|
|
is still a big chunk.
|
|
<LI> Restoring embedded C-functions is now performed by
|
|
restore_heap together with InitStaff.
|
|
<LI> The code to restore a clause has been updated to use
|
|
yamop and GONEXT. The same code does both indices and clauses.
|
|
<LI> All macros that adjust pointers are now functions,
|
|
and type-check their arguments.
|
|
<LI> All functions that restore a stack (from restore,
|
|
growheap and growlocal) have now been merged in a general
|
|
function in grow.c. This decreases efficiency slightly, but
|
|
should improve maintainability.
|
|
<LI> InitStaff() now has an argument saying whether we are
|
|
calling from boot or from restore. Note that most Prolog
|
|
executions will actually call InitStaff() twice.
|
|
<LI> initialisation code in yap.c was simplified. Several
|
|
functions and variables were moved out to init.c.
|
|
<LI> routines that start new goals were moved out of
|
|
cdmgr.c to exec.c.

|
|
save_program.

<LI> FIXED: allow (call(X), X) to possibly succeed. It is
|
|
unclear whether that conforms to the ISO standard, but there
|
|
is the excuse it is SICStus compatible.

<LI> FIXED: $undefp would call a bad $user_call.

callable/1, and simple/1.

including support for tabulation.

multi-assignment variables even if they were not heap

<LI> FIXED: garbage collector was following list of suspended
|
|
goals as if a variable.
|
|
<LI> FIXED: call/1 was not importing modules correctly.
|
|
<LI> NEW: A library. Right now it just consists of
|
|
several files copied from the Edinburg Prolog library, with
|
|
little or no change. To use it, you must do "make install" or
|
|
have LIBDIR in the Makefile set to the YAP source directory.
|
|
<LI> FIXED: garbage in debugger.
|
|
<LI> FIXED: fix writing \+ (a,b) properly.
|
|
<LI> NEW: get rid of addresses for the unify() routines. Unify
|
|
now receives values, as it should, instead of addresses.
|
|
<LI> NEW: get rid of the representant stuff for
|
|
coroutining. Instead of trying to find out if we bound an
|
|
external variable, from now on we must guarantee that we
|
|
pass a non-dereferenced external variable (e.g. argument) to
|
|
the unification routine, otherwise delayed variables may not
|
|
wake up.
|

<LI> FIXED: get rid of bind_variable.

ignore depth limits.

|
|
by ErCl or ErDBE.

confusing the parser.
|

|
<LI> FIXED: make the system more robust when it can't get more
|
|
memory.
|
|
<LI> FIXED: recorded with unbounded key was crashing.
|
|
<LI> CLEANUP: use derefa when we know the possible address for
|
|
a variable. This avoids reading a memory cell twice.
|
|
<LI> CLEANUP: make sockets a special stream, make actual
|
|
reading and writing on sockets work, unify all close
|
|
operations on sockets, update iopreds to take special care of
|
|
sockets. Still not working: ungetc on sockets, eof has not
|

been tested.

|
<LI> CLEANUP: conditions on c-interface.
|

<LI> FIXED: growheap could be called with wrong local stack pointer.

|
|

|
|
<LI> FIXED: bug in frozen/2 and friends.
|
|
<LI> CLEANUP: use Prolog terms in coroutining, avoid NULL pointers.
