<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
|
|
|
|
|
no-source).
|
|
|
|
|
<LI> NEW: special meta-call handling for ISO mode. Reduce
|
|
|
|
|
amount of testing for other cases.
|
|
|
|
|
<LI> CLEANUP: complete cleanup of eval. No more duplicate code,
|
|
|
|
|
no more reg and fli.
|
|
|
|
|
<LI> SPEEDUP: move get_spy_creep to yap_flags. This speeds up
|

|
|
|
execute a bit.

|
<LI> NEW: strict_iso mode.
|
|
|
|
|

<LI> NEW: implement ISO exception handling for operations
|
|
|
|
|
between floating-point numbers in Linux.
|

|
<LI> NEW: handle floating point exceptions.
|

|
|
|
<LI> CLEANUP: get rid of EQUAL_FLOATS and EQUAL_LONG_INTS as

|
|
|
<LI> FIXED: define atanh and friends for VC++ environments.

|
|
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.
|
|
|
|
|
<LI> FIXED: do not mark or sweep environments twice. This fixes
|
|
|
|
|
Bart's YAP GC performance bug (as mentioned in comp.lang.prolog!).
|
|
|
|
|
<LI> NEW: do variable shunting, not that it helps very much.
|
|
|
|
|
<LI> FIXED: save should only save as many registers as it
|
|
|
|
|
needs, and the ones it does should be adjusted when restoring.
|
|
|
|
|
<LI> NEW: stream_select/3.
|
|
|
|
|
<LI> NEW: save/2.
|
|
|
|
|
<LI> NEW: char_conversion/2 and current_char_conversion. Add
|
|
|
|
|
ISOGetc for this, change scanner for having two getcs (one
|
|
|
|
|
within strings, the other elsewhere).
|
|
|
|
|
<LI> FIXED: was recording source for optimised clauses, not
|
|
|
|
|
just source for module preprocessed clause.

|
|
|
|
|
<LI> CLEANUP: replaced PlPutc() by specialised versions for
|

<LI> CLEANUP: got rid of PlPutChar();
|
|
|
|
|
<LI> FIXED: ISO compatible mode for floor and friends.
|

|
|
scanner.

|
|
|
|
<LI> FIXED: stream_property should not work with aliases.

|
|

|
|
|
|
|
<LI> FIXED: avoid using atom_chars within the system.
|
|
|
|
|
<LI> FIXED: number_chars(X,I) and number_codes/2 with bad I
|
|
|
|
|
should give error in ISO mode.
|
|
|
|
|
<LI> FIXED: make ISO abolish/1 succeed for undefined procedures.
|
|
|
|
|
<LI> FIXED: number_chars and atom_chars should be ISO
|
|
|
|
|
compatible in ISO mode.
|
|
|
|
|
<LI> FIXED: errors in call should throw ISO errors.
|
|
|
|
|
<LI> FIXED: functor/3 should now have standard ISO behaviour on
|
|
|
|
|
errors.
|
|
|
|
|
<LI> FIXED: assert(X) would loop.
|
|
|
|
|
<LI> FIXED: char_conversion/2 is now also a directive.
|
|
|
|
|
<LI> FIXED: ensure_loaded/1 should be directive and not a built-in.
|
|
|
|
|
<LI> FIXED: current_predicate/1 should not show system
|
|
|
|
|
predicates and should be module aware.
|
|
|
|
|
<LI> FIXED: utilpred.s now compiles with -DEUROTRA.
|
|
|
|
|
<LI> FIXED: abolish/1 had several nasty bugs, especially in ISO mode.
|
|
|
|
|
<LI> CLEANUP: got rid of nasty config.cache in main directory.

full meta-call, and a system catch, that uses $execute0 and

yamop and GONEXT. The same code does both indices and clauses.

growheap and growlocal) have now been merged in a general

<LI> InitStaff() now has an argument saying whether we are

<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
|
|
|

|
|
|
|
|
<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

confusing the parser.

<LI> CLEANUP: use derefa when we know the possible address for

a variable. This avoids reading a memory cell twice.

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> FIXED: YAP now makes procedures dynamic after first assert.
|
|
|
|
|
<LI> FIXED: because of disjunctions, variables in clauses do not
|
|
|
|
|
always grow linearly. Change compiler to informe gc of actual
|
|

|
|
live variables in an environment at any point, not including
|
|

|
|
variables outside the current branch (even if at ancestor's

<LI> NEW: speedup compact_heap.

<LI> NEW: in GC check if db terms are in use, and if not reset

be a single character. Some MS-DOS systems accept both slash
|
|
|
|
|

|
|

<LI> FIXED: for compatibility with other Prologs, YAP now
|
|
|

changes directory to the directory

<LI> FIXED: bug in read_term/singletons. I incorrectly assumed

|
|
|
|
|
<LI> FIXED: too much space was being allocated for 64 bit
|
|
|
|
|

|
|
|
|

<LI> FIXED: error handling in data base could collapse.
|
|
|
|
|
<LI> FIXED: ASP for growheap could be wrong.
|
|
|
|
|
<LI> FIXED: growheap and growstack forgot about dangling

<LI> FIXED: increase margins as garbage collections happens.
|
|
|
|

<LI> FIXED: make recorded and friends restartable for the
|
|
|
|
|
case there is no space left to copy the new term.
|
|
|
|
|
<LI> FIXED: make memory allocation routine more generic, try
|
|
|
|
|
to use temporary files when /dev/zero is not available,
|
|
|
|
|
control whether we are fetching the right addresses, and
|
|

close open mmaped stream.

<LI> FIXED: make sure we always have an error handler in the

array extensions. Access to named dynamic arrays now goes
|
|

|
|
through the trail.
|
|
|

<LI> FIXED: make arg/3 silently fail on negative or 0 first
|

with other Prologs.

|
|
<LI> CLEANUP: improve meta-call performance by avoiding
|
|
|
|
|
unnecessary choice-points.
|
|
|
|
|
<LI> FIXED: assert and source mode are now aware that modules
|
|
|
|
|
call meta-calls.
|
|
|
|
|
<LI> FIXED: libraries should be checked for existence before
|
|
|
|
|
checking for the files themselves.
|
|
|
|
|
<LI> NEW: dynamic loader now works in Linux/Alpha and in
|
|
|
|
|
Digital Unix/Alpha! Fixed bugs where YAP would corrupt global
|
|
|
|
|
variables allocated by external functions.
|
|
|
|
|
<LI> FIXED: BP_FREE didn't do callee save for PREG, possibly
|
|
|
|
|
corrupting the caller. Core dumped print/1 on X86.
|
|
|
|

<LI> CLEANUP: separate error handling into separate files.

<LI> NEW: execute_goal(Goal) function allows calling

Prolog from C. Still under testing, and not yet officially in

|
|
|
the interface. Note that execute_goal will destroy all X

performs an implicit cut).

<LI> FIXED: DEPTH_BOUND_CALL was not restoring depth for retry_c.
|

start_low_level_trace and stop_level_trace, or T from

<LI> ISO-YAP: add Z is float_fractional_part(X).
|
|
|
|
|
<LI> ISO-YAP: arg/3 now generates errors.
|
|
|
|
|
<LI> ISO-YAP: abolish/1 now does errors the YAP way, and

only abolishes dynamic procedures. Use abolish/2 to clear

static procedures.
|

<LI> Abort now jumps to before the absmi emulator and then
|
