VERSION 4.0.4
=============
* FIXED: Problem in GUI tracer tracing predicates loaded from ?- [user].
* MODIFIED: The file-reading predicates (consult, use_module, load_files,
etc.) no longer change current input to the file loaded. This implies
that read/1 and friends read from the current input before the load
predicate was started rather then the file we are loading from.
* FIXED: Setting break-points on facts, or in general on the last
(I_EXIT or I_EXITFACT) instruction of a clause.
VERSION 4.0.3
=============
* ADDED: New hooking system for help/0, help/1 and apropos/1.
* FIXED: Allow for -f "c:\..." in Windows.
* ENHANCED: Moved boot/listing.pl to the library, reducing the
footprint and startup time. Also modernised the code a bit,
allow for hooks, so listing(class->method) lists an XPCE method
and allow for partial listing: listing(foo(a, _)) to get only
the clauses for which a unifies to the first argument.
* FIXED: tracer not to trap cut-port in system predicates (GUI).
* FIXED: Atom-GC problem: global options structured used pointers
to string of unlocked atoms.
* ENHANCED: the GUI debugger. Too much to name it here.
* INTERNAL: Moved message-activation of spy and nospy predicates to
foreign-code to make sure it gets always called.
* FIXED: Bug in recorded database, reported by Michael Heerdegen.
* FIXED: Removed trace of rl_add_history()
* FIXED: Handling of :- dynamic Module:Name/Arity in PceEmacs
cross-referencer.
* FIXED: Cleanup of code for setting break-points. Make this code
work again from PceEmacs.
* ENHANCED: prolog_to_os_filename(-Pl, +Os) to convert 8+3 filenames
to long filenames.
* ENHANCED: Allow setting spy-point from PceEmacs.
* CLEANUP: Replace some more warnings with exceptions.
* ENHANCED: library(url) for breaking down and constructing URL strings
with some new functionality. Additions by Lukas Faulstich. Also
fixed a dangling choice-point in decoding a www-encoded string.
* ENHANCED: Moved tty_size/2 from library(tty) to built-in, exploiting IOCTL
calls to fetch the terminal size when available. This make tty_size/2
return the actual values rather than constant values from the moment of
startup. Reported by Robert van Engelen.
VERSION 4.0.2
=============
* FIXED: Memory leak in PL_get_chars() using CVT_WRITE. Reported by
Marcin Golebski.
* INSTALL: export CIFLAGS=/path/to/local/include should now be
honoured correctly by configure (Lukas Faulstich)
* FIXED: absolute_file_name/3 not to trust its cache.
* ADDED: callable/1 for better compatibility.
* FIXED: $qlf_info/4 to request information on QLF files. Also turned
a couple of common warnings into proper exceptions.
* FIXED: Avoid the usage of the appearently badly supported Win32 function
GetFileInformationByHandle(), now using GetFileSize(). This fixes some
false-alarm about not being able to find the system resources.
* REMOVED: ed/1, also from the backward compatibility module. Edit/1
is the generic editing front-end.
* FIXED: writeq(a(b,c,(d,e))), reported by Joachim Katzer.
* FIXED: Memory leak in expand_file_name/2. Reported by Daniel Cote.
* FIXED: Print error-locations in files holding the ~-character.
Thanks to Mike Maxwell.
VERSION 4.0.1
=============
* PACKAGE: Many installation patches, added libraries, notably to
the XPCE subsystem.
* ADDED: Skeleton dotfiles for both Prolog and XPCE to the dotfiles
directory.
* FIXED: plrc utility for modifying archives. Thanks to Lourens
van der Meij.
* FIXED: ANSI-C incompatibility, breaking compilation using AIX cc
(Sterling Smith).
* FIXED: end_of_file issues in readln/[1,2,5] (library(readln)) and
modernised the code a bit.
* FIXED: Write out-of-range floating point numbers properly (Bart Demoen).
increase in version number. From the XCircuit homepage:
Note that the March 28, 2001 version corrects a bug due to
dubious C syntax causing segmentation violations when xcircuit
was compiled without the debug option.
C Trivia question:
What does "x[a] = x[--a]" do?
Answer A: "x[a] = x[a - 1]; a--"
Answer B: "a--; x[a] = x[a]"
Answer C: either A or B, depending on your OS, compiler version,
and/or debug or optimizer switch.

Changes since the last packaged snapshot from the authors announcements:
Icarus Verilog snapshot 20010422
--------------------------------
I've integrated a bunch of UDP patches from Stephan Boettcher. These
go to the core of ivl, so if you use Icarus Verilog with UDPs, you
might want to give this a test for us.
Stephan has also added some ivl_target support for UDP devices. This is a
prerequisite to vvp support for UDP devices.
Some of you have been beating me over the head about disable, so the
vvp target now supports disable. It only works in certain very constrained
situations, but the idea is there and the more common cases are simply a
matter of getting around to them. I actually could use more examples of
the use of disable for the test suite.
In the process, I have settled on the interaction of threads and scopes,
and changed the %fork syntax to match. See the README.txt and opcodes.txt
file for details. The implementation of %end and %join simplified in
the process.
The vvp-tgt code generator supports a few more gate types. New gate
types are pretty easy to add, it's just boring grunt work. That's why
they've been popping up slowly.
I've also got certain behavioral shifts working. Only constant shifts,
so far, but this covers a pretty large percentage of the real world
uses of shift, I think.
I fixed a few specify block parse problems, so it should ignore
even more complex specify blocks now:-) One of these days I really will
properly support specify blocks.
PROGRESS
I was hoping to get vvp up to a similar level as vvm by the end of
April, but that doesn't look like it's going to happen. I'm up to 182
tests passed, compared to 318 of Icarus Verilog/vvm, so I have a ways
to go yet. I see no real point to making a release until I get up to
300 or so tests passed. That is the goal for 0.5 release.
But of course if vvp is enough for you, then it is soooo much faster
then vvm.
Icarus Verilog 20010415 Snapshot
--------------------------------
As with all the most recent snapshots, this is almost entirely progress
with the vvp code generator and simulation engine. I'm up to 159 tests
passed in the test suite, so I'm getting there. But there's still plenty
to go.
I also fixed what appeared to be a minor problem with elaboration of ?:
expressions in continuous assignments. The code was actually fine, it
was a spurious assert. This fix affects vvm as well.
Icarus Verilog/vvp now support <= statemements with internal delays.
That is, "foo <= #10 bar;" should work properly, and there are tests
in the suite that prove it. This is a pretty common syntax, so this
should help a lot of folks.
I also fixed a bug in the code generator that would cause it to put a
constant bit as a destination for the bitwise boolean operators. This
caused run-time asserts.
The event or support in vvp has been extended to now support arbitrary
width, so now you can for example wit for any changes in a 32bit reg.
This handles most of the likely cases, so @ statements should now be
pretty generally functional.
The handling of run-time threads has been revamped in preparation for
support of the disable statement. It also plugs a memory leak where
fork/join and task/function calls are invoked. And this version should
also clean up all those tiny initial foo=bar threads that all programs
seem to have. Threads that are done are now freed, along with their
memory, hopefully reducing the runtime memory footprint.
That's pretty much it this time 'round. Working with threads took some
time, so the progress isn't as flashy as it sometimes is.
There is still lots to do with vvp before 0.5, but I would appreciate
any feedback you can offer. It's complete enough already that I'm able
to accept bug reports on it, even if it turns out to be a "not supported
yet" type of thing. At this point, I'd be curious to know what hangups
are preventing its regular use.
What is this?

pnm2ppa, a PPM to PPA converter, creates output using the PPA (printer
performance architecture) protocol. This protocol is used by some HP
"Windows-only" printers, including the HP Deskjet 720C series, the HP
DeskJet 820 series, and the HP DeskJet 1000 series. It has been
tested on all three series, but your personal experience (positive or
negative) is very much appreciated!
Surface Impedance Method for Interconnect Analysis.
SIMIAN is a two dimensional frequency dependent series
impedance extraction tool for inerconnects and transmission
lines using conductors of rectangular or circular cross section.
The use of the surface ribbon method (SRM) greatly enhances
the speed of computation relative to the volume filament
method (VFM).
