Shared libraries for NetBSD 1.4 (and earlier) compatibility
this has only been done for i386 & sparc so far, and deals with using
/emul/aout for these systems that are ELF now.
XXX: port to alpha, m68k, mips*, arm32 and ns32k (anything else?)
User-visible changes in 0.8.15:
- A few changes in the core of the custom chip emulation; this should mean
more accuracy in general, but likely also a few new bugs in this version.
It may be a little slower as well.
- "68040" emulation. Dedicated to all the clueless folks out there.
(with thanks to Christian Bauer)
Convert most MESSAGE files to new syntax (${VARIABLE} gets replaced,
not @VARIABLE@, nor @@VARIABLE@@).
By default, substitutions are done for LOCALBASE, PKGNAME, PREFIX,
X11BASE, X11PREFIX; additional patterns can be added via MESSAGE_SUBST.
Clean up some packages while I'm there; add RCS tags to most MESSAGEs.
Remove some uninteresting MESSAGEs.

Integrated updates to write-cache from Tom Vijlbrief.
Reorganized docs/ a little. Split the xml docs into 2 docbooks.
There is now a PUG (Plex86 User's Guide) and a
PIG (Plex86 Internals Guide). I removed the tarball out of
the CVS tree, and will upload pre-generated docs to the FTP
server periodically. Look for docs-yyyy_hhmm.tar.gz.
The tarball now contains both HTML and PS formats.
There's also some notes on what packages are needed to generate
and develop your own docs. (docs/xml/README) This release should
make it easier for people to help out.

Added another docs chapter (17) to the user's manual, relating to
dynamic translation (DT) ideas for maintaining linear to translated
code address mappings and some other stuff. You can update from
CVS and just untar the docs/ tarball if you want.

Integrated write-cache plugin from Tom Vijlbrief, and his related
mods to the hard drive code, to handle > 32-bit file IO.
Integrated small FreeBSD Makefile mods from Alexander Langer.
Regenerated configure.

Integrated FreeBSD host port by Alexander Langer <alex@big.endian.de>
Note: this port does not work yet, but was uploaded so others
can work on it.

Integrated LBA patches from Tom Vijlbrief, to rombios.c and harddrv.cc.
I modified the patches slightly, and have not tested them much.
Am uploading changes to let Tom test them as integrated.
Tom was able to access up to 2GB partitions with his changes.
Generated new BIOS. Changed all conf files to use new BIOS.

Added dt-testbed dir. This is just a small separate testbed program
for developing thoughts about generated code for a quasi-dynamic
translation scheme. If you're interested in such developments,
look at the README file in that dir.

Added framework for write-cache buffering (for "persistent disks").
Created new plugin, in directory user/plugins/write-cache/. It
does nothing currently, other than pass disk accesses to libc.
This is to make it easier for others to implement the actual logic,
without having to know much about plex86 internals. There are some
notes in the plugin C code.
I also created a new button (really lame) on the GUI. This triggers
a call to the plugin, so the user can select when to flush (commit)
the writes in the write-cache to disk and clear the cache.
Eventually, a nice menu system might do this with a "Are you sure?"
dialog or something similar.
It is possible that a large number of disk writes may exceed the
size of the write-cache (which should be configured by an option
to the plugin eventually). In that case, it would be good to present
the user with 2 options: 1) Quit altogether and ignore writes,
and 2) commit writes and continue. This should eventually be
GUI oriented, by stdin would be OK for now.
out of date - it was based on a.out OBJECT_FMT, and added entries in the
generated PLISTs to reflect the symlinks that ELF packages uses. It also
tried to be clever, and removed and recreated any symbolic links that were
created, which has resulted in some fun, especially with packages which
use dlopen(3) to load modules. Some recent changes to our ld.so to bring
it more into line with other Operating Systems also exposed some cracks.
+ Modify bsd.pkg.mk and its shared object handling, so that PLISTs now contain
the ELF symlinks.
+ Don't mess about with file system entries when handling shared objects in
bsd.pkg.mk, since it's likely that libtool and the BSD *.mk processing will
have got it right, and have a much better idea than we do.
+ Modify PLISTs to contain "ELF symlinks"
+ On a.out platforms, delete any "ELF symlinks" from the generated PLISTs
+ On ELF platforms, no extra processing needs to be done in bsd.pkg.mk
+ Modify print-PLIST target in bsd.pkg.mk to add dummy symlink entries on
a.out platforms
+ Update the documentation in Packages.txt
With many thanks to Thomas Klausner for keeping me honest with this.

Integrated mods from Warwick Duncan for some remaining C++ -> C
comment conversions in plugin directories.
Added dynamic translation idea chapter to docs.
