Short: IXemul 44.0 - 68020+fpu library
Author: various
Uploader: fnf@ninemoons.com
Type: dev/gcc
This is ixemul.library release 44.0, a shared library that makes it possible
to compile and run most Unix programs under AmigaOS with almost no changes.
IXemul is part of the ADE (Amiga Developer's Environment), a community
effort to produce a complete development environment that is stable,
available in source, and completely self-hosting. See the ADE readme file
at ftp://ftp.ninemoons.com/pub/ade/README for more details about ADE.
As of version 43.1, IXemul includes Jeff Shepherd's networking code. If
ixnet.library (included) is installed then ixemul.library will use the
networking functions from the ixnet.library, instead of the default dummy
implementation. Ixnet.library works with AS225 and with AmiTCP. It
supports both clients and daemons. A program that uses networking functions
is completely shielded from the AS225 and AmiTCP differences by
ixnet.library, which will take care of all the details for you. That means
that there is no longer any need to provide two different binaries, one for
AS225 and one for AmiTCP. Furthermore, it is relatively easy to add support
for other network packages.
The following are the changes made since the 43.1 release:
Kriton Kyrimis updated ixprefs.
David Zaroski updated ixtrace.
Fixed link count for directories. Thanks to Norbert Pueschel.
umask implemented for for open() and mkdir(). Thanks to Norbert
Pueschel.
Added muFIBB_SET_GID, which will be implemented in the next
version of MultiUser. The old way of handling setgid was
confusing and even potentially dangerous. Thanks to Norbert
Pueschel.
Added the translation unix sticky bit -> AmigaDOS h bit. This one
is more for aestaethical reasons, as the h bit is no longer
supported in 3.x. Thanks to Norbert Pueschel.
Added a field 'void *u_user;' near the beginning of the user
struct which everybody is free to (ab)use. It can be handy to
store task private data in the user struct, at least, I had to
use it recently.
Added an ix_amiga.h header, which will contain all amiga specific
functions and macros in ixemul.library and libc.a, together with
a description.
Profiling has been enhanced. Ixprefs adds a new profiling
preference: either take samples only while your program is
running and the PC is within your program, or take samples while
your program is running and if the PC is outside your program
code (e.g. in ixemul or in intuition.library), use the last
function your program entered before calling ixemul or whatever,
or always take samples, even if other programs are running.
Again, the last recorded function gets the hit in those cases.
An array of 100 longs to store the A4 register of shared
libraries has been added to the user struct. This array can be
easily increased in future releases, should the need arise. The
first 20 slots are for your own free use, the other slots should
be registered. See the file REGISTRY in the ixemul source
distribution for more details.
Fixed yet another path bug. Running a shell script that's placed
somewhere in your PATH from 'make' failed, unless the filename of
the script was absolute.
Added vfork_setup_child to libc.a. This is a wrapper intended to
make life just a little bit easier for those who need to use the
vfork2()/vfork_resume() trick. It replaces the old
'ix_resident()/ix_get_vars2()' pair.
Fixed more problems with the routines that start a shell
script. This time problems with symbolic links have been fixed.
Fixed problems when parsing a pathname of a shell script,
preventing the execution of that script.
Replaced the stdio-sources by the NetBSD 44.0 versions, which
incidentally fixed the broken fgetpos function. This change also
adds printf() and scanf() support for the 'long long' datatype.
Added support for the O_CASE open() flag: this will open an
existing file only if the filenames match using a case-sensitive
comparison.
fstat() didn't compensate the file time for the current timezone
offset.
Ixemul now supports the 68010 CPU. Thanks to Pascal Eeftinck for
pointing out that the 68010 uses a 68020-like stackframe.
Build the version.[ch] files in the build directory instead of in
the source directory.
Fixed fchdir().
Changed the machine name as returned by uname() to "m68k". Thanks
to Lars Hecking for this.
O_ASYNC I/O is now partially supported: select() will test for
this situation.
/dev/tty is now translated to console:.
Implemented pseudo-terminals support using the FIFO device.
Many, mostly small, changes to become more NetBSD
compatible. Where possible, I've replaced the old sources with
the NetBSD 1.1 sources.
The select() function has been improved: it is now much faster
and works much better.
Using F_SETFL with fcntl() failed if the file wasn't a regular
file. It now also works for pipes and sockets.
Requesters that are from ixemul.library or ixnet.library now have
the name of the library as their title, so that you can see that
they are from the library, and not from the application. Thanks
to Udo Schnurpfeil for suggesting this.
The tty database functions unfortunately slipped through and
weren't included with 43.1. They are back in 44.0.
Implemented mmap() and friends. Of course, any mmap feature that
actually requires a MMU will return an error. But if mmap() is
used to load a file into memory, then it works fine.
Applied patch from Kamil Iskra to improve ixemul stack extension
handling.
The net ixemul library distribution consists of several archives:
ixemul-bin.lha Utils for gnu/bin, like ixtrace and ixconfig
ixemul-sdk.lha Files needed to build applications that use
ixemul.library.
ixemul-doc.lha Various documentation, such as this file
ixemul-src.lha Complete source code for ixemul library
ixemul-tz.lha Pieces for doing TZ (timezone) management
ixemul-CCCF.lha Specific flavors of the library, where 'CCC'
is one of 000, 020, 030, or 040, for 68000, 68020,
68030, and 68040 respectively, and 'F' is either
'f', 's', or 't' for FPU support or soft floating
point or a "trace" version (also soft float)
respectively.
For further information consult the NEWS, INSTALL, README and TODO files in
the documentation archive.
