Short: A MuLib aware 68040.library, 68030.library, 68020.library
Uploader: thor@math.tu-berlin.de (Thomas Richter)
Author: thor@math.tu-berlin.de (Thomas Richter)
Type: util/sys
Requires: Os 2.04, an 68040
Version: 40.8
-----------------------------------------------------------------------------
This is a 68040.library which makes use of the MMU.library to setup its MMU
tree. Hence, the setup logic of this library has been streamlined as the
complete MMU setup logic has been removed. Since it does not build an MMU
tree itself, it will save approximately 200K of memory for an initial MMU
tree which would be wasted otherwise. Moreover, this library makes use of the
latest (1.2) FPSP motorola FPU emulation core and has been carefully
hand-optimized. It does not include questionable patches, but is still
configurable thru the mmu.library "MMU-Configuration" file.
Futhermore, this archive contains the CPU driver libraries for the 68020
and the 68030, to be able to make use of the "FPU" command.
Special care must be taken to use this library on P5 hardware which is,
unfortunately, not always auto-configuring. A setup script is included in
the archive.
This library *IS NOT* a must if you want to use the mmu.library. It is an
option which was written to reduce memory usage.
A new 680x0.library and a patch for SetPatch is included to get rid of
the 68040 dummy libraries which are still in use. A beta version of an
analogue 68060.library is available.
This 68040.library provides an LVOs to control the FPU exception processing,
and a shell tool, named "FPU", to configure it.
Moreover, this 68040.library adds a new resource to your system, the
"fpsp.resource". This resource provides the emulation routines for un-
implemented instructions of the 68040. It is installed by the 68040.library
on startup and made use of as soon as the 68040 detects an FPU instruction
it can't handle itself. It is also used by an external tool, FastIEEE, which
redirects the mathieeee...library vectors to this resource which hence
avoids an unecessery emulation exception the 68040.library would have to
handle.
Note that a higher version number does not always mean better code...

This License applies to the computer programs known as the "mmu.library",
the "680x0.library" and the "68040.library V40" The "Program", below, refers
to such program. The "Archive" refers to the package of distribution, as
prepared by the author of the Program, Thomas Richter. Each licensee is
addressed as "you".

payment for some product or service that includes a copy of the Program
"without charge"; these are only examples, and not an exhaustive enumeration
of prohibited activities).
However, the following methods of distribution
involving payment shall not in and of themselves be a violation of this

retrieval service for which a fee is received for retrieving information
(such as an on-line service), provided that the fee is not
content-dependent (i.e., the fee would be the same for retrieving the same
volume of information consisting of random data).
(ii) Distributing the Program on a CD-ROM, provided that
a) the Archive is reproduced entirely and verbatim on such CD-ROM, including
especially this licence agreement;
b) the CD-ROM is made available to the public for a nominal fee only,
c) a copy of the CD is made available to the author for free except for
shipment costs, and
d) provided further that all information on such CD-ROM is redistributable
for non-commercial purposes without charge.
Redistribution of a modified version of the Archive, the Program or the
