Short: MuLib aware 68060, 68040, 68030 and 68030.libraries Author: thor@math.tu-berlin.de (Thomas Richter) Uploader: thor math tu-berlin de (Thomas Richter) Type: util/sys Version: 40.16,40.18 Requires: Os 2.04, an 68060, 040, 030 or 68020. Architecture: m68k-amigaos ----------------------------------------------------------------------------- This archive replaces the 68040Lib archive of former releases. It contains all processor libraries for the complete motorola CISC family, from the 68020 up to the 68060. ----------------------------------------------------------------------------- These are processor libraries that make 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 FPSP motorola FPU emulation core for both the 68040.library resp. 68060.library, and has been carefully hand-optimized. It does not include questionable patches, but is still configurable thru the mmu.library "MMU-Configuration" file. All libraries within this archive are VMM aware and will emulate non-implemented instructions even if placed in virtual memory. 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. The libraries provide LVOs to control the FPU exception processing, and a shell tool, named "FPU", to configure it. Moreover, the 68040.library and 68060.library add a new resource to your system, the "fpsp.resource". This resource provides the emulation routines for unimplemented instructions of the 68040 and the 68060. It is installed by the libraries on startup and made use of as soon as the 68040/060 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 libs would have to handle otherwise. The math libraries included in Os 3.9 will detect and use this resource themselves, so FastIEEE is not required for the latest Os release. Note that a higher version number does not always mean better code... ------------------------------------------------------------------------------ This library is part of the MMULib distribution.

However, the following methods of distribution involving payment shall not in and of themselves be a violation of this restriction: (i) Posting the Program on a public access information storage and 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.
