Short: 060 Patches for UMult64/SMult64 V1.1 Author: kakace@aix.pacwan.net (Didier Levet), dbusse@metronet.de (Dirk Busse) Uploader: dbusse@metronet.de (Dirk Busse) Type: util/boot This is a small patch which replace the UMult64 and SMult64 functions of utility.library V39+. These new functions are 2 times faster than the ones placed by 68060.library, and 4 times faster than the Trap emulation. Well, these functions are not often used, so don't expect an incredible speedup :)) You can run SpeedTest (included) to see the benchmarks and to figure out if you really need to install these patches. I just write them to learn how to optimize 68060's code (sources included). So don't blame me if you think that the speed gain is useless ;-) Now, you only have to copy PatchMult64 in your "C:" directory, and add "C:PatchMult64" in your startup-sequence, right after Setpatch (or anywhere else, but not before). PatchMult64 sets the return code as follow : - 0 : Patches succesfully installed. - 5 : Patches already installed. - 10 : Unable to install the patches. That's all ! History: 1.0 Original Version from Didier Levet 1.1 - Source Code changed for using PhxAss (the best Assembler I know!) - Speed Improvement: UMult64 5.6% faster than V1.0 SMult64 3.6% faster than V1.0 - Fixed a bug: The Patch V1.0 is only installed if the 68060.library already loaded. But the patch is imperative if the 68060.library not installed. --------------------- Dirk Busse ============================= Archive contents ============================= Original Packed Ratio Date Time Name -------- ------- ----- --------- -------- ------------- 1645 816 50.3% 04-Sep-98 19:43:30 Mult64Patch.readme 488 413 15.3% 04-Sep-98 19:47:38 PatchMult64 3692 1168 68.3% 04-Sep-98 19:45:52 PatchMult64.s 1604 899 43.9% 24-Jul-97 16:19:50 SpeedTest 8206 1582 80.7% 04-Sep-98 19:19:12 UMult_SMult_060.s -------- ------- ----- --------- -------- 15635 4878 68.8% 05-Sep-98 21:45:40 5 files
