* sys: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326023

* Renumber copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* Backed out the micro-optimization in 1.4. It was to help gcc-2.6.3Bruce Evans2003-07-251-6/+1
| | | | | | | | | | | | on i486's (and probably i386's), but it has had very little effect since gcc-2.7 or gcc-2.95. With gcc-3.3, it gave a small pessimization for at least i386's, athlon-xp's and pentium4's, a small optimization (I think) for pentium1's, and made no difference for i386's. (movzbl is best for all the later processors, and the micro-optimization was to stop it being used on i486's.) Notes: svn path=/head/; revision=118017

* Make the long-awaited change from $Id$ to $FreeBSD$Jordan K. Hubbard1997-01-141-1/+1
| | | | | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise. Notes: svn path=/head/; revision=21673

* Rearrange the inner loop of scanc() to get better code on i*86'sBruce Evans1995-07-111-2/+10
| | | | | | | | | | | | | | (on an i486, 10 cycles (+ cache misses) instead of 15). The change should be a no-op if the compiler is any good. The best possible i*86 code for the same algorithm is only 1 more cycle faster on i486's so I don't want to bother implementing an assembler version. scanc() is a bottleneck for OPOST processing. It is naturally about 4 times as slow as bcopy() on 32-bit systems. Notes: svn path=/head/; revision=9485
* <libkern/libkern.h> has moved to <sys/libkern.h> (repository copy).Poul-Henning Kamp1995-03-171-2/+2
