* mcount: tidy up ANSIficationEd Maste2018-10-201-2/+1
| | | | | | | | | | | | libc/gmon's mcount was ANSIfied in r124180, with libkern following over a decade later, in r325988, but some minor discrepancies remained. Update libc/gmon's mexitcount to an ANSI C function definition, and use (void) for libkern-only functions that take no arguments. Reported by: bde Notes: svn path=/head/; revision=339505
* General 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=326025
* 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.

* Changed to the C9x draft spelling of the (unsigned) integral typeBruce Evans1998-07-141-12/+12
| | | | | | | | | | | suitable for holding object pointers (ptrint_t -> uintptr_t). Added corresponding signed type (intptr_t). Changed/added corresponding non-C9x types for function pointers to match. Don't use nonstandard types to implement these types, and don't comment on them in <machine/types.h>. Notes: svn path=/head/; revision=37629
* Oops, fptrint_t still needs to be declared in <machine/profile.h> in theBruce Evans1998-07-101-9/+1
| | | | | | | | !KERNEL case. The kludge to get it declared in libc/gmon/mcount.c wasn't sufficient because fptrint_t is used in <sys/gmon.h>. Notes: svn path=/head/; revision=37542
* Added a kernel-only typedef (ptrint_t) giving an integral type that isBruce Evans1998-07-101-2/+11
| | | | | | | | | | | | | least unsuitable for holding an object pointer. This should have been used to fix warnings about casts between pointers and ints on alphas. Moved corresponding existing general typedef (fptrint_t) for function pointers from the i386 <machine/profile.h> to a kernel-only typedef in <machine/types.h>. Kludged libc/gmon/mcount.c so that it can still see this typedef. Notes: svn path=/head/; revision=37540

* 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
* Cleaned up interrupt masking by declaring the state variable in aBruce Evans1996-08-281-6/+5

* Implemented non-statistical kernel profiling. This is based onBruce Evans1995-12-291-8/+148
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | looking at a high resolution clock for each of the following events: function call, function return, interrupt entry, interrupt exit, and interesting branches. The differences between the times of these events are added at appropriate places in a ordinary histogram (as if very fast statistical profiling sampled the pc at those places) so that ordinary gprof can be used to analyze the times. gmon.h: Histogram counters need to be 4 bytes for microsecond resolutions. They will need to be larger for the 586 clock. The comments were vax-centric and wrong even on vaxes. Does anyone disagree? gprof4.c: The standard gprof should support counters of all integral sizes and the size of the counter should be in the gmon header. This hack will do until then. (Use gprof4 -u to examine the results of non-statistical profiling.) config/*: Non-statistical profiling is configured with `config -pp'. `config -p' still gives ordinary profiling. kgmon/*: Non-statistical profiling is enabled with `kgmon -B'. `kgmon -b' still enables ordinary profiling (and distables non-statistical profiling) if non-statistical profiling is configured.
