| | | | | | | | | compiled with pie or profiling enabled. This was missed when the independent depend target was removed. Align this target with the inference rules in bsd.lib.mk. This now creates mcount.d as it should and fixes 'make clean' which previously left mcount.po.d behind. ok guenther

| | | | | | value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

* for some time now mandoc has not required MLINKS to functionjmc2016-03-301-3/+1
| | | | | | | | | | | | correctly - logically complete that now by removing MLINKS from base; authors need only to ensure there is an entry in NAME for any function/ util being added. MLINKS will still work, and remain for perl to ease upgrades; ok nicm (curses) bcook (ssl) ok schwarze, who provided a lot of feedback and assistance ok tb natano jung

| | | | | | | | | | | kgmon(8) to deal with them, this time without public header changes. Previously various CPUs were iterating over the same global buffer at the same time to modify it and never ended.

* - remove all trailing whitespaceaaron1999-07-091-3/+3
| | | | | | | | | | * except when it is escaped with a `\' at the end of the line - fix remaining .Nm usage as well - this is from a patch I received from kwesterback@home.com, who has been working on some scripts for fixing formatting errors in mdoc'd man pages Ok, so there could be a cost/benefit debate with this commit, but since I have the patch we might as well commit it...

* Add thread-safety to libc, so that libc_r will build (on i386 at least).d1998-11-201-2/+2
| | | | | | | | | | | | | All POSIX libc api now there (to P1003.1c/D10) (more md stuff is needed for other libc/arch/*) (setlogin is no longer a special syscall) Add -pthread option to gcc (that makes it use -lc_r and -D_POSIX_THREADS). Doc some re-entrant routines Add libc_r to intro(3) dig() uses some libc srcs and an extra -I was needed there. Add more md stuff to libc_r. Update includes for the pthreads api Update libc_r TODO

* use p->hashfraction when doing non-time-critical calculations, rather thanderaadt1996-06-182-11/+18
| | | | | | | | | | | using HASHFRACTION directly. in time-critical calculations, if HASHFRACTION is a power of two, check that p->hashfraction == HASHFRACTION and if so do the calculation with the compiled-in value so that the compiler can optimize out (potentially) expensive divisions. if p->hashfraction != HASHFRACTION, actually do the division. This has the result that on machines with slow division, the division can be optimized out of the common case, but that if HASHFRACTION changes from the compiled-in value (for whatever reason), profiling will still work. Changes suggested by Chris Torek.
