* Do not use <machine/float.h>, that is an deformed BSD-ism.deraadt2012-06-251-2/+2
| | | | | It turns out <float.h> is the right file to pull in. ok millert
* __tfork() needs to set the stack address of the new thread in the kernel,guenther2012-06-211-6/+2
| | | | | | | | | so that it can't get a signal while still running on the parent thread's stack. Also, pass in sizeof(struct __tfork) to provide forward compat when more members are added. This is an ABI change, so switch syscall numbers and bump lib majors this time. ok deraadt@ matthew@
* alloca.c cannot be usedderaadt2012-04-121-2/+0

* remove rfork(); ok guenther miodderaadt2012-04-121-32/+0

* Move __tfork_thread() from rthreads (libpthread) to libc so thatguenther2012-03-221-0/+53
| | | | | | it can be used for not-strictly-threading purposes ok matthew@ kurt@
* sigstack() is long dead, and the compat sigaltstack syscall is gone too.guenther2011-11-221-2/+2
| | | | | | Correct the namespace protections for sigreturn(), sigwait(), and psignal() ok millert@
* Revert (leaving the complex math part alone). Some stuff is dependingmartynas2011-07-082-1/+40
| | | | | on this historical behavior; so we're stuck in this stupid situation. No cookie for me.
* Move fabs(3), frexp(3), and modf(3) to libm--nothing has been usingmartynas2011-07-082-40/+1
| | | | them in libc for a very long time. OK guenther@.
* On PowerPC we cannot manipulate FPSCR[VX]--it's a summary of allmartynas2011-05-251-2/+6
| | | | | | | | the invalid exception bits, as described in Section 3.3.6.1.1 of PowerPC Architecture Programming Environments Manual. A proper way to cause an invalid operation exception is to set FPSCR[VXSOFT]. Similarly, we clear all the FPSCR[VX*] bits otherwise.
* Move __cerror to ___cerror with a weak alias so that rthreads can override it.guenther2011-04-041-2/+4
| | | | | | On mips64, also correct the name called from plain cerror to __cerror. "looks correct" miod@
* Provide a WEAK_ALIAS macro in <machine/asm.h> for the few platformsguenther2010-10-011-2/+2
| | | | | | | that didn't already have one, and then immediately use it in libc's SYS.h ok miod@
* junk spacederaadt2009-04-291-1/+1

* remove from gen so that lint doesn't check gen if assembly versionsmartynas2009-04-211-1/+1
| | | | are available. spotted by theo
* - ldexp implementation has issues. switch to the one from libmmartynas2009-04-193-450/+2
| | | | | | - remove frexp in hppa64, cloned from hppa - move generic ieee754 implementations of modf and ldexp to gen ok kettenis@, "looks good" millert@
* use sys/cdefs.h; pointed out by theomartynas2008-12-102-4/+4

* - replace dtoa w/ David's gdtoa, version 2008-03-15martynas2008-09-073-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - provide proper dtoa locks - use the real strtof implementation - add strtold, __hdtoa, __hldtoa - add %a/%A support - don't lose precision in printf, don't round to double anymore - implement extended-precision versions of libc functions: fpclassify, isnan, isinf, signbit, isnormal, isfinite, now that the ieee.h is fixed - separate vax versions of strtof, and __hdtoa - add complex math support. added functions: cacos, casin, catan, ccos, csin, ctan, cacosh, casinh, catanh, ccosh, csinh, ctanh, cexp, clog, cabs, cpow, csqrt, carg, cimag, conj, cproj, creal, cacosf, casinf, catanf, ccosf, csinf, ctanf, cacoshf, casinhf, catanhf, ccoshf, csinhf, ctanhf, cexpf, clogf, cabsf, cpowf, csqrtf, cargf, cimagf, conjf, cprojf, crealf - add fdim, fmax, fmin - add log2. (adapted implementation e_log.c. could be more acruate & faster, but it's good enough for now) - remove wrappers & cruft in libm, supposed to work-around mistakes in SVID, etc.; use ieee versions. fixes issues in python 2.6 for djm@ - make _digittoint static - proper definitions for i386, and amd64 in ieee.h - sh, powerpc don't really have extended-precision - add missing definitions for mips64 (quad), m{6,8}k (96-bit) float.h for LDBL_* - merge lead to frac for m{6,8}k, for gdtoa to work properly - add FRAC*BITS & EXT_TO_ARRAY32 definitions in ieee.h, for hdtoa&ldtoa to use - add EXT_IMPLICIT_NBIT definition, which indicates implicit normalization bit - add regression tests for libc: fpclassify and printf - arith.h & gd_qnan.h definitions - update ieee.h: hppa doesn't have quad-precision, hppa64 does - add missing prototypes to gdtoaimp - on 64-bit platforms make sure gdtoa doesn't use a long when it really wants an int - etc., what i may have forgotten... - bump libm major, due to removed&changed symbols - no libc bump, since this is riding on djm's libc major crank from a day ago discussed with / requested by / testing theo, sthen@, djm@, jsg@, merdely@, jsing@, tedu@, brad@, jakemsr@, and others. looks good to millert@ parts of the diff ok kettenis@ this commit does not include: - man page changes
* - move isinf, isnan dups to gen, since most is ieee 754martynas2008-07-244-95/+10
| | | | | | | | | | | | | | | | - is{inf,nan} should be macros for real-floating, so rename to __is{inf,nan}, per C99 - implement C99 __fpclassify(), __fpclassifyf(), __isfinite(), __isfinitef(), __isnormal(), __isnormalf(), __signbit(), __signbitf() - long functions added, but not yet enabled, till ieee.h is fixed - implement vax equivalents of the functions - reimplement isinff, isnanf in a better way, and move to libc - add qnan bytes for all archs - bump major man pages will follow ok millert@. arm bits looked over by drahn@ discussed w/ theo, who showed the right direction, to put these functions in libc
* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-266-48/+6
| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@
* Gently cast to make lint happy.drahn2006-03-311-2/+2

* Be kind to lint, and specify the correct width on these constants.drahn2006-03-313-6/+6
|
* if we pull in a .S file, we must fake out the lint with a .c filederaadt2005-11-291-0/+1
| | | | | for this first cut, we will do this for alloca() using alloca.c by adding it to LSRCS
* zap rcsid.espie2005-08-079-50/+9
| | | | okay deraadt@ (tested them all)
* Replace broken frexp() with a working one from FreeBSD. There'smillert2005-02-012-75/+1
| | | | | | no need to have a copy for each platform with ieee floating point, only vax needs a special version (which probably has similar bugs). OK and with help from otto@
* longjmp should not return 0, if longjmp(..., 0) is invoked return 1.drahn2004-03-011-2/+8
| | | | ok miod@ deraadt@
* These files are not necessary anymore.miod2003-09-011-29/+0

* Use a logical comparison (unsigned) for pointers. ok drahn@tdeval2003-07-101-2/+2
|
* terms 3 & 4 cleanup based on "terms" filederaadt2003-06-031-6/+1

* Remove the advertising clause in the UCB license which Berkeleymillert2003-06-025-33/+13
| | | | rescinded 22 July 1999. Proofed by myself and Theo.
* Add Doug Gwyn's portable alloca() for platforms w/o an assemblermillert2003-05-021-0/+1
| | | | | | | version. Normally, gcc provides its own alloca() (unless -fno-builtin is specified). The C version is decidedly suboptimal--we really need proper assembler versions but this will work as a stop-gap measure.
* Align this char array accessed as double, for paranoia reasons.drahn2003-01-291-3/+4
|
* Remove some old if 0/if 1 code, it is pointless to keep this in.drahn2002-10-241-16/+1
|
* kick, kick. Fix these files which did not come from NetBSD, but thedrahn2002-10-0714-6/+375
| | | | powerpc port by Dale Rahn.
* clean up ifdefs for PIC, resulting code unchanged.drahn2002-10-071-6/+3
|
* s/curbrk/__curbrk/ as suggested by art, a few _ASM_LABEL added as appropriate.drahn2002-10-072-14/+14
|
* Simpler, smaller, more efficient and equivalent.drahn2002-10-071-13/+2
|
* cerror -> __cerror as suggested by art, with a couple of missing _ASM_LABEL()drahn2002-10-076-10/+10
| | | | added as appropriate.
* make fabs use asm, and license repairderaadt2002-06-171-6/+32
|
* Sync with netbsd version, adds SOFTFLOAT (not supported) and copyright.drahn2002-05-081-2/+39
|
* OpenBSD tag.drahn2002-05-081-0/+1
|
* Add copyright block to this file I wrote long ago.drahn2002-05-081-0/+31
|
* We need to keep K&R compat macros for some ports where the assemnbler ismillert2002-02-192-6/+21
| | | | still using -traditional-cpp.
* We live in an ANSI C world. Remove lots of gratuitous #ifdef __STDC__ cruft.millert2002-02-192-21/+6

* rfork() needs a fork.S-like stub as well; ok artderaadt2002-02-171-0/+5
|
* Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.millert2002-02-161-65/+65

* sigprocmask should return 0 on success, fixes powerpc ntpdate problem.drahn2002-01-101-0/+1
|
* change PSEUDO_NOERROR so it is indeed does not set errno.drahn2001-09-201-3/+3
|
* Add PSEUDO_NOERROR similar to that used by NetBSD.millert2001-09-201-2/+7
| | | | | | | | | | | Some ports were setting errno in PSEUDO and some were not. Now errno is set for all in PSEUDO and PSEUDO_NOERROR is provided for the non-errno case (only used by _exit). Needs testing on vax and m88k. XXX - hppa and powerpc still lack a real PSEUDO_NOERROR implementation. Currently PSEUDO_NOERROR and PSEUDO are the same (so builds don't break on those platforms).
* Keep the strings fully quoted.drahn2001-09-111-2/+2
