* Retire hp300, mvme68k and mvme88k ports. These ports have no users, keepingmiod2014-03-18100-4130/+0
| | | | | | | this hardware alive is becoming increasingly difficult, and I should heed the message sent by the three disks which have died on me over the last few days. Noone sane will mourn these ports anyway. So long, and thanks for the fish.
* Userland bits for m68k/ELF. Mostly addition of register prefixes to themiod2013-02-0278-610/+637

* Convert cpp | as rules in bsd.lib.mk and lib/libc/sys/Makefile.inc to pure ccpascal2012-08-225-12/+12
| | | | | | | invocations. This allows us to use the compiler builtin define __PIC__ to check for PIC/PIEness rather than passing -DPIC. Simplifies PIE work a lot. ok matthew@, conceptually ok kurt@
* __tfork() needs to set the stack address of the new thread in the kernel,guenther2012-06-211-7/+6
| | | | | | | | | 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@

* 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@

* - add long double signbitmartynas2008-12-096-6/+38
| | | | | | | | | | | | | - make long double versions weak aliases to double versions, on archs where long doubles are 64 bits - no need to have two finites. finite() and finitef() are non-standard 3BSD obsolete versions of isfinite. remove from libm. make them weak_alias in libc to __isfinite and __isfinitef instead. similarly make 3BSD obsolete versions of isinf, isinff, isnan, isnanf weak_aliases to C99's __isinf, __isinff, __isnan, __isnanf - bump major ok millert@
* - replace dtoa w/ David's gdtoa, version 2008-03-15martynas2008-09-0710-1/+222
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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 754martynas2008-07-244-97/+12
| | | | | | | | | | | | | | | | - 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
* if we pull in a .S file, we must fake out the lint with a .c filederaadt2005-11-291-2/+5
| | | | | for this first cut, we will do this for alloca() using alloca.c by adding it to LSRCS

* Replace broken frexp() with a working one from FreeBSD. There'smillert2005-02-012-76/+2
| | | | | | 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@

* Move the weak definition from before the syscall's entry point tomillert2002-11-061-13/+11
| | | | | after. This avoids a bunch of reloc warnings by working around a deficiency in the a.out loader. miod@ OK
* thread safe libc -- 2nd try. OK miod@, millert@marc2002-11-051-18/+19
| | | | Thanks to miod@ for m68k and vax fixes
* Rename cerror to __cerror and curbrk to __curbrk, to avoid namespacemiod2002-11-059-28/+28

* libc changes for thread safety. Tested on:marc2002-11-031-13/+1
| | | | | | | alpha (millert@), i386 (marc@), m68k (millert@ and miod@), powerpc (drahn@ and dhartmei@), sparc (millert@ and marc@), sparc64 (marc@), and vax (millert@ and miod@). Thanks to millert@, miod@, and mickey@ for fixes along the way.
* Rewrite to get proper Copyright.espie2002-06-181-15/+40
| | | | | | Should even be slightly better than the old one. Checked and fixed by miod@, my initial version was not 100% right (writing m68k loops blindly doesn't always work).
* We need to keep K&R compat macros for some ports where the assemnbler ismillert2002-02-191-4/+12

* Fix incorrect number of args to __SYSCALL. Somehow this managed tomillert2001-09-211-9/+5
| | | | | work in my test on static libs -- I've no idea how though. While I'm here, remove __RSYSCALL since it is the same as __PSEUDO.
* Add PSEUDO_NOERROR similar to that used by NetBSD.millert2001-09-201-17/+30
| | | | | | | | | | | 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).
