* 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,guenther2012-06-211-8/+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@
* alloca.c cannot be usedderaadt2012-04-121-3/+1
|
* remove rfork(); ok guenther miodderaadt2012-04-121-57/+0
|
* Move __tfork_thread() from rthreads (libpthread) to libc so thatguenther2012-03-221-0/+80
| | | | | | 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 dependingmartynas2011-07-083-2/+119
| | | | | on this historical behavior; so we're stuck in this stupid situation. No cookie for me.
* Kill weak `cerror' alias, it's colliding with the userland namespace. Noticedmiod2011-07-081-2/+1
| | | | by guenther@ months ago, had to wait for a libc major bump.
* Move fabs(3), frexp(3), and modf(3) to libm--nothing has been usingmartynas2011-07-083-119/+2
| | | | them in libc for a very long time. OK guenther@.
* Fix the previous commit: define ___cerror, no __cerrorguenther2011-04-051-4/+4
| | | | tested by otto@; ok miod@
* Move __cerror to ___cerror with a weak alias so that rthreads can override it.guenther2011-04-0412-27/+33
| | | | | | 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 platformsguenther2010-10-011-3/+3
| | | | | | | that didn't already have one, and then immediately use it in libc's SYS.h ok miod@
* Provide IRIX-compatible get_fpc_csr() and set_fpc_csr() for mips, althoughmiod2010-09-242-2/+46
| | | | | | | | we don't provide the silly union to decompose the value. This will allow userland to flip the ``flush denormalized to zero'' setting, which apparently is being relied upon by tcl. Asked by jasper@ a long time ago. Riding upon the upcoming libc major crank.
* Give little-endian fp on mips a change to be handled correctly.miod2010-01-231-0/+4
|
* More changes to avoid truncating 64 bit pointers to 32 bits and sign-extendingmiod2009-12-118-69/+69
| | | | them; allows userland with stack beyond 2GB to run.
* Use a local numeric label to branch to the start of the function, instead ofmiod2009-11-011-2/+3
| | | | referencing it by name; silences a linker warning; no functional change.
* more rcsid/sccs cleanupderaadt2009-10-282-10/+0
|
* Add an implementation of IRIX-compatible cacheflush() routine to mips ports,miod2009-09-272-1/+39
| | | | | | | needed for gcc -ftrampoline operation as well as by some third-party software. Although the implementation uses the sysarch() sysctl, the wrapper is added to libc as it was a direct system call (which it is on IRIX).
* Load symbol address with dla, not la; good thing userland is still limitedmiod2009-07-131-2/+2
| | | | to 2GB of vm space.
* these were not neededmartynas2008-12-091-2/+1
|
* ditto frexpl and ldexplmartynas2008-12-091-1/+2

* - 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 2008-03-15martynas2008-09-0711-4/+227
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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
* fix apps that use isinff, isnanf; use ieee 754 mi code, as allmartynas2008-07-253-119/+2
| | | | other ieee fp archs do; pointed out by theo. tested by theo
* - move isinf, isnan dups to gen, since most is ieee 754martynas2008-07-244-30/+81
| | | | | | | | | | | | | | | | - 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 filederaadt2005-11-291-1/+2
| | | | | for this first cut, we will do this for alloca() using alloca.c by adding it to LSRCS
* zap rcsid.espie2005-08-0736-174/+36
| | | | okay deraadt@ (tested them all)
* 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@
