* remove from gen so that lint doesn't check gen if assembly versionsmartynas2009-04-211-2/+2
| | | | are available. spotted by theo
* - ldexp implementation has issues. switch to the one from libmmartynas2009-04-192-143/+2
| | | | | | - remove frexp in hppa64, cloned from hppa - move generic ieee754 implementations of modf and ldexp to gen ok kettenis@, "looks good" millert@

* - add long double signbitmartynas2008-12-092-4/+3
| | | | | | | | | | | | | - 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/+221
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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 754martynas2008-07-244-96/+11
| | | | | | | | | | | | | | | | - 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

* 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@
* In _longjmp(), flush windows rather than attempting to backtrack manually,miod2004-05-041-28/+19
| | | | | | | | | since the latter is not reliable in all cases. This allows ruby to work on sparc64. Problem spotted by claudio@; fix adapted from NetBSD for sparc, FreeBSD for sparc64; ok deraadt@

* Add Doug Gwyn's portable alloca() for platforms w/o an assemblermillert2003-05-021-1/+2
| | | | | | | 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.

* Two touches to make this work with ELF.art2002-08-112-31/+18
| | | | | - use _C_LABEL(__cerror) and not cerror to avoid polluting the name space. - Use weak symbols for libc_r syscalls.

* Add PSEUDO_NOERROR similar to that used by NetBSD.millert2001-09-201-9/+18
| | | | | | | | | | | 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).
