From 319618ea76ca9de5c1e1b02bff3bddbdf5c46dc7 Mon Sep 17 00:00:00 2001 From: Martynas Venckus Date: Sun, 7 Sep 2008 20:36:11 +0000 Subject: - replace dtoa w/ David's gdtoa, version 2008-03-15 - 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 --- sys/arch/i386/include/ieee.h | 18 +++++++++++++----- 1 file changed, 13 insertions(+), 5 deletions(-) (limited to 'sys/arch/i386/include') diff --git a/sys/arch/i386/include/ieee.h b/sys/arch/i386/include/ieee.h index 55b3703277c..865fcb9eec6 100644 --- a/sys/arch/i386/include/ieee.h +++ b/sys/arch/i386/include/ieee.h @@ -1,4 +1,4 @@ -/* $OpenBSD: ieee.h,v 1.2 2003/06/02 23:27:47 millert Exp $ */ +/* $OpenBSD: ieee.h,v 1.3 2008/09/07 20:36:06 martynas Exp $ */ /* $NetBSD: ieee.h,v 1.1 1996/09/30 16:34:25 ws Exp $ */ /* @@ -79,10 +79,19 @@ #define SNG_FRACBITS 23 #define DBL_EXPBITS 11 +#define DBL_FRACHBITS 20 +#define DBL_FRACLBITS 32 #define DBL_FRACBITS 52 #define EXT_EXPBITS 15 -#define EXT_FRACBITS 112 +#define EXT_FRACHBITS 32 +#define EXT_FRACLBITS 32 +#define EXT_FRACBITS 64 + +#define EXT_TO_ARRAY32(p, a) do { \ + (a)[0] = (uint32_t)(p)->ext_fracl; \ + (a)[1] = (uint32_t)(p)->ext_frach; \ +} while(0) struct ieee_single { u_int sng_frac:23; @@ -99,11 +108,10 @@ struct ieee_double { struct ieee_ext { u_int ext_fracl; - u_int ext_fraclm; - u_int ext_frachm; - u_int ext_frach:16; + u_int ext_frach; u_int ext_exp:15; u_int ext_sign:1; + u_int ext_pad:16; }; /* -- cgit v1.2.3
