At some point we've switched to the VFP floating-point--unlike FPAit actually stores floats in natural-endian--therefore the existingchecks became wrong.Take into account __VFP_FP__, effectively bringing back the oldbehavior. This way it will work now, and in the future when someof our platforms are switched to FPA, where it's much faster.

- 80-bit and quad precision trigonometric and other mostimportant functions: acosl, asinl, atanl, atan2l, cosl,sinl, tanl, exp2l, frexpl, ilogbl, ldexpl, logbl, scalbnl,fabsl, hypotl, powl, sqrtl, rintl, copysignl, nanl, fdiml,fmaxl, fminl. mostly taken from freebsd, needed alot ofchanges to adapt. note, these are all c versions; and arequite slow when architectures have, e.g. sqrt. assemblyversions will be added afterwards- make them .weak/__weak_alias to the double precisionversions on other archs- no need to have two finites. finite() and finitef() arenon-standard 3BSD obsolete versions of isfinite. removefrom libm. make them weak_alias in libc to __isfinite and__isfinitef instead. similarly make 3BSD obsolete versionsof isinf, isinff, isnan, isnanf weak_aliases to C99's__isinf, __isinff, __isnan, __isnanf- remove unused infinity.c. the c library has infinitiesfor each supported platform- use STRICT_ASSIGN cast hack for _kernel_rem_pio2, so thatthe double version has a chance of working on i386 withextra precision- avoid storing multiple copies of the pi/2 array, sinceit won't vary- bump major due to removed finite/finitef. although theywill be in libc, which anything is linked to, minor bumpmight be enoughok millert@. tested by sthen@, jsg@, ajacoutot@, kili@, naddy@

- 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 isfixed- 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 mistakesin SVID, etc.; use ieee versions. fixes issues in python 2.6 fordjm@- 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.hfor 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&ldtoato use- add EXT_IMPLICIT_NBIT definition, which indicates implicitnormalization 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 itreally 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 froma day agodiscussed 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 Revision1.9 / (download) -annotate -[select for diffs],Thu Jul 24 09:40:16 2008 UTC (17 years, 4 months ago) bymartynas
