![[BACK]](/icons/back.gif){kind=icon}
Define new C99 macros:
- MATH_ERRNO, MATH_ERREXCEPTION and math_errhandling
- Optional FP_FAST_FMA{,F,L} macros if fma() executes as fast or faster
than (x * y) + z; which in practice is achievable if gcc implements
__FP_FAST_FMA{,F,L}

Ports with hacks might need adjustments. nexttoward(3), fma(3), nexttowardf(3), fmaf(3), acoshl(3), asinhl(3), atanhl(3), coshl(3), sinhl(3), tanhl(3), expl(3), expm1l(3), logl(3), log10l(3), log1pl(3), log2l(3), modfl(3), cbrtl(3), hypotl(3), powl(3), erfl(3), erfcl(3), lgammal(3), tgammal(3), ceill(3), floorl(3), lrintl(3), llrintl(3), roundl(3), lroundl(3), llroundl(3), truncl(3), fmodl(3), remainderl(3), remquol(3), nextafterl(3), nexttowardl(3), fmal(3). With this commit, our library implements all functionality required by C99. Documentation bits will follow.

int is big enough to fully represent exponents of all supported fp formats. which even for 80-bit & 128-bit long doubles is only 15 bits. therefore, scalbln, scalblnf, scalblnl are essentially the same as scalbn, scalbnf, scalbnl with bounds checking so that LONG_MIN..INT_MIN, and INT_MAX..LONG_MAX ranges properly raise exceptions & yield correct values. looks good to millert@

- 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.
