Switch time_t, ino_t, clock_t, and struct kevent's ident and data members to 64bit types. Assign new syscall numbers for (almost all) the syscalls that involve the affected types, including anything with time_t, timeval, itimerval, timespec, rusage, dirent, stat, or kevent arguments. Add a d_off member to struct dirent and replace getdirentries() with getdents(), thus immensely simplifying and accelerating telldir/seekdir. Build perl with -DBIG_TIME. Bump the major on every single base library: the compat bits included here are only good enough to make the transition; the T32 compat option will be burned as soon as we've reached the new world are are happy with the snapshots for all architectures. DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead. Much assistance in fixing userland issues from deraadt@ and tedu@ and build assistance from todd@ and otto@

Switch libc and libm to use strong aliases rather than weak aliases where appropriate. Among other things makes the symbols consistent across all architectures (notably where ldbl mantissa is 53 bits). While at it, kill unused LINTLIBRARY/PROTOLIB1 cruft which was there to trick lint into recording the right prototypes for aliased functions. Most of the work done at the awesome n2k13 hackathon. Agreed by kettenis@, guenther@, matthew@.

Finalize work on the math library. It's time to do this monster commit, and deal with problems (if any) in tree. Note that this adds the following functions. 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@

- 80-bit and quad precision trigonometric and other most important 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 of changes to adapt. note, these are all c versions; and are quite slow when architectures have, e.g. sqrt. assembly versions will be added afterwards - make them .weak/__weak_alias to the double precision versions on other archs - 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 - remove unused infinity.c. the c library has infinities for each supported platform - use STRICT_ASSIGN cast hack for _kernel_rem_pio2, so that the double version has a chance of working on i386 with extra precision - avoid storing multiple copies of the pi/2 array, since it won't vary - bump major due to removed finite/finitef. although they will be in libc, which anything is linked to, minor bump might be enough ok 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 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,

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.
