The inspiration and name of MACHINE_CPU come from NetBSD, although the way to
provide it to Makefiles is completely different.

is getting ridiculous. split them into groups of copysign, ilogb,
nextafter, scalbn. discussed long ago with millert@
|
|
|
|
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@

faster that way. tested by myself. discussed w/ & ok miod@, millert@

from asm.h. discussed w/ millert@

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

- 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

parts of the diff ok kettenis@
this commit does not include:
- man page changes
|
|
for remquof.3;
|
|
- mlink drem, dremf, remainderf to remainder; nanf to nan
- describe that drem and dremf are obsolete aliases
- remove descriptions for remainder and remainderf from ieee
looked over by jmc@, but it's easier for him to work on when they
are in tree
|
|
|
|
|
|
- remove never-enabled signbit. libc has is now
- add C99 implementations, from freebsd, for nan(), nanf() (needed
to write _digittoint for it), exp2(), exp2f(), remquo(), remquof(),
needed STRICT_ASSIGN macro for math_private.h
- bump major
man pages will follow
exp2{,f} has been requested by chl@

s_lroundf.c s_llround.c s_llroundf.c, for naming consistency

lgamma.3: fix STANDARDS and HISTORY
|
|
- make gamma an alias of lgamma
- on ieee, add tgamma, based on gamma from non-ieee
- fixes for tgamma/lgamma/exp/log, esp. special cases (some from
freebsd); properly raise invalid fp operations on vax
- also some general cleanup, ansification, man page (which was ok
jmc@)
- bump minor
this makes some ports using tgamma possible; also consistifies
behavior across openbsd/ieee and openbsd/non-ieee, and other operating
systems
much thanks sthen@, johan@, steven@, Simon Kuhnle, Wiktor Izdebski
for testing
ok millert@
|
|
- document and mlink drem{,f}
- drem->remainder on noieee, and make drem an alias
- finite returns integer, n_support.c
- general n_support.c ansification and cleanup
- drem is now an ALTENTRY for remainder, in n_support.S

reasons for this, quite a few of them technical, and not all of them
in response to Intel's broken ia32e crud. The gcc toolchain stays at
x86_64 for now.
|
|
Instead of mixing the i387 & xmm register components, we decide to
explicitly seperate them. libm is already confusing enough as it is,
thank you very much
