Sparc64 merge:
* configure.in: Change up subdirectories, rename sparc8->sparcv8.
* csu/Makefile: Nuke need-nopic-initfini bits. The problem was
that sparc64 ld did not recognize pic relocs at all.
* elf/dl-deps.c: Include <string.h>.
* elf/do-rel.h (elf_dynamic_do_rel): Take reloc address and size
directly instead of the DT names to get them from.
* elf/dynamic-link.h (_ELF_DYNAMIC_DO_RELOC): New macro distilled
from ELF_DYNAMIC_DO_REL{,A}. Define a second version that accounts
for the possibility that DT_RELA and DT_JMPPLT overlap, as such is
the case on the Sparc.
* elf/elf.h: Stub out Elf64_Ver*, and make them the same as the
Elf32_Ver* bits. The linker does not even know to differentiate
between the word sizes. Someone should examine this and figure
out what the proper sizes of things should be for 64-bit hosts
before the sparc64 libraries are distributed.
* shlib-versions: Rename sparc64 ld.so to not conflict with sparc32
on the same machine.
Move old sysdeps/sparc contents to sysdeps/sparc/sparc32,
rename sparc8 subdir to sparcv8, move sysdeps/sparc64 content to
sysdeps/sparc/sparc64. Same for sysdeps/unix/sysv/linux/sparc.

examples.

Sparc64 merge:

before the sparc64 libraries are distributed.

|
|
|
|
This chapter contains information about functions for performing
|
|
|
|
mathematical computations, such as trigonometric functions. Most of
|
|
|
|
these functions have prototypes declared in the header file
|
1998-07-13 12:29:13 +00:00
|
|
|
@file{math.h}. The complex-valued functions are defined in
|
|
|
|
@file{complex.h}.

All mathematical functions which take a floating-point argument
|
|
|
|
have three variants, one each for @code{double}, @code{float}, and
|
|
|
|
@code{long double} arguments. The @code{double} versions are mostly
|
1999-10-31 17:37:43 +00:00
|
|
|
defined in @w{ISO C89}. The @code{float} and @code{long double}
|
|
|
|
versions are from the numeric extensions to C included in @w{ISO C99}.
|
1998-07-13 12:29:13 +00:00
|
|
|
|
|
|
|
Which of the three versions of a function should be used depends on the
|
|
|
|
situation. For most calculations, the @code{float} functions are the
|
|
|
|
fastest. On the other hand, the @code{long double} functions have the
|
|
|
|
highest precision. @code{double} is somewhere in between. It is
|
1999-08-27 19:06:58 +00:00
|
|
|
usually wise to pick the narrowest type that can accommodate your data.
|
1998-07-13 12:29:13 +00:00
|
|
|
Not all machines have a distinct @code{long double} type; it may be the
|
|
|
|
same as @code{double}.

|
2016-11-14 16:36:18 +00:00
|
|
|
@code{_Float@var{N}x} types. These types are defined in @w{ISO/IEC TS
|
|
|
|
18661-3}, which extends @w{ISO C} and defines floating-point types that
|
|
|
|
are not machine-dependent. When such a type, such as @code{_Float128},

is supported by @theglibc{}, extra variants for most of the mathematical

provided for @code{_Float32}, @code{_Float64} and @code{_Float32x} on

all platforms.

Add _Float64x function aliases.
This patch continues filling out TS 18661-3 support by adding *f64x
function aliases on platforms with _Float64x support. (It so happens
the set of such platforms is exactly the same as the set of platforms
with _Float128 support, although on x86_64, x86 and ia32 the _Float64x
format is Intel extended rather than binary128.) The API provided
corresponds exactly to that provided for _Float128, mostly coming from
TS 18661-3. As these functions always alias those for another type
(long double, _Float128 or both), __* function names are not provided,
as in other cases of alias types.
Given the preparation done in previous patches, this one just enables
the feature via Makeconfig and bits/floatn.h, adds symbol versions,
and updates documentation and ABI baselines. The symbol versions are
present unconditionally as GLIBC_2.27 in the relevant Versions files,
as it's OK for those to specify versions for functions that may not be
present in some configurations; no additional complexity is needed
unless in future some configuration gains support for this type that
didn't have such support in 2.27. The Makeconfig additions for ia64
and x86 aren't strictly needed, as those configurations also get
float64x-alias-fcts definitions from
sysdeps/ieee754/float128/Makeconfig, but still seem appropriate given
that _Float64x is not _Float128 for those configurations.
A libm-test-ulps update for x86 is included. This is because
bits/mathinline.h does not have _Float64x support added and for two
functions the use of out-of-line functions results in increased ulps
(ifloat64x shares ulps with ildouble / ifloat128 as appropriate).
Given that we'd like generally to eliminate bits/mathinline.h
optimizations, preferring to have such optimizations in GCC instead,
it seems reasonable not to add such support there for new types. GCC
support for _FloatN / _FloatNx built-in functions is limited, but has
been improved in GCC 8, and at some point I hope the full set of libm
built-in functions in GCC, and other optimizations with
per-floating-type aspects, will be enabled for all _FloatN / _FloatNx
types.
Tested for x86_64 and x86, and with build-many-glibcs.py, with both
GCC 6 and GCC 7.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart
from the type, these functions behave the same as their float, double, and
long double counterparts. This patch adds the newer functions to the
manual.
* manual/arith.texi (Infinity and NaN): Document SNANFN and SNANFNx.
(Error Reporting by Mathematical Functions): Document HUGE_VAL_FN
and HUGE_VAL_FNx.
(Absolute Value): Document fabsfN, fabsfNx, cabsfN, cabsfNx.
Rephrase the paragraph that mentions that fabs, fabsf, and fabsl
are in math.h, to avoid having to list the _FloatN and _FloatNx
variants as well. Likewise for the cabs functions.
(Normalization Functions): Document frexpfN, frexpfNx, ldexpfN,
ldexpfNx, scalbnfN, scalbnfNx, scalblnfN, scalblnfNx.
Mention that _FloatN and _FloatNx variants of scalbn and scalbln
come from TS 18661-3, since this section explicitly states that
these functions come from BSD.
(Rounding Functions): Document ceilfN, ceilfNx, floorfN, floorfNx,
truncfN, truncfNx, rintfN, rintfNx, nearbyintfN, nearbyintfNx,
roundfN, roundfNx, roundevenfN, roundevenfNx, lrintfN, lrintfNx,

fromfpfN, fromfpfNx, ufromfpfN, ufromfpfNx, fromfpxfN, fromfpxfNx,
ufromfpxfN, ufromfpxfNx, modffN, modffNx.
(Remainder Functions): Document fmodfN, fmodfNx, remainderfN,
remainderfNx.
(Setting and modifying single bits of FP values): Document
copysignfN, copysignfNx, nextafterfN, nextafterfNx, nextupfN,
nextupfNx, nextdownfN, nextdownfNx, nanfN, nanfNx, canonicalizefN,
canonicalizefNx, getpayloadfN, getpayloadfNx, setpayloadfN,
setpayloadfNx, setpayloadsigfN, setpayloadsigfNx.
(Floating-Point Comparison Functions): Document totalorderfN,
totalorderfNx, totalordermagfN, totalordermagfNx.
(Miscellaneous FP arithmetic functions): Document fminfN, fminfNx,
fmaxfN, fmaxfNx, fminmagfN, fminmagfNx, fmaxmagfN, fmaxmagfNx,
fdimfN, fdimfNx, fmafN, fmafNx.
(Complex Numbers): Document the complex types: _FloatN complex and
_FloatNx complex.
(rojections, Conjugates, and Decomposing of Complex Numbers):
Document crealfN, crealfNx, cimagfN, cimagfNx, conjfN, conjfNx,
cargfN, cargfNx, cprojfN, cprojfNx.
* manual/math.texi (Mathematics): Mention that the _FloatN and
_FloatNx variants of the math functions come from TS 18661-3,
unless otherwise stated.
(Predefined Mathematical Constants): Document the _FloatN and
_FloatNx variants of the macros prefixed with M_.
(Trigonometric Functions): Document sinfN, sinfNx, cosfN, cosfNx,
tanfN, tanfNx, sincosfN, sincosfNx, csinfN, csinfNx, ccosfN,
ccosfNx, ctanfN, ctanfNx.
(Inverse Trigonometric Functions): Document asinfN, asinfNx,
acosfN, acosfNx, atanfN, atanfNx, atan2fN, atan2fNx.
(Exponentiation and Logarithms): Document expfN, expfNx, exp2fN,
exp2fNx, exp10fN, exp10fNx, logfN, logfNx, log10fN, log10fNx,

@vindex PI
|
|
|
|
@emph{Note:} Some programs use a constant named @code{PI} which has the
|
1998-07-13 12:29:13 +00:00
|
|
|
same value as @code{M_PI}. This constant is not standard; it may have
|
|
|
|
appeared in some old AT&T headers, and is mentioned in Stroustrup's book
|
2012-02-28 14:44:20 +00:00

on C++. It infringes on the user's name space, so @theglibc{}
|
1998-07-13 12:29:13 +00:00
|
|
|
does not define it. Fixing programs written to expect it is simple:
|
|
|
|
replace @code{PI} with @code{M_PI} throughout, or put @samp{-DPI=M_PI}
|
|
|
|
on the compiler command line.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

radians.
|
|
|
|
|
|
|

Mathematically, the tangent function has singularities at odd multiples
|
|
|
|
of pi/2. If the argument @var{x} is too close to one of these
|
1998-07-13 12:29:13 +00:00

singularities, @code{tan} will signal overflow.

In many applications where @code{sin} and @code{cos} are used, the sine

and cosine of the same angle are needed at the same time. It is more

|
efficient to compute them simultaneously, so the library provides a
|
|

|
function to do that.

wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart
from the type, these functions behave the same as their float, double, and
long double counterparts. This patch adds the newer functions to the
manual.
* manual/arith.texi (Infinity and NaN): Document SNANFN and SNANFNx.
(Error Reporting by Mathematical Functions): Document HUGE_VAL_FN
and HUGE_VAL_FNx.
(Absolute Value): Document fabsfN, fabsfNx, cabsfN, cabsfNx.
Rephrase the paragraph that mentions that fabs, fabsf, and fabsl
are in math.h, to avoid having to list the _FloatN and _FloatNx
variants as well. Likewise for the cabs functions.
(Normalization Functions): Document frexpfN, frexpfNx, ldexpfN,
ldexpfNx, scalbnfN, scalbnfNx, scalblnfN, scalblnfNx.
Mention that _FloatN and _FloatNx variants of scalbn and scalbln
come from TS 18661-3, since this section explicitly states that

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.
* manual/Makefile: Generate summary.texi with summary.pl.
Force use of the C locale. Update Perl dependency comment.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart
from the type, these functions behave the same as their float, double, and
long double counterparts. This patch adds the newer functions to the

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.
* manual/Makefile: Generate summary.texi with summary.pl.
Force use of the C locale. Update Perl dependency comment.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.
* manual/Makefile: Generate summary.texi with summary.pl.
Force use of the C locale. Update Perl dependency comment.

* manual/macros.texi: Refer authors to `summary.pl --help'.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.
* manual/Makefile: Generate summary.texi with summary.pl.
Force use of the C locale. Update Perl dependency comment.
* manual/header.texi: Update reference to summary.awk.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.
* manual/Makefile: Generate summary.texi with summary.pl.
Force use of the C locale. Update Perl dependency comment.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart
from the type, these functions behave the same as their float, double, and
long double counterparts. This patch adds the newer functions to the
manual.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

Add llogb, llogbf, llogbl.
TS 18661-1 defines llogb functions that are like ilogb except that
they return long int instead of int. Corresponding FP_LLOGB* macros
are defined, whose values are required to have the obvious
correspondence to those of the FP_ILOGB* macros.
This patch implements these functions and macros for glibc. llogb
uses the type-generic infrastructure, with an implementation similar
to the wrapper for ilogb but with additional conversion from FP_ILOGB*
to FP_LLOGB*; this approach avoids needing to modify or duplicate any
of the architecture-specific ilogb implementations. Tests are also
based on those for ilogb.
Ideally the llogb functions would alias the ilogb ones when long is
32-bit, but such aliasing requires the associated header declarations
of the different-type alias to be hidden, typically by defining macros
before including the header (see e.g. how
sysdeps/ieee754/dbl-64/wordsize-64/s_llround.c defines lround to
__hidden_lround before including <math.h>). The infrastructure for
type-generic function implementations does not support defining such
macros at present (since C code can't define a macro whose name is
determined by other macros). So this patch leaves them as separate
functions (similar to e.g. scalbln and scalbn being separate in such a
case as well), but with the remapping of FP_ILOGB* to FP_LLOGB*
conditioned out in the case where it would be the identity map.
Tested for x86_64, x86, mips64 and powerpc.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

These functions are equivalent to the corresponding @code{logb}
|
Add llogb, llogbf, llogbl.
TS 18661-1 defines llogb functions that are like ilogb except that
they return long int instead of int. Corresponding FP_LLOGB* macros
are defined, whose values are required to have the obvious
correspondence to those of the FP_ILOGB* macros.
This patch implements these functions and macros for glibc. llogb
uses the type-generic infrastructure, with an implementation similar
to the wrapper for ilogb but with additional conversion from FP_ILOGB*
to FP_LLOGB*; this approach avoids needing to modify or duplicate any
of the architecture-specific ilogb implementations. Tests are also
based on those for ilogb.
Ideally the llogb functions would alias the ilogb ones when long is
32-bit, but such aliasing requires the associated header declarations
of the different-type alias to be hidden, typically by defining macros
before including the header (see e.g. how
sysdeps/ieee754/dbl-64/wordsize-64/s_llround.c defines lround to
__hidden_lround before including <math.h>). The infrastructure for
type-generic function implementations does not support defining such
macros at present (since C code can't define a macro whose name is
determined by other macros). So this patch leaves them as separate
functions (similar to e.g. scalbln and scalbn being separate in such a
case as well), but with the remapping of FP_ILOGB* to FP_LLOGB*
conditioned out in the case where it would be the identity map.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

Add llogb, llogbf, llogbl.
TS 18661-1 defines llogb functions that are like ilogb except that
they return long int instead of int. Corresponding FP_LLOGB* macros
are defined, whose values are required to have the obvious
correspondence to those of the FP_ILOGB* macros.
This patch implements these functions and macros for glibc. llogb
uses the type-generic infrastructure, with an implementation similar
to the wrapper for ilogb but with additional conversion from FP_ILOGB*
to FP_LLOGB*; this approach avoids needing to modify or duplicate any
of the architecture-specific ilogb implementations. Tests are also
based on those for ilogb.
Ideally the llogb functions would alias the ilogb ones when long is
32-bit, but such aliasing requires the associated header declarations
of the different-type alias to be hidden, typically by defining macros
before including the header (see e.g. how
sysdeps/ieee754/dbl-64/wordsize-64/s_llround.c defines lround to
__hidden_lround before including <math.h>). The infrastructure for
type-generic function implementations does not support defining such
macros at present (since C code can't define a macro whose name is
determined by other macros). So this patch leaves them as separate
functions (similar to e.g. scalbln and scalbn being separate in such a
case as well), but with the remapping of FP_ILOGB* to FP_LLOGB*
conditioned out in the case where it would be the identity map.
Tested for x86_64, x86, mips64 and powerpc.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.
* manual/Makefile: Generate summary.texi with summary.pl.
Force use of the C locale. Update Perl dependency comment.

* manual/macros.texi: Refer authors to `summary.pl --help'.

Mathematically, @code{pow} would return a complex number when @var{base}

is negative and @var{power} is not an integral value. @code{pow} can't

do that, so instead it signals a domain error. @code{pow} may also

underflow or overflow the destination type.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.
* manual/Makefile: Generate summary.texi with summary.pl.
Force use of the C locale. Update Perl dependency comment.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.
* manual/Makefile: Generate summary.texi with summary.pl.
Force use of the C locale. Update Perl dependency comment.

* manual/macros.texi: Refer authors to `summary.pl --help'.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart
from the type, these functions behave the same as their float, double, and
long double counterparts. This patch adds the newer functions to the
manual.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.
* manual/Makefile: Generate summary.texi with summary.pl.
Force use of the C locale. Update Perl dependency comment.
* manual/header.texi: Update reference to summary.awk.
* manual/macros.texi: Refer authors to `summary.pl --help'.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart
from the type, these functions behave the same as their float, double, and
long double counterparts. This patch adds the newer functions to the
manual.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart
from the type, these functions behave the same as their float, double, and
long double counterparts. This patch adds the newer functions to the
manual.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart
from the type, these functions behave the same as their float, double, and
long double counterparts. This patch adds the newer functions to the
manual.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl

The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.
* manual/Makefile: Generate summary.texi with summary.pl.
Force use of the C locale. Update Perl dependency comment.
* manual/header.texi: Update reference to summary.awk.
* manual/macros.texi: Refer authors to `summary.pl --help'.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.
* manual/Makefile: Generate summary.texi with summary.pl.
Force use of the C locale. Update Perl dependency comment.
* manual/header.texi: Update reference to summary.awk.
* manual/macros.texi: Refer authors to `summary.pl --help'.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart
from the type, these functions behave the same as their float, double, and
long double counterparts. This patch adds the newer functions to the

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.
* manual/Makefile: Generate summary.texi with summary.pl.
Force use of the C locale. Update Perl dependency comment.
* manual/header.texi: Update reference to summary.awk.
* manual/macros.texi: Refer authors to `summary.pl --help'.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.

syntax of @standards. If errors are reported, the user is directed to

the gamma function of @var{x}. The gamma function is defined as
|
|
|
|
@tex

$$\Gamma(x) = \int_0^\infty t^{x-1} e^{-t} \hbox{d}t$$

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

Document _FloatN and _FloatNx versions of math functions
The functions defined in ISO/IEC TS 18661-3 take floating-point arguments
and return floating-point numbers of _FloatN and _FloatNx types. Apart
from the type, these functions behave the same as their float, double, and
long double counterparts. This patch adds the newer functions to the

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.
* manual/Makefile: Generate summary.texi with summary.pl.
Force use of the C locale. Update Perl dependency comment.
* manual/header.texi: Update reference to summary.awk.
* manual/macros.texi: Refer authors to `summary.pl --help'.

Refine documentation of libm exceptions goals.
This patch refines the math.texi documentation of the goals for when
libm function raise the inexact and underflow exceptions. The
previous text was problematic in some cases around the underflow
threshold.
* Strictly, it would have meant that if the mathematical result of pow
was very slightly below DBL_MIN, for example, it was required to
raise the underflow exception; although normally a few ulps error
would be OK, if that error meant the computed value was slightly
above DBL_MIN it would fail the previously described underflow
exception goal.
* Similarly, strict IEEE semantics would imply that sin (DBL_MIN), in
round-to-nearest mode, underflows on before-rounding but not
after-rounding architectures, while returning DBL_MIN; the previous
wording would have required an underflow exception, so preventing
checks for a result with absolute value below DBL_MIN from being
sufficient checks to determine whether the exception is required.
(Under the previous wording, checks for a result with absolute value
<= DBL_MIN wouldn't have been sufficient either, because in
FE_TOWARDZERO mode a result of DBL_MIN definitely does not result
from an underflowing infinite-precision result.)
* The previous wording about rounding infinite-precision values could
be taken to mean all exceptions including "inexact" must be
consistent with some such value. That would mean that a result of
DBL_MIN in FE_UPWARD mode with "inexact" raised must also have
"underflow" raised on before-rounding architectures. Again, that
would cause problems for computing a result (possibly with spurious
"inexact" exceptions) and then using a rounding-mode-independent
test for results with absolute value below DBL_MIN to determine
whether an underflow exception must be forced in case the underflows
from intermediate computations happened to be exact.
By refining the documentation, this patch avoids stating goals for
accuracy close to the underflow threshold that were stricter than
applied anywhere else, and allows the implementation strategy of:
compute a result within a few ulps, taking care to avoid underflows in
intermediate computations, then force an underflow exception if that
result was subnormal. Only fully-defined functions such as fma need
to take greater care about the exact underflow threshold (including
its dependence on whether the architecture is before-rounding or
after-rounding, and on the rounding mode on after-rounding
architectures).
(If the rounding mode is changed as part of the computation, it's
still necessary to ensure that not just intermediate computations, but
the final computation of the result to be returned, do not raise
underflow if that result is the least normal value and underflow would
be inconsistent with the original rounding mode. Since such code can
readily discard exceptions as part of saving and restoring the
rounding mode - SET_RESTORE_ROUND_NOEX etc. - I don't think that
should be a problem in practice.)

Where the mathematical result underflows (before rounding) and is not
|
|
|
|
exactly representable as a floating-point value, the function does not
|
|
|
|
behave as if the computed infinite-precision result is an exact value
|
|
|
|
in the subnormal range. This means that the underflow exception is
|
|
|
|
raised other than possibly for cases where the mathematical result is
|
|
|
|
very close to the underflow threshold and the function behaves as if
|
|
|
|
it computes an infinite-precision result that does not underflow. (So
|
|
|
|
there may be spurious underflow exceptions in cases where the
|
|
|
|
underflowing result is exact, but not missing underflow exceptions in
|
|
|
|
cases where it is inexact.)

Therefore many of the functions in the math library have errors. The

table lists the maximum error for each function which is exposed by one
|
2001-08-28 08:05:41 +00:00
|
|
|
of the existing tests in the test suite. The table tries to cover as much
|
|
|
|
as possible and list the actual maximum error (or at least a ballpark
|
1999-10-30 06:56:10 +00:00

figure) but this is often not achieved due to the large search space.
|

The table lists the ULP values for different architectures. Different

floating-point operations varies and also the existing hardware support
|
2017-02-06 17:55:59 +00:00
|

is different. Only the round-to-nearest rounding mode is covered by

this table, and vector versions of functions are not covered.

Functions not listed do not have known errors.

This section describes the GNU facilities for generating a series of
|
|
|
|
pseudo-random numbers. The numbers generated are not truly random;
|
1998-07-13 12:29:13 +00:00
|
|
|
typically, they form a sequence that repeats periodically, with a period
|
|
|
|
so large that you can ignore it for ordinary purposes. The random
|
|
|
|
number generator works by remembering a @dfn{seed} value which it uses
|
|
|
|
to compute the next random number and also to compute a new seed.
|
1995-02-18 01:27:10 +00:00
|
|
|
|
|
|
|
Although the generated numbers look unpredictable within one run of a
|
|
|
|
program, the sequence of numbers is @emph{exactly the same} from one run
|
|
|
|
to the next. This is because the initial seed is always the same. This
|
|
|
|
is convenient when you are debugging a program, but it is unhelpful if
|
1998-07-13 12:29:13 +00:00
|
|
|
you want the program to behave unpredictably. If you want a different
|
|
|
|
pseudo-random series each time your program runs, you must specify a
|
|
|
|
different seed each time. For ordinary purposes, basing the seed on the
|
2016-12-12 16:28:03 +00:00
|
|
|
current time works well. For random numbers in cryptography,

|
|
|
You can obtain repeatable sequences of numbers on a particular machine type
|
1995-02-18 01:27:10 +00:00
|
|
|
by specifying the same initial seed value for the random number
|
|
|
|
generator. There is no standard meaning for a particular seed value;
|
|
|
|
the same seed, used in different C libraries or on different CPU types,
|
|
|
|
will give you different random numbers.

@Theglibc{} supports the standard @w{ISO C} random number functions
|
1998-07-13 12:29:13 +00:00

plus two other sets derived from BSD and SVID. The BSD and @w{ISO C}
|

functions provide identical, somewhat limited functionality. If only a

small number of random bits are required, we recommend you use the
|
|

@w{ISO C} interface, @code{rand} and @code{srand}. The SVID functions
|
|
|
|
provide a more flexible interface, which allows better random number
|
|

generator algorithms, provides more random bits (up to 48) per call, and
|
|
|

can provide random floating-point numbers. These functions are required

The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and

Sparc64 merge:
* configure.in: Change up subdirectories, rename sparc8->sparcv8.
* csu/Makefile: Nuke need-nopic-initfini bits. The problem was
that sparc64 ld did not recognize pic relocs at all.
* elf/dl-deps.c: Include <string.h>.
* elf/do-rel.h (elf_dynamic_do_rel): Take reloc address and size
directly instead of the DT names to get them from.
* elf/dynamic-link.h (_ELF_DYNAMIC_DO_RELOC): New macro distilled
from ELF_DYNAMIC_DO_REL{,A}. Define a second version that accounts
for the possibility that DT_RELA and DT_JMPPLT overlap, as such is
the case on the Sparc.
* elf/elf.h: Stub out Elf64_Ver*, and make them the same as the
Elf32_Ver* bits. The linker does not even know to differentiate
between the word sizes. Someone should examine this and figure
out what the proper sizes of things should be for 64-bit hosts
before the sparc64 libraries are distributed.
* shlib-versions: Rename sparc64 ld.so to not conflict with sparc32
on the same machine.
Move old sysdeps/sparc contents to sysdeps/sparc/sparc32,
rename sparc8 subdir to sparcv8, move sysdeps/sparc64 content to
sysdeps/sparc/sparc64. Same for sysdeps/unix/sysv/linux/sparc.

the later does not exist when running ld.so directly.

The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

Sparc64 merge:
* configure.in: Change up subdirectories, rename sparc8->sparcv8.
* csu/Makefile: Nuke need-nopic-initfini bits. The problem was
that sparc64 ld did not recognize pic relocs at all.
* elf/dl-deps.c: Include <string.h>.
* elf/do-rel.h (elf_dynamic_do_rel): Take reloc address and size
directly instead of the DT names to get them from.
* elf/dynamic-link.h (_ELF_DYNAMIC_DO_RELOC): New macro distilled
from ELF_DYNAMIC_DO_REL{,A}. Define a second version that accounts
for the possibility that DT_RELA and DT_JMPPLT overlap, as such is
the case on the Sparc.
* elf/elf.h: Stub out Elf64_Ver*, and make them the same as the
Elf32_Ver* bits. The linker does not even know to differentiate
between the word sizes. Someone should examine this and figure
out what the proper sizes of things should be for 64-bit hosts
before the sparc64 libraries are distributed.
* shlib-versions: Rename sparc64 ld.so to not conflict with sparc32
on the same machine.
Move old sysdeps/sparc contents to sysdeps/sparc/sparc32,
rename sparc8 subdir to sparcv8, move sysdeps/sparc64 content to
sysdeps/sparc/sparc64. Same for sysdeps/unix/sysv/linux/sparc.

the later does not exist when running ld.so directly.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

The four functions described so far in this section all work on a state
|
|
|
|
which is shared by all threads. The state is not directly accessible to
|
|
|
|
the user and can only be modified by these functions. This makes it
|
|
|
|
hard to deal with situations where each thread should have its own
|
|
|
|
pseudo-random number generator.
|
|
|
|
|
2012-02-28 14:44:20 +00:00

@Theglibc{} contains four additional functions which contain the
|
2001-04-09 18:07:15 +00:00
|
|
|
state as an explicit parameter and therefore make it possible to handle
|
2016-10-06 06:41:07 +00:00
|
|
|
thread-local PRNGs. Besides this there is no difference. In fact, the
|
2001-04-09 18:07:15 +00:00
|
|
|
four functions already discussed are implemented internally using the
|
|
|
|
following interfaces.
|
|
|
|
|
|
|
|
The @file{stdlib.h} header contains a definition of the following type:
|
|
|
|
|
|
|
|
@deftp {Data Type} {struct random_data}
|
manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

@deftypefun {long int} lrand48 (void)

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.
* manual/Makefile: Generate summary.texi with summary.pl.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

This function is similar to the @code{lrand48} function in that it
|
|
|
|
returns a number in the range of @code{0} to @code{2^31} (exclusive) but
|
|
|
|
the state of the random number generator used to produce the random bits
|
|
|
|
is determined by the array provided as the parameter to the function.
|
|
|
|
|
1999-08-27 19:06:58 +00:00
|
|
|
The numbers in the array are updated afterwards so that subsequent calls
|
|
|
|
to this function yield different results (as is expected of a random
|
|
|
|
number generator). The array should have been initialized before the
|
|
|
|
first call to obtain reproducible results.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

All the above functions have in common that they use the global
|
|
|
|
parameters for the congruential formula. In multi-threaded programs it
|
|
|
|
might sometimes be useful to have different parameters in different
|
|
|
|
threads. For this reason all the above functions have a counterpart
|
|
|
|
which works on a description of the random number generator in the
|
|
|
|
user-supplied buffer instead of the global state.
|
|
|
|
|
|
|
|
Please note that it is no problem if several threads use the global
|
|
|
|
state if all threads use the functions which take a pointer to an array
|
|
|
|
containing the state. The random numbers are computed following the
|
|
|
|
same loop but if the state in the array is different all threads will
|
1999-08-27 19:06:58 +00:00
|
|
|
obtain an individual random number generator.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

This function is equivalent to the @code{drand48} function with the

|
|
difference that it does not modify the global random number generator

parameters but instead the parameters in the buffer supplied through the

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

If the return value is non-negative the function call succeeded.
|
|
|
|

|
|
|
This function is a GNU extension and should not be used in portable
|
|
|
|
programs.

If an application uses many floating point functions it is often the case
|
|
|
|
that the cost of the function calls themselves is not negligible.
|
|
|
|
Modern processors can often execute the operations themselves
|
|
|
|
very fast, but the function call disrupts the instruction pipeline.

For this reason @theglibc{} provides optimizations for many of the
|
1999-08-27 19:06:58 +00:00
|
|
|
frequently-used math functions. When GNU CC is used and the user
|
|
|
|
activates the optimizer, several new inline functions and macros are
|
1998-07-13 12:29:13 +00:00
|
|
|
defined. These new functions and macros have the same names as the
|
1999-08-27 19:06:58 +00:00
|
|
|
library functions and so are used instead of the latter. In the case of
|
1998-07-13 12:29:13 +00:00
|
|
|
inline functions the compiler will decide whether it is reasonable to
|
1999-08-27 19:06:58 +00:00
|
|
|
use them, and this decision is usually correct.
|

This means that no calls to the library functions may be necessary, and
|
|
|
|
can increase the speed of generated code significantly. The drawback is
|
|
|
|
that code size will increase, and the increase is not always negligible.

There are two kinds of inline functions: those that give the same result
|
2000-05-25 06:27:20 +00:00
|
|
|
as the library functions and others that might not set @code{errno} and
|
|
|
|
might have a reduced precision and/or argument range in comparison with
|
|
|
|
the library functions. The latter inline functions are only available
|
|
|
|
if the flag @code{-ffast-math} is given to GNU CC.

|
|
In cases where the inline functions and macros are not wanted the symbol
|
|
|
|
@code{__NO_MATH_INLINES} should be defined before any system header is
|
1999-08-27 19:06:58 +00:00
|
|
|
included. This will ensure that only library functions are used. Of
|
|
|
|
course, it can be determined for each file in the project whether
|
|
|
|
giving this option is preferable or not.
|
|
|
|
|
|
|
|
Not all hardware implements the entire @w{IEEE 754} standard, and even
|
|
|
|
if it does there may be a substantial performance penalty for using some
|
|
|
|
of its features. For example, enabling traps on some processors forces
|
|
|
|
the FPU to run un-pipelined, which can more than double calculation time.
