614d15f932 Support _Float128 in tgmath.h. 
This patch adds tgmath.h support for _Float128, so eliminating the
awkward caveat in NEWS about the type not being supported there.  This
does inevitably increase the size of macro expansions (which grows
particularly fast when you have nested calls to tgmath.h macros), but
only when _Float128 is supported and the declarations of _Float128
interfaces are visible; otherwise the expansions are unchanged.

Tested for x86_64 and arm.

	* math/tgmath.h: Include <bits/libc-header-start.h> and
	<bits/floatn.h>.
	(__TGMATH_F128): New macro.

0908a38adc Use clog10 not __clog10 in tgmath.h log10 macro. 
As a GNU extension, for _GNU_SOURCE glibc's complex.h provides a
clog10 function and tgmath.h supports complex arguments to the log10
macro.  However, tgmath.h uses __clog10 not clog10 in defining the
macro.

There is no namespace reason (ignoring the block-scope namespace
issues that would apply equally to *every* function called by tgmath.h
macros) for using __clog10 here, since this is only for _GNU_SOURCE so
clog10 is always visible when this macro definition is used.
Furthermore, __clog10f128 is not exported, so supporting _Float128 in
tgmath.h implies using clog10 not __clog10 there.  (__clog10 and
clog10 aren't used in libstdc++ either, although that library would
have a good case for using the __clog10 reserved-namespace export: the
standard C++ library includes log10 of a complex number.)  This patch
duly changes the header to use clog10, and enables tests of the macro
for complex arguments.

Tested for x86_64.

	* math/tgmath.h [__USE_GNU] (log10): Use clog10 not __clog10.
	* math/gen-tgmath-tests.py (Tests.add_all_tests): Test log10 for
	complex arguments.

d12a22c5d3 Fix tgmath.h totalorder, totalordermag return type (bug 21687). 
The tgmath.h totalorder and totalordermag macros wrongly return a
floating-point type.  They should return int, like the underlying
functions.  This patch fixes them accordingly, updating tests
including enabling tests of those functions from gen-tgmath-tests.py.

Tested for x86_64.

cfa4434523 Simplify tgmath.h for integer return types. 
The tgmath.h macros for function with integer return types generate
unnecessary casts to the return type.  Since in those cases the return
type does not depend on the argument type, all the cases in the
conditional expressions already have the right type, and no casts are
needed; this patch removes them.

Tested for x86_64.

51737193a9 Remove NO_LONG_DOUBLE conditionals in libm tests (bug 21607). 
As noted in bug 21607, NO_LONG_DOUBLE conditionals in libm tests are
no longer effective.  For most this is harmless - they were only
present because of long double functions not being declared with _LIBC
defined, and _LIBC is no longer defined for building most tests.  For
the few where this is actually relevant to the test, testing
LDBL_MANT_DIG > DBL_MANT_DIG is more appropriate as that limits the
test to public APIs.  This patch fixes the tests accordingly.

Tested for x86_64 and arm.

2dd0aec531 Add more thorough generated tgmath.h test. 
This patch adds a more thorough test of tgmath.h macros, verifying
both the return type and the function called for all the cases of
valid argument types.  (Cases with current problems - I've just filed
four bugs - are disabled or omitted pending fixing those problems.)
The test uses a Python generator (works with both Python 2 and 3) to
generate a C file which is then built and run as a test in the usual
way (and that C file includes its own dummy definitions of libm
functions similar to existing tgmath.h tests).  The motivation is to
make it easier to add tests of tgmath.h for _Float128 when adding
tgmath.h support for that type; the _FloatN / _FloatNx support is
present in the script, but disabled until the tgmath.h support is
written.

Tested for x86_64, and for arm to check things in the long double =
double case.  (In that case, it's OK to call either double or long
double functions when the selected type is double or long double, as
long as the return type of the macro is exactly correct.)

	* math/gen-tgmath-tests.py: New file.

034e738021 Add float128 support for ia64. 
This patch enables float128 support for ia64, so that all the
configurations where GCC supports _Float128 / __float128 as an
ABI-distinct type now have glibc support as well.  bits/floatn.h
declares the support to be available for GCC 4.4 and later, which is
when the libgcc support was added.  The removal of
sysdeps/ia64/fpu/k_rem_pio2.c is because the generic k_rem_pio2.c
defines a function required by the float128 code.

Tested (compilation only) with build-many-glibcs.py for ia64 (GCC 6
and GCC 7).

Given how long it is since libm-test-ulps has been updated for ia64, I
think truncating the file and regenerating it from scratch would be a
good idea when doing a regeneration to add float128 ulps.  I expect
various ia64 libm issues (at least some already filed in Bugzilla) to
result in test failures even after ulps regeneration, but hopefully
the float128 code will pass tests as it's the same as used on other
architectures.

	* sysdeps/ia64/Implies: Add ieee754/float128.

c86ed71d63 Add float128 support for x86_64, x86. 
This patch enables float128 support for x86_64 and x86.  All GCC
versions that can build glibc provide the required support, but since
GCC 6 and before don't provide __builtin_nanq / __builtin_nansq, sNaN
tests and some tests of NaN payloads need to be disabled with such
compilers (this does not affect the generated glibc binaries at all,
just the tests).  bits/floatn.h declares float128 support to be
available for GCC versions that provide the required libgcc support
(4.3 for x86_64, 4.4 for i386 GNU/Linux, 4.5 for i386 GNU/Hurd);
compilation-only support was present some time before then, but not
really useful without the libgcc functions.

fenv_private.h needed updating to avoid trying to put _Float128 values
in registers.  I make no assertion of optimality of the
math_opt_barrier / math_force_eval definitions for this case; they are
simply intended to be sufficient to work correctly.

Tested for x86_64 and x86, with GCC 7 and GCC 6.  (Testing for x32 was
compilation tests only with build-many-glibcs.py to verify the ABI
baseline updates.  I have not done any testing for Hurd, although the
float128 support is enabled there as for GNU/Linux.)

48273d42bc Make libm-test-support code clear exceptions after each test. 
The libm-test-support code clears exceptions at the end of
test_exceptions.  However, it's possible that exceptions get raised as
part of the subsequent checks on the results of the function being
tested, and such exceptions then carry through to the next test run
and can cause that to fail spuriously.  In particular, it's possible
for the ulps calculation to raise exceptions in some cases.  This
patch puts exception clearing at the end of each of the check_*
functions, alongside errno clearing, to avoid one test affecting the
next in that way.

Tested for x86_64 (in conjunction with float128 patches).

46d2e49c49 Make errno-setting libm templates include errno.h. 
Various type-generic libm wrapper templates, as used for float128, set
errno but do not include errno.h.  I presume they must get an implicit
include from some internal header on powerpc64le; they don't get such
an implicit include on x86_64.  This patch adds the missing includes
of errno.h to each such wrapper.

7620dc1235 Convert e_exp2l.c into a template 
This patch converts the implementation of exp2l in math/e_exp2l.c into
a template in math/e_exp2_template.c, then adjusts Makefile to use
this template for long double (the implementations for float and
double in sysdeps have higher precedence and are not used).  This
template can also be used for float128, thus reducing the amount of
duplicated code that gets added when adding support the new type.

Tested for powerpc64le and s390x.

7c3018f9e4 Suppress internal declarations for most of the testsuite. 
This patch adds a new build module called 'testsuite'.
IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus
(which means several ad-hoc tests for __cplusplus can go away).
libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is
defined; in particular, _ISOMAC mode does not get config.h
automatically anymore.

There are still quite a few tests that need to see internal gunk of
one variety or another.  For them, we now have 'tests-internal' and
'test-internal-extras'; files in this category will still be compiled
with MODULE_NAME=nonlib, and everything proceeds as it always has.
The bulk of this patch is moving tests from 'tests' to
'tests-internal'.  There is also 'tests-static-internal', which has
the same effect on files in 'tests-static', and 'modules-names-tests',
which has the *inverse* effect on files in 'modules-names' (it's
inverted because most of the things in modules-names are *not* tests).
For both of these, the file must appear in *both* the new variable and
the old one.

There is also now a special case for when libc-symbols.h is included
without MODULE_NAME being defined at all.  (This happens during the
creation of libc-modules.h, and also when preprocessing Versions
files.)  When this happens, IS_IN is set to be always false and
_ISOMAC is *not* defined, which was the status quo, but now it's
explicit.

The remaining changes to C source files in this patch seemed likely to
cause problems in the absence of the main change.  They should be
relatively self-explanatory.  In a few cases I duplicated a definition
from an internal header rather than move the test to tests-internal;
this was a judgement call each time and I'm happy to change those
however reviewers feel is more appropriate.

	* Makerules: New subdir configuration variables 'tests-internal'
	and 'test-internal-extras'.  Test files in these categories will
	still be compiled with MODULE_NAME=nonlib.  Test files in the
	existing categories (tests, xtests, test-srcs, test-extras) are
	now compiled with MODULE_NAME=testsuite.
	New subdir configuration variable 'modules-names-tests'.  Files
	which are in both 'modules-names' and 'modules-names-tests' will
	be compiled with MODULE_NAME=testsuite instead of
	MODULE_NAME=extramodules.
	(gen-as-const-headers): Move to tests-internal.
	(do-tests-clean, common-mostlyclean): Support tests-internal.
	* Makeconfig (built-modules): Add testsuite.
	* Makefile: Change libof-check-installed-headers-c and
	libof-check-installed-headers-cxx to 'testsuite'.
	* Rules: Likewise.  Support tests-internal.
	* benchtests/strcoll-inputs/filelist#en_US.UTF-8:
	Remove extra-modules.mk.

	* config.h.in: Don't check for __OPTIMIZE__ or __FAST_MATH__ here.
	* include/libc-symbols.h: Move definitions of _GNU_SOURCE,
	PASTE_NAME, PASTE_NAME1, IN_MODULE, IS_IN, and IS_IN_LIB to the
	very top of the file and rationalize their order.
	If MODULE_NAME is not defined at all, define IS_IN to always be
	false, and don't define _ISOMAC.
	If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are
	true, define _ISOMAC and suppress everything else in this file,
	starting with the inclusion of config.h.
	Do check for inappropriate definitions of __OPTIMIZE__ and
	__FAST_MATH__ here, but only if _ISOMAC is not defined.
        Correct some out-of-date commentary.

	* include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE
	and _Mlong_double_ before including math.h.
	* include/string.h: If _ISOMAC is defined, don't expose
	_STRING_ARCH_unaligned. Move a comment to a more appropriate
	location.

	* include/errno.h, include/stdio.h, include/stdlib.h, include/string.h
	* include/time.h, include/unistd.h, include/wchar.h: No need to
	check __cplusplus nor use __BEGIN_DECLS/__END_DECLS.

	* misc/sys/cdefs.h (__NTHNL): New macro.
	* sysdeps/m68k/m680x0/fpu/bits/mathinline.h
	(__m81_defun): Use __NTHNL to avoid errors with GCC 6.

	* stdlib/tst-strtod5i.c: ...this new file.
	* string/test-string.h: Include stdint.h. Duplicate definition of
	inhibit_loop_to_libcall here (from libc-symbols.h).
	* string/test-strstr.c: Provide dummy definition of
	libc_hidden_builtin_def when including strstr.c.
	* sysdeps/ia64/fpu/libm-symbols.h: Suppress entire file in _ISOMAC
	mode; no need to test __STRICT_ANSI__ nor __cplusplus as well.
	* sysdeps/x86_64/fpu/math-tests-arch.h: Include cpu-features.h.

2072f5c34e Remove C++ namespace handling from glibc headers. 
glibc headers include some code (not particularly consistent or
systematic) to put various declarations in C++ namespaces std and
__c99, if _GLIBCPP_USE_NAMESPACES is defined.

As noted in <https://gcc.gnu.org/ml/libstdc++/2017-03/msg00025.html>,
this macro was removed from libstdc++ in 2000.  I don't expect
compilation with such old versions of libstdc++ to work with current
glibc headers anyway (whereas old *binaries* are expected to stay
working with current glibc); this patch (which should be a no-op with
any libstdc++ version postdating that removal) removes all this code
from the glibc headers.

The begin-end-check.pl test, whose comments say it is about checking
these namespace macro calls, is also removed.  The code in that test
would have covered __BEGIN_DECLS / __END_DECLS as well, but if those
weren't properly matched it would show up with the
check-installed-headers-cxx tests, so I don't think there is an actual
use for keeping begin-end-check.pl with the namespace code removed.

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

e4e52ff059 Improve float range reduction accuracy near pi/2 (bug 21094). 
Bug 21094 reports 3ulp errors of cosf and tanf for certain arguments
near pi/2 arising from the use of an insufficiently accurate range
reduction.  (To be clear, this is a quality-of-implementation issue
relating to the apparent intent of those particular cosf and tanf
implementations; 3ulp is within the general glibc accuracy goals, so
not inherently a bug.)

This patch fixes that error by making a wider range of cases use the
existing more accurate range reduction for arguments close to pi/2.
The wider range of values is still narrow enough for the "z -=
pio2_2;" in the more accurate case to be exact, as the code expects.

Tested for x86_64, x86 and mips64; no ulps updates needed (but at
least on mips64, the larger ulps were seen if the tests were added
without the substantive fix).

issignaling, and signbit are defined by ISO C11 and declared in
mathcalls.h for each of the floating-point types: float, double, and
long double.

TS 18661-3 does not mention these macros for float128, however support
for them must be present when _Float128 is present.  This is true,
even when the feature test macro __STDC_WANT_IEC_60559_TYPES_EXT__ is
false.  Other function declarations in mathcalls.h, on the other hand,
depend on __STDC_WANT_IEC_60559_TYPES_EXT__.

This patch splits the helper functions (__finite, __fpclassify,
__iseqsig, __isinf, __isnan, __issignaling, and __signbit) from
mathcalls.h, so that these helper functions can be declared for
_Float128, even when __STDC_WANT_IEC_60559_TYPES_EXT__ is false.

Tested for powerpc64le, s390x, and x86_64.

	* include/bits/mathcalls-helper-functions.h: New file.
	* math/Makefile (headers): Add bits/mathcalls-helper-functions.h.
	* math/bits/mathcalls.h (__finite, __fpclassify, __iseqsig)
	(__isinf, __isnan, __issignaling, __signbit): Move declarations to
	math/bits/mathcalls-helper-functions.h.
	* math/bits/mathcalls-helper-functions.h: New file.
	* math/math.h: Include bits/mathcalls-helper-functions.h for
	float, double, and long double.

826aa1346f Use internal __feraiseexcept in __iseqsig 
Replace the use of feraiseexcept with __feraiseexcept in the helper
function __iseqsig (math/s_iseqsig_template.c).

Tested for powerpc64le, s390x, and x86_64.

	* math/s_iseqsig_template.c (__iseqsig): Use __feraiseexcept
	instead of feraiseexcept.

93adfe2d79 Update auto-libm-test-out for catan / catanh. 
I've used gmp 6.1.2, mpfr 3.1.5 and upstream mpc with fix in mpc_atan
(https://scm.gforge.inria.fr/anonscm/gitweb?p=mpc/mpc.git;a=commit;h=958aac9b15a659d6fb5edcb11778123f8a35b14f)
to build gen-auto-libm-tests and regenerated  catan / catanh out files.
Regenerated ULPs for s390 from scratch.  Now the catan / catanh tests
are passing.

ChangeLog:

	* math/auto-libm-test-out-catan: Regenerated.
	* math/auto-libm-test-out-catanh: Likewise.
	* sysdeps/s390/fpu/libm-test-ulps: Likewise.

5e4e10636c Miscellaneous low-risk changes preparing for _ISOMAC testsuite. 
These are a grab bag of changes where the testsuite was using internal
symbols of some variety, but this was straightforward to fix, and the
fixed code should work with or without the change to compile the
testsuite under _ISOMAC.

Four of these are just more #include adjustments, but I want to highlight
sysdeps/powerpc/fpu/tst-setcontext-fpscr.c, which appears to have been
written before the advent of sys/auxv.h.  I think a big chunk of this file
could be replaced by a simple call to getauxval, but I'll let someone who
actually has a powerpc machine to test on do that.

dlfcn/tst-dladdr.c was including ldsodefs.h just so it could use
DL_LOOKUP_ADDRESS to print an additional diagnostic; as requested by Carlos,
I have removed this.

math/test-misc.c was using #ifndef NO_LONG_DOUBLE, which is an internal
configuration macro, to decide whether to do certain tests involving
'long double'.  I changed the test to #if LDBL_MANT_DIG > DBL_MANT_DIG
instead, which uses only public float.h macros and is equivalent on
all supported platforms.  (Note that NO_LONG_DOUBLE doesn't mean 'the
compiler doesn't support long double', it means 'long double is the
same as double'.)

tst-writev.c has a configuration macro 'ARTIFICIAL_LIMIT' that the
Makefiles are expected to define, and sysdeps/unix/sysv/linux/Makefile
was using the internal __getpagesize in the definition; changed to
sysconf(_SC_PAGESIZE) which is the POSIX equivalent.

ia64-linux doesn't supply 'clone', only '__clone2', which is not
defined in the public headers(!)  All the other clone tests have local
extern declarations of __clone2, but tst-clone.c doesn't; it was
getting away with this because include/sched.h does declare __clone2.

	* nss/tst-cancel-getpwuid_r.c: Include nss.h.
	* string/strcasestr.c: No need to include config.h.
	* sysdeps/powerpc/fpu/tst-setcontext-fpscr.c: Include
	sys/auxv.h. Don't include sysdep.h.
	* sysdeps/powerpc/tst-set_ppr.c: Don't include dl-procinfo.h.

	* dlfcn/tst-dladdr.c: Don't include ldsodefs.h.	 Don't use
	DL_LOOKUP_ADDRESS.
	* math/test-misc.c: Instead of testing NO_LONG_DOUBLE, test whether
	LDBL_MANT_DIG is greater than DBL_MANT_DIG.
	* sysdeps/unix/sysv/linux/Makefile (CFLAGS-tst-writev.c): Use
	sysconf (_SC_PAGESIZE) instead of __getpagesize in definition
	of ARTIFICIAL_LIMIT.
	* sysdeps/unix/sysv/linux/tst-clone.c [__ia64__]: Add extern
	declaration of __clone2.

92061bb033 Run libm tests separately for each function. 
At present, libm tests for each function get built into a single
executable (for each floating point type, for each of normal / inline
/ finite-math-only functions, plus vector variants) and run together,
resulting in a single PASS or FAIL (for each of those nine variants
plus vector variants).  Building this executable involves reading
over 50 MB of libm-test-*.c sources.

This patch arranges for tests of each function to be run separately
from the makefiles instead.  There are 121 functions being tested for
each (type, variant pair) (actually 126, but run as 121 from the
Makefile because each of the pairs (exp10, pow10), (isfinite, finite),
(lgamma, gamma), (remainder, drem), (scalbn, ldexp), shares a table of
test results and so is run together), so 1089 separate tests run from
the Makefile, plus 48 vector tests on x86_64 (six functions for eight
vector variants).  Each test only involves a libm-test-<func>.c file
of no more than about 4 MB, rather than all such files taking about 50
MB.  With tests run separately, test summaries will indicate which
functions actually have problems (of course, those problems may just
be out-of-date libm-test-ulps files if the file hasn't been updated
for the architecture in question recently).

All the .c files for the 1089+48 tests are generated automatically
from the Makefiles.  Various checked-in boilerplate .c files are
removed as no longer needed.  CFLAGS definitions for the different
kinds of tests are generated using makefile iterators to apply
target-specific variable settings.  libm-have-vector-test.h is no
longer needed; the list of functions to test for each vector type is
now in the sysdeps Makefile.

This should reduce the amount of boilerplate needed for float128
testing support; test-float128.h will still be needed, but not various
.c files or Makefile CFLAGS definitions.  The logic for creating
dependencies on libm-test-support-*.o files should also render
<https://sourceware.org/ml/libc-alpha/2017-02/msg00279.html>
unnecessary.

This patch removes some libm-test-support.h macros for exceptions that
are no longer used.  EXCEPTIONS_OK has been unused for some time.  The
macros for underflow exceptions with some types only were used when
the results for complex inverse trig and hyperbolic functions were
manually maintained, but are no longer needed now the auto-libm-test
machinery is used to determine the correct result and exceptions for
every floating-point format and rounding mode.

b4e4172da6 Move INIT_ARCH_EXT call from libm-test-support to libm-test-driver. 
libmvec tests involve calling INIT_ARCH_EXT during initialization then
CHECK_ARCH_EXT before testing each function to see if the processor
being used for testing supports the required instruction set
extensions.

After my refactoring of libm-test infrastructure, the INIT_ARCH_EXT
call is in libm-test-support.c, built only once per floating-point
type.  Now, in fact all definitions of this macro are empty, but given
that the definitions in sysdeps/x86_64/fpu/math-tests-arch.h are
conditional on REQUIRE_* macros defined in particular vector tests, it
seems more correct for the INIT_ARCH_EXT call to go instead in
libm-test-driver.c which gets built separately with those REQUIRE_*
macros properly defined.  This patch moves the call there.

Tested for x86_64 and x86.

1266b9361a Move more csin, csinh tests to auto-libm-test-in. 
When I moved tests of csin and csinh to auto-libm-test-in, I didn't
move a few tests for which gen-auto-libm-tests was very slow because
of MPC slowness on certain inputs.

Now that auto-libm-test-out has been split up, such slowness only
affects regenerating the test expectations for the individual
functions in question, rather than any addition of tests for any
function to auto-libm-test-in.  Thus, I no longer consider it a
problem to have these inputs in auto-libm-test-in, and this patch
moves them there.  This results in test generation for csin and csinh
taking 5m43s (for each of csin and csinh) on my system, while other
functions are unaffected.

I expect the test generation to be much faster in MPC 1.1 (the
relevant performance improvements went in MPC mainline in Dec 2013,
but there hasn't been a release from mainline since then).

Tested for x86_64 and x86.

3789e2fd9d Merge libm-compat-calls-auto and libm-compat-calls 
Both libm-compat-calls and libm-compat-calls-auto list the functions
that must be built for the types float, double, and long double, but
not for other floating-point types that get added to libm.  Besides
that, the use of libm-compat-calls-ldouble-yes to select if
w_lgamma_compatl and k_standardl should be built for long-double (in
libm-compat-calls) has the same effect of the use of type-foreach
(in libm-compat-calls-auto).

This patch merges the contents of libm-compat-calls into
libm-compat-calls-auto, then renames the latter to libm-compat-calls.

Tested for powerpc64le, s390, and x86_64.

9b40563c8b Move -U__LIBC_INTERNAL_MATH_INLINES to test-math-inline.h. 
The libm tests of inline functions undefine __NO_MATH_INLINES (from
math-CPPFLAGS) in test-math-inline.h, but __LIBC_INTERNAL_MATH_INLINES
via -U options in the makefile.

This is an odd inconsistency between the handling of the two macros.
It also depends on the ordering (in compilation commands) of the
various variables providing compiler options (which I think is why
it's using CPPFLAGS-*.c instead of CFLAGS-*.c).

This patch moves the undefine to test-math-inline.h, so improving
consistency and eliminating the dependency on the order in which
variables go in the compilation commands.  The CPPFLAGS-*.c variables
are renamed to CFLAGS-*.c, matching those for the non-inline libm
function tests.

By moving the -U option to the header file, this should ensure that
ordering issues don't arise with a subsequent move of the options to
these tests to target-specific CFLAGS += ... variable settings (for
when tests for each function are build separately and so compilation
options need setting for many more makefile targets, for which
target-specific variable settings seem to be the most convenient form
to generate with iterators).

3b2f60328e Build most libm-test support code once per type. 
libm-test-driver.c contains various functions used in the course of
libm testing, which are built as part of each test using this
machinery.

Currently, these functions get built for three tests for each type
(e.g. test-float, test-ifloat, test-float-finite), plus the vector
function tests.  All these tests are huge and thus slow to build; the
output of gen-libm-test.pl totals around 40 MB across all functions.
To make the individual tests built from the Makefile smaller, it makes
sense to split these tests up so the tests for each function are built
separately (thus, three tests for each (function, type) pair, plus
vector tests built only for functions that actually have vector
versions).  This improves parallelism and means that if tests fail,
the summary of failed tests makes it more obvious where the problem
might be without needing to look in the .out files to see which
functions' tests failed (though architecture maintainers still need to
keep libm-test-ulps up to date to avoid spurious failures of little
interest).

Simply including libm-test-driver.c as-is in such individual-function
tests does not work because of unused static check_* functions (those
functions only being used for the types of the outputs of the function
under test).  It also means the common code gets built over 1000 times
instead of nine (plus vector tests).  To avoid that issue, this patch
splits out the bulk of the libm-test-driver.c code into a separate
file libm-test-support.c (with a few functions made non-static).  That
separate file is built only once for each floating-point type (so at
present three times, or twice on architectures with long double =
double).  Definitions needed in both libm-test-support.c and
libm-test-driver.c go in libm-test-support.h (it's possible some of
those are in fact only needed in one of the two files).
libm-test-driver.c keeps definitions of a limited number of variables
used to configure how libm-test-support.c behaves, various macros and
structures needed by individual-function tests, and the main function.

This move is also consistent in spirit with the move away from
test-skeleton.c having all the test support code, to a small
support/test-driver.c included in individual tests with most of the
code built separately.

12d6284c0e Clean up libm vector tests exception test disabling. 
The libm vector tests disable tests of exception raising via defining
macros EXCEPTION_TESTS_float and EXCEPTION_TESTS_double to 0 in the
headers for individual vector lengths.

As EXCEPTION_TESTS is used in code in libm-test-driver.c that is
otherwise ready to be built only once per type, this is not a good
idea; it's better to define TEST_EXCEPTIONS appropriately so that
flag_test_exceptions then gets initialized appropriately.
Furthermore, it's better to do this just once, in test-math-vector.h,
since there is no actual dependence on the vector length or type.
This patch duly makes that change.

Tested for x86_64.

edbbdb1855 Fix powf inaccuracy (bug 21112). 
Bug 21112 reports a case where powf is substantially inaccurate.  This
results from a multiplication where cp_h*p_h is required to be exact,
and p_h is masked to have only 12 leading nonzero bits in its
mantissa, but the value of cp_h has the 13th bit nonzero, leading to
inexact multiplication results in some cases that can result in large
errors in the final result of powf.  This patch fixes this by using a
value of cp_h correctly rounded to nearest to 12 bits, with a
corresponding updated value of cp_l.

Tested for x86_64 and x86.

dcd4cd5756 Refactor some code in libm-test-driver.c. 
Splitting libm tests by function will mean about a thousand such tests
built separately instead of the present nine (plus vector variants).

When this is done, it's desirable to avoid needing to build all the
test infrastructure so many times.  Also, simply including
libm-test-driver.c as-is into per-function tests doesn't actually
work, because the various check_* functions are not used by all tests
and so generate errors for unused static functions.

Although some pieces of infrastructure depend on the type being tested
while others don't, building once per type seems the simplest
approach.  This patch makes changes to libm-test-driver.c in
preparation for that.  Various cases where functions directly use
macros such as TEST_ERRNO (that may vary depending on things other
than the type under test) are changed to use variables initialized
using those macros, while most of the code in main is moved out to
functions libm_test_init and libm_test_fini.

The idea is that all the functions in libm-test-driver.c will be moved
out in a subsequent patch to be built once per type (and be no longer
static when they are used from per-function tests), while
libm-test-driver.c remains containing definitions of various variables
(no longer static, of course, because they'll be used in the per-type
code) and the main function.  Declarations / macros relevant to both
the once-per-type code and the per-function tests will go in a shared
header.

a622c2db55 Move libm-test TEST_MSG definitions to libm-test-driver.c. 
Various files using the libm-test infrastructure define a TEST_MSG
macro with an informal description of the tests being run.

This patch moves this macro to libm-test-driver.c (the definition
depending on other macros already defined), so files specific to
(type, choice of whether to test inline functions or finite-math-only
functions, vector length) no longer need to define it.  This is in
preparation for replacing files such as test-float.c with per-function
test-float-<func>.c etc. automatically generated in the build
directory when tests are run.

5cbb58493d Split libm-test.inc by function. 
Continuing the process of splitting up libm tests into more reasonably
sized units, this patch splits libm-test.inc into 121 separate
libm-test-<function>.inc files, one per array of test data.  (There
are 126 libm *_test functions, but five of those are for functions
that are aliases for test purposes and so share arrays of test data.)

In the present patch, the 121 files get processed separately by
gen-libm-test.pl, each using only the auto-libm-test-out-<function>
file that is relevant (/dev/null for functions not using
auto-libm-test-* at all).  This effectively eliminates the
serialization on running gen-libm-test.pl.  However, the resulting .c
files still all get #included together, so compiling the limited
number of libm tests using libm-test.inc may still act as a
serialization point (the compilations still all have 40 MB of code to
process).  libm-test.inc doesn't actually have anything in it any more
that needs gen-libm-test.pl processing, but is left as a .inc file
that gets processed to produce a .c file, rather than being renamed,
since the intent of this patch is as an intermediate step before
libm-test.inc gets removed and tests get compiled separately for each
function being tested.

Tested for x86_64.

4f1bc131db Split auto-libm-test-out by function. 
math/auto-libm-test-out is, at over 30 MB, by far the largest file in
the glibc source tree.  This patch splits it by function, so reducing
it to auto-libm-test-out-<func> files that are all under 5 MB in size.

This is preliminary to splitting up libm-test.inc as well so that each
function's tests can also be processed separately by
gen-libm-test.pl.  As a preliminary patch it doesn't actually
implement that step; rather, all the separate files get concatenated
by the Makefile to produce the monolithic auto-libm-test-out file
again as an input to gen-libm-test.pl.  (The concatentation is
identical to the file in the source tree before this patch.)

Even this preliminary step, however, is of use independent of
splitting up libm-test.inc: some tests for csin and csinh have not
been moved to auto-libm-test-in because they result in
auto-libm-test-out generation taking several minutes rather than a few
seconds (all released MPC versions are very slow for certain sin /
sinh inputs; there are some old improvements in MPC mainline which
should eventually become MPC 1.1, but the complex inverse trig and
hyperbolic functions are slow even in MPC mainline and have yet to be
moved to auto-libm-test-in at all), and it seems much more reasonable
to add such inputs to auto-libm-test-in when it will only slow down
regeneration for particular functions than when it will slow down
regeneration globally.

gen-auto-libm-tests still parses the whole input file, but only
generates output for the requested function.  This ensures bad syntax
in the file is always detected, and parsing the whole file is quick;
it's output generation that is comparatively slow for some functions.

Tested for x86_64.
