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. [BZ #21607] * math/basic-test.c [!NO_LONG_DOUBLE]: Change conditionals to [LDBL_MANT_DIG > DBL_MANT_DIG]. * math/bug-nextafter.c [!NO_LONG_DOUBLE]: Remove conditionals. * math/bug-nexttoward.c [!NO_LONG_DOUBLE]: Likewise. * math/test-math-isinff.cc [!NO_LONG_DOUBLE]: Likewise. * math/test-math-iszero.cc [!NO_LONG_DOUBLE]: Likewise. * math/test-nan-overflow.c [!NO_LONG_DOUBLE]: Likewise. * math/test-nan-payload.c [!NO_LONG_DOUBLE]: Likewise. * math/test-nearbyint-except-2.c [!NO_LONG_DOUBLE]: Likewise. * math/test-nearbyint-except.c [!NO_LONG_DOUBLE]: Likewise. * math/test-powl.c [!NO_LONG_DOUBLE]: Likewise. * math/test-signgam-finite-c99.c [!NO_LONG_DOUBLE]: Likewise. * math/test-signgam-finite.c [!NO_LONG_DOUBLE]: Likewise. * math/test-signgam-main.c [!NO_LONG_DOUBLE]: Likewise. * math/test-snan.c [!NO_LONG_DOUBLE]: Likewise. * math/test-tgmath-ret.c [!NO_LONG_DOUBLE]: Likewise. * math/test-tgmath.c: Include <float.h>.

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

Fix lgamma setting signgam for ISO C (bug 15421).
The lgamma (and likewise lgammaf, lgammal) function wrongly sets the signgam variable even when building for strict ISO C conformance (-std=c99 / -std=c11), although the user may define such a variable and it's only in the implementation namespace for POSIX with XSI extensions enabled. Following discussions starting at <https://sourceware.org/ml/libc-alpha/2013-04/msg00767.html> and <https://sourceware.org/ml/libc-alpha/2015-10/msg00844.html>, it seems that the safest approach for fixing this particular issue is for signgam to become a weak alias for a newly exported symbol __signgam, with the library functions only setting __signgam, at which point static linker magic will preserve the alias for newly linked binaries that refer to the library's signgam rather than defining their own, while breaking the alias for programs that define their own signgam, with new symbol versions for lgamma functions and with compat symbols for existing binaries that set both signgam and __signgam. This patch implements that approach for the fix. signgam is made into a weak alias. The four symbols __signgam, lgamma, lgammaf, lgammal get new symbol versions at version GLIBC_2.23, with the existing versions of lgamma, lgammaf and lgammal becoming compat symbols. When the compat versions are built, gamma, gammaf and gammal are aliases for the compat versions (i.e. always set signgam); this is OK as they are not ISO C functions, and avoids adding new symbol versions for them unnecessarily. When the compat versions are not built (i.e. for static linking and for future glibc ports), gamma, gammaf and gammal are aliases for the new versions that set __signgam. The ldbl-opt versions are updated accordingly. The lgamma wrappers are adjusted so that the same source files, included from different files with different definitions of USE_AS_COMPAT, can build either the new versions or the compat versions. Similar changes are made to the ia64 versions (untested). Tests are added that the lgamma functions do not interfere with a user variable called signgam for ISO C, with various choices for the size of that variable, whether it is initialized, and for static and dynamic linking. The conformtest whitelist entry is removed as well. Tested for x86_64, x86, mips64 and powerpc, including looking at objdump --dynamic-syms output to make sure the expected sets of symbols were aliases. Also spot-tested that a binary built with old glibc works properly (i.e. gets signgam set) when run with new glibc. [BZ #15421] * sysdeps/ieee754/s_signgam.c (signgam): Rename to __signgam, initialize with 0 and define as weak alias of __signgam. * include/math.h [!_ISOMAC] (__signgam): Declare. * math/Makefile (libm-calls): Add w_lgamma_compat.
