glibc/include/stdio.h
Zack Weinberg 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.

	* elf/tst-env-setuid-tunables.c: Include config.h with _LIBC
	defined, for HAVE_TUNABLES.
	* inet/tst-checks-posix.c: No need to define _ISOMAC.
	* intl/tst-gettext2.c: Provide own definition of N_.
	* math/test-signgam-finite-c99.c: No need to define _ISOMAC.
	* math/test-signgam-main.c: No need to define _ISOMAC.
	* stdlib/tst-strtod.c: Convert to test-driver. Split locale_test to...
	* stdlib/tst-strtod1i.c: ...this new file.
	* stdlib/tst-strtod5.c: Convert to test-driver and add copyright notice.
        Split tests of __strtod_internal to...
	* 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.
	Don't include init-arch.h.
	* sysdeps/x86_64/multiarch/test-multiarch.h: Include cpu-features.h.
	Don't include init-arch.h.

	* elf/Makefile: Move tst-ptrguard1-static, tst-stackguard1-static,
	tst-tls1-static, tst-tls2-static, tst-tls3-static, loadtest,
	unload, unload2, circleload1, neededtest, neededtest2,
	neededtest3, neededtest4, tst-tls1, tst-tls2, tst-tls3,
	tst-tls6, tst-tls7, tst-tls8, tst-dlmopen2, tst-ptrguard1,
	tst-stackguard1, tst-_dl_addr_inside_object, and all of the
	ifunc tests to tests-internal.
	Don't add $(modules-names) to test-extras.
	* inet/Makefile: Move tst-inet6_scopeid_pton to tests-internal.
	Add tst-deadline to tests-static-internal.
	* malloc/Makefile: Move tst-mallocstate and tst-scratch_buffer to
	tests-internal.
	* misc/Makefile: Move tst-atomic and tst-atomic-long to tests-internal.
	* nptl/Makefile: Move tst-typesizes, tst-rwlock19, tst-sem11,
	tst-sem12, tst-sem13, tst-barrier5, tst-signal7, tst-tls3,
	tst-tls3-malloc, tst-tls5, tst-stackguard1, tst-sem11-static,
	tst-sem12-static, and tst-stackguard1-static to tests-internal.
        Link tests-internal with libpthread also.
	Don't add $(modules-names) to test-extras.
	* nss/Makefile: Move tst-field to tests-internal.
	* posix/Makefile: Move bug-regex5, bug-regex20, bug-regex33,
	tst-rfc3484, tst-rfc3484-2, and tst-rfc3484-3 to tests-internal.
	* stdlib/Makefile: Move tst-strtod1i, tst-strtod3, tst-strtod4,
	tst-strtod5i, tst-tls-atexit, and tst-tls-atexit-nodelete to
	tests-internal.
        * sunrpc/Makefile: Move tst-svc_register to tests-internal.
	* sysdeps/powerpc/Makefile: Move test-get_hwcap and
	test-get_hwcap-static to tests-internal.
	* sysdeps/unix/sysv/linux/Makefile: Move tst-setgetname to
