2017-10-30	Remove _Mlong_double_ etc. macros.	Joseph Myers
	math.h has a macro _Mlong_double_ for the type to use when declaring long double functions, and similar macros for other types. math/Makefile uses -D_Mlong_double_=double in the case of long double having the same ABI as double. This originates with: Mon Jul 8 13:37:40 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * math/math.h (_Mfloat_, _Mlong_double_): New macros, defined iff not already defined to float, long double. Use those macros for _Mdouble_ defns when including mathcalls.h. * math/Makefile [$(long-double-fcts) != yes] (CPPFLAGS): Append -D_Mlong_double_=double. However, math.h stopped declaring long double functions in the case of long double having the same ABI as double (and thus probably stopped actually needing the Makefile definition of _Mlong_double_) with: 1998-11-05 Ulrich Drepper <drepper@cygnus.com> * math/math.h: Unconditionally include bits/mathdef.h. Declare long double functions only if __NO_LONG_DOUBLE_MATH is not defined. * sysdeps/generic/bits/mathdef.h: Define only if __USE_ISOC9X. Define __NO_LONG_DOUBLE_MATH. * sysdeps/m68k/fpu/bits/mathdef.h: Define only if __USE_ISOC9X. * sysdeps/i386/fpu/bits/mathdef.h: Likewise. The declarations were since restored for compiling user code, but remain absent when _LIBC is defined, which is sufficient to avoid problems declaring function aliases of incompatible types. Thus the indirection through the _Mlong_double_ macro is not needed (probably since that 1998 patch), and this patch removes _Mlong_double_ and associated macros for other types, leaving only the macro _Mdouble_ which is actually used as the type for which a given inclusion of <bits/mathcalls.h> should declared functions. Tested for x86_64, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * math/math.h [!_Mfloat_] (_Mfloat_): Do not define.

2017-06-28	Remove NO_LONG_DOUBLE conditionals in libm tests (bug 21607).	Joseph Myers
	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.

2017-05-11	Suppress internal declarations for most of the testsuite.	Zack Weinberg
	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.

Don't include init-arch.h. * sysdeps/x86_64/multiarch/test-multiarch.h: Include cpu-features.h.

2016-01-04	Update copyright dates with scripts/update-copyrights.	Joseph Myers

2015-11-16	Work around conflicting declarations of math functions	Florian Weimer
	This restores compilation on architectures such as armhfp which alias acos and acosl because double and long double are the same.
2015-11-06	Fix typo in signgam test messages.	Joseph Myers
	I noticed a typo in the messages from the signgam tests I recently added. This patch fixes it. Tested for x86_64 and x86. * math/test-signgam-finite.c (RUN_TESTS): Correct messages about calls with argument -0.5. * math/test-signgam-finite-c99.c (RUN_TESTS): Likewise.
2015-11-05	Fix finite-math-only lgamma functions signgam setting (bug 19211).	Joseph Myers
	The lgamma inline functions in bits/math-finite.h do not set signgam if __USE_ISOC99, even when other feature test macros mean a standard such as XSI POSIX is selected for which it should be set. (This is essentially the opposite issue to bug 15421, the out-of-line versions setting signgam even when they shouldn't.) This patch fixes those functions to use __USE_MISC \|\| __USE_XOPEN as the condition for when to set signgam, since it's the condition for when math.h declares signgam. The legacy gamma* names are only declared at all if __USE_MISC \|\| __USE_XOPEN, so they just set signgam unconditionally. Tests for certain standards or not using _GNU_SOURCE cannot use test-skeleton.c (this is a known issue noted on the wiki todo list). Thus, the new tests that signgam remains not set in ISO C modes do not use test-skeleton.c. They also define _ISOMAC to avoid running into declarations in the internal include/ headers that only work in _GNU_SOURCE mode. Tested for x86_64 and x86. [BZ #19211] * math/bits/math-finite.h (lgamma): Set signgam if [__USE_MISC \|\| __USE_XOPEN], not if [!__USE_ISOC99]. (lgammaf): Likewise. (lgammal): Likewise.
