2017-08-03Consistently use uintN_t not u_intN_t in libm.Joseph Myers
This patch changes libm code to make consistent use of C99 uintN_t types instead of sometimes using those and sometimes using the older nonstandard u_intN_t names. This makes sense as a cleanup in its own right, and also facilitates merges to GCC's libquadmath (which gets the types from stdint.h and so may not have u_intN_t available at all). Tested for x86_64, and with build-many-glibcs.py. * math/s_nextafter.c (__nextafter): Use uintN_t instead of u_intN_t. * math/s_nexttowardf.c (__nexttowardf): Likewise. * sysdeps/generic/math_private.h (ieee_double_shape_type): Likewise.

2017-08-02Fix tgmath.h for __int128 (bug 21686).Joseph Myers
When a tgmath.h macro is passed a double argument and an argument of type __int128, it generates a call to a long double function (although the result still gets converted to type double). __int128 is similar enough to integer types that it should be handled consistently like them, so always like double for these macros rather than sometimes like double and sometimes like long double. This patch fixes the logic accordingly and makes gen-tgmath-tests.py generate tests for __int128. Tested for x86_64 and x86. [BZ #21686] * math/tgmath.h (__TGMATH_BINARY_REAL_ONLY): Add arguments before comparing size with that of double. (__TGMATH_BINARY_REAL_STD_ONLY): Likewise. (__TGMATH_BINARY_REAL_RET_ONLY): Likewise.

2017-08-02Fix tgmath.h for bit-fields (bug 21685).Joseph Myers
The tgmath.h macros produce errors for bit-field arguments, because they apply sizeof and typeof to the arguments. This patch fixes them to use unary + systematically before using sizeof or typeof on arguments that might be bit-fields (note that __real__ of a bit-field is still a bit-field for this purpose, since it's an lvalue). gen-tgmath-tests.py is extended to add tests for this case. Tested for x86_64. [BZ #21685] * math/tgmath.h (__tgmath_real_type): Use unary + on potentially bit-field expressions passed to sizeof or typeof.

2017-06-28Support _Float128 in tgmath.h.Joseph Myers
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. (__TGMATH_CF128): Likewise.

2017-06-28Use clog10 not __clog10 in tgmath.h log10 macro.Joseph Myers
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.
2017-06-28Fix tgmath.h totalorder, totalordermag return type (bug 21687).Joseph Myers
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. [BZ #21687] * math/tgmath.h (__TGMATH_BINARY_REAL_RET_ONLY): New macro. (totalorder): Use it. (totalordermag): Likewise. * math/gen-tgmath-tests.py (Tests.add_all_tests): Enable tests of totalorder and totalordermag. * math/test-tgmath.c (F(compile_test)): Do not call totalorder or totalordermag in arguments of calls to those functions. (NCALLS): Change to 134.
2017-06-28Simplify tgmath.h for integer return types.Joseph Myers
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. * math/tgmath.h (__TGMATH_UNARY_REAL_RET_ONLY): Do not take or cast to return type argument. (__TGMATH_TERNARY_FIRST_REAL_RET_ONLY): Likewise.

2017-06-28Remove 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. [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>.

2017-06-28Add more thorough generated tgmath.h test.Joseph Myers
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. * math/Makefile [PYTHON] (tests): Add test-tgmath3.

2017-06-26Add float128 support for ia64.Joseph Myers
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. * sysdeps/ia64/bits/floatn.h: New file. * sysdeps/ia64/float128-abi.h: Likewise. * manual/math.texi (Mathematics): Document support for _Float128 on ia64. * sysdeps/ia64/Makefile [$(subdir) = math] (CPPFLAGS): Append to Makefile variable. * sysdeps/ia64/fpu/e_sqrtf128.c: New file. * sysdeps/ia64/fpu/k_rem_pio2.c: Remove file. * sysdeps/ia64/fpu/sfp-machine.h: New file.

2017-06-26Add float128 support for x86_64, x86.Joseph Myers
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.) * sysdeps/i386/Implies: Add ieee754/float128. * sysdeps/x86_64/Implies: Likewise. * sysdeps/x86/bits/floatn.h: New file. * sysdeps/x86/float128-abi.h: Likewise. * manual/math.texi (Mathematics): Document support for _Float128 on x86_64 and x86. * sysdeps/i386/fpu/fenv_private.h: Include <bits/floatn.h>.

2017-06-23Make libm-test-support code clear exceptions after each test.Joseph Myers
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). * libm-test-support.c (check_float_internal): Clear exceptions at end of function. (check_int): Likewise. (check_long): Likewise.

2017-06-22Make errno-setting libm templates include errno.h.Joseph Myers
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.

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. * math/Makefile (libm-calls): Move e_exp2F to gen-libm-calls.

2017-05-11Suppress 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.

2017-03-31Fix condition for inclusion of math-finite.h for long doubleGabriel F. T. Gomes
The condition for declaration of long double functions in math-finite.h was #ifdef __MATH_DECLARE_LDOUBLE before the macroization of this file. After the macroization, it was incorreclty changed to #if __MATH_DECLARE_LDOUBLE, which broke the build for arm. * math/math.h: Fix check for __MATH_DECLARE_LDOUBLE. * math/bits/math-finite.h: Likewise.

2017-03-16Remove C++ namespace handling from glibc headers.Joseph Myers
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). * misc/sys/cdefs.h (__BEGIN_NAMESPACE_STD): Remove macro.

2017-03-15Improve float range reduction accuracy near pi/2 (bug 21094).Joseph Myers
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). [BZ #21094] * sysdeps/ieee754/flt-32/e_rem_pio2f.c (__ieee754_rem_pio2f): Use 24+24+24-bit pi for wider range of values around pi/2. * math/auto-libm-test-in: Add more tests of cos and tan. * math/auto-libm-test-out-cos: Regenerated. * math/auto-libm-test-out-tan: Likewise.
2017-03-15Split helper classification macros from mathcalls.hGabriel F. T. Gomes
The classification macros: finite, fpclassify, iseqsig, isinf, isnan, 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.

2017-03-10Update auto-libm-test-out for catan / catanh.Stefan Liebler
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.

2017-03-01Miscellaneous low-risk changes preparing for _ISOMAC testsuite.Zack Weinberg
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.

2017-02-24Run libm tests separately for each function.Joseph Myers
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.

Each of auto-libm-test-out-catan and auto-libm-test-out-catanh takes about three seconds to generate on my system (so in fact it wasn't necessary after all to defer the move to auto-libm-test-* until the output files were split up by function).

2017-02-14Move INIT_ARCH_EXT call from libm-test-support to libm-test-driver.Joseph Myers
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. * math/libm-test-support.h: Do not include <math-tests-arch.h> here. * math/libm-test-support.c (libm_test_init): Do not call INIT_ARCH_EXT here. * math/libm-test-driver.c: Include <math-tests-arch.h>. (main): Call INIT_ARCH_EXT.
2017-02-09Move more csin, csinh tests to auto-libm-test-in.Joseph Myers
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. * math/auto-libm-test-in: Add more tests of csin and csinh. * math/auto-libm-test-out-csin: Regenerated. * math/auto-libm-test-out-csinh: Likewise. * math/libm-test-csin.inc (csin_test_data): Remove tests moved to auto-libm-test-in. * math/libm-test-csinh.inc (csinh_test_data): Likewise.
2017-02-09Merge libm-compat-calls-auto and libm-compat-callsGabriel F. T. Gomes
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. * math/Makefile (libm-compat-calls-ldouble-yes): Merge into libm-compat-calls-auto. (libm-compat-calls): Likewise. (libm-compat-calls-auto): Rename to libm-compat-calls and add w_lgamma_compatF and k_standardF (merged from the items above). (libm-routines): Use libm-compat-calls, instead of libm-compat-calls-auto, with type-foreach.
2017-02-09Move -U__LIBC_INTERNAL_MATH_INLINES to test-math-inline.h.Joseph Myers
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). Tested for x86_64. * math/test-math-inline.h (__LIBC_INTERNAL_MATH_INLINES): Undefine macro. * math/Makefile (CPPFLAGS-test-ifloat.c): Rename to ... (CFLAGS-test-ifloat.c): ... this.

2017-02-08Build most libm-test support code once per type.Joseph Myers
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.

2017-02-07Clean up libm vector tests exception test disabling.Joseph Myers
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. * math/test-math-finite.h (TEST_EXCEPTIONS): New macro. * math/test-math-no-finite.h (TEST_EXCEPTIONS): Likewise. * math/test-math-vector.h (TEST_EXCEPTIONS): Likewise. * math/test-math-no-inline.h (TEST_EXCEPTIONS): Remove macro. * math/test-double-vlen2.h (EXCEPTION_TESTS_double): Likewise. * math/test-double-vlen4.h (EXCEPTION_TESTS_double): Likewise. * math/test-double-vlen8.h (EXCEPTION_TESTS_double): Likewise. * math/test-float-vlen4.h (EXCEPTION_TESTS_float): Likewise. * math/test-float-vlen8.h (EXCEPTION_TESTS_float): Likewise. * math/test-float-vlen16.h (EXCEPTION_TESTS_float): Likewise.
2017-02-07Fix powf inaccuracy (bug 21112).Joseph Myers
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. [BZ #21112] * sysdeps/ieee754/flt-32/e_powf.c (cp_h): Use value with trailing 12 bits zero. (cp_l): Update for new value of cp_h. * math/auto-libm-test-in: Add another test of pow. * math/auto-libm-test-out-pow: Regenerated.
2017-02-06Refactor some code in libm-test-driver.c.Joseph Myers
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. Tested for x86_64. * math/libm-test-driver.c (flag_test_errno): New variable. (flag_test_exceptions): Likewise. (flag_test_finite): Likewise. (flag_test_inline): Likewise. (flag_test_mathvec): Likewise. (test_msg): Likewise. (ulp_idx): Likewise. (qtype_str): Likewise.

(test_exceptions): Use flag_test_exceptions not TEST_EXCEPTIONS. (test_errno): Use flag_test_errno not TEST_ERRNO. (enable_test): Use flag_test_inline, flag_test_finite and flag_test_mathvec instead of TEST_INLINE, TEST_FINITE and TEST_MATHVEC. (libm_test_init): New function. Factored out of main. (libm_test_finish): Likewise. (main): Call libm_test_init and libm_test_finish and move most code to those functions.
