Do not use __builtin_types_compatible_p in C++ mode (bug 21930)
The logic to define isinf for float128 depends on the availability of __builtin_types_compatible_p, which is only available in C mode, however, the conditionals do not check for C or C++ mode. This lead to an error in libstdc++ configure, as reported by bug 21930. This patch adds a conditional for C mode in the definition of isinf for float128. No definition is provided in C++ mode, since libstdc++ headers undefine isinf. Tested for powerpc64le (glibc test suite and libstdc++-v3 configure). [BZ #21930] * math/math.h (isinf): Check if in C or C++ mode before using __builtin_types_compatible_p, since this is a C mode feature. |

Consistently use uintN_t not u_intN_t in libm.
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.

Fix tgmath.h for __int128 (bug 21686).
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.

Fix tgmath.h for bit-fields (bug 21685).
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.

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.

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. |

Simplify tgmath.h for integer return types.
The tgmath.h macros for function with integer return types generate unnecessary casts to the return type.

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.

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. * math/Makefile [PYTHON] (tests): Add test-tgmath3. [PYTHON] (generated): Add test-tgmath3.c. [PYTHON] (CFLAGS-test-tgmath3.c): New variable. [PYTHON] ($(objpfx)test-tgmath3.c): New rule. |

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. * 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.

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.) * 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>.

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). * libm-test-support.c (check_float_internal): Clear exceptions at end of function. (check_int): Likewise. (check_long): Likewise.

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.

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).

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

Macroize inclusion of math-finite.h
This patch macroizes the declarations in math/bits/math-finite.h similarly to what math/bits/mathcalls.h does. For each floating-point type, the file is included once in math/math.h. This will reduce the amount of repetitive boilerplate required when adding float128 versions of these declarations. Tested for powerpc64le and s390x. * math/math.h: Include bits/math-finite.h once per floating-point type. * math/bits/math-finite.h: Macroize all declarations by floating-point type. |

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). * misc/sys/cdefs.h (__BEGIN_NAMESPACE_STD): Remove macro.

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). [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. |

Split helper classification macros from mathcalls.h
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. |

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.

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.

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. * 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>.

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. * 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. |

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. * math/Makefile (libm-compat-calls-ldouble-yes): Merge into libm-compat-calls-auto. (libm-compat-calls): Likewise.

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). 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.

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.

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. * 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. |

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. [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. |

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. Tested for x86_64. * math/libm-test-driver.c (flag_test_errno): New variable.

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. Tested for x86_64. * math/libm-test-driver.c (STRX): New macro. (STR): Likewise. (STR_FLOAT): Likewise. (STR_VEC_LEN): Likewise. (TEST_MSG): Likewise.

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. * math/libm-test.inc: Move all tests of individual functions to libm-test-*.inc and #include libm-test-*.c files. (acos_test_data): Remove. (acos_test): Likewise.

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.

Eliminate libm-test.stmp.
math/Makefile uses libm-test.stmp to handle dependencies involving multiple generated files all generated by a single sequence of commands in a single Makefile rule. Having separated the libm-test-ulps.h and libm-test.c generation into separate runs of gen-libm-test.pl, there is now no need for a single rule to generate multiple target files; each of the three target files involved can be generated by a separate Makefile rule, meaning normal dependencies on the individual files can be used and so libm-test.stmp is not needed at all. This patch does just that, eliminating the .stmp file, in further preparation for when there are many separate libm-test-<func>.c files generated from libm-test-<func>.inc and the dependencies are on just the relevant .c file in each case. Tested for x86_64. * math/Makefile (generated): Do not include libm-test.stmp. ($(addprefix $(objpfx), $(libm-tests-generated))): Do not depend on $(objpfx)libm-test.stmp.

Rework gen-libm-test.pl input/output handling.
This patch reworks how input and output files are specified for gen-libm-test.pl. Previously, the script had names of various inputs and outputs hardcoded, with a -o option to specify an output directory. This patch replaces this with all inputs and outputs being specified explicitly as the arguments of options passed to the script. Outputs are only generated if the relevant option is passed, and only the processing required for the indicated outputs is done. The Makefile is made to pass options for generating libm-test-ulps.h in a separate invocation of gen-libm-test.pl from that generating libm-test.c. This is all in preparation for splitting up libm-test.inc and auto-libm-test-out and running tests separately for each function, when gen-libm-test.pl will be run separately for each function to generate the .c file but only once to generate libm-test-ulps.h (and those runs will be able to be in parallel). Tested for x86_64. The generated libm-test.c and libm-test-ulps.h are identical before and after the patch. Also tested the "make regen-ulps" case. * math/gen-libm-test.pl ($output_dir): Remove variable. ($srcdir): Likewise. ($opt_a): New variable. ($opt_c): Likewise. ($opt_C): Likewise.

Move non-function-specific parts of libm-test.inc to separate file.
libm-test.inc contains both test infrastructure and tests of individual functions. This patch moves the infrastructure to a separate file libm-test-driver.c. This is in preparation for splitting the tests of individual functions into separate source files, which will be processed individually by gen-libm-test.pl (so e.g. libm-test-acos.inc and auto-libm-test-out-acos will be processed by gen-libm-test.pl to produce libm-test-acos.c, and files such as test-double-acos.c will be generated by the Makefile to include appropriate headers, libm-test-driver.c and libm-test-acos.c so tests of each function get run separately). It is no doubt possible to split things up further, so that functions not depending on the type being tested only get compiled once and most of those depending on the type being tested get compiled once per type (rather than separately for variants such as inline / no-inline, and separately for each function being tested after that split), but this rearrangement as-is seems a useful incremental step towards splitting these tests by function. * math/libm-test-driver.c: New file.

Remove libm-test.inc comment listing functions tested and not tested.
math/libm-test.inc has a comment listing the functions tested and not tested. The list of functions tested duplicates what is immediately obvious from the rest of the file and adds another place to update when adding a function. I've put the information about functions not tested on the wiki todo list; this patch removes that comment, in preparation for splitting tests of each function into separate .inc files with common code staying in a separate .c file. Tested for x86_64. * math/libm-test.inc: Remove comment listing functions tested and not tested. |

Remove before-compile setting in math/Makefile.
In <https://sourceware.org/ml/libc-alpha/2015-12/msg00543.html>, Florian noted highly parallel builds being slowed down by gen-libm-test.pl running during the build, when it should only run for testing, not for building glibc itself. This is a consequence of libm-test.c being listed in before-compile. That listing in before-compile arose from the error reported in <https://sourceware.org/ml/libc-hacker/1999-10/msg00054.html> when building dependencies: at that time, dependencies were generated separation from compilation, so if a source file included a generated file it wasn't enough for the dependencies for the .o file to be correct, the generated file needed to be listed in before-compile. Since <https://sourceware.org/ml/libc-hacker/2003-05/msg00001.html>, dependencies are generated as a side-effect of compilation. This means that having the right dependencies for the .o files for the tests fully suffices to ensure that libm-test.c is generated by the time it's needed; no entry in before-compile is needed. And we indeed have such a dependency for all the tests using libm-test.c: $(addprefix $(objpfx), $(libm-tests.o)): $(objpfx)libm-test.stmp Thus, the before-compile definition is unnecessary, and this patch removes it. (This may of course move serialization from the glibc build to glibc testing, but I intend to split up libm-test.inc so that tests for each (floating-point type, libm function) pair are built and run separately, which should reduce that serialization.) Tested for x86_64. * math/Makefile (before-compile): Remove. |

fetestexceptflag (const fexcept_t *flagp, int excepts)
{
/* Most versions of fegetexceptflag store exceptions in a form such
that this works. */
return *flagp & excepts & FE_ALL_EXCEPT;
}
In the case where FE_ALL_EXCEPT is nonzero but exceptions may not be
supported at runtime, this only works if fegetexceptflag cleared all
the bits of FE_ALL_EXCEPT in *flagp; otherwise it accesses
uninitialized data. This showed up as a failure of
math/test-fetestexceptflag for MIPS o32 soft-float. This patch makes
the fallback fegetexceptflag store 0 (fexcept_t is an integer type
everywhere) so that this works. (No bug report in Bugzilla because
this wasn't user-visible - at least, without using tools to detect
uninitialized memory use at runtime - without fetestexceptflag, which
is new in 2.25.)
Tested for MIPS o32 soft-float.
* math/fgetexcptflg.c (__fegetexceptflag): Store 0 in fexcept_t
object.

XFAIL libm-test.inc tests as needed for ibm128.
This patch arranges for various libm-test.inc tests to be XFAILed for ibm128-libgcc in non-default rounding modes. The tests are marked with XFAIL_ROUNDING_IBM128_LIBGCC and gen-libm-test.pl is made to transform that to XFAIL_IBM128_LIBGCC or 0 depending on the rounding mode. This should allow test-ldouble, test-ildouble and test-ldouble-finite to pass with unmodified libgcc, given an ulps regeneration. (The case of patched libgcc was already clean up to ulps and possibly hypot cases very close to the overflow threshold that may need more XFAILing; patched libgcc, which should work with TEST_COND_ibm128_libgcc defined to 0 to disable all these XFAILs, does need slightly different ulps from unpatched.) Note that soft-float powerpc will still fail because of <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64811> resulting in spurious "invalid" exceptions in the libgcc code (for hard float, <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58684> hides that bug). Tested for powerpc. * math/libm-test.inc (XFAIL_IBM128_LIBGCC): New macro. (fdim_test_data): Use XFAIL_ROUNDING_IBM128_LIBGCC for some tests. (fma_test_data): Likewise. (hypot_test_data): Likewise.

Improve libm-test XFAILing for ibm128-libgcc.
This patch further improves XFAILing for ibm128-libgcc of tests in auto-libm-test-*. The bulk of the cases needing XFAILing are xfail-rounding:ibm128-libgcc used for inputs where (possibly after rounding the inputs to another floating-point type) the result overflows (and the result in non-default rounding modes may be wildly wrong with unpatched libgcc) or underflows near 0 (and the result in non-default rounding modes may end up having the wrong sign). This patch makes gen-auto-libm-tests detect such cases and apply xfail-rounding:ibm128-libgcc automatically to them, so most of the manual XFAILs in auto-libm-test-in are no longer needed (some are still needed if e.g. the result is very close to overflow, resulting in an internal overflow in libgcc in some rounding modes). A few manual XFAILs are added for cases not covered by this gen-auto-libm-tests change, and a few existing such XFAILs are left in. Tested for powerpc. * math/gen-auto-libm-tests.c (output_for_one_input_case): Apply xfail-rounding:ibm128-libgcc automatically to tests overflowing and those that can underflow to zero. * math/auto-libm-test-in: Remove most XFAILs for ibm128-libgcc and add others. * math/auto-libm-test-out: Regenerated. |

Make fallback fesetexceptflag always succeed (bug 21028).
The fallback implementation of fesetexceptflag currently fails if any exceptions are specified. It should always succeed, because the exception state is always that all exceptions (if any are defined in <fenv.h> but not supported in this configuration) are always clear, just as fallback fetestexcept always succeeds and fallback fesetenv always succeeds unless asked to set FE_NOMASK_ENV. This patch fixes it accordingly. Together with the patch to test-fexcept.c to allow feraiseexcept to fail in another place, this stops that test from failing for MIPS soft-float. Tested for mips64 soft-float. [BZ #21028] * math/fsetexcptflg.c (__fesetexceptflag): Always return 0. * math/test-fexcept.c (test_set): Allow failure of feraiseexcept if EXCEPTION_TESTS returns false. |

Update libm-test XFAILs for ibm128 format.
This patch cleans up and updates the libm-test XFAILs for the ibm128 format. More of them are changed to use a new ibm128-libgcc conditional, to reflect that they are not in fact needed if you've patched libgcc to fix the known issues (at substantial performance cost). Many additional XFAILs are added for tests that fail with unpatched libgcc (most but not all of them xfail-rounding). Note that further such fixes will be needed for test-ldouble actually to pass with default libgcc (in particular, XFAILs for pow tests and for various affected tests directly embedded in libm-test.inc). With patched libgcc, there may be a few XFAILs needed but the results are already substantially clean apart from a few ulps differences. Tested for powerpc. * math/libm-test.inc (TEST_COND_ibm128_libgcc): New macro. (init_max_error) [TEST_COND_ibm128]: Increase maximum error allowed to 16 ulps. * math/auto-libm-test-in: Change most XFAILs for ibm128 to use ibm128-libgcc. XFAIL more tests for ibm128-libgcc. * math/auto-libm-test-out: Regenerated. |

Move wrappers to libm-compat-calls-auto
This commit moves one step towards the deprecation of wrappers that use _LIB_VERSION / matherr / __kernel_standard functionality, by adding the suffix '_compat' to their filenames and adjusting Makefiles and #includes accordingly. New template wrappers that do not use such functionality will be added by future patches and will be first used by the float128 wrappers. |

Fix math/test-fenvinline for no-exceptions configurations.
This patch fixes math/test-fenvinline.c to stop it failing in no-exceptions configurations (where some exception macros are defined but may not be supported at runtime). The relevant parts of the test are disabled in that case; some parts can still run (and the rounding mode tests are written in a way such that they work even if the rounding modes aren't supported). Tested for mips64 soft-float, and for x86_64 to make sure the tests still run when the exceptions are supported. * math/test-fenvinline.c (do_test): Disable tests of raised exceptions if !EXCEPTION_TESTS (FLOAT). |

Fix math/test-nearbyint-except for no-exceptions configurations.
The test math/test-nearbyint-except conditions some of its tests on an EXCEPTION_TESTS call, not not all that need such a condition. This patch fixes it to use such a conditional for all its tests and to return 77 (UNSUPPORTED) if none of the floating-point types tested support exceptions. Tested for mips64 soft float (where the test previously failed and is now UNSUPPORTED); also tested for x86_64 to make sure the test still PASSes in exceptions-supported cases. * math/test-nearbyint-except.c: Include <stdbool.h>. (any_supported): New variable. (TEST_FUNC): Return early if !EXCEPTION_TESTS (FLOAT). Otherwise set any_supported. (do_test): Return 77 if no floating-point type supported exceptions. |

Add fromfp functions.
TS 18661-1 defines fromfp functions (fromfp, fromfpx, ufromfp, ufromfpx, and float and long double variants) to convert from floating-point to an integer type with any signedness and any given width up to that of intmax_t, in any of the five IEEE rounding modes (the usual four for binary floating point, plus rounding to nearest with ties rounding away from zero), with control of whether in-range non-integer values should result in the "inexact" exception being raised. This patch implements these functions for glibc. These implementations are (apart from raising exceptions) pure integer implementations; it's entirely possible optimized versions could be devised for some architectures. A common math/fromfp.h header provides various common helper code that can readily be shared between the implementations for different types. For each type, the bulk of the implementation is also shared between the four functions, with wrappers that define UNSIGNED and INEXACT macros appropriately before including the main implementation. As the functions return intmax_t and uintmax_t without math.h being allowed to expose those typedef names, they are declared using __intmax_t and __uintmax_t as obtained from <bits/types.h>. The FP_INT_* rounding direction macros are defined as ascending integers in the order the names are listed in the TS; I see no significant value in allowing architectures to vary the values of them. The libm-test machinery is duly adapted to handle unsigned int arguments, and intmax_t and uintmax_t results. Because each test input is generally tested for four functions, five rounding modes and several different widths, the libm-test.inc additions are very large. Thus, the diffs in the body of this message exclude the libm-test.inc changes, with the full patch being attached gzipped. The bulk of the new tests were generated (expanded from a test input plus rounding results and information about where it lies in the relevant interval between integers, to libm-test tests for all relevant combinations of function, rounding direction and width) by a script that's included in the patch as math/gen-fromfp-tests.py (input data math/gen-fromfp-tests-inputs); as an ad hoc script that's not really expected to be rerun, it's not very polished, but it's at least plausibly useful for adding any further tests for these functions in future. I may split the libm-test tests up by function in future (so both libm-test.inc and auto-libm-test-out are split into separate files, and the tests for each function are also built and run separately), but not for 2.25. For no obvious reason, adding tgmath tests for the new functions resulted in -Wuninitialized errors from test-tgmath.c about the variable i being used uninitialized. Those errors were correct - the variable is read by the frexp version in test-tgmath.c (where real frexp would write through that pointer instead of reading it) - but I don't know why this patch would result in the pre-existing issue being newly detected. The patch initializes the variable to avoid those errors. With these changes, glibc 2.25 should have all the library features from TS 18661-1 other than the functions that round result to narrower type (and constant rounding directions, but I'm considering those mainly a compiler feature not a library one).

Add roundeven, roundevenf, roundevenl.
TS 18661-1 defines roundeven functions that round a floating-point number to the nearest integer, in that floating-point type, with ties rounding to even (whereas the round functions round ties away from zero). As with other such functions, they raise no exceptions apart from "invalid" for signaling NaNs. There was a previous user request for this functionality in glibc in <https://sourceware.org/ml/libc-help/2015-02/msg00005.html>. This patch implements these functions for glibc. The implementations use integer bit-manipulation (or roundeven on the high and low parts, in the IBM long double case). It's possible that there may be faster approaches on some architectures (in particular, on AArch64 the frintn instruction should do exactly what's required); I'll leave it to architecture maintainers or others interested to implement such architecture-specific versions if desired. (Where architectures have instructions to round to nearest integer in the current rounding mode, implementations saving and restoring the rounding mode - and dealing with exceptions if those instructions generate "inexact" - are also possible, though their performance depends on the cost of manipulating exceptions / rounding mode state.)

Define FE_SNANS_ALWAYS_SIGNAL.
TS 18661-1 defines a macro FE_SNANS_ALWAYS_SIGNAL in <fenv.h>, to indicate that the recommended practice regarding sNaNs (that operations always produce a qNaN output with "invalid" exception, even in the fmax / fmin / hypot / pow cases where a qNaN input would not result in qNaN output) is followed. Now that those functions with C99 special cases for NaNs have been fixed not to apply those special cases to sNaN, only to qNaN, glibc follows that recommended practice. This patch makes it define the corresponding macro. Since compiler optimizations may affect whether sNaNs behave as expected and the macro relates to both language and library features, it is only defined if __SUPPORT_SNAN__ is defined (which GCC defines for -fsignaling-nans). It is also not defined if FE_INVALID is undefined, since the recommended practice specifically refers to raising the "invalid" exception, so it seems inappropriate to define the macro for soft-float cases without support for exceptions. (Further refinement would be possible in cases where bits/fenv.h is shared by configurations both with and without exceptions support.) Tested for x86_64 and x86, and also did compile-only testing for nios2 to cover the no-exceptions case. * math/fenv.h [__GLIBC_USE (IEC_60559_BFP_EXT) && FE_INVALID && __SUPPORT_SNAN__] (FE_SNANS_ALWAYS_SIGNAL): New macro. * math/test-fe-snans-always-signal.c: New file. * math/Makefile (tests): Add test-fe-snans-always-signal.

Fix x86, x86_64 fmax, fmin sNaN handling, add tests (bug 20947).
Various fmax and fmin function implementations mishandle sNaN arguments: (a) When both arguments are NaNs, the return value should be a qNaN, but sometimes it is an sNaN if at least one argument is an sNaN. (b) Under TS 18661-1 semantics, if either argument is an sNaN then the result should be a qNaN (whereas if one argument is a qNaN and the other is not a NaN, the result should be the non-NaN argument). Various implementations treat sNaNs like qNaNs here. This patch fixes the x86 and x86_64 versions (ignoring float and double for 32-bit x86 given the inability to reliably avoid the sNaN turning into a qNaN before it gets to the called function). Tests of sNaN inputs to these functions are added. Note on architecture versions I haven't changed for this issue: AArch64 already gets this right (it uses a hardware instruction with the correct semantics for both quiet and signaling NaNs) and does not need changes. It's possible Alpha, IA64, SPARC might need changes (this would be shown by the testsuite if so). Tested for x86_64 and x86 (both i686 and i586 builds, to cover the different x86 implementations).

Refactor long double information into bits/long-double.h.
Information about whether the ABI of long double is the same as that of double is split between bits/mathdef.h and bits/wordsize.h. When the ABIs are the same, bits/mathdef.h defines __NO_LONG_DOUBLE_MATH. In addition, in the case where the same glibc binary supports both -mlong-double-64 and -mlong-double-128, bits/wordsize.h defines __LONG_DOUBLE_MATH_OPTIONAL, along with __NO_LONG_DOUBLE_MATH if this particular compilation is with -mlong-double-64. As part of the refactoring I proposed in <https://sourceware.org/ml/libc-alpha/2016-11/msg00745.html>, this patch puts all that information in a single header, bits/long-double.h. It is included from sys/cdefs.h alongside the include of bits/wordsize.h, so other headers generally do not need to include bits/long-double.h directly. Previously, various bits/mathdef.h headers and bits/wordsize.h headers had this long double information (including implicitly in some bits/mathdef.h headers through not having the defines present in the default version). After the patch, it's all in six bits/long-double.h headers. Furthermore, most of those new headers are not architecture-specific. Architectures with optional long double all use the ldbl-opt sysdeps directory, either in the order (ldbl-64-128, ldbl-opt, ldbl-128) or (ldbl-128ibm, ldbl-opt). Thus a generic header for the case where long double = double, and headers in ldbl-128, ldbl-96 and ldbl-opt, suffices to cover every architecture except for cases where long double properties vary between different ABIs sharing a set of installed headers; fortunately all the ldbl-opt cases share a single compiler-predefined macro __LONG_DOUBLE_128__ that can be used to tell whether this compilation is -mlong-double-64 or -mlong-double-128. The two cases where a set of headers is shared between ABIs with different long double properties, MIPS (o32 has long double = double, other ABIs use ldbl-128) and SPARC (32-bit has optional long double, 64-bit has required long double), need their own bits/long-double.h headers. As with bits/wordsize.h, multiple-include protection for this header is generally implicit through the include guards on sys/cdefs.h, and multiple inclusion is harmless in any case. There is one subtlety: the header must not define __LONG_DOUBLE_MATH_OPTIONAL if __NO_LONG_DOUBLE_MATH was defined before its inclusion, because doing so breaks how sysdeps/ieee754/ldbl-opt/nldbl-compat.h defines __NO_LONG_DOUBLE_MATH itself before including system headers. Subject to keeping that working, it would be reasonable to move these macros from defined/undefined #ifdef to always-defined 1/0 #if semantics, but this patch does not attempt to do so, just rearranges where the macros are defined. After this patch, the only use of bits/mathdef.h is the alpha one for modifying complex function ABIs for old GCC. Thus, all versions of the header other than the default and alpha versions are removed, as is the include from math.h. Tested for x86_64 and x86.

Fix hypot sNaN handling (bug 20940).
TS 18661-1 generally defines libm functions taking sNaN arguments to return qNaN and raise "invalid", even for the cases where a corresponding qNaN argument would not result in a qNaN return. This includes hypot with one argument being an infinity and the other being an sNaN. This patch duly fixes hypot implementatations in glibc (generic and powerpc) to ensure qNaN, computed by arithmetic on the arguments, is returned in that case. Various implementations do their checks for infinities and NaNs inline by manipulating the representations of the arguments. For simplicity, this patch just uses issignaling to check for sNaN arguments. This could be inlined like the existing code (with due care about reversed quiet NaN conventions, for implementations where that is relevant), but given that all these checks are in cases where it's already known at least one argument is not finite, which should be the uncommon case, that doesn't seem worthwhile unless performance issues are observed in practice. Tested for x86_64, x86, mips64 and powerpc. [BZ #20940] * sysdeps/ieee754/dbl-64/e_hypot.c (__ieee754_hypot): Do not return Inf for arguments Inf and sNaN. * sysdeps/ieee754/flt-32/e_hypotf.c (__ieee754_hypotf): Likewise. * sysdeps/ieee754/ldbl-128/e_hypotl.c (__ieee754_hypotl): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_hypotl.c (__ieee754_hypotl): Likewise. * sysdeps/ieee754/ldbl-96/e_hypotl.c (__ieee754_hypotl): Likewise. * sysdeps/powerpc/fpu/e_hypot.c (TEST_INF_NAN): Do not return Inf for arguments Inf and sNaN.

Fix x86_64/x86 powl handling of sNaN arguments (bug 20916).
The x86_64/x86 powl implementations mishandle sNaN arguments, both by returning sNaN in some cases (instead of doing arithmetic on the arguments to produce the result when NaN arguments result in NaN results) and by treating sNaN the same as qNaN for arguments (1, sNaN) and (sNaN, 0), contrary to TS 18661-1 which requires those cases to return qNaN instead of 1. This patch makes the x86_64/x86 powl implementations follow TS 18661-1 semantics for sNaN arguments; sNaN tests are also added for pow. Given the problems with testing float and double sNaN arguments on 32-bit x86 (sNaN tests disabled because the compiler may convert unnecessarily to a qNaN when passing arguments), no changes are made to the powf and pow implementations there. Tested for x86_64 and x86. [BZ #20916] * sysdeps/i386/fpu/e_powl.S (__ieee754_powl): Do not return 1 for arguments (sNaN, 0) or (1, sNaN).

Fix pow (qNaN, 0) result with -lieee (bug 20919), remove dead parts of wrappers.
The dbl-64 implementation of __ieee754_pow returns a NaN for pow (qNaN, 0) when it should return 1. Normally this is covered up by the wrappers ending up calling __kernel_standard which fixes up the result for this case, but for -lieee the wrappers are bypassed and the bad result gets through as a return value. Now, the wrappers fixing this are dealing with variant error handling that wants a result of NaN for pow (qNaN, 0), and only ever call __kernel_standard for this case if NaN resulted from __ieee754_pow. This leads to a question of whether the dbl-64 code might be deliberately returning NaN in order to use those code paths. However, I can find no sign that this is deliberate. If it were deliberate one would expect other implementations to do the same, and would expect the return of NaN to be very old, but it appears it came in by accident when the present e_pow.c implementation replaced an fdlibm implementation in 2001. So it appears to be unintended that this path through the pow wrapper could be used at all. So this patch fixes the implementation to return 1 in this case as expected. This is consistent with all the other implementations. The relevant path through the wrappers is now unreachable, so is removed (which is the main motivation of this patch: to avoid that path becoming accidentally reachable when implementing TS 18661-1 semantics that pow (sNaN, 0) should return qNaN with "invalid" raised). Another path that would require __ieee754_pow (0, 0) to return 0 is also unreachable (as all implementations return 1, in accordance with C99 semantics), so is removed as well. Note: we don't have anything set up to test -lieee, which in any case is obsolescent (at some point we should remove the ability for new programs to access _LIB_VERSION or define matherr and have it called by glibc). So testing will be implicit through sNaN tests added when making sNaN inputs work correctly for pow functions. Tested for x86_64 and x86.

Add llogb, llogbf, llogbl.
TS 18661-1 defines llogb functions that are like ilogb except that they return long int instead of int. Corresponding FP_LLOGB* macros are defined, whose values are required to have the obvious correspondence to those of the FP_ILOGB* macros. This patch implements these functions and macros for glibc. llogb uses the type-generic infrastructure, with an implementation similar to the wrapper for ilogb but with additional conversion from FP_ILOGB* to FP_LLOGB*; this approach avoids needing to modify or duplicate any of the architecture-specific ilogb implementations. Tests are also based on those for ilogb. Ideally the llogb functions would alias the ilogb ones when long is 32-bit, but such aliasing requires the associated header declarations of the different-type alias to be hidden, typically by defining macros before including the header (see e.g. how sysdeps/ieee754/dbl-64/wordsize-64/s_llround.c defines lround to __hidden_lround before including <math.h>). The infrastructure for type-generic function implementations does not support defining such macros at present (since C code can't define a macro whose name is determined by other macros). So this patch leaves them as separate functions (similar to e.g. scalbln and scalbn being separate in such a case as well), but with the remapping of FP_ILOGB* to FP_LLOGB* conditioned out in the case where it would be the identity map.

Continuing the refactoring of bits/mathdef.h, this patch stops it defining FP_ILOGB0 and FP_ILOGBNAN, moving the required information to a new header bits/fp-logb.h. There are only two possible values of each of those macros permitted by ISO C. TS 18661-1 adds corresponding macros for llogb, and their values are required to correspond to those of the ilogb macros in the obvious way. Thus two boolean values - for which the same choices are correct for most architectures - suffice to determine the value of all these macros, and by defining macros for those boolean values in bits/fp-logb.h we can then define the public FP_* macros in math.h and avoid the present duplication of the associated feature test macro logic. This patch duly moves to bits/fp-logb.h defining __FP_LOGB0_IS_MIN and __FP_LOGBNAN_IS_MIN. Default definitions of those to 0 are correct for both architectures, while ia64, m68k and x86 get their own versions of bits/fp-logb.h to reflect their use of values different from the defaults. The patch renders many copies of bits/mathdef.h trivial (needed only to avoid the default __NO_LONG_DOUBLE_MATH). I'll revise <https://sourceware.org/ml/libc-alpha/2016-11/msg00865.html> accordingly so that it removes all bits/mathdef.h headers except the default one and the alpha one, and arranges for the header to be included only by complex.h as the only remaining use at that point will be for the alpha ABI issues there. Tested for x86_64 and x86. Also did compile-only testing with build-many-glibcs.py (using glibc sources from before the commit that introduced many build failures with undefined __GI___sigsetjmp). * bits/fp-logb.h: New file. * sysdeps/ia64/bits/fp-logb.h: Likewise. * sysdeps/m68k/m680x0/bits/fp-logb.h: Likewise. * sysdeps/x86/bits/fp-logb.h: Likewise. * math/Makefile (headers): Add bits/fp-logb.h. * math/math.h: Include <bits/fp-logb.h>.

Refactor FP_FAST_* into bits/fp-fast.h.
Continuing the refactoring of bits/mathdef.h, this patch moves the FP_FAST_* definitions into a new bits/fp-fast.h header. Currently this is only for FP_FAST_FMA*, but in future it would be the appropriate place for the FP_FAST_* macros from TS 18661-1 as well. The generic bits/mathdef.h header defines these macros based on whether the compiler defines __FP_FAST_*. Most architecture-specific headers, however, fail to do so, meaning that if the architecture (or some particular processors) does in fact have fused operations, and GCC knows to use them inline, the FP_FAST_* macros will still not be defined. By refactoring, this patch causes the generic version (based on __FP_FAST_*) to be used in more cases, and so the macro definitions to be more accurate. Architectures that already defined some or all of these macros other than based on the predefines have their own versions of fp-fast.h, which are arranged so they define FP_FAST_* if either the architecture-specific conditions are true or __FP_FAST_* are defined. After this refactoring, various bits/mathdef.h headers for architectures with long double = double are semantically identical to the generic version. The patch removes those headers that are redundant. (In fact two of the four removed were already redundant before this patch because they did use __FP_FAST_*.) Tested for x86_64 and x86, and compilation-only with build-many-glibcs.py. * bits/fp-fast.h: New file. * sysdeps/aarch64/bits/fp-fast.h: Likewise. * sysdeps/powerpc/bits/fp-fast.h: Likewise. * math/Makefile (headers): Add bits/fp-fast.h. * math/math.h: Include <bits/fp-fast.h>. * bits/mathdef.h (FP_FAST_FMA): Remove.

Add setpayloadsig, setpayloadsigf, setpayloadsigl.
TS 18661-1 defines functions for manipulating the payloads of NaNs. This patch implements the setpayloadsig functions for glibc; these are like the setpayload functions, but produce a signaling NaN instead of a quiet NaN. The substance of the implementation was included with the setpayload implementation, so the new files here just need to wrap the main files with different defines to build the new functions. Because the functions store a signaling NaN via a pointer and the libm-test macros choose a suitable initial value for the variable in such a case by comparing with the expected value, the relevant macro needs to clear exceptions after FE_INVALID may have been raised by that comparison. Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (setpayloadsig): New declaration. * math/Versions (setpayloadsig): New libm symbol at version GLIBC_2.25.

Refactor float_t, double_t information into bits/flt-eval-method.h.
At present, definitions of float_t and double_t are split among many bits/mathdef.h headers. For all but three architectures, these types are float and double. Furthermore, if you assume __FLT_EVAL_METHOD__ to be defined, that provides a more generic way of determining the correct values of these typedefs. Defining these typedefs more generally based on __FLT_EVAL_METHOD__ was previously proposed by Paul Eggert in <https://sourceware.org/ml/libc-alpha/2012-02/msg00002.html>. This patch refactors things in the way I proposed in <https://sourceware.org/ml/libc-alpha/2016-11/msg00745.html>. A new header bits/flt-eval-method.h defines a single macro, __GLIBC_FLT_EVAL_METHOD, which is then used by math.h to define float_t and double_t. The default is based on __FLT_EVAL_METHOD__ (although actually a default to 0 would have the same effect for current ports, because ports where values other than 0 or 16 are possible all have their own headers). To avoid changing the existing semantics in any case, including for compilers not defining __FLT_EVAL_METHOD__, architecture-specific files are then added for m68k, s390, x86 which replicate the existing semantics. At least with __FLT_EVAL_METHOD__ values possible with GCC, there should be no change to the choices of float_t and double_t for any supported configuration. Architecture maintainer notes: * m68k: sysdeps/m68k/m680x0/bits/flt-eval-method.h always defines __GLIBC_FLT_EVAL_METHOD to 2 to replicate the existing logic. But actually GCC defines __FLT_EVAL_METHOD__ to 0 if TARGET_68040. It might make sense to make the header prefer to base things on __FLT_EVAL_METHOD__ if defined, like the x86 version, and so make the choices of these types more accurate (with a NEWS entry as for the other changes to these types on particular architectures). * s390: sysdeps/s390/bits/flt-eval-method.h always defines __GLIBC_FLT_EVAL_METHOD to 1 to replicate the existing logic. As previously discussed, it might make sense in coordination with GCC to eliminate the historic mistake, avoid excess precision in the -fexcess-precision=standard case and make the typedefs match (with a NEWS entry, again). Tested for x86-64 and x86. Also did compilation-only testing with build-many-glibcs.py. * bits/flt-eval-method.h: New file. * sysdeps/m68k/m680x0/bits/flt-eval-method.h: Likewise. * sysdeps/s390/bits/flt-eval-method.h: Likewise. * sysdeps/x86/bits/flt-eval-method.h: Likewise. * math/Makefile (headers): Add bits/flt-eval-method.h. * math/math.h: Include <bits/flt-eval-method.h>.

Fix SH4 FP_ILOGB0 (bug 20859).
ISO C requires that the value of FP_ILOGB0 must be INT_MIN or -INT_MAX. In sysdeps/sh/sh4/bits/mathdef.h, it's 0x80000001; that is, a positive unsigned value that would be -INT_MAX if converted to int, which is not valid (there's no actual constraint on the type, but whatever the type the integer value must be one of the two permitted, and types other than int don't really make sense). This patch makes the ABI-compatible change to (-0x7fffffff). (The testcase handles positive and negative sign separately to avoid any issues with implicit conversions that could result in e.g. INT_MIN converted to uintmax_t wrongly passing.) Tested (compilation only) with build-many-glibcs.py. [BZ #20859] * sysdeps/sh/sh4/bits/mathdef.h (FP_ILOGB0): Define to (-0x7fffffff) instead of 0x80000001. * math/test-fp-ilogb-constants.c: New file. * math/Makefile (tests): Add test-fp-ilogb-constants. |

Fix default float_t definition (bug 20855).
The default (top-level) version of bits/mathdef.h defines float_t to double. It is used on ColdFire, MicroBlaze, Nios II and SH3, all of which define FLT_EVAL_METHOD to 0, so float_t should be float (and C11 requires a certain correspondence between these typedefs and FLT_EVAL_METHOD values). I proposed fixing this default in <https://sourceware.org/ml/libc-alpha/2015-01/msg00499.html>, with no objections from architecture maintainers, and this patch makes that fix. As noted in the NEWS entry added, this might affect the ABIs of non-glibc libraries (ImageMagick has been mentioned in gcc-patches discussion of the S/390 case - which is unaffected by this patch), but as noted in my previous message, affected libraries would have problems with -mfpmath=sse anyway on 32-bit x86. A (compilation) testcase is added to verify the required correspondence of typedefs to FLT_EVAL_METHOD values. This test is built with -fexcess-precision=standard to avoid any issues with GCC 7 on S/390 providing a more accurate FLT_EVAL_METHOD definition in the default (no excess precision) mode. (This will also be usable to test a fix for the recently reported bug about these typedefs on x86_64 -mfpmath=387, as architecture-specific tests can be added that It is entirely possible that the fixed default makes some architecture-specific versions of bits/mathdef.h semantically equivalent to the default version and so no longer required. I don't intend to investigate that separately from the refactoring I proposed in <https://sourceware.org/ml/libc-alpha/2016-11/msg00745.html>, which will create as few header variants as possible for each group of definitions. Tested (compilation only) with build-many-glibcs.py.

Add setpayload, setpayloadf, setpayloadl.
TS 18661-1 defines functions for manipulating the payloads of NaNs. This patch implements the setpayload functions for glibc; these set a number (pointed to by a function argument) to a quiet NaN with the given payload, or to +0 if the given payload is not valid. The implementations are structured to allow the substance of the implementation to be shared with the setpayloadsig functions when those are added. The semantics in the TS are not entirely clear in the case where the payload passed to the function is zero (see discussion on the WG14 reflector last month). This patch implements what seems the most sensible interpretation, that -0 is never valid to give as the payload, but +0 is valid in the case where the kind of NaN being generated has its high mantissa bit set so payload 0 is actually possible in such a NaN. Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (setpayload): New declaration. * math/Versions (setpayload): New libm symbol at version GLIBC_2.25.

Refactor some libm type-generic macros.
This patch refactors some type-generic libm macros, in both math.h and math_private.h, to be based on a common __MATH_TG macro rather than all replicating similar logic to choose a function to call based on the type of the argument. This should serve to illustrate what I think float128 support for such macros should look like: common macros such as __MATH_TG may need different definitions depending on whether float128 is supported in glibc, so that the individual macros themselves do not need conditionals on float128 support.

Add missing include for stdlib.h.
The test math/test-nan-overflow uses malloc without including stdlib.h. On -Os builds for i486 the header inclusion order is altered enough that the test fails to build because of the warning which is turned into an error. The obvious fix is to include stdlib.h since malloc is being used directly. |

As with the iscanonical macro, these functions are oriented to the decimal floating-point case, where some values have both canonical and noncanonical representations. However, the functions have a return value that says whether they succeeded in storing a canonical result; thus, they can fail for the case of an invalid representation (while still not making any particular choice from among multiple equally canonical valid representations of the same value). Since no floating-point formats in glibc actually have noncanonical valid representations, a type-generic implementation of these functions can be used that expects iscanonical to return 0 only for invalid representations. Now that iscanonical is used within libm.so, libm_hidden_proto / libm_hidden_def are added for __iscanonicall. The definition of these functions is intended to correspond to a convertFormat operation to the same floating-point format. Thus, they convert signaling NaNs to quiet NaNs, raising the "invalid" exception. Such a conversion "should" produce "the canonical version of that signaling NaN made quiet". libm-test.inc is made to check NaN payloads for the output of these functions, a new feature (at some point manipulation functions such as fabs and copysign should have tests added that verify payload preservation for them). As however some architectures may not follow the recommended practice of preserving NaN payloads when converting a signaling NaN to quiet, a new math-tests.h macro SNAN_TESTS_PRESERVE_PAYLOAD is added, and defined to 0 for non-NAN2008 MIPS; any other architectures seeing test failures for lack of payload preservation in this case should also define this macro to 0. (If any cases arise where the sign isn't preserved either, those should have a similar macro added.) The ldbl-96 and ldbl-128ibm tests of iscanonical are renamed and adapted to test canonicalizel as well on the same representations.
