Add _FloatN, _FloatNx M_* constants.
Continuing the preparation for additional _FloatN / _FloatNx type support, this patch adds M_* constants for such types. The decimal expansions used are all the same as used for _Float128; there's no need to reduce the precision used. In the case of _Float128x, #error is used because the constants would need additional precision, but how much is needed would depend on the actual _Float128x format used, so it's not possible to add header support simply as part of code that handles all _FloatN / _FloatNx types similarly.

Add bits/floatn.h defines for more _FloatN / _FloatNx types.
The bits/floatn.h header currently only has defines relating to _Float128. This patch adds defines relating to other _FloatN / _FloatNx types. The approach taken is to add defines for all _FloatN / _FloatNx types known to GCC, and to put them in a common bits/floatn-common.h header included at the end of all the individual bits/floatn.h headers. If in future some defines become different for different glibc configurations, they will move out into the separate bits/floatn.h headers. Some defines are expected always to be the same across glibc ports. Corresponding defines are nevertheless put in this header. The intent is that where there are conditionals (in headers or in non-installed files) that can just repeat the same or nearly the same logic for each floating-point type, they should do so, even if in fact the cases for some types could be unconditionally present or absent because the same conditionals are true or false for all glibc configurations. This should make the glibc code with such conditionals easier to read, because the reader can just see that the same conditionals are repeated for each type, rather than seeing different conditionals for different types and needing to reason, at each location with such differences, why those differences are indeed correct there. (Cases involving per-format rather than per-type logic are more likely still to need differences in how they handle different types.) Having such defines and conditionals also helps in incremental preparation for adding _Float32 / _Float64 / _Float32x / _Float64x function aliases. I intend subsequent patches to add such conditionals corresponding to those already present for _Float128, as well as making more architecture-specific function implementations use common macros to define aliases in preparation for adding such _FloatN / _FloatNx aliases.

Let signbit use the builtin in C++ mode with gcc < 6.x (bug 22296)
When using gcc < 6.x, signbit does not use the type-generic __builtin_signbit builtin, instead it uses __MATH_TG. However, when library support for float128 is available, __MATH_TG uses __builtin_types_compatible_p, which is not available in C++ mode. On the other hand, libstdc++ undefines (in cmath) many macros from math.h, including signbit, so that it can provide its own functions. However, during its configure tests, libstdc++ just tests for the availability of the macros (it does not undefine them, nor does it provide its own functions). Finally, libstdc++ configure tests include math.h and get the definition of signbit that uses __MATH_TG (and __builtin_types_compatible_p). Since libstdc++ does not undefine the macros during its configure tests, they fail. This patch lets signbit use the builtin in C++ mode when gcc < 6.x is used. This allows the configure test in libstdc++ to work. Tested for x86_64. [BZ #22296] * math/math.h: Let signbit use the builtin in C++ mode with gcc < 6.x Cc: Gabriel F. T.

Move some float128 symbol version definitions.
With support for _Float128 functions on platforms where that type has the same ABI as long double, as well as on platforms where it is ABI-distinct, those functions will need to be exported from glibc's shared libraries at appropriate symbol versions in each case. This patch avoids duplication of lists of symbols to export by moving the symbols other than __* to math/Versions and stdlib/Versions. There, they are conditional on <float128-abi.h> defining FLOAT128_VERSION and a default version of that header is added that does not define that macro. Enabling the float128 function aliases will then include adding a sysdeps/ieee754/ldbl-128/float128-abi.h that defines FLOAT128_VERSION to GLIBC_2.27. Symbols __* remain in sysdeps/ieee754/float128/Versions; those symbols should be present only once per floating-point format, not once per type. Note that if any platforms currently lacking support for a type with binary128 format get glibc support for such a type in future (whether only as _Float128, or also as a new long double format), and new libm functions (present for all types) have been added by then, additional macros will be needed to allow such functions to get a version of the form "GLIBC_2.28 if the platform had _Float128 support by then, or the later version at which that platform had _Float128 support added". This is not however a preexisting condition, but would have applied equally to the existing support for _Float128 as an ABI-distinct type. New all-type libm functions should just be added to the appropriate symbol version (currently GLIBC_2.27) for all types, with such special-case handling for _Float128 versions (and _Float64x as well in future) waiting until someone actually wants to add support for _Float128 to an existing platform after a release in which that platform and a post-2.26 libm function had support but that platform lacked _Float128 support. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. Also tested in conjunction with the remaining changes to enable float128 aliases. * sysdeps/generic/float128-abi.h: New file. * sysdeps/ieee754/float128/Versions (FLOAT128_VERSION): Move non-__prefixed symbols to .... * math/Versions: ... here.

Support running libm tests for float128 as alias for long double.
This patch adds support for running libm tests for float128 in the case where the float128 functions are aliases of long double functions. In this case, the sysdeps Makeconfig file (i.e. sysdeps/ieee754/ldbl-128/Makeconfig) will need to define "float128-alias-fcts = yes" to enable the tests. Tested for x86_64. Also tested with build-many-glibcs.py; installed stripped shared libraries are unchanged by the patch. Also tested together with changes to enable the float128 aliases. * math/Makefile (test-types): Add $(type-float128-$(float128-alias-fcts)). * math/test-float128.h (TYPE_STR): Define conditional on [FLT128_MANT_DIG == LDBL_MANT_DIG].

Run libm long double tests for long double = double.
All interfaces in the glibc API ought to be covered by the testsuite, even where they alias other interfaces. This patch arranges for libm tests to be run for long double when it aliases double; previously those tests were run only for the floating-point types with distinct formats. The long double tests are made to use the double ulps values in this case, as having a separate duplicate set of ulps for them seems unnecessary; to accommodate that, the test-<type>.h headers now specify the macro indexing into the ulps array explicitly instead of having it computed from PREFIX. Nothing special is done about vector function tests. None are supported for any long double = double platforms, and supporting vector functions for a type alias such as _Float32 would not simply fall out of adding the scalar aliases for that type - it would require vector function wrappers like those for *_finite (or, better, a new GCC feature to allow specifying the asm name for vector functions independently of that for scalar ones, as previously discussed), so it seems reasonable to require the sysdeps makefile setting of libmvec-tests to be updated if any such tests are to be run for type aliases. Tested for x86_64 and arm. * math/Makefile (test-types-basic): New variable. (test-types): Likewise. (libm-test-support): Use $(test-types) instead of $(types). (libm-tests-base-normal): Likewise.

Add libm_alias_*_other_r macros.
Some libm functions are unable to use the generic alias macros such as libm_alias_double because they have special symbol versioning requirements for the main float, double or long double public names. To facilitate adding _FloatN / _FloatNx function aliases in future, it's still desirable to have generic macros those functions can use as far as possible. This patch adds macros such as libm_alias_double_other, which only define names for _FloatN / _FloatNx aliases, not for float / double / long double. As present, all these new macros do nothing, but they are called in the appropriate places in macros such as libm_alias_double. This patch also arranges for lgamma implementations, and the recently added optimized float function implementations, to use the new macros to make them ready for addition of _FloatN / _FloatNx aliases. Tested for x86_64, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * sysdeps/generic/libm-alias-double.h (libm_alias_double_other_r): New macro.

Use generic macros for lgamma_r function aliases.
Continuing the use of generic macros for defining libm function aliases, in preparation for adding more _FloatN / _FloatNx function names, this patch makes the lgamma_r functions use such macros. declare_mgen_alias_r becomes a standard macro in math-type-macros.h instead of being locally defined in w_lgamma_r_templace.c. This in turn must be defined by each math-type-macros-<type>.h. Rather than providing an unused default in math-type-macros.h, that header is made to give an error if math-type-macros-<type>.h failed to define declare_mgen_alias or declare_mgen_alias_r. The compat lgamma_r wrappers are updated similarly. The ldbl-opt versions are removed as no longer needed. Tested for x86_64, and with build-many-glibcs.py. Installed stripped shared libraries are unchanged except for powerpc64le (where the usual issue applies that an ldbl-opt long double function previously used long_double_symbol unconditionally and now the symbol versions on powerpc64le mean weak_alias is used instead, resulting in the same symbol versions in the final shared library but still enough difference in the input objects for that library not to be byte-identical). * sysdeps/generic/math-type-macros.h [!declare_mgen_alias]: Give error.

Add C++ versions of iscanonical for ldbl-96 and ldbl-128ibm (bug 22235)
All representations of floating-point numbers in types with IEC 60559 binary exchange format are canonical. On the other hand, types with IEC 60559 extended formats, such as those implemented under ldbl-96 and ldbl-128ibm, contain representations that are not canonical. TS 18661-1 introduced the type-generic macro iscanonical, which returns whether a floating-point value is canonical or not. In Glibc, this type-generic macro is implemented using the macro __MATH_TG, which, when support for float128 is enabled, relies on __builtin_types_compatible_p to select between floating-point types. However, this use of iscanonical breaks C++ applications, because the builtin is only available in C mode. This patch provides a C++ implementation of iscanonical that relies on function overloading, rather than builtins, to select between floating-point types. Unlike the C++ implementations for iszero and issignaling, this implementation ignores __NO_LONG_DOUBLE_MATH. The double type always matches IEC 60559 double format, which is always canonical. Thus, when double and long double are the same (__NO_LONG_DOUBLE_MATH), iscanonical always returns 1 and is not implemented with __MATH_TG. Tested for powerpc64, powerpc64le and x86_64.

Simplify C99 isgreater macros

Optimized generic expf and exp2f with wrappers
Based on new expf and exp2f code from https://github.com/ARM-software/optimized-routines/ with wrapper on aarch64: expf reciprocal-throughput: 2.3x faster expf latency: 1.7x faster without wrapper on aarch64: expf reciprocal-throughput: 3.3x faster expf latency: 1.7x faster without wrapper on aarch64: exp2f reciprocal-throughput: 2.8x faster exp2f latency: 1.3x faster libm.so size on aarch64: .text size: -152 bytes .rodata size: -1740 bytes expf/exp2f worst case nearest rounding error: 0.502 ulp worst case non-nearest rounding error: 1 ulp Error checks are inline and errno setting is in separate tail called functions, but the wrappers are kept in this patch to handle the _LIB_VERSION==_SVID_ case. (So e.g. errno is set twice for expf calls and once for __expf_finite calls on targets where the new code is used.) Double precision arithmetics is used which is expected to be faster on most targets (including soft-float) than using single precision and it is easier to get good precision result with it. Const data is kept in a separate translation unit which complicates maintenance a bit, but is expected to give good code for literal loads on most targets and allows sharing data across expf, exp2f and powf. (This data is disabled on i386, m68k and ia64 which have their own expf, exp2f and powf code.) Some details may need target specific tweaks: - best convert and round to int operation in the arg reduction may be different across targets. - code was optimized on fma target, optimal polynomial eval may be different without fma. - gcc does not always generate good code for fp bit representation access via unions or it may be inherently slow on some targets. The libm-test-ulps will need adjustment because.. - The argument reduction ideally uses nearest rounded rint, but that is not efficient on most targets, so the polynomial can get evaluated on a wider interval in non-nearest rounding mode making 1 ulp errors common in that case. - The polynomial is evaluated such that it may have 1 ulp error on negative tiny inputs with upward rounding. * math/Makefile (type-float-routines): Add math_errf and e_exp2f_data. * sysdeps/aarch64/fpu/math_private.h (TOINT_INTRINSICS): Define.

Let fpclassify use the builtin when optimizing for size in C++ mode (bug 22146)
When optimization for size is on (-Os), fpclassify does not use the type-generic __builtin_fpclassify builtin, instead it uses __MATH_TG. However, when library support for float128 is available, __MATH_TG uses __builtin_types_compatible_p, which is not available in C++ mode. On the other hand, libstdc++ undefines (in cmath) many macros from math.h, including fpclassify, so that it can provide its own functions. However, during its configure tests, libstdc++ just tests for the availability of the macros (it does not undefine them, nor does it provide its own functions). Finally, when libstdc++ is configured with optimization for size enabled, its configure tests include math.h and get the definition of fpclassify that uses __MATH_TG (and __builtin_types_compatible_p). Since libstdc++ does not undefine the macros during its configure tests, they fail. This patch lets fpclassify use the builtin in C++ mode, even when optimization for size is on. This allows the configure test in libstdc++ to work. Tested for powerpc64le and x86_64. [BZ #22146] math/math.h: Let fpclassify use the builtin in C++ mode, even when optimazing for size. |

Use libm_alias_ldouble in math/.
This patch converts libm function implementations in math/ from using weak_alias to using libm_alias_ldouble to define public function names, in cases where it would be appropriate to define _Float128 / _Float64x aliases for those functions as well (in cases where either or both of those types exist and have the same ABI as long double). This eliminates many ldbl-opt wrappers round these function implementations. Tested for x86_64, and with build-many-glibcs.py. All installed stripped shared libraries are unchanged except for libm.so on powerpc64le. As noted for a previous patch, powerpc64le's use of ldbl-opt means various long double functions get defined using long_double_symbol which gives them an explicit symbol version in the object files, and this patch results in some such functions using weak_alias instead (because powerpc64le never had a previous version of these functions for long double = double); both produce a valid libm.so with the same public symbols at the same versions, but macros expanding to call weak_alias is cleaner in this case. * math/s_fmal.c: Include <libm-alias-ldouble.h>.

Use libm_alias_double in math/.
This patch converts libm function implementations in math/ from using weak_alias to using libm_alias_double to define public function names, in cases where it would be appropriate to define _Float64 / _Float32x aliases for those functions as well. This eliminates many NO_LONG_DOUBLE conditionals and ldbl-opt wrappers round these function implementations. Tested for x86_64. Also tested with build-many-glibcs.py. Binary differences seen are that the different order in which remainder and drem symbols get defined as a result of this patch (the same source file defines the same aliases, but in a different order of definition) changes the order of symbols in the final libm.so when long double = double, and for ldbl-opt configurations, the compat symbols for Bessel functions were previously defined by e.g. "compat_symbol (libm, j0, j0l, GLIBC_2_0)", which declares j0l as a compat symbol based on j0 and so makes j0l weak because j0 is weak, and are now defined (indirectly via the relevant macros) based on e.g. __j0, so are no longer weak because __j0 isn't weak. * math/s_fma.c: Include <libm-alias-double.h>.

Remove ENOSYS math/ function stubs.
The math/ directory has various stub implementations of functions (generally long double functions, plus sqrtf128) that set errno to ENOSYS and print a message. These are a relic of when the long double libm implementation in glibc was originally incomplete. They are only present for a limited set of libm functions, not all those that would need implementing for any hypothetical new long double format, and only for long double (plus sqrtf128), not for other floating-point types. I removed the corresponding ENOSYS tests in the testsuite in <https://sourceware.org/ml/libc-alpha/2013-05/msg00599.html>. I think these stubs are an inherently different case from stubs for functionality needing OS-specific implementations, since floating-point formats are generally standardized between modern processors (a new long double format does not seem likely - I'd expect new ports all to have long double = binary128 or long double = binary64 - though _Float16 functions *f16 are entirely possible in future) and libm functions are generally only expected to fail for domain / range / pole errors, not for other unknown system-specific conditions the way the functions needing OS-specific implementations may fail. This patch removes these stub implementations. The effect (which, as noted above, was actually mostly already the case, given the incompleteness of the set of stubs, and was certainly the case if you wanted your libm port to *work* rather than just build) is that any new long double format needs to provide a full set of functions for the build to succeed; any port using ldbl-128 needs to provide sqrtl (possibly using the soft-fp version from another port); any port using ldbl-96 needs to provide all those functions that all of x86_64/i386/ia64/m68k provide rather than getting from the ldbl-96 directory; any port with _Float128 as a type with a distinct format needs to provide sqrtf128. Tested for x86_64. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * math/e_acoshl.c: Remove. * math/e_acosl.c: Likewise. * math/e_asinl.c: Likewise. * math/e_atan2l.c: Likewise. * math/e_atanhl.c: Likewise. * math/e_coshl.c: Likewise. * math/e_expl.c: Likewise. * math/e_fmodl.c: Likewise. * math/e_gammal_r.c: Likewise. * math/e_hypotl.c: Likewise. * math/e_j0l.c: Likewise. * math/e_j1l.c: Likewise. * math/e_jnl.c: Likewise. * math/e_lgammal_r.c: Likewise. * math/e_log10l.c: Likewise. * math/e_log2l.c: Likewise. * math/e_logl.c: Likewise. * math/e_powl.c: Likewise. * math/e_rem_pio2l.c: Likewise. * math/e_sinhl.c: Likewise. * math/e_sqrtf128.c: Likewise. * math/e_sqrtl.c: Likewise. * math/k_cosl.c: Likewise. * math/k_sinl.c: Likewise. * math/k_tanl.c: Likewise. * math/s_asinhl.c: Likewise. * math/s_atanl.c: Likewise. * math/s_cbrtl.c: Likewise. * math/s_erfl.c: Likewise. * math/s_expm1l.c: Likewise. * math/s_log1pl.c: Likewise. * math/s_tanhl.c: Likewise. |

Use libm_alias_float in math/.
This patch converts libm function implementations in math/ from using weak_alias to using libm_alias_float to define public function names, in cases where it would be appropriate to define _Float32 aliases for those functions as well. expf and exp2f are omitted from this patch, given the in-progress patches that would change their symbol versioning arrangements (at a later stage it will be necessary to add macros that can be used for functions with such symbol versioning arrangements - which will apply to lgammaf as well - but for the initial patches in this area I'm just dealing with easy cases, and any symbol versioning changes to these functions while the work is in progress can effectively just undo the libm_alias_* changes as regards those functions).

Make more libm functions into weak aliases.
Many libm functions define the function as __<func> and then define <func> as a weak alias. This is not at all limited to cases where there is an internal call that has namespace reasons to need to call __<func> instead of <func>. The common macros for creating libm function aliases work on the basis of public function names all being aliases; that is, they define aliases for functions using the above pattern. Thus, where a function just defines the public name <func> directly, changing that to be a weak alias enables a subsequent conversion to the common macros to retain the exact existing symbols (and so be testable by comparison of stripped binaries). This patch converts many existing functions to use the weak alias pattern, as preparation for subsequent conversions to common macros. I do expect that _FloatN/_FloatNx function aliases will end up needing new variants of the common macros that do *not* create the original float / double / long double name of a function - for cases where that name is created specially to give it a particular symbol version, for example - but for functions that can use the most common macros to create all the public names as aliases, it makes sense for them to do so. Regarding the Bessel function wrappers in this patch: only float and double wrappers are changed because the long double wrappers already used the weak alias pattern.

Clear up log1p, ldexp, scalbn, scalbln compat handling.
This patch cleans up how compat symbols / long double versioning are handled for log1p, ldexp, scalbn and scalbln functions. The general principle is to do as much as possible through the type-generic templates. Previously, when errno-setting wrappers were added the compat long double symbols were left pointing directly to the underlying implementations; they are moved to point to the errno-setting wrappers. For the functions also present in libc, compat symbol handling for the libc copies needs to go in ldbl-opt wrappers, but the type-generic templates can handle it for the libm copies. There is no need for w_scalbln_template.c to disable the creation of an unused internal alias (such code made sense in the context of patches trying to avoid any changes to generated code for ease of comparison, but can be removed in a change that specifically does intend to change details of where symbols point). Tested for x86_64, and with build-many-glibcs.py. * math/w_scalbln_template.c (strong_alias): Do not undefine and redefine. * sysdeps/ieee754/ldbl-opt/s_ldexp.c (declare_mgen_alias): Remove macro.

Define and use libm_alias_double.
Continuing the process of setting up common macros for libm function aliases, with a view to using them to define _FloatN / _FloatNx aliases in future, this patch adds a libm_alias_double macro and uses it in the type-generic templates. This macro handles defining aliases for double, and for long double in the NO_LONG_DOUBLE case. It also handles defining compat symbols for long double = double for architectures that changed their long double format. By so doing, it eliminates the need for the M_LIBM_NEED_COMPAT and declare_mgen_libm_compat macros; the single declare_mgen_alias call in each template now suffices to define all required compat symbols. When used for more double functions (not based on type-generic templates), I expect it will eliminate the need for most ldbl-opt wrappers for such functions. A few special cases are needed. __clog10l is a public symbol (for historical reasons) so needs to be given appropriate compat versions for architectures that changed their long double format, but is not defined as an alias using the normal macros since __clog10* are *not* public symbols for _FloatN / _FloatNx types. For scalbn, scalbln and log1p, the changes adding errno setting support for those functions left compat symbols pointing directly to the non-errno-setting implementations. There is no requirement for the compat symbols not to set errno; that just made for the simplest patches at that time. Now, with these common macros, it's natural to redirect the compat symbols to the errno-setting wrappers, which I intend to do in a separate patch. Tested for x86_64, and with build-many-glibcs.py. For ldbl-opt platforms the stripped libm.so binaries are changed (disassembly unchanged) because the details of how the clog10l compat symbol is created mean it ceases to be weak as it was before; for other platforms, stripped libm.so binaries are unchanged. 2017-09-13 Joseph Myers <joseph@codesourcery.com> * sysdeps/generic/libm-alias-double.h: New file. * sysdeps/ieee754/ldbl-opt/libm-alias-double.h: Likewise. * sysdeps/generic/math-type-macros-double.h: Include <libm-alias-double.h>.

Remove declare_mgen_alias_2.
The libm template machinery includes a macro declare_mgen_alias_2, to define two function aliases rather than one. This macro is only used in one place, to define ldexp and scalbn, and only has one nondefault definition, for double in the case where long double has the same format. That definition is because declare_mgen_alias for double, in that case, defines <internal-func>l as an alias of <internal-func>, so cannot be called twice for aliases of the same function. Now, I suspect the <internal-func>l aliases are generally not needed (with maybe a few exceptions such as __clog10l, which is an exported function). But even in the presence of them, there is no need for a special declare_mgen_alias_2 macro for this case. This patch eliminates the need for such a macro by defining __wrap_scalbn<suffix> as an alias of __ldexp<suffix>, and then using that when defining the scalbn public aliases. This is similar to how such internal aliases are created for functions with multiple symbol versions, for example. Tested for x86_64, and with build-many-glibcs.py. (There *are* some cases where installed stripped shared libraries change - not in the generated code but because such changes to static symbols on input to ld, even nonexported symbols that don't affect the code or dynamic symbols, can affect the particular representation in the output of string tables, hash tables etc.) * sysdeps/generic/math-type-macros.h [!declare_mgen_alias_2] (declare_mgen_alias_2): Remove. * sysdeps/generic/math-type-macros-double.h [NO_LONG_DOUBLE && !declare_mgen_alias_2] (declare_mgen_alias_2): Likewise. * math/s_ldexp_template.c (M_SUF (__wrap_scalbn)): Define strong alias.

Prefer new libm function wrappers for !LIBM_SVID_COMPAT.
The initial obsoletion of SVID libm error handling left the old wrappers and __kernel_standard still being used for new ports and static linking, just with macro definitions of _LIB_VERSION and matherr that meant symbols with those names were never actually used and the code for different error handling variants could be optimized out. This patch cleans things up further by eliminating the __kernel_standard use for new ports and static linking. Now, the old wrappers no longer generate any code in the !LIBM_SVID_COMPAT case, while the new errno-only wrappers that were added for float128 support are now also used for float, double and long double in that case. The changes are generally straightforward. The w_scalb*_compat wrappers continue to be used (scalb is obsolescent in the sense of not being supported for float128, but is present in supported standards - the 2001 edition of POSIX and earlier XSI versions - so remains supported for static linking and new ports, as do the float and long double variants that are existing GNU extensions). Those wrappers would only call __kernel_standard in the _LIB_VERSION == _SVID_ case. Since we would like to be able to compile most of glibc without optimization, relying on a static function whose only use is under an if (0) condition being optimized away to avoid an undefined __kernel_standard reference may not be a good idea. Thus, the relevant code in the scalb wrappers has LIBM_SVID_COMPAT conditionals added to guarantee it's not built at all in the case where __kernel_standard does not exist. Just as i386 has its own w_sqrt_compat.c, so w_sqrt.c is also added. ia64 gets dummy w_*.c to prevent those files being built where they would conflict with the ia64 libm, as with its existing w_*_compat.c. Conditions disabling code for !LIBM_SVID_COMPAT are needed in both the math/ wrappers and in the long double wrappers in ldbl-opt (to avoid them setting up aliases and symbol versions for undefined symbols). I hope that future cleanups to how libm function aliases and symbol versioning are done will eliminate the need for most of the ldbl-opt wrappers.

Obsolete pow10 functions.
This patch obsoletes the pow10, pow10f and pow10l functions (makes them into compat symbols, not available for new ports or static linking). The exp10 names for these functions are standardized (in TS 18661-4) and were added in the same glibc version (2.1) as pow10 so source code can change to use them without any loss of portability. Since pow10 is deliberately not provided for _Float128, only exp10, this slightly simplifies moving to the new wrapper templates in the !LIBM_SVID_COMPAT case, by avoiding needing to arrange for pow10, pow10f and pow10l to be defined by those templates.

Simplify NAN definitions.
Similar to my patches for HUGE_VAL and INFINITY. this patch eliminates
the bits/nan.h headers. __builtin_nanf ("") is used to define NAN for
GCC 3.3 and later; the fallback is (0.0f / 0.0f), which is a constant
expression for a quiet NaN of type float, but raises a spurious
"invalid" exception outside static initializers, which seems the best
that can be done purely in standard C. Again, if anyone actually uses
a compiler with its own incompatible extension for producing a
constant quiet NaN, we can add compiler conditionals.
Tested for x86_64.

Simplify HUGE_VAL definitions.
There are various bits/huge_val*.h headers to define HUGE_VAL and related macros. All of them use __builtin_huge_val etc. for GCC 3.3 and later. Then there are various fallbacks, such as using a large hex float constant for GCC 2.96 and later, or using unions (with or without compound literals) to construct the bytes of an infinity, with this last being the reason for having architecture-specific files. Supporting TS 18661-3 _FloatN / _FloatNx types that have the same format as other supported types will mean adding more such macros; needing to add more headers for them doesn't seem very desirable. The fallbacks based on bytes of the representation of an infinity do not meet the standard requirements for a constant expression. At least one of them is also wrong: sysdeps/sh/bits/huge_val.h is producing a mixed-endian representation which does not match what GCC does. This patch eliminates all those headers, defining the macros directly in math.h. For GCC 3.3 and later, the built-in functions are used as now. For other compilers, a large constant 1e10000 (with appropriate suffix) is used. This is like the fallback for GCC 2.96 and later, but without using hex floats (which have no apparent advantage here). It is unambiguously valid standard C for all floating-point formats with infinities, which covers all formats supported by glibc or likely to be supported by glibc in future (C90 DR#025 said that if a floating-point format represents infinities, all real values lie within the range of representable values, so the constraints for constant expressions are not violated), but may generate compiler warnings and wouldn't handle the TS 18661-1 FENV_ROUND pragma correctly. If someone is actually using a compiler with glibc that does not claim to be GCC 3.3 or later, but which has a better way to define the HUGE_VAL macros, we can always add compiler conditionals in with alternative definitions.

Fix bits/math-finite.h _MSUF_ expansion namespace (bug 22028).
The current bits/math-finite.h approach to defining functions for different types, involving math.h defining _MSUF_ and _MSUFTO_ for the function suffixes involved, is not namespace-clean if one of those suffixes (f, l, f128) is defined as a macro by the user before math.h is included; too many levels of macro expansion occur. Instead, those suffixes should appear directly in the expansion of the macro using ## so they don't get expanded even if defined as macros by the user (that is, math.h should be defining __REDIRFROM_X and __REDIRTO_X directly to use those suffixes rather than suffixes being passed as an argument by macro callers). This patch makes that change. Tested for x86_64. [BZ #22028] * math/math.h [__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0] (_MSUF_): Remove macro.

Provide a C++ version of iszero that does not use __MATH_TG (bug 21930)
When signaling nans are enabled (with -fsignaling-nans), the C++ version of iszero uses the fpclassify macro, which is defined with __MATH_TG. However, when support for float128 is available, __MATH_TG uses the builtin __builtin_types_compatible_p, which is only available in C mode. This patch refactors the C++ version of iszero so that it uses function overloading to select between the floating-point types, instead of relying on fpclassify and __MATH_TG. Tested for powerpc64le, s390x, x86_64, and with build-many-glibcs.py. [BZ #21930] * math/math.h [defined __cplusplus && defined __SUPPORT_SNAN__] (iszero): New C++ implementation that does not use fpclassify/__MATH_TG/__builtin_types_compatible_p, when signaling nans are enabled, since __builtin_types_compatible_p is a C-only feature. * math/test-math-iszero.cc: When __HAVE_DISTINCT_FLOAT128 is defined, include ieee754_float128.h for access to the union and member ieee854_float128.ieee.

Simplify math-svid-compat code.
Now there are no more assembly wrappers using _LIB_VERSION or __kernel_standard, the math-svid-compat code can be slighly simplified. math-svid-compat.h no longer needs __ASSEMBLER__ conditionals, and the _LIB_VERSION variable no longer needs to be built for static libm, since all references are now in C code that includes math-svid-compat.h and so gets the macro definition of _LIB_VERSION to _POSIX_ outside the compat case. This patch makes those cleanups. Tested for x86_64, and with build-many-glibcs.py. * math/math-svid-compat.h [!__ASSEMBLER__]: Make code unconditional. * sysdeps/ieee754/s_lib_version.c [!defined SHARED]: Remove conditional code; define contents only for [LIBM_SVID_COMPAT]. |

Use __HAVE_DISTINCT_FLOAT128 in tgmath.h.
When _Float128 is ABI-equivalent to long double, there is no need for tgmath.h to have any special _Float128 handling: it's always OK to call the long double versions of functions for _Float128 arguments in that case, and the logic to determine return types is generic. Thus, this patch changes the use of __HAVE_FLOAT128 to __HAVE_DISTINCT_FLOAT128, as a minor optimization to reduce the size of the macro expansions in the ABI-equivalent case. Tested for x86_64. * math/tgmath.h [__HAVE_FLOAT128]: Change conditional to [__HAVE_DISTINCT_FLOAT128]. |

Clean up bits/math-finite.h for aliasing types.
This patch cleans up how bits/math-finite.h handles types that are ABI-aliases of other types. For such types, no __*_finite functions exist; instead, bits/math-finite.h must redirect calls to a the functions for a canonical choice of type for each floating-point format. (For the actual public interfaces, symbols need exporting for each type, even those that are ABI-aliases, because of standard requirements that programs can declare the functions themselves without including <math.h>, but that does not apply to __*_finite.) At present, there is a special-case conditional in bits/math-finite.h on __MATH_DECLARING_LDOUBLE && defined __NO_LONG_DOUBLE_MATH to handle redirecting long double function calls to double __*_finite. This patch replaces this by a more general mechanism. math.h, before each inclusion of bits/math-finite.h, defines _MSUFTO_ as the suffix to use on the target of redirection, in addition to the existing _MSUF_. This way, __MATH_DECLARING_LDOUBLE can go away, as can the special conditional in bits/math-finite.h. With this patch, math.h is now prepared for the case of supporting float128 functions as aliases of long double ones on platforms where long double is binary128, with _MSUFTO_ appropriately defined for that case, and appropriate _MSUFTO_ definitions can easily be included when supporting _Float32 / _Float64 / _Float32x / _Float64x (which will always be ABI-aliases of another type when supported). Tested for x86_64, and did a compilation test for ARM with build-many-glibcs.py to cover the long double = double case. * math/math.h (_MSUFTO_): Define and undefine for each inclusion of <bits/math-finite.h>.

Fix tgmath.h handling of complex integers (bug 21684).
The tgmath.h macros return a real type not a complex type when an argument is of complex integer type (a GNU extension) and there are no arguments of complex floating type. It seems clear that just as real integers are mapped to double for tgmath.h, so complex integers should be mapped to _Complex double. This patch implements such a mapping. The main complication in fixing this bug is that the tgmath.h macros expand their arguments a large number of times, resulting in exponential blowup of the size of the expansion when calls to tgmath.h macros are used in the arguments of such macros; it would be unfortunate for fixing a bug with a fairly obscure extension to make the macros expand their arguments even more times. Thus, this patch optimizes the definitions of the relevant macros. __tgmath_real_type previously expanded its argument 7 times and now expands it 3 times. __tgmath_complex_type, used in place of __tgmath_real_type only for functions that might return either real or complex types, not for complex functions that always return real types or always return complex types, expands its argument 5 times. So the sizes of the macro expansions from nested macro calls are correspondingly reduced (remembering that each tgmath.h macro expands __tgmath_real_type, or sometimes now __tgmath_complex_type, several times). Sometimes the real return type resulted from calling a complex function and converting the result to a real type; sometimes it resulted from calling a real function, because the logic for determining whether arguments were real or complex, based on sizeof, was confused by integer promotions applying to e.g. short int but not _Complex short int. The relevant tests are converted to use a new macro __expr_is_real, which, by calling __builtin_classify_type rather than comparing the results of two calls to sizeof, also reduces the number of times macros expand their arguments. Although there are reductions in the number of times macros expand their arguments, I do not consider this to fix bug 21660, since a proper fix means each macro expanding its arguments only once (via using new compiler features designed for that purpose). Tested for x86_64. [BZ #21684] * math/tgmath.h (__floating_type): Simplify definitions. (__real_integer_type): New macro. (__complex_integer_type): Likewise. (__expr_is_real): Likewise.

Provide a C++ version of issignaling that does not use __MATH_TG
The macro __MATH_TG contains the logic to select between long double and _Float128, when these types are ABI-distinct. This logic relies on __builtin_types_compatible_p, which is not available in C++ mode. On the other hand, C++ function overloading provides the means to distinguish between the floating-point types. The overloading resolution will match the correct parameter regardless of type qualifiers, i.e.: const and volatile.

Obsolete matherr, _LIB_VERSION, libieee.a.
This patch obsoletes support for SVID libm error handling (the system where a user-defined function matherr is called on a libm function error; only enabled if you also set _LIB_VERSION = _SVID_ or _LIB_VERSION = _XOPEN_) and the use of the _LIB_VERSION global variable to control libm error handling. matherr and _LIB_VERSION are made into compat symbols, not supported for new ports or for static linking. The libieee.a object file (which sets _LIB_VERSION = _IEEE_, so disabling errno setting for some functions) is also removed, and all the related definitions are removed from math.h. The manual already recommends against using matherr, and it's already not supported for _Float128 functions (those use new wrappers that don't support matherr, only errno) - this patch means that it becomes possible to e.g. add sinf32 as an alias to sinf without that resulting in undesired matherr support in sinf32 for existing glibc ports. matherr support is not part of any standard supported by glibc (it was removed in XPG4). Because matherr is a function to be defined by the user, of course user programs defining such a function will still continue to link; it just quietly won't be used. If they try to write to the library's copy of _LIB_VERSION to enable SVID error handling, however, they will get a link error (but if they define their own _LIB_VERSION variable, they won't). I expect the most likely case of build failures from this patch to be programs with unconditional cargo-culted uses of -lieee (based on a notion of "I want IEEE floating point", not any actual requirement for that library). Ideally, the new-port-or-static-linking case would use the new wrappers used for _Float128. This is not implemented in this patch, because of the complication of architecture-specific (powerpc32 and sparc) sqrt wrappers that use _LIB_VERSION and __kernel_standard directly. Thus, the old wrappers and __kernel_standard are still built unconditionally, and _LIB_VERSION still exists in static libm. But when the old wrappers and __kernel_standard are built in the non-compat case, _LIB_VERSION and matherr are defined as macros so code to support those features isn't actually built into static libm or new ports' shared libm after this patch. I intend to move to the new wrappers for static libm and new ports in followup patches. I believe the sqrt wrappers for powerpc32 and sparc can reasonably be removed. GCC already optimizes the normal case of sqrt by generating code that uses a hardware instruction and only calls the sqrt function if the argument was negative (if -fno-math-errno, of course, it just uses the hardware instruction without any check for negative argument being needed). Thus those wrappers will only actually get called in the case of negative arguments, which is not a case it makes sense to optimize for. But even without removing the powerpc32 and sparc wrappers it should still be possible to move to the new wrappers for static libm and new ports, just without having those dubious architecture-specific optimizations in static libm. Everything said about matherr equally applies to matherrf and matherrl (IA64-specific, undocumented), except that the structure of IA64 libm means it won't be converted to using the new wrappers (it doesn't use the old ones either, but its own error-handling code instead). As with other tests of compat symbols, I expect test-matherr and test-matherr-2 to need to become appropriately conditional once we have a system for disabling such tests for ports too new to have the relevant symbols.

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).

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.

Remove NO_LONG_DOUBLE conditionals in libm tests (bug 21607).
As noted in bug 21607, NO_LONG_DOUBLE conditionals in libm tests are no longer effective. For most this is harmless - they were only present because of long double functions not being declared with _LIBC defined, and _LIBC is no longer defined for building most tests. For the few where this is actually relevant to the test, testing LDBL_MANT_DIG > DBL_MANT_DIG is more appropriate as that limits the test to public APIs. This patch fixes the tests accordingly. Tested for x86_64 and arm.

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.

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). This template can also be used for float128, thus reducing the amount of duplicated code that gets added when adding support the new type.

Suppress internal declarations for most of the testsuite.
This patch adds a new build module called 'testsuite'.
IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus
(which means several ad-hoc tests for __cplusplus can go away).
libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is
defined; in particular, _ISOMAC mode does not get config.h
automatically anymore.
There are still quite a few tests that need to see internal gunk of
one variety or another. For them, we now have 'tests-internal' and
'test-internal-extras'; files in this category will still be compiled
with MODULE_NAME=nonlib, and everything proceeds as it always has.
The bulk of this patch is moving tests from 'tests' to
'tests-internal'. There is also 'tests-static-internal', which has
the same effect on files in 'tests-static', and 'modules-names-tests',
which has the *inverse* effect on files in 'modules-names' (it's
inverted because most of the things in modules-names are *not* tests).
For both of these, the file must appear in *both* the new variable and
the old one.
There is also now a special case for when libc-symbols.h is included
without MODULE_NAME being defined at all. (This happens during the
creation of libc-modules.h, and also when preprocessing Versions
files.) When this happens, IS_IN is set to be always false and
_ISOMAC is *not* defined, which was the status quo, but now it's
explicit.
The remaining changes to C source files in this patch seemed likely to
cause problems in the absence of the main change. They should be
relatively self-explanatory. In a few cases I duplicated a definition
from an internal header rather than move the test to tests-internal;
this was a judgement call each time and I'm happy to change those
however reviewers feel is more appropriate.
* Makerules: New subdir configuration variables 'tests-internal'
and 'test-internal-extras'. Test files in these categories will
still be compiled with MODULE_NAME=nonlib. Test files in the
existing categories (tests, xtests, test-srcs, test-extras) are
now compiled with MODULE_NAME=testsuite.
New subdir configuration variable 'modules-names-tests'. Files
which are in both 'modules-names' and 'modules-names-tests' will
be compiled with MODULE_NAME=testsuite instead of
MODULE_NAME=extramodules.
(gen-as-const-headers): Move to tests-internal.
(do-tests-clean, common-mostlyclean): Support tests-internal.
* Makeconfig (built-modules): Add testsuite.
* Makefile: Change libof-check-installed-headers-c and
libof-check-installed-headers-cxx to 'testsuite'.
* Rules: Likewise. Support tests-internal.
* benchtests/strcoll-inputs/filelist#en_US.UTF-8:
Remove extra-modules.mk.
* config.h.in: Don't check for __OPTIMIZE__ or __FAST_MATH__ here.
* include/libc-symbols.h: Move definitions of _GNU_SOURCE,
PASTE_NAME, PASTE_NAME1, IN_MODULE, IS_IN, and IS_IN_LIB to the
very top of the file and rationalize their order.
If MODULE_NAME is not defined at all, define IS_IN to always be
false, and don't define _ISOMAC.
If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are
true, define _ISOMAC and suppress everything else in this file,
starting with the inclusion of config.h.
Do check for inappropriate definitions of __OPTIMIZE__ and
__FAST_MATH__ here, but only if _ISOMAC is not defined.
Correct some out-of-date commentary.
* include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE
and _Mlong_double_ before including math.h.
* include/string.h: If _ISOMAC is defined, don't expose
_STRING_ARCH_unaligned. Move a comment to a more appropriate
location.
* include/errno.h, include/stdio.h, include/stdlib.h, include/string.h
* include/time.h, include/unistd.h, include/wchar.h: No need to

Fix condition for inclusion of math-finite.h for long double

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.
