* Support strfromf64x alias.Joseph Myers2017-11-241-1/+12
| | | | | | | | | | | | | | | | | | | | | This patch adds support for defining strfromf64x as a function alias (of strfroml or strfromf128, as appropriate) when _Float64x is supported. Tested for x86_64, including in conjunction with _Float64x support patches, and also tested build for other configurations (in conjunction with _Float64x support patches) with build-many-glibcs.py to cover the various different files needing updating to define these aliases. * stdlib/strfroml.c: Always include <stdlib.h>. [__HAVE_FLOAT64X_LONG_DOUBLE] (strfromf64x): Define and later undefine as macro and define as weak alias. * sysdeps/ieee754/float128/strfromf128.c: Include <bits/floatn.h>. [__HAVE_FLOAT64X && !__HAVE_FLOAT64X_LONG_DOUBLE]: Include <stdlib.h>. [__HAVE_FLOAT64X && !__HAVE_FLOAT64X_LONG_DOUBLE] (strfromf64x): Define and later undefine as macro and define as weak alias.

* Move some float128 symbol version definitions.Joseph Myers2017-10-161-109/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Include <float128-abi.h>. * stdlib/Versions ... and here. Include <float128-abi.h>
* Use libm_alias_ldouble for ldbl-128 functions.Joseph Myers2017-10-061-0/+6

Most of the ldbl-64-128 wrappers are removed as no longer needed with this change (leaving those that involve versioning for functions in libc or that shouldn't be exported from libm for _Float128 / _Float64x types with the same format as long double).

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.

* float128: Add signbit alternative for old compilersGabriel F. T. Gomes2017-06-301-1/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In math/math.h, __MATH_TG will expand signbit to __builtin_signbit*, e.g.: __builtin_signbitf128, before GCC 6. However, there has never been a __builtin_signbitf128 in GCC and the type-generic builtin is only available since GCC 6. For older GCC, this patch defines __builtin_signbitf128 to __signbitf128, so that the internal function is used instead of the non-existent builtin. This patch also changes the implementation of __signbitf128, because it was reusing the implementation of __signbitl from ldbl-128, which calls __builtin_signbitl. Using the long double version of the builtin is not correct on machines where _Float128 is ABI-distinct from long double (i.e.: ia64, powerpc64le, x86, x86_84). The new implementation does not rely on builtins when being built with GCC versions older than 6.0. The new code does not currently affect powerpc64le builds, because only GCC 6.2 fulfills the requirements from configure. It might affect powerpc64le builds if those requirements are backported to older versions of the compiler. The new code affects x86_64 builds, since glibc is supposed to build correctly with older versions of GCC. Tested for powerpc64le and x86_64. * include/math.h (__signbitf128): Define as hidden. * sysdeps/ieee754/float128/s_signbitf128.c (__signbitf128): Reimplement without builtins. * sysdeps/ia64/bits/floatn.h [!__GNUC_PREREQ (6, 0)] (__builtin_signbitf128): Define to __signbitf128. * sysdeps/powerpc/bits/floatn.h: Likewise. * sysdeps/x86/bits/floatn.h: Likewise.
* Add libio-mtsafe flags to the build of strfromf128Gabriel F. T. Gomes2017-06-231-0/+4
| | | | | | | | | | | Similar to the other functions in the strfrom class, strfromf128 calls __printf_fp in order to convert the floating-point value to characters. This requires the value of IO_MTSAFE_IO. Tested for powerpc64le and s390x. * sysdeps/ieee754/float128/Makefile (CFLAGS-strfromf128.c): Add $(libio-mtsafe) to get the value of IO_MTSAFE_IO.
* Fix float128_private.h redefinition of SET_RESTORE_ROUNDL.Joseph Myers2017-06-221-1/+1
| | | | | | | | | | | | | | | | As with other long double identifiers, float128_private.h has a redefinition of SET_RESTORE_ROUNDL. However, that redefinition is broken, since this is a macro with one argument being defined to take no arguments. This patch fixes the redefinition. (x86_64 needs the redefinition because SET_RESTORE_ROUNDL only changes the x87 rounding mode, whereas _Float128 arithmetic uses the SSE rounding mode instead on x86_64.) Tested for x86_64 (in conjunction with float128 patches). * sysdeps/ieee754/float128/float128_private.h [SET_RESTORE_ROUNDF128] (SET_RESTORE_ROUNDL): Take an argument and pass it to SET_RESTORE_ROUNDF128.
* Make float128_private.h work with generic ieee754.h.Joseph Myers2017-06-221-0/+4
| | | | | | | | | | | | | | | | | | float128_private.h redefines ieee754.h identifiers ieee854_long_double and IEEE854_LONG_DOUBLE_BIAS to map them to identifiers from ieee754_float128.h. This causes problems when ieee754.h is included after float128_private.h and it's a version of ieee754.h that also defines those identifiers; specifically, sysdeps/ieee754/ieee754.h, which defines those identifiers for the x86 extended format. This patch fixes this by ensuring an include of ieee754.h from float128_private.h before the redefinitions. Tested for x86_64 (in conjunction with float128 patches). * sysdeps/ieee754/float128/float128_private.h: Include <ieee754.h>.
* Fix float128 uses of xlocale.h.Joseph Myers2017-06-223-3/+3
| | | | | | | | | | | | | | Three float128 files still include xlocale.h after it was removed. I don't know why this didn't cause problems for powerpc64le float128 testing; it did cause problems for my x86_64 float128 testing. This patch changes the includes to use bits/types/locale_t.h. Tested for x86_64 (in conjunction with float128 patches). * sysdeps/ieee754/float128/strtof128_l.c: Include <bits/types/locale_t.h> instead of <xlocale.h>. * sysdeps/ieee754/float128/wcstof128.c: Likewise. * sysdeps/ieee754/float128/wcstof128_l.c: Likewise.

* float128: Add _Float128 make bits to libm.Paul E. Murphy2017-05-092-0/+148
This adds the appropriate common bits for a platform to enable float128 and expose ABI. * math/Makefile: (type-float128-suffix): New variable (type-float128-routines): Likewise (type-float128-yes): Likewise (types): Append float128 if supported (types-basic): New variable to control the use of templates for float, double, and long double, but not for float128 or newer types. (type-basic-foreach): Likewise. * sysdeps/ieee754/float128/Makeconfig: New file. * sysdeps/ieee754/float128/Versions: New file.
