* Use libm_alias_ldouble for ldbl-128 functions.Joseph Myers2017-10-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes ldbl-128 functions use libm_alias_ldouble to define function aliases. float128_private.h is updated accordingly. 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). Tested for x86_64, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * sysdeps/ieee754/float128/float128_private.h: Include <libm-alias-ldouble.h> and <libm-alias-float128.h>.

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.

* Define HIGH_ORDER_BIT_IS_SET_FOR_SNAN to 0 or 1.Joseph Myers2016-10-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the HIGH_ORDER_BIT_IS_SET_FOR_SNAN macro from being defined or undefined to the preferred convention of always being defined, to either 0 or 1, so allowing typo-proof tests with #if. The macro is moved from math_private.h to a new header nan-high-order-bit.h to make it easy for all architectures to define, either through the sysdeps/generic version of the header or through providing their own version of the header, without needing #ifndef in the generic math_private.h to give a default definition. The move also allows the macro to be used without needing math_private.h to be included; the immediate motivation of this patch is to allow tests to access this information (to know what kinds of NaNs 0 is a valid payload for) without needing to include math_private.h. Existing C level rather than preprocessor conditionals at all, but this patch does not make such a change). Tested for x86_64 and x86 (testsuite); also verified for x86_64, x86, mips64 and powerpc that installed stripped shared libraries are unchanged by the patch. * sysdeps/generic/nan-high-order-bit.h: New file. * sysdeps/hppa/nan-high-order-bit.h: Likewise. * sysdeps/mips/nan-high-order-bit.h: Likewise. * sysdeps/hppa/math_private.h: Remove file. * sysdeps/mips/math_private.h (HIGH_ORDER_BIT_IS_SET_FOR_SNAN): Do not define here. * sysdeps/ieee754/dbl-64/s_issignaling.c: Include <nan-high-order-bit.h>. [HIGH_ORDER_BIT_IS_SET_FOR_SNAN]: Test with #if not #ifdef. * sysdeps/ieee754/dbl-64/s_totalorder.c: Include <nan-high-order-bit.h>.

* Add totalordermag, totalordermagf, totalordermagl.Joseph Myers2016-10-151-0/+47
In addition to the totalorder functions, TS 18661-1 defines totalordermag functions, which do the same comparison but on the absolute values of the arguments. This patch implements these functions for glibc, including the type-generic macro in <tgmath.h>. In general the implementations are similar to but simpler than those for the totalorder functions. Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (totalordermag): New declaration. * math/tgmath.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (totalordermag): New macro. * math/Versions (totalordermag): New libm symbol at version GLIBC_2.25. (totalordermagf): Likewise. (totalordermagl): Likewise. * math/Makefile (libm-calls): Add s_totalordermagF. * math/libm-test.inc (totalordermag_test_data): New array. (totalordermag_test): New function. (main): Call totalordermag_test. * math/test-tgmath.c (NCALLS): Increase to 125. (F(compile_test)): Call totalordermag. (F(totalordermag)): New function. * manual/arith.texi (FP Comparison Functions): Document totalordermag, totalordermagf and totalordermagl. * manual/libm-err-tab.pl: Update comment on interfaces without ulps tabulated. * sysdeps/ieee754/dbl-64/s_totalordermag.c: New file. * sysdeps/ieee754/dbl-64/wordsize-64/s_totalordermag.c: Likewise. * sysdeps/ieee754/flt-32/s_totalordermagf.c: Likewise. * sysdeps/ieee754/ldbl-128/s_totalordermagl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_totalordermagl.c: Likewise. * sysdeps/ieee754/ldbl-96/s_totalordermagl.c: Likewise. * sysdeps/ieee754/ldbl-opt/nldbl-totalordermag.c: Likewise. * sysdeps/ieee754/ldbl-opt/Makefile (libnldbl-calls): Add totalordermag.
