*	Include libc-header-start.h in include/float.h	Gabriel F. T. Gomes	2017-06-23	1	-0/+3
\| \| \| \| \| \| \| \| \| \| \|	The file include/float.h uses the macro __GLIBC_USE to test for TS 18661-3 support. Such macro is provided by bits/libc-header-start.h, so include it to get the definition. Tested for powerpc64le and s390x. * include/float.h: Include libc-header-start.h to get the definition of __GLIBC_USE.
*	Allow macros prefixed with FLT128 in include/float.h	Gabriel F. T. Gomes	2017-06-12	1	-16/+15
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	TS 18661-3 specifies that macros prefixed with FLTN_ can be defined in float.h, only if __STDC_WANT_IEC_60559_TYPES_EXT__ is defined as a macro before the inclusion of float.h. Since GCC 7.0, these macros are provided under this condition, however, for older versions of GCC, these macros are not provided at all. This patch allows the definitions of such macros in include/float.h for older compilers, if the condition above is met, and even if _ISOMAC is defined. * include/float.h: Allow the definition of macros prefixed with FLT128 even if _ISOMAC is defined, but provided that __STDC_WANT_IEC_60559_TYPES_EXT__ is defined as a macro.
*	float128: Add private _Float128 declarations for libm.	Paul E. Murphy	2017-05-15	1	-0/+31
	Add the necessary bits to the private headers to support building the _Float128 libm functions. A local override for float.h is provided to include the missing FLT128 macros implied by TS 18661-3 for this type when compiling prior to GCC 7. include/complex.h (__kernel_casinhf128): New declaration. * include/float.h: New file. * include/math.h (__finitef128): Add a hidden def. (__isinff128): Likewise. (__isnanf128): Likewise. (__fpclassify): Likewise. (__issignalling): Likewise. (__expf128): Likewise. (__expm1f128): Likewise. * sysdeps/generic/fix-fp-int-convert-overflow.h: (FIX_FLT128_LONG_CONVERT_OVERFLOW): New macro. (FIX_FLT128_LLONG_CONVERT_OVERFLOW): Likewise. * sysdeps/generic/math-type-macros-float128.h: New file. * sysdeps/generic/math_private.h: Include bits/floatn.h and math_private_calls.h for _Float128. (__isinff128): New inline implementation used when GCC < 7.0, since in this case __builtin_isinf_sign is broken. (fabsf128): New inline implementation that calls the builtin. (__EXPR_FLT128): New macro. (min_of_type): Optionally include _Float128 types too. * sysdeps/generic/math_private_calls.h (__kernel_sincos): Declare for _Float128. (__kernel_rem_pio2): Likewise. * sysdeps/ieee754/ldbl-opt/s_sin.c: (__DECL_SIMD_sincos_disablef128): New macro.
