This introduces the machine-dependent bits/floatn.h to control the inclusion of _Float128 ABI. * bits/floatn.h: New file. * bits/huge_val_flt128.h: Likewise. * bits/libm-simd-decl-stubs.h (__DECL_SIMD_cosf128): New macro. (__DECL_SIMD_sinf128): Likewise. (__DECL_SIMD_sincosf128): Likewise. (__DECL_SIMD_logf128): Likewise. (__DECL_SIMD_expf128): Likewise. (__DECL_SIMD_powf128): Likewise. * math/Makefile (headers): Install bits/floatn.h and bits/huge_val_flt128.h. * math/bits/cmathcalls.h (_Mdouble_complex_): Only define if not defined. * math/bits/mathcalls.h (pow10, isinf, finite, drem, significand) (isnan, gamma, nexttoward, scalb): Only define if not __MATH_DECLARING_FLOATN. (nextdown, nextup, llogb, roundeven, fromfp, ufromfp, fromfpx) (ufromfpx, fmaxmag, fminmag, totalorder, totalordermag) (canonicalize, getpayload, setpayload, setpayloadsig): Declare for _FloatN even if __STDC_WANT_IEC_60559_BFP_EXT__ is not defined. * math/complex.h: Include bits/libc-header-start.h and bits/floatn.h. Include bits/cmathcalls.h to get the declarations of _Float128 versions of complex functions. [__HAVE_FLOAT128 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (CMPLXF128): Define macro. * math/math.h: Include bits/floatn.h and bits/huge_val_flt128.h. Include bits/mathcalls-helper-functions.h and bits/mathcalls.h to get the declarations of _Float128 versions of math functions. (__MATH_DECLARING_FLOATN): New macro to control declaration of _FloatN types. [__GNUC_PREREQ (6,0)] (signbit): Since GCC 6.0, __builtin_signbit is type-generic, so use it without __MATH_TG. [__HAVE_DISTINCT_FLOAT128] (isinf): This builtin is broken for _Float128 type on GCC < 7.0. Explicitly call __isinff128 for _Float128 type and GCC < 7.0, otherwise use the builtin. [__HAVE_FLOAT128 && defined __USE_GNU] (M_Ef128, M_LOG2Ef128) (M_LOG10Ef128, M_LN2f128, M_LN10f128, M_PIf128, M_PI_2f128) (M_PI_4f128, M_1_PIf128, M_2_PIf128, M_SQRT2f128, M_SQRT1_2f128): New _GNU_SOURCE enabled macros.
