+
+ * 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.
