From 2f1b212e54b280a2dc05b809922ae25d8071da74 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 1 Nov 2017 17:03:58 +0000 Subject: Clean up complex.h handling of float128. This patch cleans up the way complex.h handles inclusion of bits/cmathcalls.h for float128. The inclusion was between those for the types float and long double; the patch moves it after that for long double, matching how bits/mathcalls.h and bits/math-finite.h inclusions are ordered. There is no need for the undefine and define of _Mdouble_complex_ to be conditional, since __CFLOAT128 is always defined by bits/floatn.h when _Float128 is supported, so the patch removes the unnecessary conditionals. Tested for x86_64. * math/complex.h [(__HAVE_DISTINCT_FLOAT128 || (__HAVE_FLOAT128 && !LIBC)) && __GLIBC_USE (IEC_60559_TYPES_EXT)]: Move conditional code after that for long double. Do not condition define and undefine of _Mdouble_complex_ on [__CFLOAT128]. --- math/complex.h | 28 +++++++++++++--------------- 1 file changed, 13 insertions(+), 15 deletions(-) (limited to 'math') diff --git a/math/complex.h b/math/complex.h index 43b4c7dbc3..48c2d9e6fc 100644 --- a/math/complex.h +++ b/math/complex.h @@ -114,21 +114,6 @@ __BEGIN_DECLS #undef _Mdouble_ #undef __MATH_PRECNAME -#if (__HAVE_DISTINCT_FLOAT128 || (__HAVE_FLOAT128 && !defined _LIBC)) \ - && __GLIBC_USE (IEC_60559_TYPES_EXT) -/* GCC < 7 requires extra convincing to expose a complex float128 type. */ -# ifdef __CFLOAT128 -# undef _Mdouble_complex_ -# define _Mdouble_complex_ __CFLOAT128 -# endif -# define _Mdouble_ _Float128 -# define __MATH_PRECNAME(name) name##f128 -# include -# undef _Mdouble_ -# undef __MATH_PRECNAME -# undef _Mdouble_complex_ -#endif - /* And the long double versions.
