From a49e56a945972186a829ca3ad7dec7fb9c923488 Mon Sep 17 00:00:00 2001 From: "Paul E. Murphy" Date: Tue, 7 Apr 2020 16:20:35 -0500 Subject: [PATCH] float128: use builtin_signbitf128 always The minimum GCC version has been raised to 6.2 for building glibc. Therefore, follow the advice inside the implementation and remove the GCC < 6 codepath. Likewise, remove the hidden_proto as all internal usages should inline now. --- include/math.h | 1 - sysdeps/ieee754/float128/s_signbitf128.c | 19 +------------------ 2 files changed, 1 insertion(+), 19 deletions(-) diff --git a/include/math.h b/include/math.h index 3979c47400..e1c2a4eb64 100644 --- a/include/math.h +++ b/include/math.h @@ -29,7 +29,6 @@ hidden_proto (__isnanl) hidden_proto (__finitef128) hidden_proto (__isinff128) hidden_proto (__isnanf128) -hidden_proto (__signbitf128) # endif # endif diff --git a/sysdeps/ieee754/float128/s_signbitf128.c b/sysdeps/ieee754/float128/s_signbitf128.c index 1fc00658f8..c2a1097db6 100644 --- a/sysdeps/ieee754/float128/s_signbitf128.c +++ b/sysdeps/ieee754/float128/s_signbitf128.c @@ -17,21 +17,4 @@ . */ #include -#include -#include - -/* Once GCC >= 6.0 is required for building glibc, this implementation can - be removed and replaced with an inclusion of ldbl-128/s_signbitl.c. */ -int -__signbitf128 (_Float128 x) -{ -#if __GNUC_PREREQ (6, 0) - return __builtin_signbit (x); -#else - int64_t e; - - GET_FLOAT128_MSW64 (e, x); - return e < 0; -#endif -} -hidden_def (__signbitf128) +#include "../ldbl-128/s_signbitl.c"
