From 5d75b75fb772556873f3b720e63a740074ff4c40 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Fri, 16 Mar 2018 18:36:53 +0000 Subject: Remove sysdeps/x86/fpu/bits/mathinline.h __finite inline. Continuing the removals of inline functions from the x86 bits/mathinline.h, this patch removes an inline of __finite (which was not actually architecture-specific at all beyond its endianness-dependence). This inline is not normally used with GCC 4.4 or later, because isfinite now uses __builtin_isfinite except for -fsignaling-nans. Allowing __builtin_isfinite etc. to work properly even for -fsignaling-nans, by implementing versions of those built-in functions that use integer arithmetic in GCC, is (a patch was committed but had to be reverted because it caused problems, and that patch didn't address all formats for all architectures, only some, so by itself would not have been sufficient to allow glibc to use __builtin_isfinite unconditionally for new-enough GCC). Tested for x86_64 and x86. * sysdeps/x86/fpu/bits/mathinline.h [__USE_MISC] (__finite): Remove inline function. --- ChangeLog | 3 +++ sysdeps/x86/fpu/bits/mathinline.h | 13 ------------- 2 files changed, 3 insertions(+), 13 deletions(-) diff --git a/ChangeLog b/ChangeLog index 78cb497143..c2468c8cd8 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,8 @@ 2018-03-16 Joseph Myers + * sysdeps/x86/fpu/bits/mathinline.h [__USE_MISC] (__finite): + Remove inline function. + * sysdeps/i386/fpu/libm-test-ulps: Update. * sysdeps/i386/i686/fpu/multiarch/libm-test-ulps: Likewise. diff --git a/sysdeps/x86/fpu/bits/mathinline.h b/sysdeps/x86/fpu/bits/mathinline.h index d7fa3847eb..91ece8dfb8 100644 --- a/sysdeps/x86/fpu/bits/mathinline.h +++ b/sysdeps/x86/fpu/bits/mathinline.h @@ -306,19 +306,6 @@ __inline_mathcodeNP2 (hypot, __x, __y, # endif -# ifdef __USE_MISC - -/* This function is used in the `isfinite' macro. */ -__MATH_INLINE int -__NTH (__finite (double __x)) -{ - return (__extension__ - (((((union { double __d; int __i[2]; }) {__d: __x}).__i[1] - | 0x800fffffu) + 1) >> 31)); -} - -# endif /* __USE_MISC */ - /* Undefine some of the large macros which are not used anymore. */ # ifdef __FAST_MATH__ # undef __expm1_code -- cgit 1.4.1
