From d8f619b393a230497d201398e184e3b384a263d3 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Tue, 3 Oct 2017 23:46:23 +0000 Subject: Use libm_alias_double for dbl-64 modf. This patch makes dbl-64 modf use libm_alias_double. Both the dbl-64 and dbl-64/wordsize-64 versions are changed, and the ldbl-opt version is changed to define the libc compat symbol only. Because of multiarch wrappers, the changed implementations are made not to define aliases at all if __modf is defined as a macro, as with other functions, so avoiding duplicate compat symbols while allowing those wrappers to be simplified. Tested for x86_64, and verified with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/ieee754/dbl-64/s_modf.c: Include . (modf): Define using libm_alias_double, only if [!__modf]. * sysdeps/ieee754/dbl-64/wordsize-64/s_modf.c: Include . (modf): Define using libm_alias_double, only if [!__modf]. * sysdeps/ieee754/ldbl-opt/s_modf.c (modfl): Only define libc compat symbol here. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_modf-ppc32.c (weak_alias): Do not undefine and redefine. (strong_alias): Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_modf-ppc64.c (weak_alias): Likewise. (strong_alias): Likewise. --- sysdeps/ieee754/dbl-64/s_modf.c | 7 +++---- sysdeps/ieee754/dbl-64/wordsize-64/s_modf.c | 7 +++---- sysdeps/ieee754/ldbl-opt/s_modf.c | 6 +----- sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_modf-ppc32.c | 5 ----- sysdeps/powerpc/powerpc64/fpu/multiarch/s_modf-ppc64.c | 5 ----- 5 files changed, 7 insertions(+), 23 deletions(-) (limited to 'sysdeps') diff --git a/sysdeps/ieee754/dbl-64/s_modf.c b/sysdeps/ieee754/dbl-64/s_modf.c index 0cad7b1..722511c 100644 --- a/sysdeps/ieee754/dbl-64/s_modf.c +++ b/sysdeps/ieee754/dbl-64/s_modf.c @@ -21,6 +21,7 @@ #include #include +#include static const double one = 1.0; @@ -79,8 +80,6 @@ __modf (double x, double *iptr) } } } -weak_alias (__modf, modf) -#ifdef NO_LONG_DOUBLE -strong_alias (__modf, __modfl) -weak_alias (__modf, modfl) +#ifndef __modf +libm_alias_double (__modf, modf) #endif diff --git a/sysdeps/ieee754/dbl-64/wordsize-64/s_modf.c b/sysdeps/ieee754/dbl-64/wordsize-64/s_modf.c index c309e56..8d14e78 100644 --- a/sysdeps/ieee754/dbl-64/wordsize-64/s_modf.c +++ b/sysdeps/ieee754/dbl-64/wordsize-64/s_modf.c @@ -22,6 +22,7 @@ #include #include +#include #include static const double one = 1.0; @@ -59,8 +60,6 @@ __modf(double x, double *iptr) return x; } } -weak_alias (__modf, modf) -#ifdef NO_LONG_DOUBLE -strong_alias (__modf, __modfl) -weak_alias (__modf, modfl) +#ifndef __modf +libm_alias_double (__modf, modf) #endif diff --git a/sysdeps/ieee754/ldbl-opt/s_modf.c b/sysdeps/ieee754/ldbl-opt/s_modf.c index 93acb43..268a728 100644 --- a/sysdeps/ieee754/ldbl-opt/s_modf.c +++ b/sysdeps/ieee754/ldbl-opt/s_modf.c @@ -1,9 +1,5 @@ #include #include -#if IS_IN (libm) -# if LONG_DOUBLE_COMPAT(libm, GLIBC_2_0) -compat_symbol (libm, __modf, modfl, GLIBC_2_0); -# endif -#elif LONG_DOUBLE_COMPAT(libc, GLIBC_2_0) +#if LONG_DOUBLE_COMPAT (libc, GLIBC_2_0) compat_symbol (libc, __modf, modfl, GLIBC_2_0); #endif diff --git a/sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_modf-ppc32.c b/sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_modf-ppc32.c index 6561fdf..554dc99 100644 --- a/sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_modf-ppc32.c +++ b/sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_modf-ppc32.c @@ -19,11 +19,6 @@ #include #include -#undef weak_alias -#define weak_alias(a,b) -#undef strong_alias -#define strong_alias(a,b) - #define __modf __modf_ppc32 #include diff --git a/sysdeps/powerpc/powerpc64/fpu/multiarch/s_modf-ppc64.c b/sysdeps/powerpc/powerpc64/fpu/multiarch/s_modf-ppc64.c index 43318ee..7b5656d 100644 --- a/sysdeps/powerpc/powerpc64/fpu/multiarch/s_modf-ppc64.c +++ b/sysdeps/powerpc/powerpc64/fpu/multiarch/s_modf-ppc64.c @@ -19,11 +19,6 @@ #include #include -#undef weak_alias -#define weak_alias(a,b) -#undef strong_alias -#define strong_alias(a,b) - #define __modf __modf_ppc64 #include -- cgit v1.1
