From 26007a2f689c94477ce9a00986613ccede052388 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 6 Dec 2017 22:14:09 +0000 Subject: [PATCH] Support _Float32 in libm_alias_float. This patch makes the libm_alias_float macro support creating _Float32 aliases, in preparation for enabling glibc support for that type. Tested for x86_64; also tested with build-many-glibcs.py in conjunction with other _Float32 changes. * sysdeps/generic/libm-alias-float.h: Include . [__HAVE_FLOAT32 && !__HAVE_DISTINCT_FLOAT32] (libm_alias_float_other_r): Create f32 alias. (libm_alias_float_r): Use semicolon before call to libm_alias_float_other_r. --- ChangeLog | 6 ++++++ sysdeps/generic/libm-alias-float.h | 11 +++++++++-- 2 files changed, 15 insertions(+), 2 deletions(-) diff --git a/ChangeLog b/ChangeLog index efe8ac589c..1627f78a96 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,11 @@ 2017-12-06 Joseph Myers + * sysdeps/generic/libm-alias-float.h: Include . + [__HAVE_FLOAT32 && !__HAVE_DISTINCT_FLOAT32] + (libm_alias_float_other_r): Create f32 alias. + (libm_alias_float_r): Use semicolon before call to + libm_alias_float_other_r. + * sysdeps/ia64/fpu/e_exp2f.S (__exp2f): Use exp2 not __exp2 as second argument to libm_alias_float_other. * sysdeps/ia64/fpu/e_log2f.S (__log2f): Use log2 not __log2 as diff --git a/sysdeps/generic/libm-alias-float.h b/sysdeps/generic/libm-alias-float.h index 11bd472a53..b4a5f73ed9 100644 --- a/sysdeps/generic/libm-alias-float.h +++ b/sysdeps/generic/libm-alias-float.h @@ -19,11 +19,18 @@ #ifndef _LIBM_ALIAS_FLOAT_H #define _LIBM_ALIAS_FLOAT_H +#include + /* Define _FloatN / _FloatNx aliases for a float libm function that has internal name FROM ## f ## R and public names TO ## suffix ## R for each suffix of a supported _FloatN / _FloatNx floating-point type with the same format as float. */ -#define libm_alias_float_other_r(from, to, r) +#if __HAVE_FLOAT32 && !__HAVE_DISTINCT_FLOAT32 +# define libm_alias_float_other_r(from, to, r) \ + weak_alias (from ## f ## r, to ## f32 ## r) +#else +# define libm_alias_float_other_r(from, to, r) +#endif /* Likewise, but without the R suffix. */ #define libm_alias_float_other(from, to) \ @@ -37,7 +44,7 @@ names (where there is one name per format, not per type) or for obsolescent functions not provided for _FloatN types. */ #define libm_alias_float_r(from, to, r) \ - weak_alias (from ## f ## r, to ## f ## r) \ + weak_alias (from ## f ## r, to ## f ## r); \ libm_alias_float_other_r (from, to, r) /* Likewise, but without the R suffix. */ -- 2.43.5
