From 4699cb8b5f25827eec50f071183a4abba04f16e5 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Tue, 3 Oct 2017 23:44:41 +0000 Subject: Use libm_alias_double for dbl-64 logb. This patch makes dbl-64 logb use libm_alias_double. Both the dbl-64 and dbl-64/wordsize-64 versions are changed, and the ldbl-opt version is removed. Because of multiarch wrappers, the changed implementations are made not to define aliases at all if __logb 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 (except on alpha where changes from using the wordsize-64 version are expected). * sysdeps/ieee754/dbl-64/s_logb.c: Include . (logb): Define using libm_alias_double, only if [!__logb]. * sysdeps/ieee754/dbl-64/wordsize-64/s_logb.c: Include . (logb): Define using libm_alias_double, only if [!__logb]. * sysdeps/ieee754/ldbl-opt/s_logb.c: Remove file. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_logb-ppc32.c (weak_alias): Do not undefine and redefine. (strong_alias): Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_logb-ppc64.c (weak_alias): Likewise. (strong_alias): Likewise. --- ChangeLog | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index b2e9efa91f..dceeb542c7 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,18 @@ +2017-10-03 Joseph Myers + + * sysdeps/ieee754/dbl-64/s_logb.c: Include . + (logb): Define using libm_alias_double, only if [!__logb]. + * sysdeps/ieee754/dbl-64/wordsize-64/s_logb.c: Include + . + (logb): Define using libm_alias_double, only if [!__logb]. + * sysdeps/ieee754/ldbl-opt/s_logb.c: Remove file. + * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_logb-ppc32.c + (weak_alias): Do not undefine and redefine. + (strong_alias): Likewise. + * sysdeps/powerpc/powerpc64/fpu/multiarch/s_logb-ppc64.c + (weak_alias): Likewise. + (strong_alias): Likewise. + 2017-10-03 H.J.
