From dbcc7d089390f53ec90c1cbd3bea165b924a023a Mon Sep 17 00:00:00 2001 From: Wainer dos Santos Moschetta Date: Tue, 11 Apr 2017 14:18:34 -0300 Subject: [PATCH] powerpc: refactor stpcpy, stpncpy, strcpy, and strncpy IFUNC. Clean up the IFUNC implementations for powerpc in order to remove unneeded macro definitions. Tested on ppc64le with and without --disable-multi-arch flag. * sysdeps/powerpc/powerpc64/multiarch/stpcpy-power8.S: Define the implementation-specific function name and remove unneeded macros definition. * sysdeps/powerpc/powerpc64/multiarch/stpncpy-power7.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/stpncpy-power8.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/strcpy-power8.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/strncpy-power7.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/strncpy-power8.S: Likewise. * sysdeps/powerpc/powerpc64/power7/strncpy.S: Set a default function name if not defined. * sysdeps/powerpc/powerpc64/power8/strcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power8/strncpy.S: Likewise. --- ChangeLog | 15 +++++++++++++++ sysdeps/powerpc/powerpc64/multiarch/stpcpy-power8.S | 16 +--------------- sysdeps/powerpc/powerpc64/multiarch/stpncpy-power7.S | 16 +--------------- sysdeps/powerpc/powerpc64/multiarch/stpncpy-power8.S | 16 +--------------- sysdeps/powerpc/powerpc64/multiarch/strcpy-power8.S | 16 +--------------- sysdeps/powerpc/powerpc64/multiarch/strncpy-power7.S | 16 +--------------- sysdeps/powerpc/powerpc64/multiarch/strncpy-power8.S | 16 +--------------- sysdeps/powerpc/powerpc64/power7/strncpy.S | 14 +++++++++++--- sysdeps/powerpc/powerpc64/power8/strcpy.S | 14 +++++++++++--- sysdeps/powerpc/powerpc64/power8/strncpy.S | 14 +++++++++++--- 10 files changed, 54 insertions(+), 99 deletions(-) diff --git a/ChangeLog b/ChangeLog index 5df7004..d4bbc56 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,18 @@ +2017-04-11 Wainer dos Santos Moschetta + + * sysdeps/powerpc/powerpc64/multiarch/stpcpy-power8.S: Define the + implementation-specific function name and remove unneeded macros + definition. + * sysdeps/powerpc/powerpc64/multiarch/stpncpy-power7.S: Likewise. + * sysdeps/powerpc/powerpc64/multiarch/stpncpy-power8.S: Likewise. + * sysdeps/powerpc/powerpc64/multiarch/strcpy-power8.S: Likewise. + * sysdeps/powerpc/powerpc64/multiarch/strncpy-power7.S: Likewise. + * sysdeps/powerpc/powerpc64/multiarch/strncpy-power8.S: Likewise. + * sysdeps/powerpc/powerpc64/power7/strncpy.S: Set a default + function name if not defined. + * sysdeps/powerpc/powerpc64/power8/strcpy.S: Likewise. + * sysdeps/powerpc/powerpc64/power8/strncpy.S: Likewise. + 2017-04-11 Paul Clarke * elf/elf.h (AT_L1I_CACHESIZE, AT_L1I_CACHEGEOMETRY, AT_L1D_CACHESIZE, diff --git a/sysdeps/powerpc/powerpc64/multiarch/stpcpy-power8.S b/sysdeps/powerpc/powerpc64/multiarch/stpcpy-power8.S index a614b5b..9353471 100644 --- a/sysdeps/powerpc/powerpc64/multiarch/stpcpy-power8.S +++ b/sysdeps/powerpc/powerpc64/multiarch/stpcpy-power8.S @@ -18,21 +18,7 @@ #include -#undef EALIGN -#define EALIGN(name, alignt, words) \ - .section ".text";
