From 39037048502d52ab6422c18f2d178d6228d2c7b9 Mon Sep 17 00:00:00 2001 From: Anton Blanchard via Libc-alpha Date: Thu, 14 May 2020 09:00:26 +1000 Subject: powerpc: Optimized strcpy for POWER9 This version uses VSX store vector with length instructions and is significantly faster on small strings and relatively unaligned large strings, compared to the POWER8 version. A few examples: __strcpy_power9 __strcpy_power8 Length 16, alignments in bytes 0/ 0: 2.52454 4.62695 Length 412, alignments in bytes 4/ 0: 11.6 22.9185 --- sysdeps/powerpc/powerpc64/multiarch/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'sysdeps/powerpc/powerpc64/multiarch/Makefile') diff --git a/sysdeps/powerpc/powerpc64/multiarch/Makefile b/sysdeps/powerpc/powerpc64/multiarch/Makefile index ea936bf9ed..db11345053 100644 --- a/sysdeps/powerpc/powerpc64/multiarch/Makefile +++ b/sysdeps/powerpc/powerpc64/multiarch/Makefile @@ -32,7 +32,7 @@ sysdep_routines += memcpy-power8-cached memcpy-power7 memcpy-a2 memcpy-power6 \ strncase-power8 ifneq (,$(filter %le,$(config-machine))) -sysdep_routines += strcmp-power9 strncmp-power9 +sysdep_routines += strcmp-power9 strncmp-power9 strcpy-power9 endif CFLAGS-strncase-power7.c += -mcpu=power7 -funroll-loops CFLAGS-strncase_l-power7.c += -mcpu=power7 -funroll-loops -- cgit 1.4.1
