From 69056564042f3d43012814f92230d2c3f9ab7d7c Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Tue, 3 Oct 2017 10:58:29 -0300 Subject: sparc: Implement memset/bzero ifunc selection in C This patch refactor the SPARC64 ifunc selector to a C implementation. No functional change is expected, including ifunc resolution rules. Checked on sparc64-linux-gnu, sparcv9-linux-gnu and x86_64-linux-gnu. * sysdeps/sparc/sparc32/sparcv9/multiarch/Makefile [$(subdir) = string] (sysdep_routines): Add memset-ultra1. * sysdeps/sparc/sparc64/multiarch/Makefile [$(subdir) = string] (sysdep_routines): Add memset-ultra1. * sysdeps/sparc/sparc32/sparcv9/multiarch/memset-ultra1.S: New file. * sysdeps/sparc/sparc32/sparcv9/multiarch/memset.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/multiarch/bzero.c: Likewise. * sysdeps/sparc/sparc64/multiarch/ifunc-memset.h: Likewise. * sysdeps/sparc/sparc64/multiarch/memset-ultra1.S: Likewise. * sysdeps/sparc/sparc64/multiarch/memset.c: Likewise. * sysdeps/sparc/sparc64/multiarch/bzero.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/multiarch/memset.S: Remove file. * sysdeps/sparc/sparc64/multiarch/memset.S: Likewise.
