From e240cf0e0e47436c1beb0e95f78c03f3774a4533 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Fri, 13 Oct 2017 15:49:25 -0300 Subject: sparc: refactor sparc32 fabs{f} selector to C This patch refactors the sparc32 ifunc selector to a C implementation. Also, the generic symbol is moved to its own implementation file s_fabs{f}-generic.S). Checked on sparc64-linux-gnu and sparcv9-linux-gnu. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile (libm-sysdep_routines): Add s_fabsf-generic and s_fabs-generic. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fabs-generic.S: New file. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fabs.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fabsf-generic.S: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fabsf.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fabs.S: Remove file. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fabsf.S: Likewise.
