From dbeb74ef84eeb981fff843d34c2ba341faad9791 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Fri, 13 Oct 2017 16:05:24 -0300 Subject: sparc: refactor sparc32 rint{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_rint{f}-generic.S). Checked on sparc64-linux-gnu and sparcv9-linux-gnu. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile (libm-sysdep_routines): Add s_rintf-generic and s_rint-generic. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_rint-generic.S: New file. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_rint.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_rintf-generic.S: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_rintf.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_rint.S: Remove file. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_rintf.S: Likewise.
