From 1c051a9b09339c26a9ada5aeff1b184654cafaf2 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Fri, 13 Oct 2017 16:11:33 -0300 Subject: sparc: refactor sparc32 nearbyint{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_nearbyint{f}-generic.S). Checked on sparc64-linux-gnu and sparcv9-linux-gnu. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile (libm-sysdep_routines): Add s_nearbyintf-generic and s_nearbyint-generic. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyint-generic.S: New file. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyint.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyintf-generic.S: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyintf.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyint.S: Remove file. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyintf.S: Likewise.
