Also, the generic symbol is moved to its own implementation file submul_1-generic.S). Checked on sparc64-linux-gnu and sparcv9-linux-gnu. * sysdeps/sparc/sparc64/multiarch/Makefile (sysdep_routines): Add submul_1-generic. * sysdeps/sparc/sparc64/multiarch/submul_1-generic.S: New file. * sysdeps/sparc/sparc64/multiarch/submul_1.c: Likewise. * sysdeps/sparc/sparc64/multiarch/submul_1.S: Remove file.
