Update.
* sysdeps/sparc/sparc64/add_n.S: Avoid using %g2, %g3, %g7 registers as much as possible. Declare them using .register pseudo-op if they are still used. * sysdeps/sparc/sparc64/lshift.S: Likewise. * sysdeps/sparc/sparc64/memchr.S: Likewise. * sysdeps/sparc/sparc64/memcmp.S: Likewise. * sysdeps/sparc/sparc64/memcpy.S: Likewise. * sysdeps/sparc/sparc64/memset.S: Likewise. * sysdeps/sparc/sparc64/rawmemchr.S: Likewise. * sysdeps/sparc/sparc64/rshift.S: Likewise. * sysdeps/sparc/sparc64/stpcpy.S: Likewise. * sysdeps/sparc/sparc64/stpncpy.S: Likewise. * sysdeps/sparc/sparc64/strcat.S: Likewise. * sysdeps/sparc/sparc64/strchr.S: Likewise. * sysdeps/sparc/sparc64/strcmp.S: Likewise. * sysdeps/sparc/sparc64/strcpy.S: Likewise. * sysdeps/sparc/sparc64/strcspn.S: Likewise. * sysdeps/sparc/sparc64/strlen.S: Likewise. * sysdeps/sparc/sparc64/strncmp.S: Likewise. * sysdeps/sparc/sparc64/strncpy.S: Likewise. * sysdeps/sparc/sparc64/strpbrk.S: Likewise. * sysdeps/sparc/sparc64/strspn.S: Likewise. * sysdeps/sparc/sparc64/sub_n.S: Likewise. * sysdeps/sparc/sparc64/dl-machine.h: Likewise.
