Update.
1999-10-10 Ulrich Drepper <drepper@cygnus.com>
* sysdeps/powerpc/sysdep.h: New file.
* sysdeps/unix/powerpc/sysdep.h: New file.
* sysdeps/unix/sysv/linux/powerpc/sysdep.h: Include
sysdeps/unix/powerpc/sysdep.h, not sysdeps/unix/sysdep.h.
* sysdeps/powerpc/fpu/s_copysign.S: Use symbolic names for registers
instead of bare numbers.
* sysdeps/powerpc/fpu/s_fabs.S: Likewise.
* sysdeps/powerpc/fpu/s_fmax.S: Likewise.
* sysdeps/powerpc/fpu/s_fmin.S: Likewise.
* sysdeps/hppa/sysdep.h: New file.
