2002-10-06  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/powerpc/powerpc32/dl-machine.c (__process_machine_rela):
	Store R_PPC_UADDR32 and R_PPC_UADDR16 one byte at a time.
	Use __builtin_expect for R_PPC_ADDR24 overflow check.  Fix
	R_PPC_ADDR16, R_PPC_UADDR16 and R_PPC_ADDR14* overflow check, use
	__builtin_expect.
