bfd/

2012-02-09  H.J. Lu  <hongjiu.lu@intel.com>

	PR ld/13675
	* cpu-i386.c (bfd_arch_i386_fill): Updated to support multi byte
	nop instructions.
	(bfd_arch_i386_short_nop_fill): New.
	(bfd_arch_i386_long_nop_fill): Likewise.
	Use bfd_arch_i386_short_nop_fill in 32bit bfd_arch_info
	initializers.  Use bfd_arch_i386_long_nop_fill on 64bit
	bfd_arch_info initializers.

	* cpu-k1om.c (bfd_arch_i386_fill): Renamed to ...
	(bfd_arch_i386_short_nop_fill): This.
	Update bfd_arch_info initializers.
	* cpu-l1om.c: Likewise.
