The enclosed patch corrects the relocation generated for format 1
load/store instructions under PA2.0W.  This caused a problem when
gas was used with the HP linker.  The patch now allows a 16-bit
offset with these insns.

Tested with binutils and hppa64-hp-hpux11.11 builds with no regressions.

Please install if ok.

	* elf-hppa.h (elf_hppa_reloc_final_type): Use R_PARISC_PCREL16F as
	the final type for the e_fsel selector when generating PA2.0W code.
	(elf_hppa_relocate_insn): Provide support for PA2.0W 16-bit format 1
