+	undefined weak symbols for all relocs.
+	(elf32_hppa_size_of_stub): Adjust calculation by 8 since branch
+	offsets are relative to one past the delay slot.

+	unsigned.

+	string, and then don't free our copy.
+	(elf32_hppa_build_one_stub): Make insn unsigned int.
+
+	* libhppa.h (bfd_hppa_insn2fmt): 22 bit branches are only

+	(elf32_hppa_relocate_section): ...to here.  Return correct error
+	message for non-handled relocs.
+	(elf32_hppa_size_of_stub): Correctly test branch range.  Previous
+	wrong test was -0x3ffff to +0x40000.
+
+	* elf-hppa.h (elf_hppa_final_link_relocate): R_PARISC_DIR17R,
+	R_PARISC_DIR17F, and R_PARISC_DIR21L are for absolute branches;
+	Handle them as such.

+
+	* libhppa.h (GET_FIELD, GET_BIT, MASK, CATENATE, ELEVEN): Delete.
+	(assemble_3, assemble_6, assemble_12, assemble_16, assemble_16a,
+	assemble_17, assemble_21): Delete.
+	Supply defines for all 64 possible opcodes.
+	(bfd_hppa_insn2fmt): Add bfd argument, and use to select wide mode
+	formats.  Handle COMICLR.
+	(hppa_rebuild_insn): Delete bfd argument.  Handle formats 10, -11,
+	-10, -16, 16, 22.
+
+	* elf32-hppa.c (hppa_elf_relocate_insn): Complete rewrite.
+	(elf32_hppa_bfd_final_link_relocate): Major rewrite.
+	(elf32_hppa_build_one_stub): Modify hppa_elf_relocate_insn calls
+	to suit.
+	(elf32_hppa_size_stubs): Don't free stub_name twice.  Read in all
+	the local syms - did this code get deleted accidentally?  Ignore
+	undefined and undefweak syms.
+
+	* elf-hppa.h (elf_hppa_final_link): Move hppa_info to outermost
+	block.  Use it instead of elf64_hppa_hash_table (info).
+	(elf_hppa_final_link_relocate): Use hppa_info instead of
+	elf64_hppa_hash_table (info).
+
+	* libhppa.h (re_assemble_3, re_assemble_12, re_assemble_16,
+	re_assemble_17, re_assemble_21, re_assemble_22): Don't mask insn.
+	(hppa_rebuild_insn): Mask immediate bits here instead.
+	* elf-hppa.h (elf_hppa_relocate_insn): Mask here too.

 	* section.c (struct sec): Add id field.  Tidy comment formatting.
