+
+	* elf32-hppa.c:
+	(hppa_elf_build_long_branch_stub,hppa_elf_long_branch_needed_p):

+	when BFD is configured for debugging.
+
+	* elf32-hppa.c: (elf32_hppa_get_symextn_chain):  New function
+	to return a list of symbols that have non-zero argument
+	relocation bits.
+	(hppa_elf_stub_finish): Make sure stub generation is done only
+	once.
+
+	* elf32-hppa.c: (hppa_elf_stub_reloc):  New function for
+	generation relocation entries within a stub.
+	(hppa_elf_build_arg_reloc_stub): Corrections to argument
+	relocation stubs.
+
+	* elf32-hppa.c: New #define's for argument relocation types.

+	(CURRENT_STUB_OFFSET): New macro.

+	* elf32-target.h:  Support for special processing by the backend.
+	(struct elf_backend_data):  Added elf_backend_symbol_processing,

+	elf_backend_section_processing, elf_backend_section_from_shdr,
+	elf_backend_fake_sections, and
+	elf_backend_section_from_bfd_section fields.
+	* elfcode.h: (bfd_section_from_shdr): Add a check for
+	processor-specific section types.
+	(elf_fake_sections):  Add a check for processor-specific
+	section types.
+	(bfd_elf32_write_object_contents):  Add a check to see if
+	there is any final section processing to be done by the

+	(elf_section_from_bfd_section):  Add a check for
+	processor-specific section types.
+	(elf_slurp_symbol_table):  Remove reference to global_sym in the
+	elf_backend_data structure.  Replace it with a call to

+
+	* elfcode.h (elf_fake_sections): Check the correct condition for
