	2003-12-17  Alexandre Oliva  <aoliva@redhat.com>
	* elf32-frv.c (_frv_osec_readonly_p): New.
	(_frv_emit_got_relocs_plt_entries): Don't emit rofixup for
	undefweak symbol.
	(_frv_count_got_plt_entries): Adjust expected count accordingly.
	(elf32_frv_relocate_section): Likewise.  Error out if attempting
	to emit rofixups or dynamic relocs in read-only segments.  Use
	_bfd_elf_section_offset to adjust r_offsets in rofixups and
	dynamic relocations.
	2003-12-12  Alexandre Oliva  <aoliva@redhat.com>
	* elf32-frv.c (elf32_frv_relocate_section): Compute dynamic
	relocations or fixups involving merged sections correctly.  Avoid
	crash when undefined symbol is referenced by R_FRV_32 or
	R_FRV_FUNCDESC_VALUE.
	2003-12-02  Alexandre Oliva  <aoliva@redhat.com>
	* elf32-frv.c (elf32_frv_relocate_section): Add output_offset of
	input section holding local symbol to addend of R_FRV_32 or
	R_FRV_FUNCDESC_VALUE dynamic relocation.
	2003-11-27  Alexandre Oliva  <aoliva@redhat.com>
	* elf32-frv.c (elf32_frv_modify_segment_map): Add link info arg.

	for undefweak symbols.
	(elf32_frv_relocate_section): Avoid crash while computing
	relocation when linking with shared library.  Only emit rofixups

	with inter-segment relocations for relocation as a unit.
	(_frv_create_got_section): Rename .rofixup.got to .rofixup.

	shared libraries.  Emit rofixup for R_FRV_32 only if input object
	is not FDPIC.
	(_frv_create_got_section): Define _gp symbol in the rofixup
	section.
	(elf32_frv_finish_dynamic_sections): If rofixups needed but

	(_frv_emit_got_relocs_plt_entries): Generate fixups for non-PIE
	fdpic executables.  Use FRV_SYM_LOCAL more widely to simplify and
	improve some ugly conditions.
	(elf32_frv_relocate_section): Likewise.  Reject inter-segment
	relocations in fdpic.
	(_frv_create_got_section): Create .rofixup.got section.

	and FUNCDESC_VALUE, respectively.
	(elf32_frv_relocate_section): Likewise.
	(elf32_frv_check_relocs): Don't register as dynamic symbols of
	internal or hidden visibility.

	original relocation addend to look up the got relocs/plt entries
	table.  Do not call _bfd_elf_rel_local_sym.  Don't error out when
