mode selector if needed.

be either 0 or 2 (no static link or static link required). Always
assume no static link.

Avoid dereferencing a NULL fx_addsy.
(hppa_force_relocation): Avoid dereferencing a NULL fx_addsy.
- sparc[lite]-coff as well as sparc-lynx
- producing coff (including debug info) under BFD_ASSEMBLER option
- cleanup of cpu-specific code in non-cpu-specific files
(especially write.c)
- providing common code to avoid duplication in cpu-specific files
(specifically, md_number_to_chars)
- stylistic changes & misc cleanup

(sy_tc, sy_obj): Define so that the fields look like they used to, until all
references get changed.
* write.c (fixup_segment): Lots of variables no longer register. Reordered
some code for easier reading.
* config/obj-coff.c (obj_coff_dim): dim_index no longer register. Deleted
superfluous return statement.

tag_init, tag_insert): Deleted superfluous return statement.
(align, obj_coff_section): Deleted debugging printfs.

sufficient.
* config/tc-sparc.c (print_insn): Array Reloc is now const, and points to
const.

a fixup. Call TC_ADJUST_RELOC_COUNT just before returning. Remove some
i960-coff-specific code.
(TC_ADJUST_RELOC_COUNT): Default to doing nothing.
* config/tc-i960.h (TC_ADJUST_RELOC_COUNT) [OBJ_COFF]: Define.
(i960_validate_fix): Declare.
(TC_VALIDATE_FIX): Define.

* config/obj-coff.c: Rearranged code for handling line number data.
(line_fsym): Renamed from function_lineoff in BFD_ASSEMBLER case, since the
usage is different from non-BFD_ASSEMBLER case.
(in_function, clear_function, set_function): New macros, to combine some of the
functionality implemented in differnet ways in BFD_ASSEMBLER and non-... code.
Used in other functions that used to check function_lineoff &c.
(obj_emit_lineno): Split into two copies, one for BFD_ASSEMBLER, one for not.
Non-BFD_ASSEMBLER version now has temporary variable to contain char* pointer
pointed to by char** argument. Always follow CROSS_COMPILE code; easier to
read that way.
(obj_coff_ln): Don't call add_lineno or c_line_new if appline is set.
(obj_coff_endef) [BFD_ASSEMBLER]: Don't do anything special for ".bf", it's
been done elsewhere.

particular symbol, to make the sort more stable.
(nlm_write_object_contents): Cast the arguments to qsort. Get the
value of a debugging symbol the same way we get the value of a
normal symbol.
* nlm32-alpha.c: Various changes. Write out GP and .lita relocs.
Set no_uninitialized_data to true.
* nlm32-i386.c (nlm32_i386_backend), nlm32-sparc.c

just called old nlm_i386_write_reloc.
(nlm_i386_write_external): Renamed from nlm_i386_write_externals.
Declared. Changed second argument from bfd_vma to bfd_size_type.

* nlm32-sparc.c (nlm_sparc_mangle_relocs): Removed unused,
ifdeffed out code.

to bfd_size_type.

* nlmcode.h: Removed some unused code.
(nlm_object_p): Don't destroy tdata pointer. Call

NLM_HIBIT.
(nlm_compute_section_file_positions): Account for
optional_prefix_size.
(nlm_write_object_contents): Account for optional_prefix_size.
Removed useless variable write_reloc_func. Changed declaration
and call of write_import_func. Call write_prefix_func if it
exists. Removed unused variables len and temp. Call
get_public_offset_func if it exists rather than setting NLM_HIBIT.
different CPU specs that use the same ld_target values.
