* config/tc-i386.c: Replace SEG_* with *_section, fix up subseg_*
calls. Deleted some unused code.
* config/obj-coff.c: Likewise.
ELF support, mostly contributed by Utah:
* config/obj-elf.c (obj_elf_section, obj_elf_stab, obj_elf_line,
obj_elf_type): Rewrite.
(obj_elf_frob_symbol, elf_stab_symbol_string, elf_stab_symbol,
obj_elf_desc, obj_elf_version, obj_symbol_new_hook, obj_elf_size):
New functions.
(obj_elf_ident): Dummy.
* config/obj-elf.h (FALSE, TRUE, S_*, tc_frob_symbol,
TARGET_SYMBOL_FIELDS): New macros.
(gdb_section): New variable decl.
* config/tc-i386.c (md_atof): Return zero, not empty string, on
success.
BFD_ASSEMBLER conditional changes:
* config/obj-coff.c (lineno_rootP, seg_N_TYPE, *_section_header):
Don't define these.
(SA_SET_SYM_ENDNDX, SA_SET_SYM_TAGNDX): New functions.
(fetch_coff_debug_section): Ditto.
(obj_coff_endef): Call fetch_coff_debug_section.
(struct line_no): New type.
(c_symbol_merge): New way for copying aux fields.
(c_dot_file_symbol): Put symbol in absolute section, and set flag
BSF_DEBUGGING.
(function_lineoff): New symbol.
(function_lineoff, text_lineno_number, our_lineno_number,
lineno_lastP): Don't define.
(c_line_new): Don't define.
(obj_emit_lineno, obj_coff_endef): Use abort calls as, uh,
placeholders, until
line-number recording gets implemented.
(obj_new_symbol_hook): New code for handling aux fields.
(add_lineno, add_linesym): New functions.
(obj_coff_ln): Call add_lineno, not c_line_new.
(obj_coff_endef): New code for handling symbol names. New lineno
code. Look for section name "*DEBUG*" for debugging section.
(align, coff_check_file_symbols, obj_coff_section,
coff_frob_file): New functions.
* config/obj-coff.h: Reordered some includes.
(BYTE_ORDERING, FILE_HEADER_MAGIC, seg_N_TYPE, N_TYPE_seg,
DEFAULT_MAGIC_NUMBER_FOR_OBJECT_FILE, AOUTHDR, AOUTHDRSIZE): Don't
define these.
(TARGET_SYMBOL_FIELDS, I960_SYM_FIELDS): New macros.
(SYM_AUXENT): New macro (for non-BFD_ASSEMBLER too) for accessing
aux entries. Most SA_* macros now use it unconditionally.
(S_*): Use `bsym' field, and access BFD private data.
(SF_*): Use `sy_flags' symbol field for most of these.
(H_*, object_headers, lineno, lineno_*P, OBJ_EMIT_LINENO): Don't
define.
(*_section_header): Don't define.
* config/tc-i386.c (md_convert_frag, md_apply_fix): Changed
interface.

* config/tc-i386.h (TARGET_ARCH, TARGET_BYTES_BIG_ENDIAN): New
macros.
* config/obj-coff.c (stack_init): Don't do assignments inside
conditions.
(obj_coff_def): Simplified handling of symbol name a bit.
(tag_insert): Name argument is now pointer to CONST.
(obj_crawl_symbol_chain): Commented out.
* config/obj-coff.h: Use PARAMS macro in prototypes.
* write.c (relax_and_size_seg) [BFD_ASSEMBLER]: Don't indirect
through frchainP pointer if it is null.
* configure.in: Warn if BFD mode is explicitly turned off but is
required by specified target.
(mips ecoff targets): Don't need to set bfd_gas here; it gets
taken care of later.
* config/obj-coffbfd.c (crawl_symbols): Don't clear sy_forward
field.
(yank_symbols): Merge symbols only if sy_forward is null.
* config/tc-m68k.h (AOUT_MACHTYPE): Don't define if already
defined.

pointer.
