abf434d83d (VMS_Initialized_Data_Size): Cache symbol values to reduce number of lookups
with S_GET_VALUE.  Skip debug symbols to avoid "a really nasty bug".  (From
Holger Teutsch, holger@botbso.rhein-main.de.)
(VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER field.  (Also
from Holger Teutsch.)  Watch for a would-be register mask that spans frags.

c17f46667a (Close_VMS_Object_File): Add comment pointing out some code that doesn't belong
in this file.

c999fd9fc2 * config/tc-vax.c (tc_aout_fix_to_chars): Local variable NBYTES_R_LENGTH now
const.

* config/obj-*.c, config/tc-*.c: Omit superfluous "return" statements at ends
of functions.  Don't check for null return from hash_new, since it won't return
at all if there's no memory available.  Also, check for null return from
hash_insert, rather than zero-length string, as success indicator.

4f0bccc7d8 Some more gcc lint, and:
* read.c (change_to_section): Removed.  This is now done by
	subseg_new.
	(get_stab_string_offset): Rearranged somewhat.  Create the section
	using subseg_new.  Store the string index in seg_info, rather than
	in a static variable.  Force the first string to be empty.  Use
	frag_more rather than FRAG_APPEND_1_CHAR.
	(s_stab_generic): Rewrote.
	* subsegs.h (segment_info_type): Added stabu union.
	* subsegs.c (subseg_new): Initialize stab_string_size to 0.
	* config/obj-aout.c: Don't include aout/stab_gnu.h.
	(obj_aout_stab, obj_aout_desc): Removed.
	(obj_pseudo_table): Removed desc and stabX entries.
	* config/obj-bout.c: Same changes as config/obj-aout.c.
	* config/obj-bout.h (S_SET_TYPE): Define.
	(tc_bout_fix_to_chars): Declare.
	* config/obj-coff.c (obj_coff_stab): Removed.
	(obj_pseudo_table): Removed desc and stabX entries.
	* config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define.
	* config/obj-coffbfd.c (current_stab_symbol): Removed.
	* config/obj-coffbfd.h (obj_symbol_type): Removed n_strx, n_type,
	n_other, n_desc and n_value fields.
	(S_{S,G}ET_{OFFSET,OTHER,TYPE,DESC}): Removed.
	(MAKE_STAB_SYMBOL): Removed.
	* config/obj-ecoff.c (obj_ecoff_stab): Renamed to ecoff_stab.
	Changed arguments and removed parsing code.
	(obj_pseudo_table): Removed stabX entries.
	* config/obj-ecoff.h (ecoff_stab): Declare.
	(OBJ_PROCESS_STAB): Define.
	* config/obj-elf.c: Don't include aout/stab_gnu.h.
	(obj_elf_stab, obj_elf_xstab, obj_elf_desc,
	elf_stab_symbol_string, elf_stab_symbol, obj_elf_stab_generic):
	Removed.
	(obj_pseudo_table): Removed desc, stabX and xstabs entries.
	(obj_elf_version): Use subseg_new, not bfd_make_section.  Don't
	set SEC_LOAD for .note section.
	(adjust_stab_sections): Get frag pointer from seg_info, rather
	than looking through frags.
	* config/obj-elf.h (S_{S,G}ET_{OTHER,TYPE,DESC}): Removed.

604633aeca * subsegs.c: Renamed non-BFD_ASSEMBLER subseg_new to subseg_set.
Wrote non-BFD_ASSEMBLER subseg_new.  Now subseg_new always takes a
	section name, and subseg_set always takes a segT.  Changed all
	callers as appropriate.
	* config/obj-coffbfd.c 	(change_to_section): Renamed to
	obj_coff_add_segment.  Corrected.  Made callers use subseg_new.
	* config/obj-coffbfd.h (obj_segment_name, obj_add_segment):
	Define.

Also some more gcc warning removal.

5ac34ac37e * Extensive changes to permit symbols to contain any expression
type and to delay the computation of the expression until the
	value is actually needed.  This permits setting symbols to values
	calculated based on object code size.  Expressions were changed to
	no longer be in a section, to stop the overloading of segment and
	expression type that previously occurred.

	* as.c (big_section, pass1_section, diff_section, absent_section):
	Removed.
	(expr_section): Added (used for dummy symbols which hold
	intermediate expression values).
	(perform_an_assembly_pass): Create expr_section, do not create the
	sections now removed.
	* as.h (segT): Removed SEG_ABSENT, SEG_PASS1, SEG_BIG, and
	SEG_DIFFERENCE.  Added SEG_EXPR.
	(SEG_NORMAL): Corresponding changes.
	* subsegs.c (seg_name, subsegs_begin): Changed accordingly.
	* write.c (write_object_file): Ditto.
	* config/obj-aout.c (seg_N_TYPE): Ditto.

	* config/obj-coffbfd.c (seg_N_TYPE): Ditto.
	* config/obj-vms.c (seg_N_TYPE): Ditto.

	* expr.h (operatorT): Moved in from expr.c, added some values.
	(expressionS): Added X_op field, removed X_seg field; renamed
	X_subtract_symbol to X_op_symbol.
	* expr.c: Extensive changes to assign expression types rather than
	sections and to simplify the parsing.
	* write.c (fix_new_internal): New static function.
	(fix_new): Removed sub_symbol argument.
	(fix_new_exp): New function, takes expression argument.
	* write.h: Prototype changes for fix_new and fix_new_exp.
	* cond.c (s_if): Changed accordingly.
	* read.c (s_lsym, pseudo_set, emit_expr, parse_bitfield_cons,

5868b1fe68 * Removed sy_forward and replaced it with an undefined expression
as the value of a symbol.
	* struc-symbol.h (struct symbol): Removed sy_forward field.  Added
	sy_resolved and sy_resolving single bit fields.
	* symbols.c (symbol_new): Don't initialize sy_forward field.
	(resolve_symbol_value): New function to adjust symbol value by
	fragment address, using recursion to resolve forward symbols.
	* symbols.h: Added prototype for new function.
	* read.c (pseudo_set): Set symbolP->sy_value to an undefined
	expression rather than setting symbolP->sy_forward.
	* write.c (write_object_file): Use resolve_symbol_value on
	symbols, keeping the common case (the old behaviour) inline.
	* config/obj-aout.c (obj_aout_frob_symbol): Removed sy_forward
	handling (subsumed by write.c change).
	* config/obj-coff.c, config/obj-coffbfd.c (obj_coff_val): Set
	sy_value rather than sy_forward.
	* config/obj-coffbfd.c (obj_coff_endef, yank_symbols): Check

85051959f4 * Changes to keep a full expression as the value of a symbol, not
just a longword:
	* struc-symbol.h: New field sy_value.
	* as.h: Include expr.h before struc-symbol.h.
	* expr.h: Use struct symbol rather than symbolS.
	* symbols.c (S_GET_VALUE, S_SET_VALUE): Rewrote to retrieve value
	of sy_value field; compile unconditionally, not just if
	BFD_ASSEMBLER.
	* symbols.h: Compile S_{SG}ET_VALUE prototypes unconditionally.
	* write.c (write_object_file): Set BFD symbol value to gas symbol
	value.
	* config/obj-aout.h, config/obj-bout.h, config/obj-coff.h,
	config/obj-coffbfd.h, config/obj-generic.h, config/obj-vms.h

	* config/obj-ieee.c (S_GET_VALUE, S_SET_VALUE): Removed.
	* config/obj-coff.h, obj-coffbfd.h: Rewrote several macros to use
	S_GET_VALUE rather than ost_entry.n_value.
	* config/obj-aout.c (obj_symbol_to_chars), config/obj-bout.c
	(obj_symbol_to_chars), config/obj-coff.c (obj_symbol_to_chars),
	config/obj-coffbfd.c (symbol_to_chars): Get value to write out
	using S_GET_VALUE--don't assume it is already set.
	* config/obj-ieee.c (do_symbols): Set BFD symbol value to gas
	symbol value.
	* config/obj-vms.c (various): Don't assign directly to
	S_GET_VALUE; use S_SET_VALUE instead.
