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-coff.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,

2368ec638a * config/obj-coffbfd.c (fixup_segment): If TC_M88K, don't adjust
by md_pcrel_from if we are relocating against a symbol (we still
	need md_pcrel_from for a PC relative relocation within the same

	function.
	(cons_fix_new_hppa): New function to emit an HPPA fixup, rather
	than special case in emit_expr function.
	* config/tc-hppa.h (TC_PARSE_CONS_EXPRESSION, TC_CONS_FIX_NEW):
