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-bout.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, + parse_repeat_cons, get_segmented_expression, + get_known_segmented_expression, get_absolute_expression): Ditto. + * symbols.c (resolve_symbol_value, S_GET_VALUE, S_SET_VALUE): + Ditto. + * write.c (write_object_file): Ditto. + * config/obj-coff.c (obj_coff_def, obj_coff_val): Ditto. + * config/obj-coffbfd.c (obj_coff_def, obj_coff_val, + obj_coff_endef, yank_symbols): Ditto. + * config/obj-elf.c (obj_elf_stab_generic, obj_elf_size): Ditto. + * config/tc-a29k.c (md_assemble, parse_operand, machine_ip, + print_insn, md_operand): Ditto. + * config/tc-h8300.c (parse_exp, colonmod24, check_operand, + do_a_fix_imm, build_bytes): Ditto. + * config/tc-h8500.c (parse_exp, skip_colonthing, parse_reglist, + get_specific, check, insert, md_convert_frag): Ditto. + * config/tc-hppa.c (the_insn, fix_new_hppa, cons_fix_new_hppa, + md_assemble, pa_ip, getExpression, getAbsoluteExpression, + evaluateAbsolute, pa_build_unwind_subspace, pa_entry, + process_exit): Ditto. + * config/tc-hppa.h (STAB_FIXUP, is_DP_relative, is_PC_relative, + is_complex): Ditto. + * config/tc-i386.c (pe, md_assemble, i386_operand, + md_estimate_size_before_relax, md_create_long_jump): Ditto. + * config/tc-i860.c (md_assemble, getExpression, print_insn): + Ditto. + * config/tc-i960.c (parse_expr, subs, segs, md_convert_frag, + get_cdisp, mem_fmt, parse_ldconst, relax_cobr, s_sysproc, + i960_handle_align): Ditto. + * config/tc-m68k.c (struct m68k_exp, struct m68k_it, seg, op, + subs, add_fix, isvar, m68k_ip, md_assemble, md_convert_frag_1, + md_estimate_size_before_relax, md_create_long_jump, get_num): + Ditto. + * config/tc-m88k.c (md_assemble, get_imm16, get_pcr, + md_create_short_jump, md_create_long_jump): Ditto. + * config/tc-mips.c (md_assemble, append_insn, gp_reference, + macro_build, macro, my_getExpression): Ditto.
