/* read.c - read a source file -
* 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-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. Also removed get_optional_absolute_expression; just use get_absolute_expression instead. * config/tc-ns32k.c (get_addr_mode, evaluate_expr, convert_iif, fix_new_ns32k, fix_new_ns32k_exp, cons_fix_new_ns32k): Ditto. * config/tc-ns32k.h (fix_new_ns32k prototype): Ditto. * config/tc-sh.c (parse_exp, check, insert, md_convert_frag): Ditto. * config/tc-sparc.c (md_assemble, sparc_ip, getExpression, print_insn): Ditto. * config/tc-tahoe.c (struct top, md_estimate_size_before_relax, tip_op, md_assemble): Ditto. * config/tc-vax.c (seg_of_operand, md_assemble, md_estimate_size_before_relax, md_create_long_jump): Ditto. * config/tc-z8k.c (parse_exp, check_operand, newfix): Ditto.

Use obj_format coffbfd and gas_target i386coff for target. (i[34]86-*-isc*): New host (uses sysv). * config/i386aix.mt: Removed (no longer used). * config/mh-i386aix (RANLIB): Use true rather than /bin/true. (MINUS_G): Removed. (LDFLAGS): Added, defined as -shlib. * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine. * config/te-sco386.h (LOCAL_LABEL): Don't define. (DOT_LABEL_PREFIX): Define. * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label name rather than L0\001. * read.c (s_lcomm): Make a frag in SEG_BSS rather than using local_bss_counter. * symbols.c, symbols.h (local_bss_counter): Removed. * write.c (write_object_file): bss no longer uses local_bss_counter. Pass correct data and bss size to VMS_write_object_file. * config/obj-vms.c (VMS_write_object_file): Accept bss size as argument, rather than using local_bss_counter. * config/tc-m88k.c (s_bss): Don't use local_bss_counter. * config/tc-sparc.c (s_reserve): Don't use local_bss_counter. * config/obj-coffbfd.c (had_lineno, had_reloc): Removed. (size_section): Restored sanity check. (do_relocs_for): Base section address on s_paddr rather than computing it. Adjust a29k R_IHIHALF special case to account for section paddr (used to require paddr to be zero). If there are no reclos, set s_relptr to 0. Set relocation size in object_headers. (fill_section): Always set s_vaddr here, removing ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set NOLOAD for i386 .bss, because it confuses the SVR3 native linker. Set STYP_INFO for .comment. (coff_header_append): Use object headers and H_{SET,GET}_* macros. Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER. (crawl_symbols): Handle 8 character section name correctly. Use H_{SET,GET}_* macros. (do_linenos_for): Set lineno size in object_headers. (write_object_file): Use H_{SET,GET}_* macros. Don't bother to set s_vaddr here. If string_byte_count remains 4, set it back to 0, and only write strings out if there are some. Call fill_section before do_relocs_for and do_linenos_for. (obj_coff_section): Handle optional quoted second argument giving section characteristics. (obj_coff_bss): Added to handle .bss. (obj_coff_ident): Added to handle .ident (puts string in .comment section). (obj_coff_lcomm): Put common symbols in .bss, not .data. (fixup_mdeps): Change to segment. Call frag_wane after md_convert_frag. (fixup_segment): Explicitly check S_IS_COMMON before making 386 adjustment (already happened only for common symbols, but this is clearer). * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define. * config/tc-i386.c (s_bss): Don't use if I386COFF. (md_pseudo_table): Ignore .optim and .noopt. (tc_coff_sizemachdep): New function. * config/tc-i386.h (REVERSE_SORT_RELOCS): Undef, for SVR3 compatibility. (LOCAL_LABEL): Removed definition. (DOT_LABEL_PREFIX): Defined.
