1994-01-20* expr.c (operand): For floating point operand with unusual fp char fromKen Raeburn1-24/+19
FLT_CHARS, preserve the character. Patch from Lisa Repka.
1993-11-02 * struc-symbol.h: Add new "sy_used" field to the symbol structure.Jeff Law1-0/+8
* expr.c (operand): Set sy_used for any symbol used as an operand. (expr): Likewise for any symbol used in an expression. * config/tc-hppa.h (tc_frob_symbol): Define. Punt imported symbols which are never used and absolute symbols which local scope.
1993-10-31 * expr.c (make_expr_symbol): Delete DOT_LABEL_PREFIX codeJeff Law1-22/+29
and instead simply use the string defined by FAKE_LABEL_NAME. (operand): Likewise. * read.c (s_stab_generic): Likewise.
1993-09-10gcc lint. See ChangeLog for details. Also:Ian Lance Taylor1-25/+46
* config/obj-elf.h (S_SET_SIZE): Actually set the size.
1993-07-21 * Extensive changes to permit symbols to contain any expressionIan Lance Taylor1-430/+264
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.

1993-07-19 * expr.c (clean_up_expression): Don't cancel the subtraction ofIan Lance Taylor1-0/+1
undefined symbols. Fixes PR 2997. * read.c (s_data), config/obj-coffbfd.c (obj_coff_data): If -R, switch to text section rather than data section. Fixes PR 2971.

1992-12-30Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)Ian Lance Taylor1-5/+9
* app.c, config/tc-*.c: Don't include read.h, since it is already included by as.h. * These are based on patches from Minh Tran-le <mtranle@paris.intellicorp.com>. * configure.in (i[34]86-ibm-aix*): Accept i486 for host. 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.

* expr.c(expr): allow SEG_REGISTER in expressions. * read.c(pseudo_set): register expressions can be the source of a set. * subsegs.c (subseg_new): Now -R forces all changes to SEG_DATA to goto SEG_TEXT (if a.out) * write.c (write_object_file): If a.out don't use the old way for -R. * config/obj-a.out (s_sect): complain if the user tries to use a subsegment with a value which might interfere with out -R hackery. * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table rather than use ugly if tree. (init_regtable): insert register names into symbol table.
1992-02-26 * expr.c: If an expression is single comma, then return withSteve Chamberlain1-1/+2
SEG_ABSENT rather than an error - since the sparc front end does really strange things with things like fbge,a
1992-02-25 * as.h: include bfd.h if using many sectionsSteve Chamberlain1-4/+4
* expr.c: LOCAL_LABELS_FB had been changed to lower case - so local labels didn't work. * listing.c (list_symbol_table): don't core dump when there's no symbol there. * write.c, write.h: call fix_new with the right number of args on the H8. * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make errors nicer
1992-02-22 * app.c: MRI compatibility - allow single quote to start a string.Steve Chamberlain1-555/+696
* as.c: fix typo recently introduced. * as.h : Don't include aout/reloc.h - it's not right for COFF! * expr.c: Much rewriting, to accomodate MRI syntax for expressions. Also easier to read now. * listing.c: Put back defuns * read.c: modified to accept MRI syntax, put back listing pseudo ops so that an assembler built with NO_LISTING ignores list ops rather than pukes. * write.c, write.h: fixs - only keep a reloc type in a fix if the target machine is a SPARC or a 29K. * config/obj-aout.c: added s_sect pseudo op * config/obj-coffbfd.c: lints, set the filehdr flags right and fill in the timestamp. * config/obj-coffbfd.h: Since we don't include aout/reloc.h anymore, define all the relocs which the tc-<x> bit will use so we can translate from them to the coff types. * config/tc-a29k.c: reloc_type isn't ane enum any more * config/tc-m68k.c: Added NO_RELOC definition. Now compiles for sparc aout, 68k aout (MRI and MIT syntax), 29k coff. So far works as replacement for sparc and 68k /bin/as.
