than comparing S_GET_SEGMENT to undefined_section. (write_object_file): Skip symbols which were equated to an undefined or common symbol. * symbols.c (resolve_symbol_value): Use S_IS_DEFINED and S_IS_COMMON rather than comparing S_GET_SEGMENT to undefined_section. (S_GET_VALUE): Likewise. Avoid recursion problems if S_IS_DEFINED or S_IS_COMMON call S_GET_VALUE. * config/obj-aout.h (S_IS_COMMON): Define if not BFD_ASSEMBLER. * config/obj-aout.c (obj_emit_relocations): If a reloc is equated to an undefined or common symbol, convert the reloc to be against the target symbol.

1994-06-03 * as.h: Replace flagseen with separate variables.David MacKenzie1-2/+2
* as.c (parse_args): Set them. Don't accept -1 option, or -v explicitly (it's a synonym for --version). * as.c, input-scrub.c, messages.c, read.c, symbols.c, write.c, config/obj-aout.c, config/obj-aout.h, config/obj-bout.c, config/obj-bout.h, config/obj-coff.c, config/obj-coff.h, config/obj-vms.c, config/tc-hppa.c, config/tc-i386.c, config/tc-i960.c, config/tc-m68k.c, config/tc-mips.c, config/tc-vax.c: Use the new flag variables instead of flagseen. * config/tc-vax.c [OBJ_VMS]: Recognize -+, -1, -v, and document in usage.
1994-01-28* as.h: If __GNUC__ and inline are both undefined, define inline away.Ken Raeburn1-1/+1
* write.c (cvt_frag_to_fill): Don't assume that fr_var for rs_align or rs_org frags will be 1. (relax_segment): For rs_align, if fr_var is not 1, complain if required padding is not a multiple of the size of the pad pattern. (fixup_segment): Leave gp-relative relocations alone. For pcrel relocations referring to the same segment, clear fx_pcrel when clearing fx_addsy. * as.h: Adjust comments on rs_align. * write.c, config/obj-{aout,bout,coff*}.c, config/tc-sparc.c: Query the fx_done field instead of fx_addsy to see if the fixup still needs to be applied. Set fx_done and clear fx_addsy both, for now. If TC_HANDLES_FX_DONE isn't defined, assume md_apply_fix will only clear fx_addsy, and set fx_done accordingly after returning. * config/tc-sparc.h (TC_HANDLES_FX_DONE): Define. * config/obj-coff.c (dot_text_symbol, dot_data_symbol, dot_bss_symbol): Defined here, static. * config/obj-aout.c [BFD_ASSEMBLER]: Undef NO_RELOC before including aout/aout64.h. * write.c (write_object_file): If EMIT_SECTION_SYMBOLS is false, don't write out a section symbol even if it's used in a relocation; assume relocations will handle section numbers somehow. Rename "punt_it" label to "punt_it_if_unused" to reflect it's true use. (EMIT_SECTION_SYMBOLS): Default to 1. (adjust_reloc_syms): Don't create a new symbol for an absolute reference; just use the absolute section symbol. (write_relocs): Make printout of reloc values dependent on flag DEBUG3, not DEBUG2. * config/obj-aout.h (EMIT_SECTION_SYMBOLS): Define as 0. * config/obj-ecoff.h (EMIT_SECTION_SYMBOLS): Ditto.
1993-12-16* config/tc-vax.c (tc_aout_fix_to_chars): Local variable NBYTES_R_LENGTH nowKen Raeburn1-10/+4
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.
1993-09-14Some more gcc lint, and:Ian Lance Taylor1-210/+13
* 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.

(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. (SEPARATE_STAB_SECTIONS, INIT_STAB_SECTION, OBJ_PROCESS_STAB): Define. * config/obj-vms.c (obj_aout_stab): Removed. (obj_pseudo_table): Removed stabX entries. * config/obj-vms.h (S_SET_TYPE): Define.
1993-07-21 * Extensive changes to permit symbols to contain any expressionIan Lance Taylor1-4/+4

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).

(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 expression segment rather than sy_forward.

1993-07-14 * Changes to keep a full expression as the value of a symbol, notIan Lance Taylor1-1/+1
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 (S_GET_VALUE, S_SET_VALUE): Removed macro definitions. * 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.

1992-11-23Ran "indent", for GNU coding style; some code & comments still need fixup.Ken Raeburn1-385/+434
Removed some unneeded files. obj-coff.c (obj_coff_endef): Use as_warn, not fprintf. tc-m68k.c (md_assemble): 68000+68881 is okay -- could be emulating.
