1995-01-19Cleanup of VAX and VMS code, from Pat Rankin:Ken Raeburn1-2/+2
* config/obj-vms.c: Changed exported function names to lower case. (Changed call sites in write.c.) Declare VMS system function names used, conditional on actually being on VMS. Changed many functions that returned no useful value to now be declared to return void. Removed many unused variables. Supply missing return statements or values. Supply `default' case in switch statements. Ensure local variables get initialized. * config/tc-vax.c: Minor changes to silence "gcc -Wall". * config/obj-vms.h, config/tc-vax.h: Added some missing declarations.

* read.c (s_space): Rewrite to handle general expressions. Generate rs_space frags for non-constant values. * write.c (cvt_frag_to_fill): Treat rs_align_code and rs_space like rs_align and rs_org. Verify that fr_offset is non-negative, and force frag type to rs_fill only after assertion checks. (relax_segment): Treat rs_align_code like rs_align. Treat rs_space like rs_org in the first switch; in the second, force the operand to a constant, and use it for the growth size.
1994-12-10* write.c (write_relocs) [RELOC_EXPANSION_POSSIBLE]: Use bfd_install_relocation.Ken Raeburn1-22/+75
1994-09-29* write.c (print_fixup): Print source location on first line. Show fx_r_typeKen Raeburn1-2/+14
and fx_addsy fields.
1994-09-28(fix_new_exp): Handle O_add by creating an expression-valued symbol, andKen Raeburn1-20/+98
calling fix_new_exp recursively. (adjust_reloc_syms): If a fixup's symbol value is a sum of an undefined symbol and a constant, fold the constant into the fixup, and refer to the undefined symbol directly. Then process the fixup again from scratch. (write_object_file): Before calling adjust_reloc_syms, make a pass through the symbol list trying to resolve values. (print_fixup): New routine, for debugging. (write_relocs): Call bfd_install_relocation. Deleted various hacks for working around problems with bfd_perform_relocation.
1994-09-13* write.c (fixup_segment): Test TC_RELOC_RTSYM_LOC_FIXUP on fixup beforeKen Raeburn1-12/+76
processing same-section pcrel relocations. (TC_RELOC_RTSYM_LOC_FIXUP): Default to 1.
1994-06-03 * as.h: Replace flagseen with separate variables.David MacKenzie1-8/+14
* 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.

(chain_frchains_together): Set frags_chained.
1994-03-19* write.c (symbol_table_frozen): New variable, to be set after bfd_set_symtabKen Raeburn1-72/+110
is called. (dump_section_relocs): Note whether a symbol is a section symbol or not. (adjust_reloc_syms): For now, always supply an absolute symbol for fixups without symbols but not yet `done'. Use section_symbol to get the symbol, instead of going directly for abs_symbol. (write_relocs) [DEBUG4]: Abort if any symbol referred to by a reloc is not a section symbol and is not in the symbol table. (set_symtab): New function, broken out from write_object_file. Counts symbol table instead of relying on an earlier count. (write_object_file): Call set_symtab, but do it after potentially invoking the *_frob_file macros. Don't bother counting symbols. Call symbol_remove, instead of expanding it in place. Moved the conditionalized `object_file_size' declaration down to conditionalized block where it's used. When using the absolute symbol for a fixup without a symbol, set sy_used_in_reloc. (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get the correct symbol for the absolute section.
1994-02-18write.c (write_object_file): Removed register declarations.Ken Raeburn1-9/+13

1994-02-05 Changed relocs to be based on subsegments (when BFD_ASSEMBLER).Ian Lance Taylor1-51/+49
* subsegs.h (struct frchain): If BFD_ASSEMBLER, added new fields fix_root and fix_tail. (segment_info_type): If BFD_ASSEMBLER, don't define fix_tail field. * write.c (fix_new_internal): If BFD_ASSEMBLER, set fix_rootP and fix_tailP based on frchain_now, not seg_info (now_seg). (chain_frchains_together_1): Chain the subsegment relocs together. * subsegs.c (subseg_change): Don't clear fix_tail field. (subseg_get): Likewise. * literal.c (add_to_literal_pool): Look through the relocs via frchain_now, not seginfo. * write.c (write_object_file): Simplified usage of obj_frob_symbol and tc_frob_symbol. Always call both if the symbol is going to be output. * write.c (relax_segment): Use %ld rather than %d when printing fragP->fr_var, and cast it to long.
1994-01-30* write.c (write_object_file): If tc_frob_file is defined, call itKen Raeburn1-0/+4
just before calling obj_frob_file. * config/tc-alpha.c (alpha_gp_value): Renamed from gp_value (refs changed), made non-static. (getExpression): Return void. (select_gp_value): Abort if gp_value is non-zero. Delete call to non-existent bfd_set_gp_value. (alpha_validate_fix): Function deleted. (alpha_frob_symbol): Function deleted.

1994-01-28* as.h: If __GNUC__ and inline are both undefined, define inline away.Ken Raeburn1-44/+82
* 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.
1993-12-20* write.c (adjust_reloc_syms) [RELOC_REQUIRES_SYMBOL]: If no symbol is presentKen Raeburn1-2/+21
(i.e., relocation against absolute), create a phony local symbol, and use it in the reloc. (fixup_segment): When adjusting a reloc with an absolute symbol, have TC_FORCE_RELOCATION control clearing add_symbolP too. * config/tc-sparc.h (RELOC_REQUIRES_SYMBOL): Define.
1993-12-20* as.c (main): Only invoke md_end if it's defined as a macro.Ken Raeburn1-16/+1

1993-11-30 * write.c (TC_FORCE_RELOCATION): Provide a default definition.Jeff Law1-54/+71

Remove #ifndef TC_HPPA hack. * config/tc-hppa.h (TC_FORCE_RELOCATION): Define. * config/tc-hppa.c (md_apply_fix_1): Never change fx_addsy to be NULL. Only fixup_segment is supposed to do that. (hppa_force_relocation): New function.
1993-11-18Get ECOFF gas to work again after this morning's checkins.Ian Lance Taylor1-1/+1
1993-11-17 * write.c (is_dnrange): Do not define if md_relax_frag is defined.Ian Lance Taylor1-34/+38
(relax_segment): If md_relax_frag is defined, use it to handle a frag of type rs_machine_dependent rather than looking through md_relax_table. * write.c (relax_and_size_seg): Don't set SEC_HAS_CONTENTS for a bss section. Set SEC_RELOC if there are any relocations, even for a zero size section. * write.c (write_relocs): In RELOC_EXPANSION_POSSIBLE case, based data offset on reloc[0]->address rather than reloc[j]->address, so that multiple relocs can affect different memory locations. * write.c (chain_frchains_together, relax_and_size_seg, adjust_reloc_syms, write_relocs): Make third argument PTR, not char *, to match definition of bfd_map_over_sections.
1993-11-05 * write.c (chain_frchains_together): Update pointer to lastJeff Law1-3/+11
frag for a segment in the seginfo structure.
1993-11-02 * Add support for marker type relocations. These mark areasJeff Law1-4/+3
of interest to the linker. ENTRY/EXIT relocations for SOM are an example of marker relocations. * write.c (write_relocs): Instead of assuming size of a relocation is 4 bytes, pick up the size from relocation itself. (fixup_segment): Do not complain that a value is too small for marker relocations.
