3 * section.c (bfd_get_section_contents): Since this function reads
4 unrelocated contents, the section's raw size is always the one to
5 use for bounds checking.

8 link_order size field against cooked size, not raw size, of input
11 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just

14 current offset in the section plus the number of bytes of padding
15 that will actually be retained.
16 (b_out_relax_section): If a section contains no relocations, don't
17 bother processing them.
18 (b_out_get_relocated_section_contents): Set reloc_done. Assert

22 that reloc->addend falls between the current source offset and the
23 raw size of the input section.
25 * config.bfd: Support i960 vxworks versions > 5.0 with coff, not
26 bout. Default with no version number is still bout. Support
27 explicit i960-coff target too.
29 * bout.c: Changed some indentation, deleted trailing whitespace,
30 fixed some comments, removed some "#if 1" lines.
31 (output_addr): New macro.
32 (calljx_callback, callj_callback, get_value, abs32code, aligncode,

37 * som.c (som_bfd_prep_for_ar_write): Iterate through the SOM
38 symbols, not the BFD symbols.
39 (som_bfd_ar_write_symbol_stuff): Likewise.
43 * som.c (som_slurp_symbol_table): Do not die if a BFD doesn't
46 * Finish basic read-write support for SOM archive libraries. Bugs
47 surely remain as this hasn't been tested all that much.

49 (struct som_misc_symbol_info): New structure to hold info necessary
50 to build both normal and library symbol tables.

52 to build both normal and library symbol tables.

465 value into a pointer to a symbol and set fix_value.

475 bfd_coff_symname_in_debug returns true, don't put symbol name in

477 debug_string_size is not 0, check that it matches the size of the

532 definition of SELECT_RELOC accordingly.
536 * coffcode.h (bfd_coff_backend_data): Added new arguments to
537 _bfd_coff_swap_aux_in and _bfd_coff_swap_aux_out: aux index number

541 * libcoff.h: Rebuilt.
542 * coffswap.h (coff_swap_aux_in, coff_swap_aux_out): Accept new
543 arguments. If RS6000COFF_C, only treat C_EXT and C_HIDEXT
544 specially if this is the last aux entry.
545 * coffgen.c (coff_write_symbol, coff_get_normalized_symtab): Pass
546 new arguments to swap_aux functions.
550 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
551 (only testing for m68k and vax at the moment); do verify that the
552 preprocessor didn't trash the arch name inside the string version.
553 Don't print out "pagesize =" line that prevents output from
554 compiling. Derive BYTES_IN_WORD and ARCH values from sizeof

582 * som.c, som.h (bfd_som_set_section_attributes,
583 bfd_som_set_subsection_attributes): Change parameters from char
584 to int. Following a prototype with an old-style function definition
585 in the presence of widened parameters is a GCC-ism not supported
586 by the HP compiler in ANSI mode.
590 * reloc.c (bfd_get_reloc_size): Size of type -2 is 4 bytes, not 2.
592 * hp300hpux.c (MY(write_object_contents)): Write out the symbols

601 bfd_xmalloc_by_size_t.
602 * opncls.c (_bfd_new_bfd): Avoid ANSI C prototype.

638 entries in default_vector.
639 * bfd-in2.h: Regenerated.
643 * coff-alpha.c (alpha_ecoff_object_p): New function. Set size of
644 .pdata section based on lnnoptr field, not section header.
645 (alpha_relocate_section): Don't bother to check if r_symndx >= 0,
646 since it is unsigned.
647 (ecoffalpha_little_vec): Use alpha_ecoff_object_p rather than
649 * ecoff.c (ecoff_new_section_hook): Set alignment_power field of
651 (ecoff_compute_section_file_positions): Save the size of the

655 calling ecoff_compute_section_file_positions.

658 header from the vstamp of the symbolic header.

660 vstamp used by the first object file in the link.

665 for a created common section.
666 (_bfd_generic_link_add_one_symbol): Likewise.
668 * elfcode.h (swap_out_syms): Use elf_section_from_bfd_section to
669 get the index of a common section, rather than always using
670 SHN_COMMON (MIPS has multiple common sections).

674 * bfd/aoutx.h (aout_link_input_section_std,
675 aout_link_input_section_ext): Pass additional arguments to
676 reloc_overflow callback.
677 * coff-alpha.c (alpha_ecoff_get_relocated_section_contents,

691 use get_value to get the symbol value and check for undefined
693 * reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
694 undefined, look it up in the linker hash table.
696 * aoutx.h (translate_symbol_table): The string index 0 has a
697 special meaning for normal symbols, but not for dynamic symbols.

721 The sparc (and possibly other?) NLM format requires a different
722 way to write exports, so add a write_export field to the backend
723 data (and set it to NULL for everything but the sparc).
727 * sunos.c (MY(read_dynamic_relocs)): Compare info->dynrel with NULL,
728 not (struct external_nlist *) NULL. info->dynrel is a PTR, not
729 a struct external_nlist *.

785 * config/alphaosf.mh (HDEFINES): Don't define HOST_64_BIT here;
786 that's dealt with elsewhere.
787 * hosts/alphaosf.h (sprintf_vma, fprintf_vma): New macros.
788 (uint64_typeHIGH, uint64_typeLOW): Comment with HOST_64_BIT so
789 they get copied to bfd.h.

792 types. Reorganized some of the existing ones.
793 * coff-alpha.c (alpha_howto_table): Construct 64-bit negative one

884 * ecofflink.c: Extensive changes to compress and merge debugging
885 information, and to write some of out directly rather than saving
886 it in memory. Several new functions and structures, and new
887 arguments to existing functions.
888 * ecoff.c (ecoff_compute_reloc_file_positions): Compute
890 (ecoff_get_extr): Use ifdmap instead of ifdbase.

965 * configure.in (nlm32_alpha_vec): Set target64 to true.
967 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are

970 in the backend accessor macros; that should no longer be possible.
