   6 Mon Nov 22 14:17:36 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
   7
   8         * ecoff.c (ecoff_mkobject): Don't create .scommon section; linker
   9         no longer requires it.
  10         (ecoff_bfd_seclet_link, ecoff_sizeof_headers,
  11         ecoff_write_object_contents): Don't treat .scommon section

  18         * bfd/config/delta88.mh (HDEPFILES): Defined to be ptrace-core.o.
  19         * bfd/ptrace-core.c:  New file for dealing with core files with
  20         start with the ptrace_user structure found on BCS compliant systems.
  21         * bfd/targets.c (ptrace_core_vec):  New vector.
  22
  23 Mon Nov 22 02:33:12 1993  Jeffrey A. Law  (law@snake.cs.utah.edu)
  24
  25         * Minimal support for reading SOM fixup streams.  Allows
  26         objdump -r to do something reasonable.
  27         * som.c (som_get_reloc_upper_bound): Implement.
  28         (som_canonicalize_reloc): Implement.
  29         (som_set_reloc_info, som_slurp_reloc_table): New functions.

  31 Fri Nov 19 14:34:04 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  32
  33         * coff-a29k.c (a29k_reloc): For R_IREL, don't left shift
  34         signed_value before sign extending it.  Don't subtract out
  35         reloc_entry->address.  This makes it compatible with what gas is
  36         generating.
  37
  38         * elfcode.h (elf_fake_sections): Accept .sbss as the name for a
  39         SHT_NOBITS sections.

  41         SHT_NOBITS section.
  42         (assign_file_positions_except_relocs): Only force sh_offset and
  43         sh_addr to match modulo maxpagesize for a section which is not
  44         SHT_NOBITS.  Changed the method used to force page alignment after
  45         a SHT_NOBITS section to only do it for the last such consecutive
  46         section, and to really force page alignment.
  47
  48 Fri Nov 19 04:02:01 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)
  49
  50         * coffcode.h (coff_slurp_symbol_table): Print more verbose message
  51         in the case of an unknown (or unhandled) storage class.
  52
  53         * config/i386-lynx.mt (TDEFINES): FPRINTF_ALREADY_DECLARED should
  54         not be defined here, since it is a host attribute, not a target
  55         one.
  56         * config/m68k-lynx.mt, config/sparc-lynx.mt: Ditto.
  57

 105         (assign_file_positions_except_relocs): Don't consider section 0.
 106         In the main loop, skip the symtab and strtab sections, since their
 107         positions are set elsewhere.

 307
 308         * bout.c (b_out_reloc_type_lookup): Return type should point to

 404         BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,

 422         MY_canonicalize_reloc, MY_write_object_contents): Don't define in
 423         terms of MY, because that causes a recusive invocation of CAT when
