+
+ * xcofflink.c (XCOFF_DESCRIPTOR): Define.
+ (struct xcoff_link_hash_table): Add descriptor_section and
+ special_sections fields.
+ (_bfd_xcoff_bfd_link_hash_table_create): Initialize new fields.
+ (xcoff_link_add_symbols): Set linkage section alignment. Create
+ descriptor section. Check for magic symbol names (_text, etc.),
+ and record them in special_sections if found. Set
+ XCOFF_DESCRIPTOR flag for a function descriptor, and set its
+ descriptor field to point back to the function code symbol.
+ (xcoff_sweep): Always mark the special descriptor_section.
+ (bfd_xcoff_export_symbol): Check whether the symbol might be a
+ function descriptor, and mark it if it is.
+ (bfd_xcoff_size_dynamic_sections): Add new special_sections
+ parameter, and fill it in. Allocate space for the descriptor
+ section.
+ (xcoff_build_ldsyms): Set XCOFF_DEF_REGULAR flag when defining
+ global linkage code. If an undefined function descriptor is
+ exported, arrange to define it. Warn about any other undefined
+ exported symbol.
+ (_bfd_xcoff_bfd_final_link): Write out the descriptor section.
+ (xcoff_write_global_symbol): Create a function descriptor when
+ necessary.
+ * bfd-in.h (bfd_xcoff_size_dynamic_sections): Update declaration.
+ * bfd-in2.h: Rebuild.

+
+ * coff-ppc.c (ppc_coff_link_hash_entry): new types for hashing
+ (ppc_coff_link_hash_table): new types for hashing
+ (ppc_coff_link_hash_newfunc): hash entry constructor
+ (ppc_coff_link_hash_table_init): hash table initializer
+ (ppc_coff_link_hash_table_create): hash table constructor
+ (ppc_record_toc_entry): changed references to hash table
+ (coff_ppc_relocate_section): changed references to hash table
+
+ * libcoff-in.h (coff_link_hash_entry): removed toc_offset
+ * libcoff.h: Rebuild
+
+ * cofflink.c (_bfd_coff_link_hash_newfunc): removed toc_offset init
+ (coff_link_add_symbols): removed toc_offset init
+
+Thu Nov 9 04:00:38 1995 Ken Raeburn <raeburn@cygnus.com>
+
+ * Makefile.in (.dep1): Make sure the file mkdep is to write exists
+ first.
+
+ * configure.in: Added new option --with[out]-mmap. Set USE_MMAP
+ if it is given and mmep is available.
+ * acconfig.h: Undef USE_MMAP.
+ * configure, config.in: Regenerated.
+ * aoutx.h: If USE_MMAP is not defined, do all symbol and string
+ table handling the old way.
+ (aout_get_external_symbols): Don't complain if last byte of string
+ table is nonzero.
+ * libbfd.c [HAVE_MADVISE]: Include sys/types.h and sys/mman.h.
+ (bfd_free_window) [! USE_MMAP]: Don't define.
+ (bfd_get_file_window,
+ _bfd_generic_get_section_contents_in_window) [! USE_MMAP]: Abort.

+
+ * coff-a29k.c (SIGN_EXTEND_HWORD): Use ~0xffff rather than
+ 0xffff0000.
+
Wed Nov 8 11:31:11 1995 Ian Lance Taylor <ian@cygnus.com>
+ * coff-a29k.c (a29k_reloc): Change handling of R_IREL reloc to be
+ compatible with AMD generated COFF files. Try to support both AMD
+ and GNU formats simultaneously.
+ (coff_a29k_relocate_section): Likewise.
+
+ * libbfd.c (bfd_get_file_window): Change writable parameter from
+ int to boolean; update all callers. Pass MAP_SHARED if not
+ writable--it's required on Solaris. Cast fprintf argument to
+ avoid warning.
+ * bfd-in.h (bfd_get_file_window): Update declaration.
+ * bfd-in2.h: Rebuild.
+ * aoutx.h: Update calls to bfd_get_file_window.
+
+ * xcofflink.c (XCOFF_DEF_DYNAMIC): Rename from XCOFF_REF_DYNAMIC.
+ Change all uses.
+ (xcoff_swap_ldhdr_in): New static function.
+ (xcoff_swap_ldsym_in): New static function.
+ (xcoff_find_reloc): Handle the case of a single reloc correctly.
+ (xcoff_link_add_symbols): If we just created a descriptor, pass it
+ to _bfd_generic_link_add_one_symbol, to save a hash lookup.
+ Handle XTY_ER/XMC_XO symbols correctly.
+ (xcoff_link_add_dynamic_symbols): Rewrite to read .loader symbols
+ rather than normal symbol table.
+ (bfd_xcoff_import_symbol): It's not an error if the symbol is
+ already defined with the same absolute value.
+ (xcoff_mark): When considering called symbols, check whether the
+ descriptor is from a dynamic object, rather than the symbol
+ itself.
+ (xcoff_build_ldsyms): Likewise.
+
* libbfd.c (bfd_get_file_window): Change return type to boolean.
Cast realloc and malloc return values. If malloc or realloc fail,
set bfd_error_no_memory.
