new local variable special_sections, and pass it to
size_dynamic_sections. Look through the results, and move the
sections around in the mapping so that they are defined correctly.
(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.

* 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.

writable--it's required on Solaris. Cast fprintf argument to

* bfd-in.h (bfd_get_file_window): Update declaration.

Change all uses.
(xcoff_swap_ldhdr_in): New static function.
(xcoff_swap_ldsym_in): New static function.
(xcoff_link_add_symbols): If we just created a descriptor, pass it
to _bfd_generic_link_add_one_symbol, to save a hash lookup.
(xcoff_link_add_dynamic_symbols): Rewrite to read .loader symbols
rather than normal symbol table.
(xcoff_mark): When considering called symbols, check whether the
descriptor is from a dynamic object, rather than the symbol
itself.
(xcoff_build_ldsyms): Likewise.
Cast realloc and malloc return values. If malloc or realloc fail,
set bfd_error_no_memory.
* bfd-in.h (bfd_get_file_window): Change type to boolean.
* bfd-in2.h: Rebuild.
NOTE: Only the BigEndian build has the simulator included, because a
LittleEndian simulator is not constructed at the moment (it should
work, but has not been tested fully).
the run-time support code (interp.c) to provide better tracing, and
also to add profiling and architecture specific support. At the moment
the simulator has a fixed size, fixed address memory area, and
simulates a subset of the IDT monitor calls (enough to execute test
programs).
The other major feature (could even be a bug) is that the simulator
makes use of the GCC "long long" extension. Work has been started to
make this a build configuration option... but there is still a lot of
this to be done.

* (mips_load): Remove unnecessary `db tty0' command. It's all
handled by mips_initialize now.

The mips_initialize() code seemed to have a "funny" switch
statement. I also removed an unnecessary switch into debug monitor
mode just before the call to mips_initialize() in mips_load().
