For now, only the sub-command name is completed. No support yet for
completing options to that command. But even this is a huge step as
currently, nothing is completed, and the basic "help sim" is fairly
obtuse as to what exactly the "sim" command accepts.

(xcoff_link_hash_table): Add an "rtld" field.
bfd/
* coff-rs6000.c (xcoff_ppc_relocate_section): Report relocations
against undefined symbols if the symbol's XCOFF_WAS_UNDEFINED
flag is set. Assert that all undefined symbols are either
imported or defined by a dynamic object.
* coff64-rs6000.c (xcoff64_ppc_relocate_section): Likewise.
* xcofflink.c (xcoff_link_add_symbols): Extend function-symbol
handling to all relocations. Only set XCOFF_CALLED for function
symbols.
(xcoff_find_function): New function, split out from...
(bfd_xcoff_export_symbol) ...here.
(xcoff_set_import_path): New function, split out from...
(bfd_xcoff_import_symbol): ...here. Remove assertion for old
meaning of XCOFF_CALLED.
(xcoff_mark_symbol): If we mark an undefined and unimported
symbol, find some way of defining it. If the symbol is a function
descriptor, fill in its definition automatically. If the symbol
is a function, mark its descriptor and allocate room for global
linkage code. Otherwise mark the symbol as implicitly imported.
Move the code for creating function descriptors from...
(xcoff_build_ldsyms): ...here. Use XCOFF_WAS_UNDEFINED to
check for symbols that were implicitly defined.
(xcoff_mark): Don't count any dynamic relocations against
function symbols.
(bfd_xcoff_size_dynamic_sections): Save the rtld parameter
in the xcoff link info.
(xcoff_link_input_bfd): Remove handling of undefined and
unexported symbols.
ld/
* emultempl/aix.em (gld${EMULATION_NAME}_handle_option): Make
-berok and -bernotok control link_info.unresolved_syms_in_objects
and link_info.unresolved_syms_in_shared_libs instead of
force_make_executable.
ld/testsuite/
* ld-powerpc/aix-glink-1.ex, ld-powerpc/aix-glink-1.s,
ld-powerpc/aix-glink-1-32.dd, ld-powerpc/aix-glink-1-64.dd,
ld-powerpc/aix-glink-1-32.d, ld-powerpc/aix-glink-1-64.d: New tests.
* ld-powerpc/aix52.exp: Run them.
2009-03-12 Dave Korn <dave.korn.cygwin@gmail.com>
* coff/internal.h (struct internal_extra_pe_aouthdr): Correct type
of DllCharacteristics flags field to unsigned.
* coff/pe.h (IMAGE_DLL_CHARACTERISTICS_DYNAMIC_BASE,
IMAGE_DLL_CHARACTERISTICS_DYNAMIC_BASE,
IMAGE_DLL_CHARACTERISTICS_NX_COMPAT,
IMAGE_DLLCHARACTERISTICS_NO_ISOLATION,
IMAGE_DLLCHARACTERISTICS_NO_SEH,
IMAGE_DLLCHARACTERISTICS_NO_BIND,
IMAGE_DLLCHARACTERISTICS_WDM_DRIVER,
IMAGE_DLLCHARACTERISTICS_TERMINAL_SERVER_AWARE): New macros to
define flag bit values for DllCharacteristics field of PEAOUTHDR,
PEPAOUTHDR.

(ppc_elf_tls_optimize): Allow out-of-order __tls_get_addr relocs
if section has no old-style calls.
(ppc_elf_relocate_section): Set tls_mask for non-tls relocs too.
Don't try to optimize new-style __tls_get_addr call when handling
arg setup relocs. Instead do so for R_PPC_TLSGD and R_PPC_TLSLD
relocs.
