include/coff/

	* internal.h (C_AIX_WEAKEXT): New macro.
	(C_WEAKEXT): Use the GNU definition in the generic part of the file,
	and conditionally reset it to C_AIX_WEAKEXT in the XCOFF part of
	the file.
	(CSECT_SYM_P): New macro.
	* xcoff.h (L_WEAK): Define.
	(EXTERN_SYM_P): New macro.

bfd/
	* coffcode.h (coff_pointerize_aux_hook): Update CSECT_SYM_P to
	check whether a symbol has csect information.
	(coff_print_aux): Likewise.
	* coff-rs6000.c (_bfd_xcoff_swap_aux_in): Handle auxillary csect
	information for C_AIX_WEAKEXT too.
	(_bfd_xcoff_swap_aux_out): Likewise.
	(xcoff_reloc_type_br): Handle defweak symbols too.
	* coff64-rs6000.c (_bfd_xcoff64_swap_aux_in): Handle auxillary csect
	information for C_AIX_WEAKEXT too.
	(_bfd_xcoff64_swap_aux_out): Likewise.
	(xcoff64_reloc_type_br): Handle defweak symbols too.
	* coffgen.c (coff_print_symbol): Handle auxillary function
	information for C_AIX_WEAKEXT too.
	* xcofflink.c (_bfd_xcoff_canonicalize_dynamic_symtab): Set BSF_WEAK
	instead of BSF_GLOBAL if the L_WEAK flag is set.
	(xcoff_dynamic_definition_p): New function.
	(xcoff_link_add_dynamic_symbols): Use it to decide whether ldsym
	defines h.  Don't change h if ldsym isn't the definition.  Otherwise,
	always take the symbol class from the ldsym.  Use weak bfd symbol
	types for weak ldsyms.
	(xcoff_link_add_symbols): Use CSECT_SYM_P and EXTERN_SYM_P.
	Fix the check for whether a definition is from a shared object.
	Allow redefinitions of weak symbols.
	(xcoff_link_check_ar_symbols): Use EXTERN_SYM_P.
	(xcoff_keep_symbol_p): Likewise.
	(bfd_xcoff_size_dynamic_sections): Use CSECT_SYM_P.
	(xcoff_link_input_bfd): Use CSECT_SYM_P and EXTERN_SYM_P.
	Add .loader entries for C_AIX_WEAKEXT as well as C_EXT symbols,
	but mark them as L_WEAK.
	(xcoff_write_global_symbol): Treat weak symbols as C_AIX_WEAKEXT
	instead of C_EXT if C_AIX_WEAKEXT == C_WEAKEXT.

gas/
	* config/tc-ppc.c (ppc_frob_symbol): Add csect information for
	C_AIX_WEAKEXT too.
