+
+ * 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.
