+
+ Added -D (--dynamic) option to nm and -T (--dynamic-syms) and -R
+ (--dynamic-reloc) arguments to objdump.
+ * nm.c (dynamic): New static variable.
+ (long_options): Added "dynamic".
+ (usage): Mention -D and --dynamic.
+ (main): Add D to getopt string. Handle -D by setting dynamic.
+ (display_rel_file): If dynamic is non-zero, read dynamic symbols
+ rather than normal symbols.
+ * nm.1: Updated for -D (--dynamic) option.
+ * objdump.c (dump_dynamic_symtab): New global variable.
+ (dump_dynamic_reloc_info): New global variable.
+ (dynsyms, dynsymcount): New global variables.
+ (usage): Mention -R, -T, --dynamic-syms and --dynamic-reloc.
+ (long_options): Added "dynamic-reloc" and "dynamic-syms".
+ (slurp_symtab): If no symbols, return rather than exit.
+ (slurp_dynamic_symtab): New function.
+ (display_bfd): Handle dump_dynamic_symtab and
+ dump_dynamic_reloc_info.
+ (dump_symbols): Take new dynamic argument, indicating whether to
+ display dynamic symbols.
+ (dump_relocs): Move most printing into dump_reloc_set.
+ (dump_dynamic_relocs): New function.
+ (dump_reloc_set): New function, extracted from dump_relocs.
+ (main): Add R and T to getopt string. Handle -T by setting
+ dump_dynamic_symtab and -R by setting dump_dynamic_reloc_info.
+ * objdump.1: Updated for -R (--dynamic-reloc) and -T
+ (--dynamic-syms) options.
+ * binutils.texi: Updated for new nm and objdump options.
