/* addr2line.c -- convert addresses to line number and function name
Updated soruces in binutils/* to compile cleanly with -Wc++-compat. * binutils/addr2line.c (slurp_symtab): Fix casts. Introduce variable minisyms to avoid aliasing varning. * binutils/ar.c: Add casts. (normalize): Use name del instead of delete. (display_target_list,display_info_table): Change loop counter variable a to int. * binutils/bucomm.c: Add casts. * binutils/debug.c: Update function to use new names. (struct debug_baseclass): Rename member from virtual to is_virtual. (struct debug_type_s,struct debug_field_s,struct debug_baseclass_s,struct debug_method_s,struct debug_method_variant_s,struct debug_type_s): Rename struct from avoid name collision. * /binutils/debug.h: Use new struct names. * binutils/dwarf.c: Add casts. (free_debug_memory): Change loop counter variable a to int. * binutils/ieee.c: Add casts. (enum ieee_var_kind): Move to top level. (ieee_class_baseclass): Rename parameter virtual to is_virtual. (ieee_class_method_var): Rename variable virtual to is_virtual. * binutils/nm.c: Add casts. * binutils/objcopy.c: Add casts. (copy_archive): Rename variable delete to del. * binutils/objdump.c: Add casts. (dump_dwarf_section): Change loop counter variable i to int. * binutils/prdbg.c: Add casts. (pr_class_baseclass,tg_class_baseclass): Rename parameters virtual to is_virtual. * binutils/readelf.c: Add casts. (struct ia64_unw_table_entry,struct hppa_unw_table_entry): Move to top level. * binutils/size.c: Add casts. * binutils/stabs.c (parse_stab_type, parse_stab_range_type) (parse_stab_cpp_abbrev): Rename parameter from typename to type_name. (parse_stab_baseclasses): Rename variable virtual to is_virtual. * binutils/strings.c: Add casts. * binutils/wrstabs.c (stab_class_baseclass): Rename parameter virtual to is_virtual.
