* nm.c (struct extended_symbol_info): New strcuture: Add the size
|
||||
of the symbols to the information provided by the symbol_info
|
||||
structure.
|
||||
(print_symbols): Pass the symbol size to print_symbol.
|
||||
(print_size_symbols): Pass the symbol size to print_symbol.
|
||||
(print_symbol): Extra argument: The size of the symbol. Store
|
||||
this in the extended_symbol_info structure.
|
||||
(print_symbol_info): Change type of info parameter to
|
||||
extended_symbol_info. Display the size, if known.
|
||||
(print_symbol_info_posix): Likewise.
|
||||
(print_symbol_info_sysv): Likewise.
