v -numeric-sort Sort symbols numerically by their addresses, rather than alphabetically by their names. If line number information can be found, print it For an undefined symbol, look for the line number of a relocation entry which refers to the symbol. For a defined symbol, look for the line number of the address of the l -line-numbers For each symbol, use debugging information to try to find a filename and line number. This option is only available if the toolchain has been built with plugin support plugin name Load the plugin called name to add support for extra target types. g -extern-only Display only external symbols. Only the firstĬharacter of format is significant it can be either upper or lower case. f format -format= format Use the output format format, which can be 'bsd', 'sysv', or 'posix'. This is only meaningful for dynamic objects, such as certain types of shared libraries. D -dynamic Display the dynamic symbols rather than the normal symbols. no-demangle Do not demangle low-level symbol names. The optional demangling style argument can be used to choose anĪppropriate demangling style for your compiler. Different compilers have different mangling styles. Besides removing any initial underscore prepended by the system, this makes C C -demangle Decode ( demangle) low-level symbol names into user-level names. The same as -format=bsd (for compatibility with the MIPS nm). a -debug-syms Display all symbols, even debugger-only symbols normally these are not listed.

o -print-file-name Precede each symbol by the name of the input file (or archive member) in which it was found, rather than identifying the input file once only, before all of

The long and short forms of options, shown here as alternatives, are equivalent. The symbol type is unknown, or object file format specific. Stabs symbols are used to hold debugging information. In this case, the next values printed are the stabs other field, the stabs desc field, and the stab The symbol is a stabs symbol in an a.out object file. On some systems, uppercase indicates that a default value has been specified. When a weak undefined symbol is linked and the symbol is not defined, the value of the symbol isĭetermined in a system-specific manner without error. Symbol, the normal defined symbol is used with no error. When a weak defined symbol is linked with a normal defined The symbol is a weak symbol that has not been specifically tagged as a weak object symbol. On some systems, uppercase indicates that a Undefined symbol is linked and the symbol is not defined, the value of the weak symbol becomes zero with no error.

When a weak defined symbol is linked with a normal defined symbol, the normal defined symbol is used with no error. The dynamic linker will make sure that in the entire process there is just one symbol with this name and type in use. This is a GNU extension to the standard set of ELF symbol bindings. The symbol is in the text (code) section. The symbol is in an uninitialized data section for small objects. The symbol is in a read only data section. The symbols is in a stack unwind section. Then return the value to be used in the relocation. Indicates a symbol which if referenced by a relocation does not evaluate to its address, but instead must be invoked at runtime. This is a GNU extension to the standard set of ELF symbol types. For ELF formatįiles this indicates that the symbol is an indirect function.

Global int variable as opposed to a large global array.įor PE format files this indicates that the symbol is in a section specific to the implementation of DLLs. Some object file formats permit more efficient access to small data objects, such as a The symbol is in an initialized data section for small objects. The symbol is in the initialized data section. If the symbol is definedĪnywhere, the common symbols are treated as undefined references. When linking, multiple common symbols may appear with the same name. The symbol is in the uninitialized data section (known as BSS ). The symbol's value is absolute, and will not be changed by further linking. Uppercase, the symbol is global (external). At least the following types are used others are, as well, depending on the object file format. The symbol value, in the radix selected by options (see below), or hexadecimal by default.

If no object files are listed as arguments, nm assumes the file GNU nm lists the symbols from object files objfile.
