llvm-nm - list LLVM bitcode and object file's symbol table
:program:`llvm-nm` [options] [filenames...]
The :program:`llvm-nm` utility lists the names of symbols from the LLVM bitcode files, object files, or :program:`ar` archives containing them, named on the command line. Each symbol is listed along with some simple information about its provenance. If no file name is specified, or - is used as a file name, :program:`llvm-nm` will process a file on its standard input stream.
:program:`llvm-nm`'s default output format is the traditional BSD :program:`nm` output format. Each such output record consists of an (optional) 8-digit hexadecimal address, followed by a type code character, followed by a name, for each symbol. One record is printed per line; fields are separated by spaces. When the address is omitted, it is replaced by 8 spaces.
Type code characters currently supported, and their meanings, are as follows:
Named object is referenced but undefined in this bitcode file
Common (multiple definitions link together into one def)
Weak reference (multiple definitions link together into zero or one definitions)
Local function (text) object
Global function (text) object
Local data object
Global data object
Because LLVM bitcode files typically contain objects that are not considered to have addresses until they are linked into an executable image or dynamically compiled "just-in-time", :program:`llvm-nm` does not print an address for any symbol in an LLVM bitcode file, even symbols which are defined in the bitcode file.
:program:`llvm-nm` exits with an exit code of zero.
