+The B<llvm-nm> utility lists the names of symbols from the LLVM bitcode files,

 Each symbol is listed along with some simple information about its provenance.

 B<llvm-nm>'s default output format is the traditional BSD B<nm> output format.
 Each such output record consists of an (optional) 8-digit hexadecimal address,
