Each symbol is listed along with some simple information about its provenance. If no file name is specified, or \fI\-\fR is used as a file name, \fBllvm-nm\fR will process a bitcode file on its standard input stream. .PP \&\fBllvm-nm\fR's default output format is the traditional \s-1BSD\s0 \fBnm\fR 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. .PP Type code characters currently supported, and their meanings, are as follows: .IP "U" 4 .IX Item "U" Named object is referenced but undefined in this bitcode file .IP "C" 4 .IX Item "C" Common (multiple definitions link together into one def) .IP "W" 4 .IX Item "W" Weak reference (multiple definitions link together into zero or one definitions) .IP "t" 4 .IX Item "t" Local function (text) object .IP "T" 4 .IX Item "T" Global function (text) object .IP "d" 4 .IX Item "d" Local data object .IP "D" 4 .IX Item "D" Global data object .IP "?" 4 Something unrecognizable .PP Because \s-1LLVM\s0 bitcode files typically contain objects that are not considered to have addresses until they are linked into an executable image or dynamically compiled \*(L"just-in-time\*(R", \fBllvm-nm\fR does not print an address for any symbol, even symbols which are defined in the bitcode file. .SH "OPTIONS" .IX Header "OPTIONS" .IP "\fB\-P\fR" 4 .IX Item "-P" Use \s-1POSIX\s0.2 output format. Alias for \fB\-\-format=posix\fR. .IP "\fB\-B\fR (default)" 4 .IX Item "-B (default)" Use \s-1BSD\s0 output format. Alias for \fB\-\-format=bsd\fR. .IP "\fB\-help\fR" 4 .IX Item "-help" Print a summary of command-line options and their meanings. .IP "\fB\-\-defined\-only\fR" 4 .IX Item "--defined-only" Print only symbols defined in this bitcode file (as opposed to symbols which may be referenced by objects in this file, but not defined in this file.) .IP "\fB\-\-extern\-only\fR, \fB\-g\fR" 4 .IX Item "--extern-only, -g" Print only symbols whose definitions are external; that is, accessible from other bitcode files. .IP "\fB\-\-undefined\-only\fR, \fB\-u\fR" 4 .IX Item "--undefined-only, -u" Print only symbols referenced but not defined in this bitcode file. .IP "\fB\-\-format=\fR\fIfmt\fR, \fB\-f\fR" 4 .IX Item "--format=fmt, -f" Select an output format; \fIfmt\fR may be \fIsysv\fR, \fIposix\fR, or \fIbsd\fR. The default is \fIbsd\fR. .SH "BUGS" .IX Header "BUGS" \&\fBllvm-nm\fR cannot demangle \*(C+ mangled names, like \s-1GNU\s0 \fBnm\fR can. .SH "EXIT STATUS" .IX Header "EXIT STATUS" \&\fBllvm-nm\fR exits with an exit code of zero. .SH "SEE ALSO" .IX Header "SEE ALSO" llvm-dis, \fIar\fR\|(1), \fInm\fR\|(1) .SH "AUTHOR" .IX Header "AUTHOR" Maintained by the \s-1LLVM\s0 Team ().
