LLVM: llvm-nm tool


NAME

llvm-nm

SYNOPSIS

llvm-nm [options] [filenames...]

DESCRIPTION

The llvm-nm utility lists the names of symbols from the LLVM bytecode files named on the command line, along with some ancillary information about each symbol. If no filename is specified, or - is used as a filename, llvm-nm reads its input from standard input.

llvm-nm's default output format is the traditional BSD nm(1) 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:

UNamed object is referenced but undefined in this bytecode file
CCommon (multiple defs link together into one def)
WWeak reference (multiple defs link together into zero or one defs)
tLocal function (text) object
TGlobal function (text) object
dLocal data object
DGlobal data object
?Something unrecognizable

Because LLVM bytecode 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", llvm-nm does not print an address for any symbol, even symbols which are defined in the bytecode file.

OPTIONS

BUGS

llvm-nm cannot currently see inside ar(1) library archive files, like nm(1) can. It cannot demangle C++ mangled names, like GNU nm(1) can.

EXIT STATUS

llvm-nm exits with an exit code of zero.
