NAME

llvm-symbolizer - convert addresses into source code locations

SYNOPSIS

llvm-symbolizer [options]

DESCRIPTION

llvm-symbolizer reads object file names and addresses from standard input and prints corresponding source code locations to standard output. If object file is specified in command line, llvm-symbolizer reads only addresses from standard input. This program uses debug info sections and symbol table in the object files.

EXAMPLE

$ cat addr.txt
a.out 0x4004f4
/tmp/b.out 0x400528
/tmp/c.so 0x710
/tmp/mach_universal_binary:i386 0x1f84
/tmp/mach_universal_binary:x86_64 0x100000f24
$ llvm-symbolizer < addr.txt
main
/tmp/a.cc:4
f(int, int)
/tmp/b.cc:11
h_inlined_into_g
/tmp/header.h:2

$ cat addr2.txt
0x4004f4
0x401000
$ llvm-symbolizer -obj=a.out < addr2.txt
main
/tmp/a.cc:4
foo(int)
/tmp/a.cc:12


OPTIONS

Path to object file to be symbolized.

Specify the way function names are printed (omit function name, print short function name, or print full linkage name, respectively). Defaults to linkage.

Prefer function names stored in symbol table to function names in debug info sections. Defaults to true.

Print demangled function names. Defaults to true.

If a source code location is in an inlined function, prints all the inlnied frames. Defaults to true.

If a binary contains object files for multiple architectures (e.g. it is a Mach-O universal binary), symbolize the object file for a given architecture. You can also specify architecture by writing binary_name:arch_name in the input (see example above). If architecture is not specified in either way, address will not be symbolized. Defaults to empty string.

(Darwin-only flag). If the debug info for a binary isn't present in the default location, look for the debug info at the .dSYM path provided via the -dsym-hint flag. This flag can be used multiple times.

EXIT STATUS

llvm-symbolizer returns 0. Other exit codes imply internal program error.
