llvm-symbolizer - convert addresses into source code locations — LLVM 3.4 documentation

# 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. 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
    g_inlined_into_f
    /tmp/header.h:7
    f_inlined_into_main
    /tmp/source.cc:3
    main
    /tmp/source.cc:8

    _main
    /tmp/source_i386.cc:8

    _main
    /tmp/source_x86_64.cc:8

## OPTIONS

`-functions```

  Print function names as well as source file/line locations. Defaults to true.

`-use-symbol-table```

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

`-demangle```

  Print demangled function names. Defaults to true.

`-inlining```

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

`-default-arch```

  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.

## EXIT STATUS

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