LLVM-SYMBOLIZER(1)                   LLVM                   LLVM-SYMBOLIZER(1)

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  out-
       put.   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
          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
          $ cat addr2.txt
          0x4004f4
          0x401000
          $ llvm-symbolizer -obj=a.out < addr2.txt
          main
          /tmp/a.cc:4

          foo(int)
          /tmp/a.cc:12

OPTIONS
       -obj   Path to object file to be symbolized.

       -functions=[none|short|linkage]
              Specify  the way function names are printed (omit function name,
              print short function name, or print full linkage  name,  respec-
              tively).  Defaults to linkage.

       -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 architec-
              ture 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.
