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
       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

          f_inlined_into_main
          /tmp/source.cc:3
          main

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

          foo(int)
          /tmp/a.cc:12
          $cat addr.txt
          0x40054d
          $llvm-symbolizer -inlining -print-address -pretty-print -obj=addr.exe < addr.txt
          0x40054d: inc at /tmp/x.c:3:3
           (inlined by) main at /tmp/x.c:9:0
          $llvm-symbolizer -inlining -pretty-print -obj=addr.exe < addr.txt
          inc at /tmp/x.c:3:3
           (inlined by) main at /tmp/x.c:9:0

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,
              respectively).  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
              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.

       -dsym-hint=<path/to/file.dSYM>
              (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.

       -print-address
              Print address before the source code location. Defaults to
              false.

       -pretty-print
              Print human readable output. If -inlining is specified,
              enclosing scope is prefixed by (inlined by). Refer to listed
              examples.

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