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
       processes  only addresses from standard input, the rest is output verbatim.  This program uses debug info
       sections and symbol table in the object files.

EXAMPLE

          $ cat addr.txt
          a.out 0x4004f4
          /tmp/b.out 0x400528

          $ llvm-symbolizer < addr.txt
          main

          $cat addr.txt
          0x40054d
          $llvm-symbolizer -inlining -print-address -pretty-print -obj=addr.exe < addr.txt

OPTIONS

       -obj, -exe, -e
              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, -C
              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, -addresses, -a
              Print address before the source code location. Defaults to false.

       -pretty-print, -p
              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.
