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

          $ llvm-symbolizer < addr.txt
          main

          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

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.
