NAME

6       llvm-symbolizer - convert addresses into source code locations
7

SYNOPSIS

9       llvm-symbolizer [options]
10

DESCRIPTION

12       llvm-symbolizer  reads  object  file  names and addresses from standard
13       input and prints corresponding source code locations to  standard  out‐
14       put.  If object file is specified in command line, llvm-symbolizer pro‐
15       cesses only addresses from standard input, the rest is output verbatim.
16       This  program  uses  debug info sections and symbol table in the object
17       files.

OPTIONS

66       -obj   Path to object file to be symbolized.
67
68       -functions=[none|short|linkage]
69              Specify the way function names are printed (omit function  name,
70              print  short  function name, or print full linkage name, respec‐
71              tively).  Defaults to linkage.
72
73       -use-symbol-table
74              Prefer function names stored in symbol table to  function  names
75              in debug info sections. Defaults to true.
76
77       -demangle
78              Print demangled function names. Defaults to true.
79
80       -inlining
81              If  a source code location is in an inlined function, prints all
82              the inlnied frames. Defaults to true.
83
84       -default-arch
85              If a binary contains object  files  for  multiple  architectures
86              (e.g.  it  is  a  Mach-O universal binary), symbolize the object
87              file for a given architecture.  You can also  specify  architec‐
88              ture  by writing binary_name:arch_name in the input (see example
89              above). If architecture is not specified in either way,  address
90              will not be symbolized. Defaults to empty string.
91
92       -dsym-hint=<path/to/file.dSYM>
93              (Darwin-only flag). If the debug info for a binary isn't present
94              in the default location, look for the debug info  at  the  .dSYM
95              path  provided  via  the  -dsym-hint flag. This flag can be used
96              multiple times.
97
98       -print-address
99              Print address before  the  source  code  location.  Defaults  to
100              false.
101
102       -pretty-print
103              Print  human readable output. If -inlining is specified, enclos‐
104              ing scope is prefixed by (inlined by). Refer to listed examples.
105

EXIT STATUS

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