1 llvm-symbolizer - convert addresses into source code locations
2 ==============================================================
7 :program:`llvm-symbolizer` [options]
12 :program:`llvm-symbolizer` reads object file names and addresses from standard
13 input and prints corresponding source code locations to standard output.
14 If object file is specified in command line, :program:`llvm-symbolizer`
15 processes only addresses from standard input, the rest is output verbatim.
16 This program uses debug info sections and symbol table in the object files.

73 Path to object file to be symbolized.
75 .. option:: -functions=[none|short|linkage]
77 Specify the way function names are printed (omit function name,
78 print short function name, or print full linkage name, respectively).
79 Defaults to ``linkage``.
81 .. option:: -use-symbol-table
83 Prefer function names stored in symbol table to function names
84 in debug info sections. Defaults to true.
88 Print demangled function names. Defaults to true.
92 If a source code location is in an inlined function, prints all the
93 inlnied frames. Defaults to true.
95 .. option:: -default-arch
97 If a binary contains object files for multiple architectures (e.g. it is a
98 Mach-O universal binary), symbolize the object file for a given architecture.
99 You can also specify architecture by writing ``binary_name:arch_name`` in the
100 input (see example above). If architecture is not specified in either way,
101 address will not be symbolized. Defaults to empty string.
103 .. option:: -dsym-hint=<path/to/file.dSYM>
105 (Darwin-only flag). If the debug info for a binary isn't present in the default
106 location, look for the debug info at the .dSYM path provided via the
107 ``-dsym-hint`` flag. This flag can be used multiple times.
109 .. option:: -print-address
111 Print address before the source code location. Defaults to false.
113 .. option:: -pretty-print
115 Print human readable output. If ``-inlining`` is specified, enclosing scope is
116 prefixed by (inlined by). Refer to listed examples.
121 :program:`llvm-symbolizer` returns 0. Other exit codes imply internal program error.
