llvm-symbolizer - convert addresses into source code locations
|
|
==============================================================
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
:program:`llvm-symbolizer` [options]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
:program:`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, :program:`llvm-symbolizer` reads
|
|
only addresses from standard input. This
|
|
program uses debug info sections and symbol table in the object files.
|
|
|

OPTIONS
|
|
-------
|
|
|
|
.. option:: -obj
|
|
Path to object file to be symbolized.
|
|
|
|
.. option:: -functions
|
|
|
|
Print function names as well as source file/line locations. Defaults to true.
|
|
|
|
.. option:: -use-symbol-table
|
|
|
|
Prefer function names stored in symbol table to function names
|
|
in debug info sections. Defaults to true.
|
|
|
|
.. option:: -demangle
|
|
|
|
Print demangled function names. Defaults to true.
|
|
|
|
.. option:: -inlining
|
|
|
|
If a source code location is in an inlined function, prints all the
|
|
inlnied frames. Defaults to true.
|
|
|
|
.. option:: -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.
|
|
|
|
EXIT STATUS
|
|
-----------
|
|
|
|
:program:`llvm-symbolizer` returns 0. Other exit codes imply internal program error.
