.SH SYNOPSIS
.sp
\fBllvm\-symbolizer\fP [options]
.SH DESCRIPTION
.sp
\fBllvm\-symbolizer\fP 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, \fBllvm\-symbolizer\fP
processes only addresses from standard input, the rest is output verbatim.
This program uses debug info sections and symbol table in the object files.

.SH OPTIONS
.INDENT 0.0
.TP
.B \-obj
Path to object file to be symbolized.
.UNINDENT
.INDENT 0.0
.TP
.B \-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 \fBlinkage\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B \-use\-symbol\-table
Prefer function names stored in symbol table to function names
in debug info sections. Defaults to true.
.UNINDENT
.INDENT 0.0
.TP
.B \-demangle
Print demangled function names. Defaults to true.
.UNINDENT
.INDENT 0.0
.TP
.B \-inlining
If a source code location is in an inlined function, prints all the
inlnied frames. Defaults to true.
.UNINDENT
.INDENT 0.0
.TP
.B \-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 \fBbinary_name:arch_name\fP in the
input (see example above). If architecture is not specified in either way,
address will not be symbolized. Defaults to empty string.
.UNINDENT
.INDENT 0.0
.TP
.B \-dsym\-hint=<path/to/file.dSYM>
(Darwin\-only flag). If the debug info for a binary isn\(aqt present in the default
location, look for the debug info at the .dSYM path provided via the
\fB\-dsym\-hint\fP flag. This flag can be used multiple times.
.UNINDENT
.INDENT 0.0
.TP
.B \-print\-address
Print address before the source code location. Defaults to false.
.UNINDENT
.INDENT 0.0
.TP
.B \-pretty\-print
Print human readable output. If \fB\-inlining\fP is specified, enclosing scope is
prefixed by (inlined by). Refer to listed examples.
.UNINDENT
.SH EXIT STATUS
.sp
\fBllvm\-symbolizer\fP returns 0. Other exit codes imply internal program error.
