.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.
