.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.
