.SH SYNOPSIS
.nf
\fBdsymutil\fP [\fIoptions\fP] \fIexecutable\fP
.fi
.sp
.SH DESCRIPTION
.sp
\fBdsymutil\fP links the DWARF debug information found in the object files
for an executable \fIexecutable\fP by using debug symbols information contained in
its symbol table. By default, the linked debug information is placed in a
\fB\&.dSYM\fP bundle with the same name as the executable.
.SH OPTIONS
.INDENT 0.0
.TP
.B \-\-arch=<arch>
Link DWARF debug information only for specified CPU architecture types.
Architectures may be specified by name. When using this option, an error will
be returned if any architectures can not be properly linked.  This option can
be specified multiple times, once for each desired architecture. All CPU
architectures will be linked by default and any architectures that can’t be
properly linked will cause \fBdsymutil\fP to return an error.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-dump\-debug\-map
Dump the \fIexecutable\fP’s debug\-map (the list of the object files containing the
debug information) in YAML format and exit. Not DWARF link will take place.
.UNINDENT
.INDENT 0.0
.TP
.B \-f, \-\-flat
Produce a flat dSYM file. A \fB\&.dwarf\fP extension will be appended to the
executable name unless the output file is specified using the \-o option.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-no\-odr
Do not use ODR (One Definition Rule) for uniquing C++ types.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-no\-output
Do the link in memory, but do not emit the result file.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-no\-swiftmodule\-timestamp
Don’t check the timestamp for swiftmodule files.
.UNINDENT
.INDENT 0.0
.TP
.B \-j <n>, \-\-num\-threads=<n>
Specifies the maximum number (\fBn\fP) of simultaneous threads to use when
linking multiple architectures.
.UNINDENT
.INDENT 0.0
.TP
.B \-o <filename>
Specifies an alternate \fBpath\fP to place the dSYM bundle. The default dSYM
bundle path is created by appending \fB\&.dSYM\fP to the executable name.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-oso\-prepend\-path=<path>
Specifies a \fBpath\fP to prepend to all debug symbol object file paths.
.UNINDENT
.INDENT 0.0
.TP
.B \-s, \-\-symtab
Dumps the symbol table found in \fIexecutable\fP or object file(s) and exits.
.UNINDENT
.INDENT 0.0
.TP
.B \-v, \-\-verbose
Display verbose information when linking.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-version
Display the version of the tool.
.UNINDENT
.INDENT 0.0
.TP
.B \-y
Treat \fIexecutable\fP as a YAML debug\-map rather than an executable.
.UNINDENT
.SH EXIT STATUS
.sp
\fBdsymutil\fP returns 0 if the DWARF debug information was linked
successfully. Otherwise, it returns 1.
