+.SH NAME
+llvm-dwarfutil \- A tool to copy and manipulate debug info
+.SH SYNOPSIS
+.sp
+\fBllvm\-dwarfutil\fP [\fIoptions\fP] \fIinput\fP \fIoutput\fP
+.SH DESCRIPTION
+.sp
+\fBllvm\-dwarfutil\fP is a tool to copy and manipulate debug info.
+.sp
+In basic usage, it makes a semantic copy of the input to the output. If any
+options are specified, the output may be modified along the way, e.g.
+by removing unused debug info.
+.sp
+If "\-" is specified for the input file, the input is read from the program\(aqs
+standard input stream. If "\-" is specified for the output file, the output
+is written to the standard output stream of the program.
+.sp
+The tool is still in active development.
+.SH COMMAND-LINE OPTIONS
+.INDENT 0.0
+.TP
+.B \-\-garbage\-collection
+Removes pieces of debug information related to discarded sections.
+When the linker does section garbage collection the abandoned debug info
+is left behind. Such abandoned debug info references address ranges using
+tombstone values. Thus, when this option is specified, the tool removes
+debug info which is marked with the tombstone value.
+.sp
+That option is enabled by default.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-\-odr\-deduplication
+Remove duplicated types (if "One Definition Rule" is supported by source
+language). Keeps first type definition and removes other definitions,
+potentially significantly reducing the size of output debug info.
+.sp
+That option is enabled by default.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-\-help, \-h
+Print a summary of command line options.
+.UNINDENT

+.B \-\-no\-garbage\-collection

+.UNINDENT
+.INDENT 0.0

+.TP
+.B \-\-no\-separate\-debug\-file
+Disable \fI\%\-\-separate\-debug\-file\fP\&.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-\-num\-threads=<n>, \-j
+Specifies the maximum number (\fIn\fP) of simultaneous threads to use
+for processing.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-\-separate\-debug\-file
+Generate separate file containing output debug info. Using
+\fBllvm\-dwarfutil\fP with that option equals to the
+following set of commands:

+.TP
+.B \-\-tombstone=<value>
+<value> can be one of the following values:
+.INDENT 7.0
+.INDENT 3.5
+.INDENT 0.0
+.IP \(bu 2
+\fIbfd\fP: zero for all addresses and [1,1] for DWARF v4 (or less) address ranges and exec.
+.IP \(bu 2
+\fImaxpc\fP: \-1 for all addresses and \-2 for DWARF v4 (or less) address ranges.
+.IP \(bu 2
+\fIuniversal\fP: both \fIbfd\fP and \fImaxpc\fP\&.
+.IP \(bu 2
+\fIexec\fP: match with address ranges of executable sections.
+.UNINDENT
+.sp
+The value \fIuniversal\fP is used by default.

+.INDENT 0.0

+.B \-\-verbose
+Enable verbose logging. This option disables multi\-thread mode.

+.B \-\-verify
+Run the DWARF verifier on the output DWARF debug info.
+.UNINDENT
