+.TH DWARFDUMP
+.SH NAME
+dwarfdump \- dumps DWARF debug information of an ELF object
+.SH SYNOPSIS
+.B dwarfdump
+[-abcdefilmoprsvy] [-t{afv}] [-u\f2objectfile\fP] \f2filename\fP
+.SH DESCRIPTION
+The 
+.B dwarfdump
+command prints DWARF sections as requested by specific options.
+With no options nothing prints!
+.PP
+The format is intended to be human readable.
+If a script is to parse the output, the
+.B \-d
+option is useful.
+.P
+Not all sections actually exist in any given object file.
+.P
+The format may change from release to release, so it is
+unwise to depend too heavily on the format.
+.P
+.PP
+Frame information (.debug_frame and .eh_frame) is heavily
+dependent on the ABI/ISA of the object file.  
+The '-R' option uses a built-in 'generic' register name set
+handling up to 1000 registers named r0-r999.
+The '-x abi=<abi>'
+flavors below describe how to name an abi and use that to guide
+the -f or -F processing.
+Without '-R' or '-x abi=<abi>'/ dwarfdump ignores
+the dwarfdump.conf file and uses compiled-in MIPS/IRIX 
+conventions).  
+If no '-x name=<path>' is given, dwarfdump
+looks for "./dwarfdump.conf", "$HOME/.dwarfdump.conf", "<install-prefix>/lib/dwarfdump.conf" and takes the first it finds.
+If one or more '-x name=<path>' is given the last of these is
+used and all other such files ignored.
+.PP
+The 
+.B dwarfdump
+command accepts one or more of the following options:
+.RS
+.TP
+.B \-a
+Dumps all sections.
+Same as 
+.B \-bcfilmoprsy
+.BR \-tfv .
+.TP
+.B \-b
+Dumps the .debug_abbrev section.  
+.TP
+.B \-c
+Dumps the .debug_loc section.
+.TP
+.B \-d
+Dense mode.  Each die information of the .debug_info section is 
+printed in one-line format.  This option does not imply \fB\-i\fP.  
+.TP
+.B \-e
+Ellipsis mode.  Short names for DW_TAG_* and DW_ATTR_* are used 
+in the output for the .debug_info section.  
+.TP
+.B \-f
+Dumps the .debug_frame section.
+.TP
+.B \-i
+Dumps the .debug_info section.
+.TP
+.B \-l
+Dumps the .debug_line information.  
+.TP
+.B \-m
+Dumps the .debug_macinfo section.
+.TP
+.B \-o
+Dumps the .reloc_debug_* sections.
+.TP
+.B \-p
+Dumps the .debug_pubnames section.
+.TP
+.B \-r
+Dumps the .debug_aranges section.
+.TP
+.B \-s
+Dumps .debug_string section.
+.TP
+.B \-ta
+Same as 
+.B \-tfv.
+.TP
+.B \-tf
+Dumps the .debug_static_funcs section.
+.TP
+.B \-tv
+Dumps the .debug_static_vars section.
+.TP
+.BI \-u ofile
+Restricts the dumping of sections to the named
+compilation unit.
+.TP
+.B \-v
+Verbose mode.  Shows more detailed information.  
+More detailed information about the .debug_frame section prints if
+2 or 3 
+.B \-v
+options are given.
+.TP
+.B \-w
+Dumps the .debug_weaknames section.
+.TP
+.B \-x abi=<conf>
+where abi=names an abi in dwarfdump.conf (see the
+abiname: command in dwarfdump.conf).
+.TP
+.B \-x name=<conf>
+where name=names the full pathname of a dwarfdump configuration
+file.  Default install location is /usr/local/lib/dwarfdump.conf.
+dwarfdump looks first for local ./dwarfdump.conf, then
+for $HOME/.dwarfdump.conf then  for  /usr/local/lib/dwarfdump.conf.
+The predefined abi names in dwarfdump.conf are
+generic, ia64,  m68k, x86, and x86_64.
+.TP
+.B \-y
+Dumps the .debug_types section.
+.SH FILES
+dwarfdump
+./dwarfdump.conf
+$(HOME)/.dwarfdump.conf
+<install-prefix>/lib/dwarfdump.conf
+.SH NOTES
+In some cases compilers use DW_FORM_data1 (for example)
+and in such cases the signedness of the value must be taken
+from context. Rather than attempt to determine the
+context, dwarfdump prints the value with both signednesses
+whenever there is ambiguity about the correct interpretation.
+For example, 
+"DW_AT_const_value           176(as signed = -80)".
+For normal DWARF consumers that correctly and fully
+evaluate all attributes there is no ambiguity of signedness:
+the ambiguity for dwarfdump is due to dwarfdump evaluating
+DIEs in a simple order and not keeping track of much context.
+.SH BUGS
+Support for DWARF3 is being completed but may not be complete.
