001
NAME
002
dwarfdump -- dump DWARF debug information.
003
004
SYNOPSIS
005
dwarfdump [options] file1 file2 ...
006
007
DESCRIPTION
008
For each operand that names a mach-o or 32 bit ELF file, dwarfdump
009
disassembles the DWARF data found within the file. Only the .debug_info
010
section is disassembled unless one of the --debug-XXXX or --all options
011
are specified.
012
013
The following options are available:
014
015
-a, --all
016
Dump disassembly of all DWARF sections -- by default only the
017
.debug_info section is disassembled, or individual sections can be
018
specified by using the --debug-XXXX options.
019
020
--arch=ARCH
021
Dump DWARF debug information for the specified CPU architecture.
022
Architectures may be specified by name or by number. This option
023
can be specified multiple times, once for each desired
024
architecture. All architectures will be disassembled by default.
025
026
-c, --show-children
027
Show a DIE's children when using the --debug-info=OFFSET, --find,
028
and --name options.
029
030
--eh-frame[=SECTION]
031
Dump exception handling frame information from the optional SECTION
032
parameter. The __eh_frame section will be dumped by default.
033
034
-e, --english
035
Print dwarf tags and attributes in a more readable format instead
036
of using the DWARF TAG_ and AT_ definitions.
037
038
--file-stats[=size]
039
Show file composition statistics for any input files. Each file's
040
contents are analyzed and broken down into byte counts for the
041
following categories: symbol table, string table, text and code,
042
DWARF debug information, STABS debug information, and other. When
043
multiple files are specified, byte count totals for each category
044
will be displayed at the end of the table. Specify the optional
045
'size' argument to show all byte count results using unit suffixes:
046
Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte. This
047
option can be useful in tracking the size and makeup of mach-o
048
binary files, and also allows easy comparison between DWARF and
049
STABS built binaries and related object files.
050
051
-f PATTERN, --find=PATTERN
052
Search for the exact text PATTERN in the .debug_pubnames section
053
and print the matching debug information entries. Use the --regex
054
option to have PATTERN become a regular expression for more
055
flexible pattern matching.
056
057
When there is no .debug_pubnames section or the name of the DIE you
058
are looking for is not found in the .debug_pubnames section, try
059
using the slower but more complete --name option.
060
061
-F, --show-form
062
Show DWARF form types after the DWARF attribute types.
063
064
-h, -?, --help
065
Show help and usage for this command.
066
067
-i, --ignore-case
068
Ignore case distinctions in when finding by name using strings or
069
regular expressions.
070
071
-n PATTERN, --name=PATTERN
072
Find and print all DIE entries whose name (DW_AT_name attribute)
073
matches the exact text in PATTERN. Use the --regex option to
074
have PATTERN become a regular expression for more flexible pattern
075
matching.
076
077
--lookup=ADDRESS
078
Lookup ADDRESS in the debug information and print out any available
079
file, function, block and line table details.
080
081
-o PATH, --out-file=PATH
082
Redirect output to a file specified by PATH.
083
084
-p, --show-parents
085
Show a DIE's parents when using the --debug-info=OFFSET, --find,
086
and --name options.
087
088
-r N, --recurse-depth=N
089
Only recurse to a child depth of N when displaying the DWARF
090
information.
091
092
-u, --uuid
093
Show the UUID for each architecture.
094
095
-x, --regex
096
Treat any PATTERN strings as regular expressions when searching
097
instead of just as an exact string match.
098
099
-v, --verbose
100
Display verbose information when dumping. This can help to debug
101
DWARF issues.
102
103
--verify
104
Verify the structure of the DWARF information by verifying the
105
compile unit chains, die relationships graph, and address ranges.
106
107
--version
108
Display the current version and build date of the dwarfdump binary.
109
110
--debug-abbrev
111
--debug-aranges
112
--debug-frame[=OFFSET]
113
--debug-info[=OFFSET]
114
--debug-inlined
115
--debug-line[=OFFSET]
116
--debug-macinfo[=OFFSET]
117
--debug-pubnames[=PATTERN]
118
--debug-pubtypes[=PATTERN]
119
--debug-str
120
--apple-names[=PATTERN]
121
--apple-types[=PATTERN]
122
--apple-namespaces[=PATTERN]
123
--apple-objc[=PATTERN]
124
Dump the specified DWARF section by name. Only the .debug_info
125
section is disassembled by default. Some entries support adding a
126
'=OFFSET' as a way to provide an optional offset of the exact entry
127
to dump within the respective section. When an OFFSET is provided,
128
only the entry at that offset will be dumped, else the entire
129
section will be dumped. Some options support an optional '=PATTERN'
130
parameter that will search the section for an entry with a matching
131
name. Children of items at OFFSETs can be dumped by also using the
132
--show-children option where applicable.
