NAME
dwarfdump -- dump DWARF debug information.
SYNOPSIS
dwarfdump [options] file1 file2 ...
DESCRIPTION
For each operand that names a mach-o or 32 bit ELF file, dwarfdump disassembles the DWARF data found within the file. Only the .debug_info
section is disassembled unless one of the --debug-XXXX or --all options are specified.
The following options are available:
-a, --all
Disassemble all supported DWARF sections.
--arch=ARCH
Dump DWARF debug information for the specified CPU architecture. Architectures may be specified by name or by number. This option
can be specified multiple times, once for each desired architecture. All cpu architectures will be disassembled by default.
-c, --show-children
Show a DIE's children when using the --debug-info=OFFSET, --find, and --name options.
-e, --english
Print dwarf tags and attributes in a more readable format instead of using the DWARF TAG_ and AT_ definitions.
--eh-frame[=SECTION]
Dump exception handling frame information from the optional SECTION parameter. The __eh_frame section will be dumped by default.
--file-stats[=size]
Show file composition statistics for any input files. Each file's contents are analyzed and broken down into byte counts for the
following categories: symbol table, string table, text and code, DWARF debug information, STABS debug information, and other. When
multiple files are specified, byte count totals for each category will be displayed at the end of the table. Specify the optional
'size' argument to show all byte count results using unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte. This
option can be useful in tracking the size and makeup of mach-o binary files, and also allows easy comparison between DWARF and STABS
built binaries and related object files.
-f PATTERN, --find=PATTERN
Search for the exact text PATTERN in the .debug_pubnames section and print the matching debug information entries. Use the --regex
option to have PATTERN become a regular expression for more flexible pattern matching.
When there is no .debug_pubnames section or the name of the DIE you are looking for is not found in the .debug_pubnames section, try
using the slower but more complete --name option.
-F, --show-form
Show DWARF form types after the DWARF attribute types.
-h, -?, --help
Show help and usage for this command.
-i, --ignore-case
Ignore case distinctions in when finding by name using strings or regular expressions.
-n -PATTERN, --name=PATTERN
Find and print all DIE entries whose name (DW_AT_name attribute) matches the exact text in PATTERN. Use the --regex option to have
PATTERN become a regular expression for more flexible pattern matching.
--lookup=ADDRESS
Lookup ADDRESS in the debug information and print out the file, function, block and line table details.
-o PATH, --out-file=PATH
Redirect output to a file specified by PATH.
-p, --show-parents
Show a DIE's parent DIE objects when using the --debug-info=OFFSET, --find, and --name options.
-r N, --recurse-depth=N
Only recurse to a child depth of N when displaying the DWARF information.
-x, --regex
Treat any PATTERN strings as regular expressions when searching instead of just as an exact string match.
-u, --uuid
Show the UUID for each architecture.
-v, --verbose
Display verbose information when dumping. This can help to debug DWARF issues.
--verify
Verify the structure of the DWARF information by verifying the compile unit chains, die relationships graph, and address ranges.
--version
Display the current version and build date of the dwarfdump binary.
--debug-abbrev, --debug-aranges, --debug-frame[=OFFSET], --debug-info[=OFFSET], --debug-inlined, --debug-line[=OFFSET],
--debug-macinfo[=OFFSET], --debug-pubnames[=PATTERN], --debug-pubtypes[=PATTERN], --debug-str
Dump the specified DWARF section by name. Only the .debug_info section is disassembled by default. Some entries support adding a
'=OFFSET' as a way to provide an optional offset of the exact entry to dump within the respective section. When an OFFSET is pro-
vided, only the entry at that offset will be dumped, else the entire section will be dumped. Some options support an optional '=PAT-
TERN' parameter that will search the section for an entry with a matching name. Children of items at OFFSETs can be dumped by also
using the --show-children option where applicable.
