DWARFDUMP DWARFDUMP
NAMEdwarfdump - dumps DWARF debug information of an ELF object
SYNOPSISdwarfdump [-abcdefilmoprsvy] [-t{afv}] [-uobjectfile] filename
DESCRIPTION
The dwarfdump command prints DWARF sections as requested by specific
options. With no options nothing prints!
The format is intended to be human readable. If a script is to parse the
output, the -d option is useful.
The format may change from release to release, so it is unwise to depend
too heavily on the format.
The dwarfdump command accepts one or more of the following options:
-a Dumps all sections. Same as -bcfilmoprsy -tfv.
-b Dumps the .debug_abbrev section.
-c Dumps the .debug_loc section.
-d Dense mode. Each die information of the .debug_info section is
printed in one-line format. This option does not imply -i.
-e Ellipsis mode. Short names for DW_TAG_* and DW_ATTR_* are used
in the output for the .debug_info section.
-f Dumps the .debug_frame section.
-h Dumps the C++ exception handling section (MIPS_EH_REGION). If
-v is specified in addition to -h , the exception handling
supplemental table (MIPS_EH_REGION_SUPP section) is also
printed.
The fields printed out for the exception table are (in the
following order): region number; kind which can take one three
values 't' for try block region, 'c' for cleanup region and 'e'
for exception specification region; the low offset; the high
offset; region number of parent.
The supplemental information printed for try block regions
include: the handler address; flags; type_info (a structure
describing the type) address. The supplement information is
repeated for every handler assoicated with the try block in a
new line.
The supplemental information printed for exception
specification supplement include: the type_info address and the
flags.

The supplemental information printed for cleanup supplement
include: the address of the destructor or delete routine;
flags; the address of the object and the following fields if
present (the presence is indicated in the flags field): this
parameter offset; number of elements of the array object; size
of each element; the offset of the conditional flag; and the
address of the guard variable.

-i Dumps the .debug_info section.
-l Dumps the .debug_line information.
-m Dumps the .debug_macinfo section.
-o Dumps the .reloc_debug_* sections.
-p Dumps the .debug_pubnames section.
-r Dumps the .debug_aranges section.
-s Dumps .debug_string section.
-ta Same as -tfv.
-tf Dumps the .debug_static_funcs section.
-tv Dumps the .debug_static_vars section.
-uofile
Restricts the dumping of sections to the named object file
only.
-v Verbose mode. Shows more detailed information. Mor detailed
information about the .debug_frame section prints if 2 or 3 -v

-w Dumps the .debug_weaknames section.
-y Dumps the .debug_types section.
