DWARFDUMP                                                            DWARFDUMP



NAME
     dwarfdump - dumps DWARF debug information of an ELF object

SYNOPSIS
     dwarfdump [-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.



                                                                        Page 1

               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.

               For more details, see /usr/include/cmplrs/exception_table.h


          -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
               options are given.

          -w   Dumps the .debug_weaknames section.

          -y   Dumps the .debug_types section.
