dmp960/gdmp960 Dumper/Disassembler

The dumper/disassembler provides access to binary information in executable or relocatable object files. The dmp960/gdmp960 utility combines the features of traditional disassemblers and dumpers.

The invocation command is:

dmp960 | gdmp960 [ option ]... file...

The options (listed below) either select which part of the object file to display, or control the formatting of the display. The default selection option is d, which dumps the sections of an object file that are loaded in target memory. Each option must be preceded by a - character. (On DOS, you can also use a / character.)

Options

• a
  Dump (disassemble) all the sections in an object file. Use this to examine the raw DWARF information in a file. The default is to dump only those sections loaded in target memory.
• c
  Dump the string table.
• D
  Dump section contents as if it were a data section, in hexadecimal bytes. Applies only to the d option.
• d
  Dump the contents of all sections loaded into target memory. This is the default. In the absence of conflicting formatting options, text sections are disassembled into assembly language instructions, and data sections are dumped as hexadecimal bytes.
• F function
  Disassemble only the named COFF or ELF function. Applies only to the d option.
• f
  Display the file header.
• g[arg]…
  Display one or more .debug_* sections. arg can be:
  i dump .debug_info
  l dump .debug_line
  f dump .debug_frame
  p dump .debug_pubnames
  a dump .debug_aranges
  m dump .debug_macinfo
  A dump all .debug_* sections
• h
  Displays the COFF section headers.
• help
  Prints help information to stdout and exits.
• i
  Display the COFF optional header.
• l
  Displays COFF line number entries.
• m
  Displays the memory map (section layout) of the file.
• n section
  Dumps only the named section. Applies to whatever option is in effect.
• o
  Prints addresses in octal instead of hexadecimal.
• p
  Suppresses headers. Prints just the information requested.
• q
  Queries the file and display its type.
• r
  Dumps relocation entries.
• s
  Performs symbolic disassembly. Displays labels symbolically instead of numerically whenever possible. Applies only to the d option.
• T
  Dumps section contents as if it were a text section. (Disassembles it into assembly language instructions.) Applies only to the d option.
• t
  Dumps the b.out or COFF symbol table.
• V
  Prints version information to stdout and continues.
• v960
  Prints version information to stdout and exits.
• x
  Suppresses symbolic translation of COFF symbol types and storage classes. Prints a symbol's type and storage class numerically. Applies only to the t option.
• z
  Suppresses zeros when displaying text section contents. The default is to translate zeros into .word directives when disassembling text sections. Applies only to the d option.
