odump - Dumps selected parts of an object file
odump [-a c[m] f g[p] hi j[f|s] l[a|4|8] orstxz
D[cghlmrst] FOPRV X[p|x] flag_modifiers] file1...fileN
This command works for object files and archives of object
files. It accepts one or more of the following options:
Dumps the archive header for each member of an archive
file. Dumps the string table (local and external
strings). Dumps the contents of the section. Dumps the
file header. Dumps the global symbols from the symbol
table of an archive file. Dumps gp range information.
Dumps section headers. Dumps the symbolic information
header. Dumps compact relocations stored in the section.
In addition to dumping information associated with -j,
dumps compact relocations that are predicted and not
stored. Dumps brief statistics on the compact relocations
stored in the section. Dumps line numbers. Dumps the
contents of a literal section; with x specifying the section
to dump, as follows: Dumps the 4-byte literal section.
Dumps the 8-byte literal section. Dumps the literal
address section (.lita). Dumps the optional header.
Dumps relocation information. Dumps section contents.
Dumps symbol table entries. Indexed symbol table entries
only can be dumped by using the -t index and +t index
options: Dumps indexed symbol table entries in a range
starting at the specified entry (index) and ending at the
last entry or the entry specified by +t. Dumps symbol
table entries in a range starting at the first entry or
the entry specified by -t and ending at the entry specified
by +t. Dumps the auxiliary symbol table. Dumps line
number entries for the specified function (name). A range
of line number entries can be dumped by using -z name,number
and +z number options: Dumps a range of line number
entries starting at number for the named function (name)
and ending at the last line number or the line number
specified by +z. Dumps line numbers for a specified
range. The range starts at either the name or number
specified by -z. The range ends with the number specified
by +z.
The name and number specified by a -z modifier can
be separated by a blank instead of a comma. Displays
the section for each file specified. This
section contains basic information describing where
other sections related to dynamic loading are
located and the size of those sections. You can use
the following modifiers with the -D option: Displays
the section for each file specified. This
conflict table lists symbols whose normal definition
is overridden at run time. Displays the section
for each file specified. The GOT (global offset
table) contains the run-time addresses of each
symbol exported or imported by the shared object.
Displays the section for each file specified. This
hash table contains entries for each name in the
section and is used for fast lookup of symbols.
Displays the section for each file specified. This
section contains a list of the shared libraries
needed by this object. Displays the section for
each file specified. The msym table contains
entries corresponding to each symbol in the section.
Each entry contains the symbol's hash value
and an index into the dynamic relocation table. The
msym table is used to speed up loader processing
and reduce the dynamic memory allocated by the
loader. Displays the dynamic relocation section
(.rel.dyn) for each file specified. Each relocation
entry represents a reference to a symbol in a
shared library. Displays the section for each file
specified. This section contains strings referenced
by other dynamic loading sections. Displays the
section for each file specified. This is a table of
external symbols in a shared object. Dumps the
file descriptor table. Dumps optimization symbols.
Dumps the procedure descriptor table. Dumps the
relative file descriptor table. Displays the version
of the odump command. Dumps the exception
procedure table. Enhances the -Xp output to show
scope table information for each entry. The -Xx
option must be used with the -Xp option.
The following modifiers (flag_modifiers) can be used with
odump command options: Dumps a section or a range of sections.
The range starts either at the first section or at
number (if specified). The range ends at either the last
section or the section you specify with +d. This modifier
can be used with -r and -s. Dumps sections in the range
beginning with either the first section or the section
specified by -d. The range ends with either the last section
or the section specified by +d. This modifier can be
used with -r and -s. Dumps information about only the
specified name. You can use this modifier with -h, -l,
-r, and -s. Does not display headers. The modifier can be
used with all of the command options. Underlines the name
of the file for emphasis. The modifier can be used with
all of the command options. Dumps information symbolically
rather than numerically (for example, Static rather
than 0X02). This modifier can be used with -a, -cm, -f,
-gp, -la, -o, -r, -t, -x, and -O.
Optionally, an option and its modifier can be separated by
using blanks.
[Tru64 UNIX] The DEC C++ compiler encodes type information
in function, template, variable, and virtual table
names to enable type-safe linkages. This encoding is
referred to as "name mangling". The following options can
be used with the -r, -t, and -P options to instruct the
odump command to print either the original name (that is,
the demangled name), the mangled name, or both names by
specifying one of the following options. By default,
odump shows the demangled names only. [Tru64
UNIX] Prints only the mangled name. [Tru64 UNIX] Prints
both the mangled and the demangled names.
The odump command tries to format information in a helpful
way, displaying information in character, hexadecimal,
octal, or decimal, as appropriate.
The odump command dumps selected parts of each file that
is specified. For details on the object file parts presented
in the odump output, see the Assembly Language Programmer's
Guide.
