22 Chapter 5. objdump

-adjust-vma=offset

When dumping information, ﬁrst add offset to all the section addresses. This is useful if the

section addresses do not correspond to the symbol table, which can happen when putting sections

at particular addresses when using a format which can not represent section addresses, such as

a.out.

-b bfdname

-target=bfdname

Specify that the object-code format for the object ﬁles is bfdname. This option may not be

necessary; objdump can automatically recognize many formats.

For example,

objdump -b oasys -m vax -h fu.o

displays summary information from the section headers (-h) of fu.o, which is explicitly iden-

tiﬁed (-m) as a VAX object ﬁle in the format produced by Oasys compilers. You can list the

formats available with the -i option. Section 16.1 Target Selection, for more information.

-C

-demangle[=style]

Decode (demangle) low-level symbol names into user-level names. Besides removing any initial

underscore prepended by the system, this makes C++ function names readable. Different compil-

ers have different mangling styles. The optional demangling style argument can be used to choose

an appropriate demangling style for your compiler. Chapter 10 c++ﬁlt, for more information on

demangling.

-g

-debugging

Display debugging information. This attempts to parse debugging information stored in the ﬁle

and print it out using a C like syntax. Only certain types of debugging information have been

implemented. Some other types are supported by readelf -w. Chapter 15 readelf .

-e

-debugging-tags

Like -g, but the information is generated in a format compatible with ctags tool.

-d

-disassemble

Display the assembler mnemonics for the machine instructions from objfile. This option only

disassembles those sections which are expected to contain instructions.

-D

-disassemble-all

Like -d, but disassemble the contents of all sections, not just those expected to contain instruc-

tions.

-prefix-addresses

When disassembling, print the complete address on each line. This is the older disassembly

format.
