Expand description

An object file.

Required Associated Types§

A segment in the object file.

An iterator over the segments in the object file.

A section in the object file.

An iterator over the sections in the object file.

A COMDAT section group in the object file.

An iterator over the COMDAT section groups in the object file.

A symbol in the object file.

An iterator over symbols in the object file.

A symbol table in the object file.

An iterator over dynamic relocations in the file.

The first field in the item tuple is the address that the relocation applies to.

Required Methods§

Get the architecture type of the file.

Return true if the file is little endian, false if it is big endian.

Return true if the file can contain 64-bit addresses.

Return the kind of this object.

Get an iterator over the segments in the file.

Like Self::section_by_name, but allows names that are not UTF-8.

Get the section at the given index.

The meaning of the index depends on the object file.

For some object files, this requires iterating through all sections.

Returns an error if the index is invalid.

Get an iterator over the sections in the file.

Get an iterator over the COMDAT section groups in the file.

Get the symbol table, if any.

Get the debugging symbol at the given index.

The meaning of the index depends on the object file.

Returns an error if the index is invalid.

Get an iterator over the debugging symbols in the file.

This may skip over symbols that are malformed or unsupported.

For Mach-O files, this does not include STAB entries.

Get the dynamic linking symbol table, if any.

Only ELF has a separate dynamic linking symbol table.

Get an iterator over the dynamic linking symbols in the file.

This may skip over symbols that are malformed or unsupported.

Only ELF has separate dynamic linking symbols. Other file formats will return an empty iterator.

Get the dynamic relocations for this file.

Symbol indices in these relocations refer to the dynamic symbol table.

Only ELF has dynamic relocations.

Get the imported symbols.

Get the exported symbols that expose both a name and an address.

Some file formats may provide other kinds of symbols, that can be retrieved using the lower-level API.

Return true if the file contains debug information sections, false if not.

Get the base address used for relative virtual addresses.

Currently this is only non-zero for PE.

Get the virtual address of the entry point of the binary

File flags that are specific to each file format.

Provided Methods§

Get the endianness of the file.

Get the section named section_name, if such a section exists.

If section_name starts with a ‘.’ then it is treated as a system section name, and is compared using the conventions specific to the object file format. This includes:

  • if “.debug_str_offsets” is requested for a Mach-O object file, then the actual section name that is searched for is “__debug_str_offs”.
  • if “.debug_info” is requested for an ELF object file, then “.zdebug_info” may be returned (and similarly for other debug sections).

For some object files, multiple segments may contain sections with the same name. In this case, the first matching section will be used.

This method skips over sections with invalid names.

Construct a map from addresses to symbol names.

The map will only contain defined text and data symbols. The dynamic symbol table will only be used if there are no debugging symbols.

Construct a map from addresses to symbol names and object file names.

This is derived from Mach-O STAB entries.

The UUID from a Mach-O LC_UUID load command.

The build ID from an ELF NT_GNU_BUILD_ID note.

The filename and CRC from a .gnu_debuglink section.

The filename and build ID from a .gnu_debugaltlink section.

The filename and GUID from the PE CodeView section
