Public Member Functions
	RelocatableBlock (block_type type, uint32_t flags=LoadAny)
uint32_t	GetSizeField () const
	Returns the 32-bit longword that stores the size of the segment plus 2 flag bits.
bool	RequiresAdditionalFlags () const
	Returns true if an additional 32-bit longword is needed for flags.
uint32_t	GetAdditionalFlags () const
	The contents of an additional 32-bit longword is needed for flags.
void	Read (Linker::Reader &rd) override
	Reads the rest of the block after the type word.
void	Write (Linker::Writer &wr) const override
	Writes the entire block into a file.
offset_t	FileSize () const override
	Returns the size of the block as stored inside a file.
void	AddExtraFields (Dumper::Region &region, const Module &module, const Hunk *hunk, unsigned index, offset_t current_offset) const override
Public Member Functions inherited from Amiga::HunkFormat::Block

Public Attributes
flag_type	flags
bool	loaded_with_additional_flags = false
Public Attributes inherited from Amiga::HunkFormat::Block
block_type	type
bool	is_executable = false
	Required because V37 executables define HUNK_DRELOC32 as HUNK_RELOC32SHORT, must block types ignore this field and it is not stored.

Protected Member Functions
virtual uint32_t	GetSize () const =0
	The actual size of the segment data, as a count of 32-bit longwords.
virtual void	ReadBody (Linker::Reader &rd, uint32_t longword_count)
	Reads the segment data (if any)
virtual void	WriteBody (Linker::Writer &wr) const
	Writes the segment data (if any)

Additional Inherited Members
Static Public Member Functions inherited from Amiga::HunkFormat::Block
static std::shared_ptr< Block >	ReadBlock (Linker::Reader &rd, bool is_executable=false)
	Reads a single block from file.
