Public Attributes
uint64_t	TotalLength
	The size in bytes of the statement information for this compilation unit (not including the total_length field itself).
dwarf::FormParams	FormParams
	Version, address size (starting in v5), and DWARF32/64 format; these parameters affect interpretation of forms (used in the directory and file tables starting with v5).
uint64_t	PrologueLength
	The number of bytes following the prologue_length field to the beginning of the first byte of the statement program itself.
uint8_t	SegSelectorSize
	In v5, size in bytes of a segment selector.
uint8_t	MinInstLength
	The size in bytes of the smallest target machine instruction.
uint8_t	MaxOpsPerInst
	The maximum number of individual operations that may be encoded in an instruction.
uint8_t	DefaultIsStmt
	The initial value of theis_stmtregister.
int8_t	LineBase
	This parameter affects the meaning of the special opcodes. See below.
uint8_t	LineRange
	This parameter affects the meaning of the special opcodes. See below.
uint8_t	OpcodeBase
	The number assigned to the first special opcode.
ContentTypeTracker	ContentTypes
	This tracks which optional file format content types are present.
std::vector< uint8_t >	StandardOpcodeLengths
std::vector< DWARFFormValue >	IncludeDirectories
std::vector< FileNameEntry >	FileNames
