Public Attributes
uint64_t	LowPC
	Sequence describes instructions at address range [LowPC, HighPC) and is described by line table rows [FirstRowIndex, LastRowIndex).
uint64_t	HighPC
uint64_t	SectionIndex
	If relocation information is present then this is the index of the section which contains above addresses.

unsigned	LastRowIndex
bool	Empty

Detailed Description

Represents a series of contiguous machine instructions.

Line table for each compilation unit may consist of multiple sequences, which are not guaranteed to be in the order of ascending instruction address.
