Public Attributes
object::SectionedAddress Address
The program-counter value corresponding to a machine instruction generated by the compiler and section index pointing to the section containg this PC.
uint32_t Line
An unsigned integer indicating a source line number.
uint16_t Column
An unsigned integer indicating a column number within a source line.
uint16_t File
An unsigned integer indicating the identity of the source file corresponding to a machine instruction.
uint32_t Discriminator
An unsigned integer representing the DWARF path discriminator value for this location.
uint8_t Isa
An unsigned integer whose value encodes the applicable instruction set architecture for the current instruction.
uint8_t OpIndex
An unsigned integer representing the index of an operation within a VLIW instruction.
uint8_t IsStmt: 1
A boolean indicating that the current instruction is the beginning of a statement.
uint8_t BasicBlock: 1
A boolean indicating that the current instruction is the beginning of a basic block.
uint8_t EndSequence: 1
A boolean indicating that the current address is that of the first byte after the end of a sequence of target machine instructions.
uint8_t PrologueEnd: 1
A boolean indicating that the current address is one (of possibly many) where execution should be suspended for an entry breakpoint of a function.
uint8_t EpilogueBegin: 1
A boolean indicating that the current address is one (of possibly many) where execution should be suspended for an exit breakpoint of a function.

◆ Address

The program-counter value corresponding to a machine instruction generated by the compiler and section index pointing to the section containg this PC.

If relocation information is present then section index is the index of the section which contains above address. Otherwise this is object::SectionedAddress::Undef value.

◆ EpilogueBegin

uint8_t llvm::DWARFDebugLine::Row::EpilogueBegin

◆ Line

uint32_t llvm::DWARFDebugLine::Row::Line

◆ OpIndex

uint8_t llvm::DWARFDebugLine::Row::OpIndex

An unsigned integer representing the index of an operation within a VLIW instruction.

The index of the first operation is 0. For non-VLIW architectures, this register will always be 0.
