Member Data Documentation

◆ Address

uint64_t llvm::DWARFDebugLine::Row::Address

The program-counter value corresponding to a machine instruction generated by the compiler.

Definition at line 148 of file DWARFDebugLine.h.

Referenced by llvm::DWARFDebugLine::LineTable::clear(), llvm::DWARFContext::getLineInfoForAddressRange(), orderByAddress(), and llvm::DWARFDebugLine::LineTable::parse().

◆ BasicBlock

uint8_t llvm::DWARFDebugLine::Row::BasicBlock

A boolean indicating that the current instruction is the beginning of a basic block.

Definition at line 168 of file DWARFDebugLine.h.

◆ Column

uint16_t llvm::DWARFDebugLine::Row::Column

An unsigned integer indicating a column number within a source line.

Columns are numbered beginning at 1. The value 0 is reserved to indicate that a statement begins at the 'left edge' of the line.

◆ Discriminator

uint32_t llvm::DWARFDebugLine::Row::Discriminator

An unsigned integer representing the DWARF path discriminator value for this location.

Definition at line 162 of file DWARFDebugLine.h.

Referenced by llvm::DWARFDebugLine::LineTable::getFileLineInfoForAddress().

◆ EndSequence

uint8_t llvm::DWARFDebugLine::Row::EndSequence

A boolean indicating that the current address is that of the first byte after the end of a sequence of target machine instructions.

Definition at line 168 of file DWARFDebugLine.h.

Referenced by llvm::DWARFDebugLine::LineTable::clear().

◆ EpilogueBegin

uint8_t llvm::DWARFDebugLine::Row::EpilogueBegin

A boolean indicating that the current address is one (of possibly many) where execution should be suspended for an exit breakpoint of a function.

Definition at line 168 of file DWARFDebugLine.h.

◆ File

uint16_t llvm::DWARFDebugLine::Row::File

An unsigned integer indicating the identity of the source file corresponding to a machine instruction.

Definition at line 159 of file DWARFDebugLine.h.

Referenced by llvm::DWARFDebugLine::LineTable::getFileLineInfoForAddress(), and llvm::DWARFContext::getLineInfoForAddressRange().

◆ Isa

uint8_t llvm::DWARFDebugLine::Row::Isa

An unsigned integer whose value encodes the applicable instruction set architecture for the current instruction.

Definition at line 165 of file DWARFDebugLine.h.

◆ IsStmt

uint8_t llvm::DWARFDebugLine::Row::IsStmt

A boolean indicating that the current instruction is the beginning of a statement.

Definition at line 168 of file DWARFDebugLine.h.

◆ Line

uint32_t llvm::DWARFDebugLine::Row::Line

An unsigned integer indicating a source line number.

Lines are numbered beginning at 1. The compiler may emit the value 0 in cases where an instruction cannot be attributed to any source line.

Definition at line 152 of file DWARFDebugLine.h.

Referenced by llvm::DWARFDebugLine::LineTable::getFileLineInfoForAddress(), and llvm::DWARFContext::getLineInfoForAddressRange().

◆ PrologueEnd

uint8_t llvm::DWARFDebugLine::Row::PrologueEnd

A boolean indicating that the current address is one (of possibly many) where execution should be suspended for an entry breakpoint of a function.
