struct DWARFDebugMacro::MacroHeader

Declaration

struct DWARFDebugMacro::MacroHeader { /* full declaration omitted */ };

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugMacro.h:28

Member Variables

public uint16_t Version = 0

Macro version information number.

public uint8_t Flags = 0

The bits of the flags field are interpreted as a set of flags, some of which may indicate that additional fields follow. The following flags, beginning with the least significant bit, are defined: offset_size_flag: If the offset_size_flag is zero, the header is for a 32-bit DWARF format macro section and all offsets are 4 bytes long; if it is one, the header is for a 64-bit DWARF format macro section and all offsets are 8 bytes long. debug_line_offset_flag: If the debug_line_offset_flag is one, the debug_line_offset field (see below) is present. If zero, that field is omitted. opcode_operands_table_flag: If the opcode_operands_table_flag is one, the opcode_operands_table field (see below) is present. If zero, that field is omitted.

public uint64_t DebugLineOffset

debug_line_offset An offset in the .debug_line section of the beginning of the line number information in the containing compilation unit, encoded as a 4-byte offset for a 32-bit DWARF format macro section and an 8-byte offset for a 64-bit DWARF format macro section.
