Expand description
A row in the line number table that corresponds to a machine instruction.
Fields
address_offset: u64
The offset of the instruction from the start address of the sequence.
op_index: u64
The index of an operation within a VLIW instruction.
The index of the first operation is 0. Set to 0 for non-VLIW instructions.
file: FileId
The source file corresponding to the instruction.
line: u64
The line number within the source file.
Lines are numbered beginning at 1. Set to 0 if there is no source line.
column: u64
The column number within the source line.
Columns are numbered beginning at 1. Set to 0 for the “left edge” of the line.
discriminator: u64
An additional discriminator used to distinguish between source locations. This value is assigned arbitrarily by the DWARF producer.
is_statement: bool
Set to true if the instruction is a recommended breakpoint for a statement.
basic_block: bool
Set to true if the instruction is the beginning of a basic block.
prologue_end: bool
Set to true if the instruction is a recommended breakpoint at the entry of a function.
epilogue_begin: bool
Set to true if the instruction is a recommended breakpoint prior to the exit of a function.
isa: u64
The instruction set architecture of the instruction.
Set to 0 for the default ISA. Other values are defined by the architecture ABI.
