pub struct LineNumberRow { /* fields omitted */ }
A row in the line number program's resulting matrix.
"The program-counter value corresponding to a machine instruction
generated by the compiler."
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.
The address and op_index registers, taken together, form an operation
pointer that can reference any individual operation with the
instruction stream.
"An unsigned integer indicating the identity of the source file
corresponding to a machine instruction."
The source file corresponding to the current machine instruction.
"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."
"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."
"A boolean indicating that the current instruction is a recommended
breakpoint location. A recommended breakpoint location is intended to
“represent” a line, a statement and/or a semantically distinct subpart
of a statement."
"A boolean indicating that the current instruction is the beginning of a
basic block."
"A boolean indicating that the current address is that of the first byte
after the end of a sequence of target machine instructions. end_sequence
terminates a sequence of lines; therefore other information in the same
row is not meaningful."
"A boolean indicating that the current address is one (of possibly many)
where execution should be suspended for an entry breakpoint of a
function."
"A boolean indicating that the current address is one (of possibly many)
where execution should be suspended for an exit breakpoint of a
function."
Tag for the current instruction set architecture.
An unsigned integer whose value encodes the applicable instruction set
architecture for the current instruction.
The encoding of instruction sets should be shared by all users of a
given architecture. It is recommended that this encoding be defined by
the ABI authoring committee for each architecture.
"An unsigned integer identifying the block to which the current
instruction belongs. Discriminator values are assigned arbitrarily by
the DWARF producer and serve to distinguish among multiple blocks that
may all be associated with the same source file, line, and column. Where
only one block exists for a given source position, the discriminator
value should be zero."
