Basic block.

Basic block is piece of code, that has single entry and single exit. It can be seen as a container for instructions. Also, basic blocks are nodes of control flow graphs.

The following invariants must be preserved:

  • there is no known jump in the program, that points to an instruction that is not a leader of a basic block;
  • any jump instruction is a terminator of some basic block;
  • each basic block consists of at least one instruction.
type t = block
include sig ... end
val sexp_of_t : t -> Sexplib.Sexp.t
val create : mem -> (mem * insn) list -> t

create mem insn creates a block Preconditions:

  • insns <> []
val addr : t -> addr

addr block = Memory.min_addr (memory block) address of the first instruction

val memory : t -> mem

memory blk a memory region, occupied by a block

val leader : t -> insn

leader blk the first instruction

val terminator : t -> insn

terminator blk last instruction of the block

val insns : t -> (mem * insn) list

insns blk returns a list of block instructions.

Since block contains a region of memory, that is not regular, the block itself is also non-regular. But it is, at least, printable.
