val boolean_empty : Context.t -> boolean

Empty denotes that the concretization has no value (or it is the concrete value representing the absence of value). Note that this does not necessarily imply that some error occured; for instance the offset of an uninitialized pointer can be represented with empty. Emptyness testing is a simple way of communicating between domains.

val sizeof : (block, offset) Sig.Context_Arity_Forward(Context).ar1

Size of a block in bytes

val concat : (block, block, block) Sig.Context_Arity_Forward(Context).ar2

Concatenates two blocks

val load : 
  size:Units.In_bits.t ->
  (block, offset, Value.binary) Sig.Context_Arity_Forward(Context).ar2

Loads (extracts) a value of a fixed size at a given index from a block

val store : 
  size:Units.In_bits.t ->
  (block, offset, Value.binary, block) Sig.Context_Arity_Forward(Context).ar3

Stores (writes) a fixed size value of a given index in a block

val binary_to_block : 
  size:Units.In_bits.t ->
  (Value.binary, block) Sig.Context_Arity_Forward(Context).ar1

Converts a fixed size value to a block

val initial : Context.t -> Units.In_bytes.t -> block

Create an initial region of size int (in bytes). Only meaning full for memories that are a single contiguous region

val unknown : level:int -> Context.t -> block

val block_empty : Context.t -> block

An empty region, with no bound offset.

val block_unknown_typed : Context.t -> Types.TypedC.typ -> block

Returns an unknown block value with a given type.

val check_type : 
  Context.t ->
  Types.TypedC.typ ->
  block ->
  block Types.Type_check_tree.t

Type check a block value
