Module Builtins_malloc

module Builtins_malloc: sig .. end

Dynamic allocation related builtins. Most functionality is exported as builtins.

val fold_dynamic_bases : (Base.t -> Value_types.Callstack.t -> 'a -> 'a) -> 'a -> 'a

fold_dynamic_bases f init folds f to each dynamically allocated base, with initial accumulator init. Note that this also includes bases created by alloca and VLAs.

val alloc_size_ok : Cvalue.V.t -> Alarmset.status

val free_automatic_bases : Value_types.Callstack.t -> Cvalue.Model.t -> Cvalue.Model.t

Performs the equivalent of free for each location that was allocated via alloca() in the current function (as per Eva_utils.call_stack ()). This function must be called during finalization of a function call.

val freeable : Cvalue.V.t -> Abstract_interp.truth

Evaluates the ACSL predicate \freeable(value): holds if and only if the value points to an allocated memory block that can be safely released using the C function free. Note that \freeable(\null) does not hold, despite NULL being a valid argument to the C function free.
