Class BV A class representing an AST of operations culminating in a bitvector. Do not instantiate this class directly, instead use BVS or BVV to construct a symbol or value, and then use operations to construct more complicated expressions.
Function BVS Creates a bit-vector symbol (i.e., a variable).
Function BVV Creates a bit-vector value (i.e., a concrete value).

def BVS(name, size, min=None, max=None, stride=None, uninitialized=False, explicit_name=None, discrete_set=False, discrete_set_max_card=None, **kwargs): (source)

Creates a bit-vector symbol (i.e., a variable). If you want to specify the maximum or minimum value of a normal symbol that is not part of value-set analysis, you should manually add constraints to that effect. **Do not use ``min`` and ``max`` for symbolic execution.** :param name: The name of the symbol. :param size: The size (in bits) of the bit-vector. :param min: The minimum value of the symbol, used only for value-set analysis :param max: The maximum value of the symbol, used only for value-set analysis :param stride: The stride of the symbol, used only for value-set analysis :param uninitialized: Whether this value should be counted as an "uninitialized" value in the course of an analysis. :param bool explicit_name: If False, an identifier is appended to the name to ensure uniqueness. :param bool discrete_set: If True, a DiscreteStridedIntervalSet will be used instead of a normal StridedInterval. :param int discrete_set_max_card: The maximum cardinality of the discrete set. It is ignored if discrete_set is set to False or None. :returns: a BV object representing this symbol.

def BVV(value, size=None, **kwargs): (source)

Creates a bit-vector value (i.e., a concrete value). :param value: The value. Either an integer or a bytestring. If it's the latter, it will be interpreted as the bytes of a big-endian constant. :param size: The size (in bits) of the bit-vector. Optional if you provide a string, required for an integer. :returns: A BV object representing this value.
