Create a new symbol with a unique 'name'.

We resort to conjured symbols when we cannot construct a derived symbol. The advantage of symbols derived/built from other symbols is that we preserve the relation between related(or even equivalent) expressions, so conjured symbols should be used sparingly.

◆ evalCast()

SVal SValBuilder::evalCast	(	SVal	V,
		QualType	CastTy,
		QualType	OriginalTy
	)

Cast a given SVal to another SVal using given QualType's.

Parameters

V	– SVal that should be casted.
CastTy	– QualType that V should be casted according to.
OriginalTy	– QualType which is associated to V. It provides additional information about what type the cast performs from.

Returns: the most appropriate casted SVal. Note: Many cases don't use an exact OriginalTy. It can be extracted from SVal or the cast can performs unconditionaly. Always pass OriginalTy! It can be crucial in certain cases and generates different results. FIXME: If OriginalTy.isNull() is true, then cast performs based on CastTy only. This behavior is uncertain and should be improved.
