/// @brief Base class for instruction visitors
///
-/// Instruction visitors are used when you want to perform different action for
-/// different kinds of instruction without without having to use lots of casts
-/// and a big switch statement (in your code that is).
+/// Instruction visitors are used when you want to perform different actions
+/// for different kinds of instructions without having to use lots of casts
+/// and a big switch statement (in your code, that is).
///
/// To define your own visitor, inherit from this class, specifying your
/// new type for the 'SubClass' template parameter, and "override" visitXXX
-/// functions in your class. I say "overriding" because this class is defined
+/// functions in your class. I say "override" because this class is defined
/// in terms of statically resolved overloading, not virtual functions.
///
/// For example, here is a visitor that counts the number of malloc
/// /// Declare the class. Note that we derive from InstVisitor instantiated
/// /// with _our new subclasses_ type.
/// ///
-/// struct CountMallocVisitor : public InstVisitor<CountMallocVisitor> {
+/// struct CountAllocaVisitor : public InstVisitor<CountAllocaVisitor> {
/// unsigned Count;
-/// CountMallocVisitor() : Count(0) {}
+/// CountAllocaVisitor() : Count(0) {}
///
-/// void visitMallocInst(MallocInst &MI) { ++Count; }
+/// void visitAllocaInst(AllocaInst &AI) { ++Count; }
/// };
///
/// And this class would be used like this:
-/// CountMallocVistor CMV;
-/// CMV.visit(function);
-/// NumMallocs = CMV.Count;
+/// CountAllocaVisitor CAV;
+/// CAV.visit(function);
+/// NumAllocas = CAV.Count;
///
/// The defined has 'visit' methods for Instruction, and also for BasicBlock,
-/// Function, and Module, which recursively process all conained instructions.
+/// Function, and Module, which recursively process all contained instructions.
///
/// Note that if you don't implement visitXXX for some instruction type,
/// the visitXXX method for instruction superclass will be invoked. So
/// if instructions are added in the future, they will be automatically
-/// supported, if you handle on of their superclasses.
+/// supported, if you handle one of their superclasses.
///
/// The optional second template argument specifies the type that instruction
/// visitation functions should return. If you specify this, you *MUST* provide
