            Runs after Normalizer and Analyzer. Performs rewrites that we don't want the analyzer to see, e.g., removes
            calls to conditional methods.
            It can also take advantage of invariants learned during the Analyzer phase.

            The dataflow analysis for the method under analysis 
            </summary>
        </member>
        <member name="T:System.Compiler.ForwardDataFlowAnalysis">
            <summary>
            Implements a pretty standard data flow analysis with merging of data flow states at join
            points. 
            
            Details:
            
            At each block, we maintain two data flow states, pending, and done. Done represents the 
            dataflow state under which the block has already been analyzed, whereas Pending represent
            the state under which the block still needs to be analyzed.
            
            When a block is reached with a state, it is merged into the pending state. This merge can
            either be precise, or with weakening (includes now more possibilities than the two states
            that were merged).
            
            Once a block is dequeued for analysis, we compute the new done state, which is the merge
            of the pending state with the	old done state. There are 3 possible outcomes:
            1. The old done state completely supersedes the new pending state: no reanalysis is necessary
            2. The merge is precise, then the block needs to be analyzed only with the pending state 
               (no need to redo all cases in the done state). 
            3. The merge is imprecise (contains more possibilities than in either the pending or the old 
               done state), then we need to analyze the block using this merged state in order to account
               for these new possibilities.
              
            Another imprecision arises from the merge of pending states. This merge could be imprecise, and
            therefore at the next analysis, we could be analyzing the block under extra cases. Buckets could
            be used to avoid this. Buckets just increase the language of formulas for expressing fixpoints to
            a finite disjunction.
            
            Each block can be in one of 3 states:
            a) unenabled (block needs to be reached by more edges before we run it)
            b) enabled and in work queue (needs to be rescheduled)
            c) enabled but has been processed with latest incoming states.

            <summary>
            Decoder for CCI statements after normalization and code flattening. Provides a view of
            instructions close to CIL (.NET CLR Partition 3 document).
            The Visit method recognizes the CCI encodings for each instruction and calls
            the appropriate Visit* method.  Subclassing <c>InstructionVisitor</c> allows writing
            visitors that deal directly with only a small set of distinct instructions and without
            recursive expressions, since arguments to all instructions are variables.
            <p/>
            To make decoding simple, some MSIL instructions are split, such as ldtoken, which was
            split into three cases: LDTYPETOKEN, LDFIELDTOKEN, LDMETHODTOKEN.
            <p/>
            On the other hand, some instructions are distinguished by <c>null</c> tests; the MSIL instructions
            "ldfld" (load object field) and "ldsfld" (load static field) are modeled by the same visitor
            LDFIELD "dest := source.field" with source being <c>null</c> for a static field. Similarly, an unconditional
            branch instruction is modelled as an BRANCH with a <c>null</c> condition.
            <p/>
            The envisioned use of this class is as follows:  subclass <c>InstructionVisitor</c> and override
            each Visit* method
            (VisitCopy, VisitLoadConstant etc.) to specify the processing that you want for each instruction.
            Given a Cci statement (normalized and flattened) stat, do the appropriate processing for it by calling 
            Visit(stat, some_arg).
            <p/>
            Visit acts as a dispatcher: it recognizes the instruction encoded by stat and calls the
            appropriate Visit* method with the right arguments.  Visit stands for a top-level transfer function:
            its second argument is the argument passed to the appropriate transfer function; its result is the
            result of that transfer function.
            <p/>
            NOTE: With generics, we would have defined InstructionVisitor as Visitor&lt;A,B&gt;, where A and B
            are the argument type, respectively the result type of each transfer function.  If your transfer
            functions don't take any argument, you can pass <c>null</c>.
            Similarly, if they don't return anything, you can return <c>null</c>.
            <p/>
            See the documentation of each of the Visit* methods for more info on the format of each instruction.
            Also see the <c>SampleInstructionVisitor</c> for a full example.
            <p>
            The following conventions apply for each Visit* method:</p>
            
            <ol>
            <li>The last two arguments are the original Cci statement and the argument passed to
            Visit(Statement stat, object arg) 
            </li>
            Having the original statements allows you to attach information to it (in some hashtable) or, in rare
            cases, to look for features that are not exposed.
            <li>Each method returns an object. This is conceptually the result of the transfer function associated with
            that instruction.</li>
            <li>Each such method is called by the dispatcher Visit(Statement stat, object arg) with all arguments
            non-null, unless specified otherwise in the documentation for Visit*.</li>
            </ol>
            
            <p>
            By default, each Visit* method calls the abstract method <c>DefaultVisit</c>.</p>

            Description:
            <br/>
            tests the code at the end of the filter section of a filter handler. If code is 0, handler
            does not apply, and the next handler should be tried. If 1, hander applies and the next instruction
            is executed.
            
            In our encoding, if the instruction falls through, it must push the implicit exception being 
            handled onto the stack, since the next instruction is a catch of the actual handler.

            The main analysis class. Entry point to analyze a method, an assembly or 
            a compilation unit.
            At construction time, you can define if the analysis is interprocedural or only
            intraprocedural. If you choose interprocedural, you can decide for a fixpoint 
            based approach, using a backward traversal over a partial call graph, or an inlining
            simulation (when you can decide the maximum call stack depth).
            The analysis has 2 modes of operation. StandAlone or assuming that is using inside CCI or Boogie.
            The main difference is that in the standalone it tries to analyze all methods it finds in the assembly
            and in the other case it only analyzes methods annotated as [pure] or [confined]. 
            The purpose of the StandAlone mode is the INFERENCE, and of the other mode is VERIFICATION.

            A points-to Graph. Is the structure that represents the points-to information for a program point.
            The model supports Reference types (object subclasses) and struct types. 
            Every program variable has a related node that represents its address. 
            An address node can point to one of several locations (the object/s in the heap). 
            We say that the value/s of an Address are the heap locations that the variable (or address)
            can point to.
            That means, given a = Addr(v), *a represent the actual object abstraction in the heap.
            For struct types Addr(v) directly contains the struct element
            For fields the reasoning is the same. A heap location represent an object (or several) that
            can have several attributes (fields). If the field type is a reference type, it will have
            an address, and the address will point to the heap location representing the field dereference.
            Example: <c>v.f = *((*Addr(v)).f)</c> for v and v.f being reference types. 
            For struct type the reasoning is similar as the addr/value mentioned before. 
            A pointsToGraph G = &lt; I &#44; O &#44; LV &#44; E &gt;
            I = set of inside edges: references generated by the method under analysis
            O = set of outside edges: read refences to elements not known if that program points to
            LV = a mapping from variables to the heap locations it may point to (in particular 
            it is a one to one mapping between variables and their addresses or associated structs)
            
            There are different kind of nodes. 
            AddrNodes: An address of a variable or field
            LAddrNode: An address node created to reflex a loaded (and unknown) address 
            LNode: A node that represent a loaded (and unknown) object. There are subclasses
            to represent if the unknown is a value (content of an address) like LValueNode 
            (and PLNode for parameters values) or a field value (content of a field dereference 
            address) like LFNode
            PNode: A node that represent the address of a parameter. There subclasses to represent 
            the parameter passing style (PByValue, PByRef, POut)
            InsideNode: A newly created object 
            StructNode: A node that represent a struct value type

             <p>The <c>HashSet</c> class overrides the methods
             <see cref="M:System.Compiler.HashSet.GetHashCode">GetHashCode</see> and <see cref="M:System.Object.Equals(System.Object)">Equals</see>
             (inherited from <see cref="T:System.Object">Object</see>) in order to provide
             structural equality:
             two sets are equal iff they contain the same elements (where the semantics of "same"
             is defined by the <c>Equals</c> method of those objects).  You can put HashSets into
             HashSets; however, to avoid infinite loops, you should never insert a <c>HashSet</c>
             into itself.
             The hashcode of a <c>HashSet</c> is defined as the "xor" of the hashcodes of the set
             elements. 
             </p>
             
             <p>
             The <c>GetHashCode</c> function of a <c>HashSet</c> executes in <c>O(1)</c> time:
             the hashcode is dynamically updated after each operation that modifies the set.
             If the hashcode functions used for all the other involved objects is good and
             is computed in <c>O(1)</c> time, one element addition and removal execute in
             <c>O(1)</c> time; <c>Equals</c> works in time linear to the number of elements of
             <c>this</c> set.

               ValueOf(s) to assignment lattice elements as well.

               Field(Value(s))
               
            In addition, we keep a single set (not program point specific) of

             Definite assignment and usage analysis.
             
             Definite assignment is about locations, not values. Thus, we use egraph as follows:
             
             Variables represent locations, thus the symbolic values in the egraph represent location addresses.
             
             We track the status of these locations (assigned, referenced)
             
             To track pointers to locations, we also keep track of terms of the form Value(loc), representing
             the value stored in the location loc.
             
             Thus, an assignment x = y is represented as Value(sym(x)) := Value(sym(y))
             
             
             DELAYED REFERENCES
            
             In order to allow static checking of initialization of circular structures, we introduce the
             notion of a delayed reference. A delayed reference D(T) is a pointer whose type invariants may
             not be valid (and thus observed) until time T. The CLR already has such a notion in the fact that
             "this" is delayed in constructors until the base call.
             We add to this "universally quantified" delays for "This" and other parameters. We track that
             no reads are performed on universally delayed references and that they are stored only in other
             universally delayed references.
             
             Reference types T<amp/> that may point to fields of delayed objects are treated specially. Intuitively,
             these references would have to have the same delay as the pointed to object field.
             Within a method, that is the case. However, the common cases of ref and out parameters that create
             such pointers in regular C#/Spec# code can be handled slightly better.
             Essentially, a delayed reference or a pointer to a field of a delayed reference should never be passed as
             a ref parameter, since it cannot be read prior to initialization.
             On the other hand, passing such pointers as Out parameters seems valid and desirable and in fact does
             not require the parameter to be marked [Delayed], since the out aspect already guarantees initialization
             prior to use. This assumes that the type of the out parameter captures all the invariants that the 
             field should ultimately possess.

             There are two cases:

                 base .ctor call
              2) if the constructor is delayed (guaranteeing that during the constructor execution, no fields of this are ever consulted), then
                 the fields must be initialized by the end of the constructor.

            This is done by keeping track of the number of possible delay matches. 
            if actual/formal is universal/universal, then this number (possibleDelayMatch) is not changed, we allow it only when
                 the number is not zero (the only way it can be zero at this point (delayinstance is true) is because
                 an existential/universal delay match happened.
            if actual/formal is existential/universal, then match happens only when the number is 1
                 number is changed to zero to disallow future existential/universal match
            Delay match error will reported as delay not compatible with the witness. If the witness does not have an appropriate delay
            we do not report an error, which will be safe (see comments below).

            Transforms the nested CCI representation into a flat one.
            
            More precisely it does 3 things
            - It turns nested block structures into a 2 level structure, the method body is a block consisting of blocks. These
              2nd level blocks only contain statements, not nested blocks. All branch targets are to a block in the 2nd level.
              
            - All statements are simplified to three address codes, by splitting complicated expressions so that they push their
              result onto the stack, whereas the continuation pops it off the stack.
              
            - Produces only CfgBlocks
            
            In order to correctly deal with nested dup expressions which appear when the input is not read in
            from an external DLL, but is the output of the compiler, we need to use an explicit stack model.
            Consider the following problem:
            
               Construct(Delegate, [ local0, BinaryExpr(ldvirtfn, dup, Test.M) ]
               
            The dup instruction acts on the local0, which is the first argument to the constructor. Previously,
            we would try to use this local0 directly, without stacking it. Now we have to stack everything.
            
            Stacking everything has the undesirable side effect that data flow analyses that do branch refinement have
            a hard time updating information about tests, since the tests always involve stack variables.

            2. From within a BlockExpression
            3. From the top-level method body block
            
            Because of 2 and 3, we may have a pending list of statements in new_stats that belong
            to the previous block. Thus we first need to end that block, then start the new one.
            
            Furthermore, since the old block could be a branch target, we also must update the 
            orig2newBlock map once we generated the first block within this flattening.
            
            Every block expansion starts with a call to FlattenBlock
             The FlattenBlock stack activation frame keeps track of the prior current_oldBlock 
             and stores the new current oldBlock.
             At the end of FlattenBlock, the prior_oldBlock is mapped to the same new block
             as the oldBlock on which FlattenBlock was called.
             
             POST: this.current_oldBlock == null.

            	/// Control Flow Graph (CFG) for a method.  The CFG is an extra layer on top of
            the CCI representation; all the CFG related information (flow edges) is maintained into
            the CFG object.  Both the normal and the exceptional flows are modeled by the CFG.
            
            <p>THE UNDERLYING CCI REPRESENTATION IS MUTATED *A LOT* BY THE "FINALLY" BLOCK DUPLICATION
            AND THE STACK REMOVAL TRANSFORMATION.  YOU SHOULD MANUALLY CLONE IT BEFORE CONSTRUCTING
            THE CFG IF YOU NEED IT; E.G, IF YOU NEED TO WRITE THE CODE BACK TO DISK.  CFG IS USED FOR
            PROGRAM ANALYSIS ONLY, NOT FOR CODE GENERATION.</p>
            
            <p>A Control Flow Graph is basically an oriented graph whose nodes are the
            basic blocks from the method body; the edges reflect the normal and the exceptional flow
            of control (the exceptional flow is the flow that occurs when an exception is raised).
            In addition to the basic blocks of the original method, three more blocks are added:</p>
            
            <ul>
            <li>a special <c>CFG.NormalExitBlock</c> that is a successor for all the basic block
            terminated in a return instruction; it is a merge point for all the
            paths on the normal (intra-procedural) control flow.</li>
            <li>a special <c>CFG.ExcpExitBlock</c> that is the default handler for all the uncaught
            exceptions; it is a merge point for all the paths on the intra-procedural execution
            paths that may terminate with an uncaught exception.</li>
            <li>a special <c>CFG.ExitBlock</c> that is the only successor of the aforementioned
            normal and the exception exit.  Its only normal flow predecessor is the special block
            for the normal exit and its only exceptional flow predecessor is the special block
            for the exceptional exit. </li>
            </ul>
            
            <p>
            If you are given a block and want to know if it's the [normal/excp] exit of its
            method, all you have to do is use the appropriate "is" test
            (e.g. "block is CFG.NormalExitBlock"). If you have the CFG, and want to know its
            [normal/excp] exit, you just have to query the appropriate method.</p>
            
            <p>
            NOTE:
            If an analysis is interested in the result for the normal flow, then it can retrieve
            the result of the dataflow equations for the normal exit point. Similarly, if an analysis
            is interested in the result for the exceptional flow, then it can retrieve the result
            of the dataflow equations for the exceptional exit point.  Finally, if the distinction between
            normal/exceptional flow is not important, the "unified" exit point can be used instead.</p>

            When we duplicate a finally body and graft it into the normal path,
            the jump that goes to this new code must remain a 'leave' rather
            than a 'branch', because we must retain the semantics that 'leave'
            clears the evaluation stack before jumping. However, to correctly
            do recursive copies (i.e. try/finally inside a finally), we need
            to remember that these leaves are not actual leaves. To mark them,
            we derive a new class from Branch and use an 'is' test to look for 
            this class.
