Class type Cil.cilVisitorSource
A visitor interface for traversing CIL trees. Create instantiations of * this type by specializing the class Cil.nopCilVisitor. Each of the * specialized visiting functions can also call the queueInstr to specify * that some instructions should be inserted before the current instruction * or statement. Use syntax like self#queueInstr to call a method * associated with the current object.
method vvdec : varinfo -> varinfo visitActionInvoked for each variable declaration. The subtrees to be traversed * are those corresponding to the type and attributes of the variable. * Note that variable declarations are all the GVar, GVarDecl, GFun, * all the varinfo in formals of function types, and the formals and * locals for function definitions. This means that the list of formals * in a function definition will be traversed twice, once as part of the * function type and second as part of the formals in a function * definition.
method vvrbl : varinfo -> varinfo visitActionInvoked on each variable use. Here only the SkipChildren and * ChangeTo actions make sense since there are no subtrees. Note that * the type and attributes of the variable are not traversed for a * variable use
method vexpr : exp -> exp visitActionInvoked on each expression occurrence. The subtrees are the * subexpressions, the types (for a Cast or SizeOf expression) or the * variable use.
method vlval : lval -> lval visitActionInvoked on each lvalue occurrence
method voffs : offset -> offset visitActionInvoked on each offset occurrence that is *not* as part * of an initializer list specification, i.e. in an lval or * recursively inside an offset.
method vinitoffs : offset -> offset visitActionInvoked on each offset appearing in the list of a * CompoundInit initializer.
method vinst : instr -> instr list visitActionInvoked on each instruction occurrence. The ChangeTo action can * replace this instruction with a list of instructions
method vstmt : stmt -> stmt visitActionControl-flow statement. The default DoChildren action does not * create a new statement when the components change. Instead it updates * the contents of the original statement. This is done to preserve the * sharing with Goto and Case statements that point to the original * statement. If you use the ChangeTo action then you should take care * of preserving that sharing yourself.
method vblock : block -> block visitActionBlock.
method vfunc : fundec -> fundec visitActionFunction definition. Replaced in place.
method vglob : global -> global list visitActionGlobal (vars, types, etc.)
method vinit : varinfo -> offset -> init -> init visitActionInitializers for static, * const and global variables, * pass the variable where this * occurs, and the offset
method vtype : typ -> typ visitActionUse of some type. Note * that for structure/union * and enumeration types the * definition of the * composite type is not * visited. Use vglob to * visit it.
method vattr : attribute -> attribute list visitActionAttribute. Each attribute can be replaced by a list
method vattrparam : attrparam -> attrparam visitActionAttribute parameters.
method queueInstr : instr list -> unitAdd here instructions while visiting to queue them to precede the * current statement or instruction being processed. Use this method only * when you are visiting an expression that is inside a function body, or * a statement, because otherwise there will no place for the visitor to * place your instructions.
method unqueueInstr : unit -> instr listGets the queue of instructions and resets the queue. This is done * automatically for you when you visit statements.
