....on which the execution of the vertices depend [15] Since both control and data dependencies are represented by the PDG, it requires the construction of a CFG and some extensive data ow analysis. PDGs are typically used as a form of intermediate program representation in optimising compilers [7, 32] or in designing program slicers [15] The PDG also introduces several disadvantages, such as the calculation of information that may never be used [29] However, combining the PDG and AST allows for the implementation of meaning preserving transformations [19] Griswold s tool for restructuring ....

....Qadah et al. s [20] empirical results show that the performance of algorithms such as this one are typically sub linear in the number of edges because usually only a subset of the graph is reached, and so only some of the edges are traversed. As is commonly known in data flow analysis (eg [17]) the practical performance of worklist style algorithms depends heavily on the worklist management strategy. We have developed a best first worklist management strategy for algorithm A, although our prototype implementation uses a simple breadth first approach [21] 3 Program Analysis via ....

....program, we d like to do constant propagation rst (to propagate y = false) followed by unreachable code elimination. In general for a program p, B A) p) 6= A B) p) which creates the so called phase ordering problem. A common solution is to iterate the passes until a xpoint is reached (e.g. Muc00] We ll call this approach iterating improvement passes. if false then return x y false if y then return 2 Fig. 1: Two programs to illustrate a phase ordering problem. 1.2 Combining improvements Surprisingly, iterating improvement passes is not always the optimal solution.

....improvement we turn to the problem of removing redundant computations. This is an old and well studied improvement, known in various incarnations as common subexpression elimination [CS70] value numbering [BCS97] lazy code motion [KRS94] and partial redundancy elimination [KCL 99] see e.g. Muc00] for a survey) The inductive approach is straightforward: given some straight line code such as w (b; c) x (a; w) y (b; c) z (a; y) one wishes to eliminate redundant computations in this example, y and z are redundant since y = w and z = x. The classic inductive approach to ....

....dead code, and it detects the use of registers that were not initialized in the analyzed code. Data flow analysis is also helpful when trying to attain optimal scheduling. Height reduction (the process of reducing the control dependence, for example as in ref. 4] and strength reduction (ref. [3] p.435) are easier for assembly programmers to handle when all the dependency chain is analyzed automatically. For software pipelined loops, automatic tracking of the rotating registers used in the loop helps assembly programmers to write modulo scheduled loops. This can also greatly simplify ....
