In this thesis we first investigate the reaching definitions optimization. This compiler optimization collects and stores information about where a variable is defined and how long that definition of the variable stays alive before it is redefined. We compare the old iterative solution to a new algorithm that uses the partialout concept. The partialout solution decreases execution time by eliminating the multiple passes required in the iterative solution. Currently, compilers that find a data dependence between two statements in a loop do not parallelize the loop. Next we investigate automatic parallelism for these loops by breaking the loop into a set of smaller loops, each of which contains no dependencies and thus can be executed in parallel. Finally, we introduce a set of algorithms for optimal processor utilization. The algorithms split the loop into a sequential series of parallel blocks, each block executing in parallel and utilizing the optimal number of processors possible.
