The Limits of Alias Analysis for Scalar Optimizationscalar optimizations, including an analysis that assumes no aliases, to establish a very loose upper bound on optimization opportunities. We then measure optimization opportunities on thirty-six C programs. In practice, the optimizations are rarely inhibited due to the precision of the alias analyses作者: 喧鬧 時間: 2025-3-22 08:33
Pruning Interference and Ready Dependence for Slicing Concurrent Java Programs reducing the number of . edges considered while slicing concurrent Java programs. The key idea is to statically detect situations where run-time heap objects are reachable from a single thread and use it to prune spurious interference dependence edges. We also show how this analysis can be extended作者: insidious 時間: 2025-3-22 10:43
Data Dependence Profiling for Speculative Optimizationslysis algorithms are developed primarily for Fortran-like subscripted array variables.

A Symbolic Approach to Bernstein Expansion for Program Analysis and Optimizationave still many limitations. In particular, integer multi-variate polynomials arise in many situations while analyzing programs, and analysis systems are unable to handle such expressions. Although some dedicated methods have already been proposed, they only handle some subsets of such expressions.
