Modular heap analysis techniques analyze a program by computing summaries for every procedure in the program that describes its effects on an input heap, using pre-computed summaries for the called procedures. In A Framework For Efficient Modular Heap Analysis, the focus is on a family of modular heap analyses that summarize a procedure's heap effects using a context-independent, shape-graph-like summary that is agnostic to the aliasing in the input heap. These analyses are very efficient but their complexity and the absence of a theoretical formalization and correctness proofs makes it hard...
