The abstract domain contains Separation Logic formulas that (1) combine a per-object separating conjunction with a per-field separating conjunction and (2) constrain a set of variables interpreted as sets of objects. The definition of the abstract domain operators is based on a notion of homomorphism between formulas, viewed as graphs, used recently to define optimal decision procedures for fragments of the Separation Logic. Based on a Frame Rule that supports the two versions of the separating conjunction, the analysis is able to reason in a modular manner about non-overlaid data structures and then, compose information only at a few program points, e.g., procedure returns. We have implemented this analysis in a prototype tool and applied it on several interesting case studies that manipulate overlaid and nested linked lists.\r\n","lang":"eng"}],"publisher":"Springer","file_date_updated":"2020-07-14T12:45:37Z","has_accepted_license":"1","oa_version":"Submitted Version","doi":"10.1007/978-3-642-38856-9_10","alternative_title":["LNCS"],"month":"01","date_published":"2013-01-01T00:00:00Z","quality_controlled":"1","department":[{"_id":"ToHe"}],"intvolume":"      7935","conference":{"start_date":"2013-06-20","name":"SAS: Static Analysis Symposium","location":"Seattle, WA, United States","end_date":"2013-06-22"},"scopus_import":1,"date_updated":"2021-01-12T06:56:36Z","file":[{"creator":"system","file_name":"IST-2014-196-v1+1_sas13.pdf","file_id":"4824","access_level":"open_access","checksum":"907edd33a5892e3af093365f1fd57ed7","content_type":"application/pdf","relation":"main_file","file_size":299004,"date_created":"2018-12-12T10:10:36Z","date_updated":"2020-07-14T12:45:37Z"}],"status":"public","citation":{"short":"C.
