Exceptional Control Flow II
ثبت نشده
چکیده
System Runs Many Processes Concurrently Process: executing program State consists of memory image + register values + program counter Continually switches from one process to another Suspend process when it needs I/O resource or timer event occurs Resume process when I/O available or given scheduling priority Appears to user(s) as if all processes executing simultaneously Even though most systems can execute only one process at a time Except possibly with lower performance than if running alone

Understanding Exceptional Behavior and Exception Flow in Implicit Invocation Systems by Mehdi Bagherzadeh, Hridesh Rajan and Ali Darvish
Exceptions and their implicit control flow complicate modular understanding (reasoning) of both exceptional behavior and exception flow of a system. Such reasoning tasks about exceptions are more complicated in implicit invocation (II) systems, where a subject module can invoke other observer modules without knowing about them and especially behavior and flow of their exceptions. In this work, ...

متن کاملStatic Analysis of Non-interference in Expressive Low-Level Languages
Early work in implicit information flow detection applied only to flat, procedureless languages with structured control-flow (e.g., if statements, while loops). These techniques have yet to be adequately extended and generalized to expressive languages with interprocedural, exceptional and irregular control-flow behavior. We present an implicit information flow analysis suitable for languages w...
متن کاملGingival microleakage in class II composite restorations using different flowable composites as liner: an in vitro evaluation
Introduction: One of the main disadvantages of composites is marginal microleakage using flowable composites as a liner beneath composite restorations has been recommended to reduce microleakage. The aim of this study was to assess the microleakage of class II restorations with different flowable composites liners. Materials & Methods :45 extracted premolars teeth with class II cavity prepar...
متن کاملProvably Correct Control-Flow Graphs from Java Programs with Exceptions
We present an algorithm to extract flow graphs from Java bytecode, including exceptional control flows. We prove its correctness, meaning that the behavior of the extracted control-flow graph is a sound over-approximation of the behavior of the original program. Thus any safety property that holds for the extracted control-flow graph also holds for the original program. This makes control-flow ...
