Techniques for Improving Grammar Flow Analysis
نویسندگان
چکیده
Grammar Flow Analysis (GFA) is a computation framework that can be applied to a large number of problems expressed on context-free grammars. In this framework, as was done on programs with Data Flow Analysis, those problems are split into a general resolution procedure and a set of speciic propagation functions. This paper presents a number of improvement techniques that act on the resolution procedure, and hence apply to every GFA problem: grammar partitioning, non-terminals static ordering, weak stability and semantic stability. Practical experiments using circularity tests for attribute grammars will show the beneet of these improvements. This paper is a shortened version of JoP].

This paper specifies the theoretical basis for the implementation of different generators of the OPTRAN system. Grammar Flow analysis uses the techniques of data flow analysis at the meta level of compiler construction. The analogue of the states in data flow analysis are the syntax trees together with some information that is associated with trees by propagation functions. One example is the a...
متن کاملBehavioral Analysis of Traffic Flow for an Effective Network Traffic Identification
Fast and accurate network traffic identification is becoming essential for network management, high quality of service control and early detection of network traffic abnormalities. Techniques based on statistical features of packet flows have recently become popular for network classification due to the limitations of traditional port and payload based methods. In this paper, we propose a metho...
