Method and system for mapping intermediate representation objects for facilitating incremental analysis

An intermediate representation mapping system (IRMS), comprising:

• a memory storing instructions;
• one or more communication interfaces;
• and
• one or more hardware processors coupled to the memory via the one or more communication interfaces, wherein the one or more hardware processors are configured by the instructions to:
• receive a current version and a previous version of a computer program, and an intermediate representation (IR) associated with each of the current version and the previous version of the computer program, wherein the IR associated with each of the current version and the previous version comprises one or more IR objects loaded in the memory of the IRMS;
• extract one or more attributes associated with each IR object of the one or more IR objects present in the previous version of the computer program, the one or more attributes comprising a line number, an object type, an identification number (ID), and a name of each IR object;
• create and store in a database integrated within the IRMS, a data structure for storing the one or more IR objects present in the previous version of the computer program, wherein each IR object is stored in the data structure based on the one or more attributes extracted for a respective IR object;
• compare the current version and the previous version of the computer program using a data comparison tool to determine one or more lines that are unchanged between the current version and the previous version of the computer program;
• create and store in the database, a line number map based on the one or more unchanged lines, the line number map comprising a line number-based mapping between each unchanged line in the current version and the respective unchanged line in the previous version of the computer program;
• create and store in the database, an ID-based IR mapping between an ID of each unchanged IR object of one or more unchanged IR objects present in each unchanged line in the current version and an ID of each IR object of the one or more IR objects present in the previous version stored in the data structure using the created line number map;
• retrieve the ID of each IR object of the one or more IR objects present in the previous version from the database using the created ID-based IR mapping;
• and
• perform an analysis of the current version incrementally and create an analysis information of the current version, by reusing a previous analysis information of the one or more unchanged IR objects stored corresponding to the retrieved ID, the previous analysis information being retrieved from the database using the retrieved ID as a key for any unchanged IR object in the current version.

One or more non-transitory computer-readable storage mediums comprising one or more instructions which when executed by one or more hardware processors cause:

• receiving, by an intermediate representation mapping system (IRMS), a current version and a previous version of a computer program, and an intermediate representation (IR) associated with each of the current version and the previous version of the computer program, wherein the IR associated with each of the current version and the previous version comprises one or more IR objects in a memory of the IRMS;
• extracting, by the IRMS, one or more attributes associated with each IR object of the one or more IR objects present in the previous version of the computer program, the one or more attributes comprising a line number, an object type, an identification number (ID), and a name of each IR object;
• creating and storing in a database integrated within the IRMS, by the IRMS, a data structure for storing the one or more IR objects present in the previous version of the computer program, wherein each IR object is stored in the data structure based on the one or more attributes extracted for a respective IR object;
• comparing, by the IRMS, the current version and the previous version of the computer program using a data comparison tool to determine one or more lines that are unchanged between the current version and the previous version of the computer program;
• creating and storing in the database, by the IRMS, a line number map based on the one or more unchanged lines, the line number map comprising a line number-based mapping between each unchanged line in the current version and a respective unchanged line in the previous version of the computer program;
• and
• creating and storing in the database, by the IRMS, an ID-based IR mapping between an ID of each unchanged IR object of one or more unchanged IR objects present in each unchanged line in the current version and an ID of each IR object of the one or more IR objects present in the previous version stored in the data structure using the created line number map;
• retrieving the ID of each IR object of the one or more IR objects present in the previous version from the database using the created ID-based IR mapping;
• and
• performing an analysis of the current version incrementally and creating an analysis information of the current version, by reusing a previous analysis information of the one or more unchanged IR objects stored corresponding to the retrieved ID, the previous analysis information being retrieved from the database using the retrieved ID as a key for any unchanged IR object in the current version.
