System and method for generating a compact unwinding table for reconstructing call stacks to monitor program optimization

A non-transitory computer readable medium having stored thereon instructions for causing a processing circuitry to execute a process, the process comprising:

• extracting a plurality of instruction entries and an offset value for each of the plurality of instruction entries from at least one frame description entry (FDE), wherein each of the at least one FDE contains information for the plurality of instruction entries;
• selecting a subset of the extracted plurality of instruction entries, wherein the subset includes relevant instruction entries for unwinding;
• generating a compact unwinding table based on the subset to include the instruction entries and respective offset values;
• and
• storing the generated compact unwinding table with respect to a source binary file.

A system for generating a compact unwinding table for call stack unwinding, comprising:

• a processing circuitry;
• and
• a memory, the memory containing instructions that, when executed by the processing circuitry, configure the system to:
• extract a plurality of instruction entries and an offset value for each of the plurality of instruction entries from at least one frame description entry (FDE), wherein each of the at least one FDE contains information for the plurality of instruction entries;
• select a subset of the extracted plurality of instruction entries, wherein the subset includes relevant instruction entries for unwinding;
• generate the compact unwinding table based on the subset to include the instruction entries and respective offset values;
• and
• store the generated compact unwinding table with respect to a source binary file.
