Description

Providing callstacks on each syscall is something on the original feature list that we thought might be useful but was never high enough priority to add.

Contributor guide

Research direction
Examine the drstrace source to understand how syscalls are currently captured (likely using DynamoRIO's system call instrumentation). Look for existing stack walking utilities in DynamoRIO (e.g., drsyms or drwrap) and determine how to integrate callstack retrieval into the syscall record function.
