However, their Makefile rules add xstate.c directly to EXTRA_FILES without registering it as a prerequisite. As a result, modifying xstate.c does not trigger a rebuild of the affected test binaries, potentially leaving stale test executables. Use the existing extra-files macro to register xstate.c as both an additional compilation input and a build dependency.
