Found by "disordered --shuffle-dirents=yes". Sorting os.walk() in scripts/subfolder_list.py removes the randomness in the following files: build/zephyr/misc/generated/syscalls_subdirs.txt build/zephyr/CMakeFiles/syscall_list_h_target.dir/ or build.ninja Sorting os.walk() in scripts/parse_syscalls.py removes the randomness in: build/zephyr/misc/generated/syscalls.json build/zephyr/include/generated/syscall_dispatch.c build/zephyr/include/generated/syscall_list.h Note my (limited so far) testing did *not* observe any randomness in any object file that this would address; the main purpose here is to remove a very large amount of noise in diffoscope.
