Sorry for late reply.

There's lib/test_bpf.c, see Documentation/networking/filter.txt +1349
for some more information. It basically contains various test cases that
have the purpose to test the JIT with corner cases. If you see a useful
test missing, please send a patch for it, so all other JITs can benefit
from this as well. For extracting disassembly from a generated test case,
check out bpf_jit_disasm (Documentation/networking/filter.txt +486).

Thanks,
Daniel
