    filter: bpf_jit_comp: refactor and unify BPF JIT image dump output · 79617801
    Daniel Borkmann authored
    If bpf_jit_enable > 1, then we dump the emitted JIT compiled image
    after creation. Currently, only SPARC and PowerPC has similar output
    as in the reference implementation on x86_64. Make a small helper
    function in order to reduce duplicated code and make the dump output
    uniform across architectures x86_64, SPARC, PPC, ARM (e.g. on ARM
    flen, pass and proglen are currently not shown, but would be
    interesting to know as well), also for future BPF JIT implementations
    on other archs.
