From 79617801ea0c0e6664cb497d4c1892c2ff407364 Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Thu, 21 Mar 2013 22:22:03 +0100 Subject: filter: bpf_jit_comp: refactor and unify BPF JIT image dump output 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.
