When debugging the JIT on an embedded platform or cross build environment, libbfd may not be available, making it impossible to run bpf_jit_disasm natively.Add an option to emit a binary image of the JIT code to a file.

Typical usage in this case might be (pasting mips64 dmesg output to cat command): $ cat > jit.raw $ bpf_jit_disasm -f jit.raw -O jit.bin $ mips64-linux-gnu-objdump -D -b binary -m mips:isa64r2 -EB jit.bin Signed-off-by: David Daney <[email protected]>
Seems good, we could at some point also add an -I jit.bin option if needed for offline analysis/comparison instead of using -f plain text. Thanks! Acked-by: Daniel Borkmann <[email protected]>
