tools: bpf_jit_disasm: Add option to dump JIT image to a file.
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. This file can then be disassembled off line. 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 <david.daney@cavium.com> Acked-by:
