it doesn't make much sense but bcs I have now several jit compilers - why not compare how much size have jitted code for different processors?
I chose 3 ebpf programs
- simple BPF_PROG_TYPE_CGROUP_SKB with only comparison, 8 opcodes
- BPF_PROG_TYPE_RAW_TRACEPOINT with 3 maps, 68 opcodes
- enough complex BPF_PROG_TYPE_RAW_TRACEPOINT with 6 maps, 1824 opcodes
