[PATCH bpf v2 5/6] tools: bpftool: resolve calls without using imm field

2018-05-18 Thread Sandipan Das
Currently, we resolve the callee's address for a JITed function call by using the imm field of the call instruction as an offset from __bpf_call_base. If bpf_jit_kallsyms is enabled, we further use this address to get the callee's kernel symbol's name. For some architectures, such as powerpc64, th
