    perf annotate: Add itrace options support · 4bcbe438
    Yang Jihong authored
    The "auxtrace_info" and "auxtrace" functions are not set in "tool" member of
    "annotate". As a result, perf annotate does not support parsing itrace data.
    
    Before:
    
      # perf record -e arm_spe_0/branch_filter=1/ -a sleep 1
      [ perf record: Woken up 9 times to write data ]
      [ perf record: Captured and wrote 20.874 MB perf.data ]
      # perf annotate --stdio
      Error:
      The perf.data data has no samples!
    
    Solution:
    
    1. Add itrace options in help,
    2. Set hook functions of "id_index", "auxtrace_info" and "auxtrace" in perf_tool.
    
    After:
    
      # perf record --all-user -e arm_spe_0/branch_filter=1/ ls
      Couldn't synthesize bpf events.
      perf.data
      [ perf record: Woken up 1 times to write data ]
      [ perf record: Captured and wrote 0.010 MB perf.data ]
      # perf annotate --stdio
