    perf tools: Add missing object file to the python binding linkage list · 46cb25b1
    Arnaldo Carvalho de Melo authored
    In ac12f676 ("perf tools: Implement branch_type event parameter") we
    started using the parse_branch_str() function from one of the files used
    in the python binding, which caused this entry in 'perf test' to fail:
    
      # perf test -v python
      16: Try 'import perf' in python, checking link problems      :
      --- start ---
      test child forked, pid 16667
      Traceback (most recent call last):
        File "<stdin>", line 1, in <module>
      ImportError: /tmp/build/perf/python/perf.so: undefined symbol:
      parse_branch_str
      test child finished with -1
      ---- end ----
      Try 'import perf' in python, checking link problems: FAILED!
      #
    
    I must've commited some mistake when running 'perf test' to send the
    pull request for the perf-core-for-mingo-20161024 tag, to have let this
    regression to pass, sigh.
    
    Just add tools/perf/util/parse-branch-options.c and switch from using
    ui__warning(), that is not available in the python binding, use
    pr_warning() instead, which is good enough for this case.
    
    Now:
    
      # perf test python
      16: Try 'import perf' in python, checking link problems      : Ok
