about df_analyse()

[kripashankar]

Hi
How can i get the def-use and use-def chains using
df_analyse() function . I tried this but didnt worked.

      struct df *df;

      df = df_init ();

      df_analyse (df, 0, DF_ALL);

      df_dump (df, DF_ALL, stderr);

      df_finish (df);

I need to determine the definition and use of each
register (live range of each register) used in a
program..

I appreciate any kind of help or suggestions.
