Thanks Bingfeng.

We are now facing the following problem: 
We are trying to get the .dfa output file, showing details about the
automaton constructed. However we are unable to do so.

We tried
(a.)uncommenting - (automata_option "v") - in ia64.md file
(b.)adding v_flag = 1 in gen_automata_option() function of genautomata.c
file 
and running: make insn-automata.c
None of these gave a .dfa output file.
 
Target language for which optimization is being done: C
Target machine architecture: i686
GCC version: 4.4.1

Kindly help us with our issue.

Thanking All
-Dhiraj
