Problem 1
---------

Start with the recog function and trace down the labels and goto statements
   for the following pattern.

   (jump_insn 12 11 13 3 
        (set (pc)
                (if_then_else (le:SI (reg:SI 41)
                        (reg:SI 42))
                        (label_ref 19)
                    (pc)))
          (nil))


Problem 2
---------

Create a pattern from the following path by tracing it from insn-recog.c.

Generate a pattern which satisfy the following path of labels by tracing the 
  the goto statements from insn-recog.c. Can you identify what the output of
  the pattern ?
  
L13 --> L240 --> L14 --> L241 --> L23 --> L243 --> L29 --> L246 --> 
L33 --> L34 --> return 10.
