Creating a tree node from gimple statement.

[Swaroop Joshi <swaroop@xxxxxxxxxxxxxx>]

Hi,

I am using gcc-4.5.0.
Given a gimple statement: a = b + c;
I want a tree node for the rhs (b+c).
Using gimple_assign_rhs1(stmt), etc., I can get (b), (c) as separate 
tree nodes.
Can I make a tree node from these ?

I want to do the same for some other type of statements as well.
For ex., conditional statement: if (x < y) => I want (x < y). Right now 
I am able to get (x) and (y).

Thanks,
Swaroop.
