Extracting operand name and value from GIMPLE assignment statements

I am writing a GCC plugin in which I need to extract the variable name
and the assigned value from the statements.
I am able to get the three operands from GIMPLE statements like this
tree lhsop = gimple_assign_lhs(stmt);
tree rhsop1 = gimple_assign_rhs1(stmt);
tree rhsop2 = gimple_assign_rhs2(stmt);
I want to get the exact variable name from lhsop and value from rhsop1
(for statements such as
"var = value;", rhsop2 is 0 for such statements.). Some pointers to
example code or documentation would be great. I can't find anything
Thanks a lot !
