I am debugging the cc1's loop optimization pass with GDB , and want
to construct some rtx listes based on the loop opimization algorithm
because I want to track most paths in it to understand cc1 better.
It is not easy , since some previous optimizating pass such as
jump-opt and cse-opt have changed the original rtxs . Someone can give
some method , to easily construct a input, or some sources to cover this?
