------- Comment #3 from asl at math dot spbu dot ru  2007-10-04 05:15 -------
The testcase is slightly uninformative.

Note, that %esp is aligned here and %ebp is potentially not (thus locals are
accessed via %esp).

What if:

1. We have dinamic size alloca() call
2. We have incoming arguments. How are they referenced? Via %ebp?
