1.
Yes, it's true. Only dominators are computed corectly. Post dominators not.
For more information, and a fix contact me.
Anyway this information is not currently used by GCC so probably
none of you will contact me.

The corectness of my fix is based on the fact that the last basic block is
the
only one that has as successor the EXIT block. Anybody can tell me
if this is correct?
thanx
