No, it is not.  Only if you are doing -fpoints-to=andersen.  The
compute_may_alias pass will build flow-sensitive points-to information
using the SSA form.
So the PROP_pta here is wrong?:


It's not required, it's optional, so yes.
:)

I'll have patches to make points-to work on the SSA form in a week or so. (I just got back from an 11 day vacation).
