Excellent job. Thanks! Only two things before you commit:
1. Make sure that you don't have long lines wrapping around 80
columns.
2. Please modify the documentation in doc/tree-ssa.texi to describe
V_MUST_DEF and V_MAY_DEF.
After you make those changes, the patch can go in.
Now that we have the infrastructure for must-defs, you can start
thinking about things we could do with them in the existing optimizers.
Did you get a chance of running this through POOMA and DLV?
Thanks. Diego.
