[phc-general] PHI nodes in CFG dump

[Jimmy Cleary]

Hi Mario,

If I recall correctly, CFGs dumped with --cfg-dump which are in SSA
form should have phi nodes written at the top of basic blocks where
branches join.  They look like, for example, "x__v17 = phi(4,7)",
which means x version 17 is assigned to the result of the phi function
of x version 4 and x version 7.

Keep in mind that this is only in the dataflow branch of phc, not trunk.

Regards,
Jimmy
