I've been using DSGraph->dump() to get the DSGraph of some functions,
but the report make little sense to me. I'm specially looking for the
"N" flag mentioned by prof. vikram yesterday.
How can I read the results (so that I can manually verify that my
passes are making a good job) or there is some other DSGraph function
better suited for human consumption?

First off, make sure you are sending the graphs through the "dot" utility.
It turns them into a nice format that is much easier to visualize than the
text format...

I'm not sure what your question is, but the N class means "new" or
allocated by a malloc call. There are lots of other flags, which come
from this code snippet in Printer.cpp:
if (N->NodeType & DSNode::ScalarNode) OS << "S";
if (N->NodeType & DSNode::AllocaNode) OS << "A";
if (N->NodeType & DSNode::NewNode ) OS << "N";
if (N->NodeType & DSNode::GlobalNode) OS << "G";
if (N->NodeType & DSNode::Incomplete) OS << "I";
if (N->NodeType & DSNode::Modified ) OS << "M";
if (N->NodeType & DSNode::Read ) OS << "R";
From the flag name you can get a general idea for what the letters
correspond to... let me know if you still have questions...

now....

Is each project group working off the same tree rather than having one tree for
each member? You could actually use RCS to lock out your groupies while editing
code. Of course permissions would have to be adjusted so you can share a tree
among all group members. The paranoid could use access control lists. I'm not
actually in the class so YMMV.
