llvm dev - Oct 2002 - [LLVMdev] Alias for reporting LLVM bugs or patches

We have created a new alias -- llvmbugs at cs.uiuc.edu.  Please use this
for reporting bugs or turning in patches for LLVM.  Any such feedback
would be appreciated!

Please continue to use llvmdev to post questions or have discussions
about LLVM.

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";
