llvm dev - Aug 2009 - [LLVMdev] Basic question concerning phi nodes and SSA variable labelling.

I have a basic question concerning how LLVM assigns labels to the LHS of an SSA
assignment. My impression from the interface is you can pick a string which
becomes the label for the result. However if you multiple labels which share the
same name in a function a number gets added to the end of the label (is this
correct?).

In cases where you need to know what these resulting labels are is it best to do
you own enumeration?

Thanks in advance,

Carter.

Yes, exactly.

It's usually best not to use the names for anything within a pass;
they're primarily intended to be a debugging aid.
