I've been puzzling over this for a day:
Unable to schedule 'Unnamed pass: implement Pass::getPassName()'
required by '<some pass>'
Unable to schedule pass
UNREACHABLE executed at llvm/lib/VMCore/PassManager.cpp:1213!
First, why can't getPassName find the name? I have provided one in the
usual way. Second, why is it unable to schedule the pass?
-debug-pass=Details doesn't provide much help.
This analysis pass is somewhat different in that it has a class
hierarchy like this:
MyPass
|
V
MyPassBase<T>
|
V
MachineFunctionPass
I pass the static ID down through MyPassBase to MachineFunctionPass in
the constructor.
Is there any reason why this inheritance would cause a problem? The
problem occurred when I factored most of MyPass out into MyPassBase for
reuse.
Thanks!

You would need to initialize each subclass of MyPassBase separately and each needs its own ID. -Andy> -debug-pass=Details doesn't provide much help. > > This analysis pass is somewhat different in that it has a class > hierarchy like this: > > MyPass > | > V > MyPassBase<T> > | > V > MachineFunctionPass > > I pass the static ID down through MyPassBase to MachineFunctionPass in > the constructor. > > Is there any reason why this inheritance would cause a problem?

I was passing the ID *value* to the superclass instead of a reference. Confusing error message. :) -David
