[LLVMdev] dependent passes

[Ryan M. Lefever]

I am trying to create two passes X and Y, in which pass X depends on 
pass Y.  After attempting this several times it appears that pass Y must 
be in the llvm namespace.  Whenever it was not in the llvm namespace, 
"opt -load" would complain about undefined symbols when I called 
getAnalysis<>(). Am I correct that the pass that is depended on must be 
in the llvm namespace?  If so, that was not clear in the documentation 
regarding writing an LLVM pass.

Thanks,
Ryan
