[LLVMdev] Requiring a pass to run before/after a pass? (Adding PHIs and updating uses)
...AU) {
AU.addRequired(my stuff);

I'm trying to transform a CFG where A flows into B and C, and I'm making a
copy of A, A_copy, which will also flow into B and C. Right now I'm making a
merge point mergeB where both A and A_copy flow into it, and it then flows
into B. Same for C.

For any values %v deffed in A and A_copy, mergeB has the phi...
