Hi,
I found the -postdomfrontier pass in llvm.org/docs/Passes.html, but 'opt' does not accept it. I could not find the relevant codes in PostDominance.cpp in SVN trunk, but I found some relevant codes here http://opensource.apple.com/source/clang/clang-137/src/lib/Analysis/PostDominators.cpp.
I am wondering why this pass is removed and what should I do if I want the post dominance frontier information?
there was some discussion of this on the mailing list already, so I suggest you search the archives.
Ciao, Duncan.
