Hi Mikhail, As Brian noted, stuff like this works better in the new pass manager. Even in the old pass manager I thought it should work though. Did you initialize the pass, via `INITIALIZE_PASS_DEPENDENCY(PostDominatorTreeWrapperPass)`? Did you require it, via ` AU.addRequired<PostDominatorTreeWrapperPass>();`? Btw. May I ask what you are planning to do? Cheers, Johannes On 01/07,

Hi Chandler, This is a high-level review of the new WIP `PassManager` infrastructure. For those that haven't dug into Chandler's commits, here's a very high-level overview (assuming IIUC): - The driver supports simple declarative syntax for specifying passes to run. E.g., `module(a,b,function(c,d),e)` runs module passes `a` and `b`, then function passes `c` and `d` for
