Hi, I was looking at the LoopInfo Analysis pass as an example, and found it defined the isAnalysis() method to return true. I assumed the method was overriden from some superclass (Pass, probably) and present in all analysis passes. However, a better look turns out that the method isn't really used anywhere. PassInfo does define the same method which is used, but PassInfo is not a supercla...

Yes, that would make sense, except I don't see any pointers being passed. The relevant line in lib/Transforms/Hello.cpp is: static RegisterPass<Hello>

Hi, I'm confused about the is_analysis parameter of the RegisterPass constructor (defined in PassSupport.h). The only explanation I can find is that is_analysis should be set to true if the pass is "an analysis pass, for example dominator tree pass". Can someone please clarify what is meant by "analysis pass"? Also -- and this is more of a C++ question than an

...t you need to know is that these classes are going away, and are being replaced with a new macro INITIALIZE_PASS(). I will be applying this change to LLVM HEAD shortly. You can update you code as follows: static RegisterPass<GVN> X("arg", "My Pass's Name", CFGOnly, IsAnalysis); becomes: INITIALIZE_PASS(GVN, "arg", "My Pass's Name", CFGOnly, IsAnalysis); For the moment, these are equivalent, but as the work progresses on this front, RegisterPass will go away and INITIALIZE_PASS will be changed to expand to the right thing for the new system T...
