Thanks, John. This sounds reasonable that the analysis group just provides an interface to its implementors (pass). Then I have another question, is it allowed to specify multiple pass in the same analysis group in the command line for opt? If yes, which pass will be used for the call of getAnaysis<AnalysisGroup>()? -Thomson On Mon, Jun 25, 2012 at 10:34 PM, John Criswell <criswell at illinois.edu>wrote: > On 6/24/12 10:37 AM, Thomson wrote: > > I found that ProfileInfo is contained in an analysis group, but > ProfileInfo class itself is not derived from any base c...

...has the InComplete Bit on. But when I use 'analyze -tddatastructure file.bc' I got the graph in which all the nodes don't have the bit on. So they are different. Could you tell me why the results from the analyze tool and from the dsg.dump() are different? Besides, each time I call the getAnaysis<TDDataStructure>(), it writes out some bu_funname.dot files to the disk. Why is that?

...analyses (like points-to analysis) in which one analysis tries to get a result and, if it can't get as good a result as it likes, asks the next analysis in the chain (see http://llvm.org/docs/WritingAnLLVMPass.html#AU::addRequired). > If yes, which pass will be used for the call of > getAnaysis<AnalysisGroup>()? I believe the chain is in reverse order. So if you specify opt -pass1 -pass2 -pass3 -transform, and transform queries the analysis group to which pass1, pass2, and pass3 belong, then pass3 is queried first. If pass3 then queries another pass in the analysis group, the...

I found that ProfileInfo is contained in an analysis group, but ProfileInfo class itself is not derived from any base classes of passes, so it appears not to be a pass. Anything I missed here?

Anything I missed here? This is just a guess, but I suspect that the ProfileInfo class defines the interface which all passes in that analysis group are expected to

Dear LLVM, I was wondering if this is the right way to get TopDown DSGraph? TDDataStructures &TD = getAnalysis<TDDataStructures>(); F is some function DSGraph &dsg = TD.getDSGraph(F); I found out the DSGraph I got using this method is actually bottom up DSGraph, can you let me know why? Thanks, xiaodong
