Hello, I want to traverse CallGraph code segment: virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<CallGraph>(); } virtual bool runOnModule(Module &F) { CallGraph &g = getAnalysis<CallGraph>(); for ( CallGraph::iterator i = g.begin(); i != g.end(); i++) { errs()<<"-----------------\n";

1. Ok will do. 2. Ok, will do. 3. It's a CallGraphPass. I mentioned this in my first post. 4. Yep, I have the header files included, I'm not sure it would compile otherwise (previously). I would get an error like LoopInfo not declared. I'll try your suggestions, thanks again! On Thu, Nov 10, 2011 at 9:57 AM, John Criswell <criswell at illinois.edu>wrote: > On 11/10/11

LLVMers, I am doing a CallGraphPass but would like to get the LoopInfo of the functions inside this pass, is this possible? Currently I have a function inside the CallGraph struct: void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<LoopInfo>(); AU.addPreserved<LoopInfo>(); } And later inside the pass I am calling: LoopInfo &LI =

John, This did not work. It compiles (isDeclaration was the name of the function) and I passed a reference (&F) (F is a function pointer). I still get the opt load error from the original message (UNREACHABLE exectuted!). Thanks. On Thu, Nov 10, 2011 at 10:00 AM, Ryan Taylor <ryta1203 at gmail.com> wrote: > 1. Ok will do. > 2.

Yes, this demanding comes from our recent research project. If it's avaiable, could you send me the source code of taint-tracking analysis ? I really appreciate your help.

Tobias, I am working on one very well hidden issue with Polly loop structure. Here is a brief description. In polly::createLoop() we create something like this (topology is important): polly.start: ; preds = %polly.split_new_and_old ... <some code> br label %polly.loop_header polly.loop_after: ; preds =

In order to detect whether CallSite is present in innermost loop, do I need to insert logic from LoopInfo pass for collecting loops, within a CallGraphSCC pass?   Is there any other approach for this?   Regards, Pankaj -------------- next part -------------- An HTML attachment was scrubbed...

Okay, its not that simple. Several files in Transforms/Utils depend on things in lib/Analysis. A quick grep shows: BreakCriticalEdges.cpp:#include "llvm/Analysis/Dominators.h" BreakCriticalEdges.cpp:#include "llvm/Analysis/LoopInfo.h" CloneTrace.cpp:#include "llvm/Analysis/Trace.h" CodeExtractor.cpp:#include "llvm/Analysis/Dominators.h"

I think I can squeeze everything into a function pass, but I'd like to run this by you, just in the case I mixed-up something: (Chris, I'd also appreciate you wise thoughts on this.
