Sir, I am interested in adding a new analysis or optimization pass and building the getting started guide as a project for gsoc.

Hi, John Criswell Thank you very much. I am installing LLVM-3.2, but I encounter the next error when carrying out "make": llvm[3]: Compiling ClangASTNodesEmitter.cpp for Release+Asserts build ClangASTNodesEmitter.cpp: In member function ‘std::pair<llvm::Record*, llvm::Record*><unnamed>::Cla...

Sir, I am interested in add a new pass. I have read about analysis, transformation passes. Can you help me with some example ideas?

...c. Okay. Decide which of these two projects you'd like to propose and write up a description of the project. Be sure to include some details. For example, if you're going to improve the documentation, describe the current deficiencies and how you plan to address them.

...el for each pointer variable. I think the data dependence through pointers can be described more accurately in this way. Unfortunately i didn't find any available interface to finish this job, so i guess i have to write it by myself.

I am just not upgrade my LLVM.

...ight? Yes. For working with poolalloc, I would recommend using LLVM 3.2 as we know poolalloc compiles with LLVM 3.2. If there's a release_29 branch for poolalloc, you could use that, but you won't get any bug fixes that we added between poolalloc 2.9 and poolalloc 3.2.

No i have not worked previously on llvm. I have looked through the projects but because of no prior experience i am unable to pick one. I am currently going through the llvm tutorials.

...ks John. Does this solve the problem of analysis availability though? If I still have to run the function analyses manually, I might as well keep rolling with the CallGraphSCCPass. (I probably should have mentioned that this is what I’m using right now.)

Hi Criswell, Thanks for the reply.

Which compiler are you using to compile poolalloc? Looks like it doesn't support C++11 (doesn't recognize nullptr).

John, thanks for you answer! But as far as I know LLVM doesn't provide any interface for finding the pointee of a pointer directly, so i have to process a multi-level pointer i need to write my own function to check pointers level by level, is that right?

...nce-like in manner. When I start teaching students how to use LLVM, I direct them to three difference documents. It might be good to have a "Getting Started with Programming with LLVM" guide to help new students learn how to get started with using the infrastructure.

...e" which represents all unresolved calls (e.g., indirect function calls). Technically, you need to start searching from this node as well as the main() node (as a program can call out to external code which then calls back into the program; think of qsort() as an example).
