Hi All, I am an experienced compiler engineer, I want to get involved in LLVM but don't know where I should start with. Can someone give any suggestion for my situation? I hope can do some easy work at beginning, then do some challenge work when I am familiar and comfortable with LLVM. I am interested in optimizations and code generations, but I am open to other areas either. Any suggestion is welcome, thanks in advance.

Hi Baoshan, Firstly, welcome! ;) This is a good place to start: http://llvm.org/OpenProjects.html It might be a bit out-of-date, but you can always ask on the list about a particular project. To get acquainted with the code base, I suggest reading at least: http://llvm.org/docs/GettingStarted.html http://llvm.org/docs/LangRef.html http://llvm.org/docs/ProgrammersManual.html http://llvm.org/docs/CodingStandards.html Happy hacking! cheers, --renato On 31 January 2014 14:15, Baoshan Pang <pangbw at gmail.com> wrote:> Hi All, > > I am an experienced compiler engineer, I want to get involved in LLVM but > don't know where I should start with.

Hi Rento, Thanks for your suggestion, it really helpful, I will go through the links you have given. And if you have any 'dirty' work at hand and want someone to help you to do, please let me know, I would be happy to put my hands on.

File bug reports and then start figuring out what parts of the compiler may need improvement. Running clang with -mllvm -print-after-all is often enlightning. One area in which we really need some work is quantifying how various optimizations affect the performance of multithreaded applications. There was some discussion of this issue here (http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-November/067998.html), as an example, but we really need a lot more effort in this area. -Hal> > Regards, > Baosan > _______________________________________________ > LLVM Developers mailing list > LLVMdev at cs.uiuc.edu http://llvm.cs.uiuc.edu > http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev >-- Hal Finkel Assistant Computational Scientist Leadership Computing Facility Argonne National Laboratory
