Hi, I was trying to build clang (svn head version) using clang-3.1 version. I am building a debug version using LTO/gold plugin. It is crashing with signal 9 when trying to link the bitcode files to build the executable. I am not sure, if this is a bug or just a memory issue. Has anyone done anything similar or noticed similar behavior? Any help would be welcome. Thanks, Swarup.

...rrors. BTW, there is no directory called bfd_plugins inside lib. I think, there is some mistake in the documentation. I just copied the plugin to /lib directory and it works fine. -Swarup. > >Cheers, >-- >Rafael Ávila de Espíndola ************************************* Swarup Kumar Sahoo Thomas M.

Two suggestions: - Use a 64-bit operating system. - You could disable the LTO optimizations by commenting out a few lines in tools/lto/LTOCodeGenerator.cpp to determine if the problem is a pass or with LTO itself.

Hi, I found that LLVM 3.1 says Dominance frontier is deprecated. Can anyone please tell me, if there is any replacement for Dominance frontier & Postdominance frontier in LLVM? What are the options if we need to use them? Thanks, Swarup. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Dear Tarun, Swarup Sahoo and I wrote some LLVM passes for dynamic slicing for LLVM 2.6. I believe we had planned to make the code publicly available as part of the Giri project (http://llvm.org/viewvc/llvm-project/giri/trunk), but due to other commitments, we have not moved the code into that SVN repository yet. Let me c...

Hi, I want to find the dynamic slice of a given code. Is this already implemented in LLVM?. If not which functions are there in the LLVM to do dynamic analysis.

I can look into more details when I get back from vacation. Swarup may also be able to provide information on the giri code. I took a quick look, and the dynamic slicing code doesn't appear to be checked into the giri
