Hi, I had cloned zorg from https://llvm.org/svn/llvm-project/zorg/trunk, then I try to start the buildbot master located in buildbot/osuosl/master (the absolute path is /nfs/home/hongbin.zheng/buildbot/zorg/buildbot/osuosl/master) by simply typing "buildbot start" And I get something like this from my twistd.log: --- <exception caught here> --- File "/usr/lib/python2.7/dist-packages/twisted/internet/defer.py", line 545, in _runCallbacks...

...Recently we are thinking to introduce an LLVM bc converter from LLVM 3.9 to LLVM 3.1, such that we can introduce some of the newest LLVM analyses and optimizations to our LLVM 3.1 based project. Have you worked on similar things that converting LLVM bc downward and has anything to share? Thanks Hongbin -------------- next part -------------- An HTML attachment was scrubbed...

...it byte array is introduced to pad the struct. (I saw this happened in clang 3.9.) I want to check if a byte or byte array in an LLVM struct is introduce for explicit padding or not. I don't need to worry about this problem in case the newest clang do not introduce byte array anymore.

Hongbin, Did you tweak sys.path? # Extend paths to allow loading zorg and config modules. import os, sys path = os.path.join(os.environ.get('HOME'), 'zorg', 'buildbot', 'osuosl', 'master') if path not in sys.path: sys.path.append(path) path = os.path.join(os.envi...

...uot;ll" code is simpler. Another approach I am thinking is linking to two different version of LLVM at the same time, and use the old version of IRBuilder to build bitcode from new version of LLVM IR. How do you think about this? At last, we also do not support exception handling:) Thanks.

I don't see any problem mangling it to be honest even though there seems to be only one prototype anyways. We could add restrict in as well.

the packed + aligned attribute will automatically introduce explicit padding byte array: https://godbolt.org/g/TlHX2g Sometimes Clang will decide to automatically pack the struct/class in C++, I don't know the details here, but looks like it is related to inheritance.

...tion is supported, and is mangled according to its prototype as follows: int printf(constant char * restrict fmt, ... ) Note that the ellipsis formal argument (...) is mangled to argument type specifier z It seems printf should be mangled.

Also, the bitcode "downgrade" is done by : // Use the LLVM 3.2 bitcode writer, instead of the top-of-tree version. llvm_3_2::WriteBitcodeToFile(module, OS); Is the corresponding source code also available? if so could you point me to the corresponding file?

...me relative source order. In unswitch2() they have been permuted, and the algorithm cannot deal with this. This requires some kind of value numbering to do efficiently. The GVNSink pass that I really should get around to updating should solve this, eventually!
