similar to: [LLVMdev] road blocks in support shared library of llvm

Actually, adding a LLVM_EXPORT macro would be positive for other environments, because you can then build LLVM as a shared library with -fvisibility=hidden and use LLVM_EXPORT to only make public symbols visible. There are several advantages to this, as noted here: http://gcc.gnu.org/wiki/Visibility From: Reid Kleckner Sent: Wednesday, May 08, 2013 6:21 PM To: Peng Cheng Cc: LLVMdev at

According to http://llvm.org/docs/CMake.html, "Shared libraries are not supported on Windows and not recommended in the other OSes". The problem is that static libraries have some limitations, especially when linked into multiple shared libraries, the global data of llvm could have multiple copies leading to undefined behaviors. This has caused much pains during my usage of llvm. My

Does anyone know what is the complexity of the "mem2erg" optimization on llvm ir? Is it linear or quadratic? Regards, -Peng -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20150817/c3b210f1/attachment.html>

Hi Peng, Can you please open a bugzilla and attache the LL file ? Can you please reproduce it on ToT ?

I have a function in llvm ir as follows: def [2 x [3 x double]] @fun() { return [ ... ]; // a [2 x [3 x double]] constant } I would like to JIT this function in C. I first get the void pointer using: void *FPtr = TheExecutionEngine->getPointerToFunction( func ); Then I need to conver this void pointer to the corresponding C function pointer type, and then call the function

Dear list, I have developed a forward-time population genetics simulation environment simuPOP, which is a set of C++ (template) classes/functions wrapped by SWIG as Python libraries. R is used extensively as plotting and statistical analysis engine through RPy package. I use Python to wrap simuPOP since most the following can be easily done using SWIG or Python C API. However, since Python is

Hi All, In my recent work using llvm to build a jit engine for a language, I saw some warnings and bug in the llvm headers. I made the fix locally and it works well. I am wondering how I could submit the fix back to llvm? Thanks, -Peng -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, I'd like to track not just at the function level, but also at the code block level. For example, for a if-else statement, I want to know when the if-branch or else-branch is enter/exit. Is there a clang option similar to -finstrument-functions for code blocks? Alternatively, I could manually insert the code to the IR .ll file. I see the generated .ll use the following function when

Hi, I have an ir at the end of this email. Run it with: llc -mcpu=i386 -march=x86-64 -mattr=-sse2 and get assertion below. Changing cpu does not help. I am using llc from the latest svn repository. Any suggestions to work around this? I need to disable sse2 instructions for x86-64. Thanks, -Peng -----error message------ llc: X86FloatingPoint.cpp:332: unsigned int getFPReg(const

Hi, I know this is a little bit offtopic on this list. But I can't find a more appropriate forum that I can ask. If there is a high quality forum on statistics textbook discussion, please let me know. I am reading Applied Linear Statistical Models. One drawback that I feel about this book is that it discuss many examples, which is to distracting. Numbers are give in those examples. Comments

Hi, I run the following command and try to save the commands that have been run in the script. But it seems that no history is recorded. Is it because that the history is not recorded in Rscript?
