Hi, I wrote yet another [1,2] Python binding for LLVM! I'm doing this because llvmlite has some serious limitations: 1) it cannot parse an existing IR, only create new modules [3], 2) it keeps its own representation of the IR (which is less memory efficient than the LLVM one), and 3) each llvmlite version supports a single LLVM version. Considering that my need is to load modules of hundreds

There is llvmlite http://llvmlite.readthedocs.io/en/latest/ , but it doesn't seem to support reading individual instructions, based on these docs. I was thinking to make a simple code analysis tool to, for example, find all system calls that have unchecked return codes, but I can't find a binding for any scripting language. And I am averse to writing this in C++. Thanks, Yuri

As much as I'm not a fan of most XML things, this application of XPath is *inspired*. This would be a great testing/query tool for tests. It would also be a great way to prototype passes. Looking forward to seeing something like this in llvm/tools/ ! Cheers > On 1 Nov 2017, at 04:00, Sean Silva via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > This is so cool! I once

Hi, sometimes when dealing with LLVM IR getting to a desired point of the code is a bit cumbersome, in particular if you're instrumenting existing code. A lot of nested loops and if checks. Maybe all of this could be avoided by employing a query language. Since an LLVM module can be seen as a sort of tree with attributes, I think that reusing an existing query language for XML would be

...c RegisterStandardPasses RegisterMyPass(PassManagerBuilder::EP_ModuleOptimizerEarly, registerCPI); static RegisterStandardPasses RegisterMyPass0(PassManagerBuilder::EP_EnabledOnOptLevel0, registerCPI); And compiled with the following command: comp_3: clang -Xclang -load -Xclang ${LLVM_LIB}/LLVMCPI.so -O0 -c test.c clang -Xclang -load -Xclang ${LLVM_LIB}/LLVMCPI.so -O0 -c fun_lib.c cc *.o ${CPI_LIB} I get the following errors: clang -Xclang -load -Xclang /home/zhangjun/tools/llvm/llvm-build/lib/LLVMCPI.so -O0 -c test.c Pass 'Unnamed pass: implement Pass::getPassName()' is not init...

Hi, I am currently trying to convert C to LLVM IR in python. Till now, I have achieved the task by calling clang in python, but I would like to find something that can allow me to take a file in python and turn it to LLVM IR. I looked at some tools online, such as pycparser and llvmcpy, but it seems like the tool ends at generating the AST but not the IR. Can anyone suggest other tools that I can
