One possible choice would be llvmcpy -- Python bindings used by the rev.ng (https://rev.ng/) project: https://github.com/revng/llvmcpy Here's an example showing syscalls invocations tracing: https://github.com/revng/revamb/blob/master/docs/PythonExample.rst#tracing-all-the-syscall-invocations Best, Matt

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

Hello folks, I was interested in the support we have for the attribute form DW_FORM_implicit_const (DWARFv5 feature) in clang/LLVM. And I had some doubts wrt this. I noticed that support for this was put in here in 2017: https://rev.ng/gitlab/revng-bar-2019/llvm/commit/d9df13befcbc702e239b650dd1f55778d72b8571 >From what I could make out, the support for generating DW_FORM_implicit_const is there, but I could not make out the DWARF attributes for which this form is being generated currently. Are there any attributes for which this form i...

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
