Source-based Code Coverage — Clang 9 documentation
Of course that a shared library written in C/C++ would be useful for a lot of Genetic Programming engines that doesn’t uses Python, but since my spare time to work on this is becoming more and more rare I started to rethink the approach and use Python and the LLVM bindings for LLVM and I just discovered that is pretty easy to JIT a restricted set of the Python AST to native code using LLVM... In order to access the clang AST, your python script must be provided with an interface that allows it to use Clang AST library functions. Unfortunately, libclang is a C interface to the Clang front-end. Fortunately, there exist bindings for Python that allow you to interface with the Clang front-end. Link with more information:

I have readed clang’code and some tips from the mailing list,and now I get a way from the ASTUnit::Save to use ASTWriter to write an AST to a file,but still can’t figure out how to use ASTReader. My question is: 1.How can i create an ASTUnit object to use the existing code to manipulate ASTWrite,Or I have to copy these codes to do so…...

llvmpy is a Python wrapper around the llvm C++ library which allows simple access to compiler tools. It can be used for a lot of things, but here are some ideas: dynamically create LLVM IR for linking with LLVM IR produced by CLANG or dragonegg; build machine code dynamically using LLVM execution engine; use together with PLY or other tokenizer and parser to write a complete compiler in Python how to know when an amazon sale ends For the general LLVM release notes, see the LLVM documentation. All LLVM releases may be downloaded from the LLVM releases web site .

The LLVM compiler infrastructure provides a powerful way to optimize your applications regardless of the programming language you use. Learn to instrument code in LLVM, using the clang API to preprocess C/C+ code in this second article of a two-part series.

  • I managed to compile successfully clang for windows with cmake and visual studio 10. I would like to get an XML file as AST representation of the source code.
  • Matching the Clang AST¶ This document explains how to use Clang’s LibASTMatchers to match interesting nodes of the AST and execute code that uses the matched nodes. Combined with LibTooling , LibASTMatchers helps to write code-to-code transformation tools or query tools.
  • In my clang-tool, I want to do some analysis on AST after visit some specific type of Stmt Node. So I need to go to the parent AST node of current stmt.
  • Chapter #3: Code generation to LLVM IR - With the AST ready, we can show off how easy generation of LLVM IR really is. Chapter #4 : Adding JIT and Optimizer Support - Because a lot of people are interested in using LLVM as a JIT, we’ll dive right into it and show you the …
