Hi list, I have several questions about LLVM pass. 1) Is building a custom LLVM pass out-of-source not recommended? The official document only contains instructions about in-source build (http://llvm.org/docs/WritingAnLLVMPass.html <http://llvm.org/docs/WritingAnLLVMPass.html>). 2) opt (ver >= 4) with custom pass libraries does not work as before. When I have a simple custom LLVM pass

Hello, I have written a pass that works nicely if I use it with the opt tool, as proposed by the "Writing an LLVM Pass" tutorial. Now I want to execute this pass directly when clang is executed. I use the technique described here: http://homes.cs.washington.edu/~asampson/blog/clangpass.html. The pass is loaded and executed, when I run clang with the right command line. But clang proceeds to crash. It always crashes because of assertions that test types (e.g. the types of arguments of a call). So far i figured out that this is because while the types are the same, their contexts...

...running the pass: clang output.c -o output -Xclang -load -Xclang lib/LLVMMyPass.so -mypass -myarguments However, the pass is not being run as I cannot see output from my pass. What is the standard way to do it? I have also tried approach described here: https://www.cs.cornell.edu/~asampson/blog/clangpass.html . It didn't work.
