...ied with llvm-6 and llvm-7. I notice that if I change EP_EarlyAsPossible to anything else it does not crash but I don't see the expected string printed by the runOnSCC. Could you help me to solve this problem? How should I create the 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,...

I'm looking for a "Hello, world" pass example that ideally has all of the following properties: 1) Complete. That is, it should have functional CMakeLists.txt, etc. files. 2) Out-of-source. That is, it should build against a binary LLVM installation. 3) Modern. That is, I don't want to use any deprecated APIs or CMake macros. 4) Clang-compatible.

...river. I tried 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.

Hi I am trying to install llvm and clang on ubuntu 16.04, I tried installing them using apt command but while running the pass it gives me error "error: llvm/pass.h not found *#include"llvm/pass.h"* so i tried installing using the source code and building it my self, *make *fails at 98% with this error *collect2: error: ld returned 1 exit

Hello, I am a computer science student new to LLVM compiler infrastructure. Please guide me where to start from to learn LLVM in the most effective way.

Hi, I have written MyPass.cpp and I use "EP_FullLinkTimeOptimizationLast". I compile it and get libMypass.so. MyPass.so rely on some other code, such as，Init.c and Helper.c. So, I use following commands to get a static library libmypass-rt.a. " $ clang -fsanitize=safe-stack -c -emit-llvm -fpic -Wall -Wextra -O2 -I ../include -o obj/helpers.o helpers.c $ clang -fsanitize=safe-stack
