Simple LLVM Pass Demo

TL;DR

This pass is a tutorial LLVM pass that store every binary operation results into memory and load it back immediately.

Build

mkdir build
cd build
cmake -DLLVM_DIST_PATH=<Your LLVM install path> ..
make

The result pass module would be in build/lib

Usage

opt -load build/lib/LLVMRedundantStore.[so|dylib|dll] \
    -redundant-store -S test.ll -o=output.ll

Note: You need to use the opt in the same LLVM distribution you used to build this pass
