App-Compiler

Frontend application compiler that generates CDFG from C code based on LLVM

Getting Started

Dependencies

1. LLVM-10.0.0 with Polly included

2. CMake

3. C++-17

LLVM with Polly

1. download llvm source codes from https://github.com/llvm/llvm-project/archive/refs/tags/llvmorg-10.0.0.tar.gz

   extract and change directory name

    tar xvf llvmorg-10.0.0.tar.gz
    mv llvmorg-10.0.0 llvm-project-10.0.0

2. build llvm

    mkdir llvm-10.0.0-built
    cd llvm-project-10.0.0
    mkdir build
    cd build
    cmake -DLLVM_ENABLE_PROJECTS='polly;clang' -G "Unix Makefiles" ../llvm
    # multi-thread consumes lots of memory, e.g. -j4 : 30G+
    make -j4
    # DESTDIR set install directory
    make install DESTDIR=/xxx/llvm/llvm-10.0.0-built

3. set llvm env

    # add following env to .bashrc and then source ~/.bashrc.
    # or directly export the env
    export LLVM_HOME=/xxx/llvm/llvm-10.0.0-built/usr/local/bin
    export PATH=$LLVM_HOME:$PATH
    # or set the LLVM path in the CMakeLists.txt
    set(LLVM_INCLUDE_DIRS "/xxx/llvm-10.0.0-built/usr/local/include")
    set(LLVM_LIBRARY_DIRS "/xxx/llvm-10.0.0-built/usr/local/lib")

Build

Using the script build.sh in this app-compiler directory

./build.sh
