Morpher DFG Generator : LLVM-based Control Data-Flow Graph (CDFG) generator

CGRAs target loop kernels where the application spends significat fraction of the execution time. Morpher requires the user to annotate the specifica loop kernels to be mapped. Morpher DFG Generator extract the loop in an .xml file. Morpher supports control-divergence (i.e., existence of multiple control flow paths) inside the loop kernel through partial predication.

Build dependencies:

This version requires LLVM 10.0.0 and JSON libraries.

LLVM, clang, polly:

Read https://llvm.org/docs/GettingStarted.html follow https://github.com/llvm/llvm-project

git clone https://github.com/llvm/llvm-project.git
git checkout <correct version> (llvm10.0.0)
cd llvm-project
mkdir build
cd build
cmake -DLLVM_ENABLE_PROJECTS='polly;clang' -G "Unix Makefiles" ../llvm
make -j4
sudo make install

Important points:

make sure to checkout correct version before building
better to use gold linker instead of ld if you face memory problem while building: https://stackoverflow.com/questions/25197570/llvm-clang-compile-error-with-memory-exhausted
don't use release type use default debug version (will take about 70GB disk space)
