All results in code compiled by zamacompiler are passed as return values, which means that all tensors passed as function arguments are constant inputs that are never written. This patch changes the arguments used as data pointers for input tensors in `JITLambda::Arguments::setArg()` from `void*` to `const void*` to emphasize their use as inputs and to allow for constant arrays to be passed as function inputs.
Building the compiler
Install MLIR following https://mlir.llvm.org/getting_started/ Use commit c2415d67a564
Install pybind11:
pip install pybind11
Build concrete library:
git clone https://github.com/zama-ai/concrete
cd concrete
git checkout feature/core_c_api
cd concrete-ffi
RUSTFLAGS="-C target-cpu=native" cargo build --release
Generate the compiler build system, in the build directory
export LLVM_PROJECT="PATH_TO_LLVM_PROJECT"
export CONCRETE_PROJECT="PATH_TO_CONCRETE_PROJECT"
make build
Build the compiler
make zamacompiler
Test the compiler
#TODO: let cmake set this PATH
export LD_LIBRARY_PATH="path_to_homomorphizer/compiler/build/lib/Runtime/"
make test
Run the compiler
