The function `tensorDataFromMemRef` reading elements from a result memref and copying them to an instance of `TensorData` fails to handle memrefs with non-zero offsets as it adds the offset twice when calculating indexes. This may result in out-of-bounds memory accesses and incorrect results. This patch fixes the calculation of indexes by removing the second addition of the offset.
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_internal
cd concrete_internal
git checkout engine_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_INTERNAL_PROJECT"
make build-initialized
Build the compiler
make concretecompiler
Test the compiler
#TODO: let cmake set this PATH
export LD_LIBRARY_PATH="path_to_concrete-compiler/compiler/build/lib/Runtime/"
make test
