Pre-requisite to run the halide benchmark:
To make sure we are using the upstream build LLVM
$export LLVM_ROOT=/local/mnt/workspace/build/community_halide/llvm-install
$export LLVM_CONFIG=/local/mnt/workspace/build/community_halide/llvm-install/bin/llvm-config
To build the example
$cmake -DHalide_TARGET=host-hvx-hvx_v65 -DCMAKE_PREFIX_PATH=/local/mnt/workspace/build/community_halide/Halide/install .
$make all
To run this test, we need HL_HEXAGON_SIM_REMOTE and LD_LIBRARY_PATH to be set appropriately
$export ROOT_DIR=/local/mnt/workspace/build/community_halide/Halide
$export HL_HEXAGON_SIM_REMOTE=$ROOT_DIR/src/runtime/hexagon_remote/bin/v65/hexagon_sim_remote
$export HL_HEXAGON_TOOLS=/local/mnt/workspace/Qualcomm/Hexagon_SDK/5.2.0.0/tools/HEXAGON_Tools/8.7.0/Tools/
$export LD_LIBRARY_PATH=$HL_HEXAGON_TOOLS/lib/iss:$ROOT_DIR/src/runtime/hexagon_remote/:$LD_LIBRARY_PATH
To run this test
$ctest -R hexagon_benchmark_app
