How to Build It

This is how I build it now. The commands assumes:

• ROCm stack is already installed
• ROCm-Device-Libs is built, and installed at ~/hcc/ROCm-Device-Libs/build/dist
• N is the number of threads available for make

git clone --recursive -b clang_tot_upgrade git@github.com:RadeonOpenCompute/hcc.git hcc_upstream
mkdir build_upstream
cd build_upstream
cmake \
    -DCMAKE_BUILD_TYPE=Release \
    -DHSA_AMDGPU_GPU_TARGET=gfx803 \
    -DROCM_DEVICE_LIB_DIR=~/hcc/ROCm-Device-Libs/build/dist/lib \
    ../hcc_upstream
make -jN world
make -jN
