Description
Problem Description
Building QMCPACK using the amdclang in rocm 7.2 gives me tons off lld warning
ld.lld: warning: <unknown>:0:0: in function __omp_offloading_26_36d5ad__XXXXXX local memory global used by non-kernel function
Here is the reproducer
In build directory,
git clone --depth=1 https://github.com/QMCPACK/qmcpack.git
cd qmcpack/build
cmake -DCMAKE_C_COMPILER=amdclang -DCMAKE_CXX_COMPILER=amdclang++ -DQMC_MPI=OFF -DQMC_GPU=openmp -DQMC_GPU_ARCHS=gfx90a ..
cd src/QMCWaveFunctions
make -j32
Not sure what changed between 7.1 and 7.2.
