test.cl

When compiling a kernel dealing to complex math I had encountered a problem
that the compiler hangs. It hangs when llvm-based runtimes are used, no matter
cpu or gpu based. The problem is reproduced (on my machine) in both llvm-8 and
llvm-10 based runtimes, more precisely cpu and gpu llvm-8 Mesa Clover runtimes
installed from Ubuntu disco packages and llvm-10-based (llvm-10 and clang-10
are installed from apt.llvm.org) self-compiled pocl (with the patches making it
compatible to llvm 10).

On Windows the kernels have been built successfully using AMD APP SDK (I
haven't tried pocl).</pre>
