| # This file sets up a CMakeCache for the simple VE build. | ||

| # VE is a CPU with vector engine. But it is a connected to a host CPU as | ||
| # an accelerator. So, we compile programs for VE on a host using clang/llvm | ||
| # as a cross compiler. Therefore, the purpose of this cache file is to | ||
| # compile clang/llvm supporting both targets. | ||
