...s built around pure C macros. Clover uses a slightly more complex system, involving a Python script "compiling" a set of built-ins into four files. For example, this declaration (REPL is a macro that does a simple for()) : ---- def vecf : float2 float3 float4 float8 float16 native $type acospi $vecf : x:$type     REPL($vecdim)         result[i] = std::acos(x[i]) / M_PI; end ---- Is compiled to these fragments, one for each vector type (float2, float3, etc) : ---- // In stdlib_def.h : what the OpenCL C kernel sees float2 OVERLOAD acospi(float2 x); // In stdlib_impl.h : what gets compil...
