By using such SIMD standards, programs can often speed up significantly. Good compilers are able to transform normal loops into such SIMD code automatically through a process called .

We can do that through the features field in our target specification. To disable the and sse features, we add them prefixed with a minus:

Fortunately, LLVM has support for a soft-float feature that emulates all floating point operations through software functions based on normal integers. This makes it possible to use floats in our kernel without SSE; it will just be a bit slower.
