We're talking OpenCL, right? Since there's the -cl-strict-aliasing option in OpenCL 1.0 spec, it sounds like strict aliasing isn't assumed in OpenCL by default. However, this option is gone in 1.1+, so maybe strict aliasing is assumed by default in 1.1+? We need to figure this out, if we haven't already.
