Good questions. Yeah, the answer can't be generally known at 
compile time. But can be interesting in the specific case (i.e. 
when I can control both the build machine and the one it will 
eventually run on). The function in the example is a flag similar 
to core.cpuid.avx (http://dlang.org/phobos/core_cpuid.html#.avx).

Was mainly looking for some feedback on the plans for the scope 
of CTFE in regards to assembly language.

Thanks for the input.
