Do you want to base your decision on the CPU of the build host?
Or are you looking for an efficient way to implement the
runtime check?

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.
