--- Comment #1 from Sebastian Dröge (slomo) <slomo at coaxion.net> ---
There should be endianness conversion fast-paths, implemented in C. A useful
compiler should already optimize them quite well, possibly even using SIMD
instructions.

Once that is there, we can consider adding ORC optimizations for those if it
actually makes a performance difference over the C code with an optimizing
compiler.


Adding actual platform specific assembly should be only the very last resort,
if nothing else works and it brings a big performance improvement.
