It might be acceptable to code this, assemble it, and then embed the
machine code as a (commented!) hexadecimal array in the
target-specific code for this platform.  Similar things are done for
code sequences that have to be synthesized by the linker - take a look
at e.g. elfxx-ia64.c's plt_* arrays.
