That does not make sense at all (IMHO). Variables bound to registers
need to be used on global level. Also, r30/r31 are not available for
that purpose.

Better explain your overall goal than trying to get the compiler into
generating exact the assembly code you want. If you want to program
in assembly language, don't use a compiler. If you want a compiler,
don't try forcing it to become an assembler.
