Please study the code.  A 32 bit MIPS ABI on a 64 bit MIPS represents 
long long as two 32 bit sub-parts of two 64 bit registers; the two 32 
bit parts are assumed to be adjacent.

The adjacent assumption will eventually be lifted, but that will be done 
by someone implementing something like location descriptions.
