Well I'm not a MIPS expert, but I was thinking doing something like this:

moveIntsToDouble(src_t1, src_t2, dst_fp1):
  mtc1   src_t1, dst_fp1
  mthc1  src_t2, dst_fp1

moveDoubleToInts(src_fp1, dst_t1, dst_22):
  mfc1   dst_t1, src_fp1
  mfhc1  dst_t2, src_fp1



This should work (I think at least) if the fp registers are 64bit wide. Am I right?
