instructions (slow and expensive) to transfer data between the FPRs and
the GPRs. Also, because SimpleV needs efficient scalar instructions in
order to generate efficient vector instructions, adding new instructions
-for data-transfer/conversion between FPRs and GPRs seems necessary.
+for data-transfer/conversion between FPRs and GPRs multiplies that cost.
In addition, the vast majority of GPR <-> FPR data-transfers are as part
of a FP <-> Integer conversion sequence, therefore reducing the number
