[I didn't see the original post, just the quote in a reply] Another reason for making floating point and integer registers the same: you can use the mantissa multiplier of your FPU to do integer multiplication. Rather than having a true multiplier in your floating point unit, and multiply step instructions in your integer unit, as most RISC systems with separate integer and floating point units, and register sets, do.
