I think ARMv8 is going to be an important platform for us in the next few years, so ld128 is not just for SPARC (I'd also like us to switch to ld128 on PowerPC, since that's the ABI that everyone else uses, but I don't anticipate PowerPC becoming tier 1 any time soon, whereas I would very much like to see ARMv8 become tier 1 within a year of shipping silicon). That's not to say that we should hold things up waiting for ld128 versions, just that adding ld128 versions soon after adding ld80 ones would be very helpful.
