All of the existing RISC-V boards include hard-float support as well as QEMU. The FPGA cores we use at Cambridge also all support hard-float. My understanding is that glibc doesn't bother supporting soft-float on RV64. If no one is using it (and has no plans to use it), then I propose we drop it in 14.0 and save one more buildworld from make tinderbox. -- John Baldwin
