I remember the awful days of fake hard-float support in ARMv4. Trapping to the kernel and doing soft float there was was 10x worse than just doing soft float in userspace in the first place.
Now, imagine doing that for xor-and-rotate, or bitfield insert/extract. Or leading zero count, or indexed memory access.
No. Thanks.
