  Oh for sure, it'd be better to develop ARMv8 specific code on ARMv8. Having the ability to use ~28 64 bits registers (32 - special ones), instead of ~10 (or 7 in Thumb2) 32 bits registers is clearly a...

  I too would like to know. We have legacy ARMv7 code that runs correctly. The question then becomes is it worth the effort to convert all that code to ARMv8. Will there be a significant performance improvement...
