Hi, This series makes changes in vext_set_tail_elements_1s() to be a little nicer to the emulation.
First patch makes the function a no-op when vta == 0. Aside from the logic simplification we also have a little performance boost. Second patch makes the function debug only. The logic is explained in the commit message, but long story short: we don't have to implement any tail-agnostic policy at all to be spec compliant, but this function has its uses for debug purposes, so keeping it as a debug option allow users to disable it on demand. Patches are based on top of Alistair's riscv-to-apply.next.
