--- Comment #1 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
part 1:

In Horizontal-First Mode this would use data-dependent fail-first Mode,
which would test and truncate VL at the point where a[i] was less than m,
creating a CR Vector in the process (sv.cmp.)

part 2:

SVP64 Branch new CTR Mode would skip over all elements that
failed, decrementing CTR in the process.

part 3:

a second data-dependent ffirst would test and truncate
VL where a[i] was GREATER-EQUAL than m

part 4:

a second branch CTR mode would likewise loop and decrement CTR
