A few comments; more to come after the earlier patches land.


Is this deliberately incomplete?
Comparing to N4755 - I see:

The member type shall be present if and only if:

  • T is a vectorizable type, and
  • simd_abi::fixed_size<N> is supported (see 9.2.1), and
  • every type in the Abis pack is an ABI tag.

Will a later patch fix this up?


We don't need the comments any more that P0820 has been adopted.


Isn't this now named split?
