Hi,

changes from v3:

- Check if we support vec_cond_expr for the selected mode in case we
  need to set the inactive elements to zero.
- Add another undef operand to gcn.
- Remove unnecessary changes in i386 patch.

Robin Dapp (8):
  docs: Document maskload else operand and behavior.
  ifn: Add else-operand handling.
  tree-ifcvt: Add zero maskload else value.
  vect: Add maskload else value support.
  aarch64: Add masked-load else operands.
  gcn: Add else operand to masked loads.
  i386: Add zero maskload else operand.
  RISC-V: Add else operand to masked loads [PR115336].
