[PATCH] D90247: [AArch64] Add legalizations for VECREDUCE_SEQ_FADD

[Cameron McInally via Phabricator via llvm-commits]

cameron.mcinally added a comment.

Comment from `ARM/ARMISelLowering.cpp`:

  // Custom Expand smaller than legal vector reductions to prevent false zero
  // items being added.
  setOperationAction(ISD::VECREDUCE_FADD, MVT::v4f16, Custom);

So it will probably take some work to truly unwind the 0.0 neutral element code. Just FYI...
