[PATCH] D128065: [AArch64][SVE] Fold target specific ext/trunc nodes into loads/stores

[Bradley Smith via Phabricator via llvm-commits]

bsmith updated this revision to Diff 445477.
bsmith added a comment.

- Rename InVT to VT for clarity.
- Check for zero return from `getNumElementsFromSVEPredPattern`.
- Bail out if passthru is not zero or undef.
- Force passthru to be zero so as to not introduce extra undef bits.
