[PATCH] D159283: Add intrinsic to count trailing zero elements in a vector

[Paul Walker via Phabricator via llvm-commits]

Yes I believe D158291 <https://reviews.llvm.org/D158291> will set the zero is poison bit because the transformation already has to handle the zero case for its quick loop path.  At which point I'd expect this patch to be updated accordingly so the SVE code generation remains unaffected.
