[PATCH] D90445: [SLP] Make SLPVectorizer to use `llvm.masked.gather` intrinsic

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.

It appears this is causing a ~2-3% regression on AArch64 for some benchmarks, including `CINT2000/256.bzip2`. Any ideas? It might be caused by underestimating the cost of gather/scatter on AArch64.
