[PATCH] D103629: [AArch64] Cost-model i8 vector loads/stores

[Sjoerd Meijer via Phabricator via llvm-commits]

SjoerdMeijer updated this revision to Diff 355862.
SjoerdMeijer added a comment.

With the codegen optimised for i8 loads in D105110 <https://reviews.llvm.org/D105110> so that it only takes a few instructions to materialise i8 loads, it's time to return to the cost-modelling part here.

I got rid of the logic that calculates the cost and have replaced it with a look-up table that is based on this new codegen.
