[PATCH] D151189: [AArch64] Increase the cost of i1 inserts / extracts

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

Hello. From looking at the precommit tests I had, they seem to show the opposite in libquantum. A small decrease in codesize, which in my testing had led to a performance improvement (but that may be a bit noisy). This would be O3 <https://reviews.llvm.org/owners/package/3/> or Ofast though.

I would expect this patch to cause less SLP vectorization, and that should usually cause a codesize to increase a little. But the amounts you mention are much bigger than I would expect from that. Maybe there is different inlining happening now?
