[PATCH] D117457: [DAG] Extend SearchForAndLoads with any_extend handling

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

Oh I see yes. That is essentially the same as the multiple_load_or case here - I was trying to get that to go wrong but couldn't. On AArch64 we implicitly zext (in the `orr w0, w9, w8`, the top bits of x0 are set to 0 as it writes w0). In the case you have it doesn't get the zext.

I will try and sort out a fix, and make sure this is either fixed or reverted on the branch (depending on which revision that gets created from).
