[PATCH] D78634: AArch64: materialize large stack offset into xzr correctly.

[Oliver Stannard (Linaro) via Phabricator via llvm-commits]

ostannard added a comment.

Actually, if the destination is XZR, the adds won't have any effect, so surely we don't need to emit any instructions? Could we just early-return without emitting anything if `DestReg == XZR`?
