[PATCH] D43542: [CodeGen][FastRegAlloc] Disable registers spilling for a naked function (PR28641)

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

I'm still a bit confused as to why we start spilling unused input vregs in the first place. Can you add a test case so we can reproduce? (The test can't get commit without a test anyway)
