[PATCH] D136169: [AMDGPU] Avoid SCC clobbering before S_CSELECT_B32

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added a comment.

For the loop which may potentially consume a lot of time I'd suggest to set a small scan threshold and assume scc is used otherwise. This relies on the possibility of restoring scc without scavenging, like in my previous comment.
