We would like to use the cache pruning in one of our downstream tools but we would like to use a custom prefix.



================
Comment at: llvm/include/llvm/Support/CachePruning.h:78
+bool pruneCache(StringRef Path, CachePruningPolicy Policy,
+                Twine Prefix = "llvmcache");
 
----------------
Alternatively, we could also make this a part of `CachePruningPolicy`, I'm not sure if that would be preferable?
