[PATCH] D123100: [Support/Hash functions] Change the `final()` and `result()` of the hashing functions to return an array of bytes

[Amir Ayupov via Phabricator via llvm-commits]

Amir added inline comments.


================
Comment at: bolt/lib/Core/DebugData.cpp:823
     Hasher.update(AbbrevData);
-    StringRef Key = Hasher.final();
+    auto Hash = Hasher.final();
+    StringRef Key((const char *)Hash.data(), Hash.size());
----------------
I think it would be more in line with LLVM coding standards to expand `auto` in this case (and others) – see https://llvm.org/docs/CodingStandards.html#use-auto-type-deduction-to-make-code-more-readable. 
My understanding is that `auto` is fine where the type is obvious from the context (is explicitly available on the same line e.g. with casts), is abstract (T::iterator types), or doesn't matter (e.g. lambdas).
