[PATCH] D129594: [InstrProf] Add options to profile function groups

[Ian Levesque via Phabricator via cfe-commits]

ianlevesque added inline comments.


================
Comment at: clang/lib/CodeGen/CodeGenModule.cpp:2871
+  if (NumGroups > 1) {
+    auto Group = llvm::MD5Hash(Fn->getName()) % NumGroups;
+    if (Group != getCodeGenOpts().ProfileSelectedFunctionGroup)
----------------
In D87953 I used crc32 to avoid computing an md5 hash on every function name.
