You should be able to test that InstCombine does not perform the strrchr -> memrchr fold if a macos triple is given.



================
Comment at: llvm/lib/Analysis/TargetLibraryInfo.cpp:206
     TLI.setAvailable(LibFunc_putchar_unlocked);
+    TLI.setUnavailable(LibFunc_memchr);
 
----------------
Isn't this supposed to be memrchr?
