+  "available on %2 %3 or newer">;
 def note_silence_unligned_allocation_unavailable : Note<
   "if you supply your own aligned allocation functions, use "
----------------
I observe that this mnemonic is misspelled; but that's not this patch's fault.
The traditional spelling would probably be just `note_aligned_allocation_unavailable`.


================
Comment at: lib/Driver/ToolChains/Darwin.cpp:2027
+      isAlignedAllocationUnavailable())
     CC1Args.push_back("-faligned-alloc-unavailable");
 }
----------------
Peanut gallery asks: Why is the cc1 option spelled differently from the clang driver option? Don't they do the same thing?
