================
Comment at: lib/Target/X86/X86FixupLEAs.cpp:633
+        if (MF.getSubtarget<X86Subtarget>().slowLEA())
+          processInstructionForSNBPlus(I, MFI);
+        else
----------------
Is it a good idea to directly associate a general (and very vague....) feature bit with a specific set of targets like this?
