Thanks.



================
Comment at: lib/Target/ARM/ARMBaseInstrInfo.cpp:2766
     if (I == B)
       // The 'and' is below the comparison instruction.
+      break;

For what it's worth, I believe the 'and' refers to the block at the beginning of the function, which can set MI to be equal to an 'and'.  But I agree that this comment is confusing, so I'll remove it.
