   // If this is an 'and R, 1234' where the operation is AND/OR and the RHS is
-  // a constant without a predicate fn that has more that one bit set, handle
+  // a constant without a predicate fn that has more than one bit set, handle
   // this as a special case.  This is usually for targets that have special
   // handling of certain large constants (e.g. alpha with it's 8/16/32-bit
   // handling stuff).  Using these instructions is often far more efficient
   // than materializing the constant.  Unfortunately, both the instcombiner
   // and the dag combiner can often infer that bits are dead, and thus drop
   // them from the mask in the dag.  For example, it might turn 'AND X, 255'
   // into 'AND X, 254' if it knows the low bit is set.  Emit code that checks
   // to handle this.
