 // This file implements the LiveRange and LiveInterval classes.  Given some
 // numbering of each the machine instructions an interval [i, j) is said to be a
 // live interval for register v if there is no instruction with number j' > j
-// such that v is live at j' abd there is no instruction with number i' < i such
+// such that v is live at j' and there is no instruction with number i' < i such
 // that v is live at i'. In this implementation intervals can have holes,
 // i.e. an interval might look like [1,20), [50,65), [1000,1001).  Each
 // individual range is represented as an instance of LiveRange, and the whole
