// This implements NewValueJump pass in Hexagon.
// Ideally, we should merge this as a Peephole pass prior to register
-// allocation, but becuase we have a spill in between the feeder and new value
+// allocation, but because we have a spill in between the feeder and new value
// jump instructions, we are forced to write after register allocation.
-// Having said that, we should re-attempt to pull this ealier at some piont
+// Having said that, we should re-attempt to pull this earlier at some point
// in future.
// The basic approach looks for sequence of predicated jump, compare instruciton
