backpathching algorithm

hi...i wanted to implement backpatching algorithm in c++...
but am not sure the way i shud proceed....

can some one give me the approach or pseudocode on backpatching
eg
x<y or y<z
then the three address code before backpathcing
is
if x<y goto------
goto----
if y<z goto------
goto-----

can someone give me the approach

Did you not ask this very question about half an hour ago somewhere else on this board? This is not one of those "how do I write a for-loop that counts to 100 in steps of 4" type question that half the board can answer. Give someone who knows a chance to see the question...
