1) Modify the final() in final.c to emit some code before ld and st before outputting the assembly. 2) Modify the MD file. Find the template which generate ld or st, and add some code before ld and st.

Hi, I am working on gcc 4.1.1 and Itanium2 architecture. I want to use gcc to emit some code before each ld and st instruction (I know that using dynamic binary translator like PIN may be more suitable for this task, but I am on the way of studying gcc and want to use it to achieve this goal). But after several days of study, I find that the back-end of gcc too complex... :-( So, what is the best level in back-end to accomplish this task? I would appreciate any help I can get on this problem! thx!
