Hi 1) I want to do a loop transformation on SSA representation of a C program. ie) I have to add a loop induction variable to list of varibles and add a for loop. Are there any functions or macros to modify SSA representation of a program? In which file they have been declared? Thanks in advance. ___________________________________________________________ The all-new Yahoo!
