For this kind of question, why don't you try it and find out? The source code and the compiler are right there. SSA_NAME_DEF_STMT will always return a pointer to a tree node. That tree node will sometimes be a PHI_NODE, and will sometimes be a MODIFY_EXPR. There may be other possibilies; I'm not sure offhand. > Is there any function/macro available to find it? I don't understand this question. Ian
