Because the body has been split up into the basic blocks of the CFG. You need to use the basic block iterators to traverse the CFG (e.g., FOR_EACH_BB_FN()). > Because I am trying to traverse instructions from a C program thanks to MELT > (cf MELT branch) and I don't know if I have to traverse basic blocks with > FOR_EACH_BB_FN iterator or if there is another solution with gimple_body. > Basile believes that gimple_body is nearly useless. It is once the CFG has been built, yes. Diego.
