No. Unless you count MEM. > P.S.: If you would be so kind as to jot down a sentence or two as to > what GIMPLE (some other frontends' tree?) is and how it relates to > SIMPLE (C frontend tree representation) I would REALLY appreciate it! > Ditto for something called SSA? GIMPLE is the representation used by the middle-end. GENERIC is the tree representation used by the C and C++ frontends, and also used by GIMPLE for operands and types. Both the C and C++ frontends extend GENERIC with frontend specific tree codes; thus, both frontends use a tree representation, and GENERIC is the shared subset of their tree representations. SIMPLE is a different intermediate representation used by a different compiler, which influenced the designed of GENERIC and then GIMPLE used by gcc. SSA is a compiler optimization technique which heavily influences the design of the intermediate representation. See http://en.wikipedia.org/wiki/Static_single_assignment_form . Ian
