Which is the > mechanism? I'm sorry I don't understand the question. Converting from IR to another is more or less straightforward. The C frontend starts with a C frontend specific representation that is really just GENERIC plus some language-specific tree codes. The C++ frontend is similar. That representation is translated into GENERIC, then into GIMPLE, then back into GENERIC (don't ask), then into RTL, and finally the compiler generates assembler. Ian
