It's version 3.2. GetElementPtr still not implemented and C runtime library needs to borrow from GCC.

GetElementPtr is the equivalent of all the non-register addressing modes but can probably be implemented as LEA during the earlier stages and just merged later when the needed addressing mode is available and the pointer is used once.
