Fixed invalid mpy instruction being generated Fixed byte order of 32 bit values when emitted to the elf file Support for addv/subv to modify 16 bit registers directly Support for move 8bit immediate Support for tst0 instruction Support for directly adding p0 to an ab register after mpy Support for 8 bit immediate multiply Support for modr instruction Support for post increase/decrement for loads and stores Use copy instruction for a to a register moves
