    Dalvik opcodes


    Author: Gabor Paller


    Vx values in the table denote a Dalvik register. Depending on the instruction， 16， 256 or 64k registers can be accessed. Operations on long and double values use two registers， e.g. a double value addressed in the V0 register occupies the V0 and V1 registers.

    Boolean values are stored as 1 for true and 0 for false. Operations on booleans are translated into integer operations.

    All the examples are in hig-endian format， e.g. 0F00 0A00 is coded as     0F， 00， 0A， 00 sequence.

    Note there are no explanation/example at some instructions. This means that I have not seen that instruction in the wild and its presence/name is only known Android opcode constant list.
