    Maybe it is a grafik or an ARM code.
    That's what I thought at first too. But it all makes sense:
    • The function pushes registers in the first line
    • The function pops registers in the last line
    • The registers are popped to the positions they were pushed from except for lr/pc of course.
    • The stack-pointer is decreased and then used to the limit. (Why allocate more or less?)
    • The cmp-opcode is followed by a beq-opcode.
    • The functions called from this function are valid too.

    It *has* to be THUMB-Code!
