67 * The order is defined by the stmts instruction. r0 is stored first,

70 * Registers 0-12 are general-purpose registers (r12 is normally used for
71 * the function return value).
72 * Register 13 is the stack pointer
73 * Register 14 is the link register
74 * Register 15 is the program counter (retrieved from the RAR sysreg)
