/* Before #including this file, the following macros should be defined:
 *
 * PCADDR: Program counter (memory address of the current instruction).
 *
 * ADD_TO_PC(x): Increment the program counter in 'x' instructions.
 * This is only used for small changes to PC, so the new program counter
 * is guaranteed to fall in the current cached interpreter or dynarec block.
 *
 * DECLARE_INSTRUCTION(name)
 * Declares an instruction function which is not a jump.
 * Followed by a block of code.
 *
 * DECLARE_JUMP(name, destination, condition, link, likely, cop1)
 * name is the name of the jump or branch instruction.
 * destination is the destination memory address of the jump.
 * If condition is nonzero, the jump is taken.
 * link is a pointer to a variable where (PC+8) is written unconditionally.
 *     To avoid linking, pass &reg[0]
 * If likely is nonzero, the delay slot is only executed if the jump is taken.
 * If cop1 is nonzero, a COP1 unusable check will be done.
 *
 * CHECK_MEMORY(): A snippet to be run after a store instruction,
 *                 to check if the store affected executable blocks.
 *                 The memory address of the store is in the 'address' global.
