/* 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 ®[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.
