Title: Help: RAM Write with ASM for a specific instruction
Post by: Bully@Wiiplaza on May 08, 2011, 08:52:49 PM
Hey,
it would be great if someone could provide me a RAM Write template for this instruction: lwzx rX, rY, rX!

For lwzx rX, rY, rZ the template would be:

Code Select
lis rX, 0xVVVV
ori rX, rX, 0xWWWW
stwx rX, rY, rZ

But this time, the destination and source register is the same.

Thx for answers.

lwzx r0,r4,r0

generally:
Code Select

lis r12, 0xVVVV
ori r12, r12, 0xWWWW
stwx r12, rY, rX
lwzx rX, rY, rX
