I'm just trying to get a clear understanding of the store and store with update commands, the store with update don't seem to be working for me as I thought they would.
When I store a byte, word or long word with the store and update command shouldn't the register that contains the store address then automatically increase by the size of the data stored?
Eg....lets assume I set up an address in r9 as 0x60010000
sthu r5,0(r9) = Store word in r5 to 0x60010000, and automatically increment (update) r9 by 2 as we stored a word (so r9 now = 0x60010002)
stbu r5,0(r9) = Store byte in r5 to 0x60010000, and automatically increment (update) r9 by 1 as we stored a byte (so r9 now = 0x60010003)
Is that correct on how those commands works?
Currently I am manually adding to the address in r9 after a stb or sth like so:
sth r5,0(r9) = Store word in r5 to 0x60010000
addi r9,r9,2 = increment (update) r9 address by 2 as we stored a word (so r9 = 0x60010002)
Obviously that isn't very efficient if I need to store multiple things.
