A little help with assemply

A little help with assemply

A little help with assemply

Hi , I need to write a program that will have to following
register values in the end :

R3           0x0000_0000
R4           0x0000_B000
R5           0xA000_1000

and the code I wrote is :

void main()

     asm {
         xor r3,r3,r3
         addi r3,r3,0x0000
         xor r4,r4,r4
         addi r4,r4,0x0000B000
         xor r5,r5,r5
         addi r5,r5,0xA0001000
         } // end of ex

I'd appreciate corrections and everything you can think of

thanks :)

RE: A little help with assemply

my knowledge is highly obsolete (last, and only assm clas was 16-bit and 1985, prob'ly before you existed) so please pardon my ignorance. I am assuming that the three register references (per op) is for 32-bit. if so, wouldn't you need four ref.s in order to zero the entire reg?
my version was something like:

xor r3,r3,r3,r3
#not really needed since r3 already zeroed.
addi r3,0x00000000

xor r4,r4,r4,r4
addi r4,0x0000000B
xor r5,r5,r5,r5
addi r5,0xA0001000

but like i said, i'm real "over the hill" so disregard arrant ignorance
