Hello,

I do not have my ARM-ARM with me anymore and I am hoping someone here
can help answer the following question.

If word @0 is 0x12345678, word at @4 is 0, and r0 contains 1, what
should be the contents of r0 (and r1) after executing "ldr r1, [r0], #4"?

Thanks in advance.

ldr from 1 is undefined, on most ARM I saw you get 0x12345600 or an
abort.
So the contents of r0 is as well undefined.
 From heart: ldr rn,[rm],#x : rn = *rm; rm += x;
