ECX = -(va13 - vall) + (-val4 + val2) + 3 Assume that vall is 16-bit variable, val2 is 32-bit variable, val3 is 8-bit variable, and va14 is 8-bit variable. - You need to implement the expression the way it is provided, you cannot do any reduction on the expression while implementing it. -Initialize vall with 12 (decimal), val2 with 9 (decimal), val3 with 2 (decimal), val4 with 20 (decimal), You are NOT allowed to update the values stored in vall, val2, val3 and val4 Use mov, add, sub, movsx, movzx, or neq instructions whenever needed.

Name addressing modes in MC68000 that are not permitted as a destination are listed, along with the reasons why they are not allowed.

Consider the following instructions mov eax, 0xffffff45add eax, 45   AND   mov eax, 0xffffff45add eax, -45   Explain why, in each function, the SIGN FLAG is set to one. note: Assembly x86 instructions
