Consider the following Java constructs. Express each in ARM assembly language. Assume all variables are singlebit Booleans and are in registers r0 = A, r1 = B, r2 = C, r3 = D. Note. The Java operators &, ¦, ! are AND, OR, and NOT, respectively. The operators && and || are AND and OR operators that support short?circuit evaluation; that is, if the expression yields false (AND) or true (OR) further evaluation is halted.
a. A = (B & C) | (!D);
b. A = (B && C) || (!D);
a. AND r0,r2,r3 ;A = B&C
NOT r4,r4 ;D = !D
ORR r0,r0,r4 ;A = (B & C)|(!D)
b. AND r0,r2,r3 ;A = B&&C check
NOTNE r4,r4 ;D = !D
ORRNE r0,r0,r4 ;A = (B & C)|(!D)
