Question
On an ARMv7-M processor, assuming that [R1] = 0x7F0E0C2D, [R2] = 0x2468ACE0, [R3] = 0x1048B3C5, [N-bit] = 0, [Z-bit] = 0, [C-bit] = 1, [V-bit]
On an ARMv7-M processor, assuming that [R1] = 0x7F0E0C2D, [R2] = 0x2468ACE0, [R3] = 0x1048B3C5, [N-bit] = 0, [Z-bit] = 0, [C-bit] = 1, [V-bit] = 0, predict the 32-bit [R1] and all four condition flags in APSR after an ARM arithmetic/logical instruction is executed in EACH case. (These instructions are NOT executed one after the other one; instead, each instruction starts with the initial conditions given in the statement.)
(a) ADCS R1, R3, ROR #0x18
(b) ADDW R1, R2, #0xF1B
(c) SUBS R1, R2, R3
(d) RSBS R1, R2, #0x12
(e) SBCS R1, R3, LSL #12
(f) EORS R1, R2, R3, LSR #4
(g) BICS R1, R2, R3, RRX
(h) ANDS R1, R2, ASR #28
(i) ORR R1, R2, R3
(j) ORN R1, R2, #0xB600B600
