[Solved] Identify the error in this ARM code snippet:B label MOV R0, #1 label: MOV R1, #2 — Ans: Branch instruction syntax is correct, no error | ARM Architecture

ARM Architecture - Control Flow Instructions

Identify the error in this ARM code snippet:

B label
MOV R0, #1
label:
MOV R1, #2

ABranch instruction missing condition code

BBranch instruction syntax is correct, no error

CMOV instructions cannot follow a branch

DLabel is not defined before branch

Step-by-Step Solution

Solution:

Step 1: Check branch syntax
'B label' is a valid unconditional branch instruction in ARM assembly.
Step 2: Verify label and instruction order
The label 'label:' is defined after the branch, which is allowed. MOV instructions after branch are valid.
Final Answer:
Branch instruction syntax is correct, no error -> Option B
Quick Check:
Unconditional branch syntax is valid [OK]

Quick Trick: Unconditional branch needs only 'B' and label [OK]
