Identify the error in this ARM assembly snippet:
BNE
MOV r0, #1
AMissing label after BNE
BMOV instruction syntax error
CBNE cannot be used with MOV
DNo error
Step-by-Step Solution
Solution:

  1. Step 1: Check BNE instruction format

    BNE requires a label to branch to; here it is missing.

  2. Step 2: Verify MOV instruction

    MOV syntax is correct; no error there.

  3. Final Answer:

    Missing label after BNE -> Option A

  4. Quick Check:

    Branch needs target label [OK]
Quick Trick: Branch instructions must have a target label [OK]
Common Mistakes:
  • Omitting label after branch
  • Misreading MOV syntax
  • Thinking BNE works without label
