The dependencies in the code snippet are as follows:
1. Data dependency:
- The instruction "DIV R4, R1, R5" depends on the result of the instruction "ADD R1, R2, R3" because it uses the value of R1 as one of its operands.
2. Output dependency:
- The instruction "ADD R5, R7, R4" depends on the result of the instruction "DIV R4, R1, R5" because it uses the value of R4 as one of its operands.
3. Anti-dependency:
- The instruction "AND R5, R4, R2" depends on the result of the instruction "ADD R5, R7, R4" because it uses the value of R5 as one of its operands.
