Need help writing these in ARM 7 assembly.

1.uint64_t add64(uint32_t x, uint32_t y) // returns x + y; worth 10 points

2.uint64_t sub64 (uint64_t x, uint64_t y) // returns x -y

3.uint8_t minU8(uint8_t x, uint8_t y) // returns the minimum of x, y

4.int16_t minS16(int16_t x, int16_t y) // returns the minimum of x, y

5.bool isLessThanU8(uint8_t x, uint8_t y) // returns 1 if x < y, 0 else

6.bool isLessThanS16 (int16_t x, int16_t y) // returns 1 if x < y, 0 else

7.uint16_t shiftLeftU16 (uint16_t x, uint16_t p) // returns x << p = x * 2pfor p = 0 .. 31

8.uint32_t shiftU32(uint32_t x, int32_t p) // return x * 2pfor p = -31 .. 31

9.int8_t shiftS8(int8_t x, int8_t p) // return x * 2pfor p = -31 .. 31

10.bool isEqualU8(uint8_t x, uint8_t y) // returns 1 if x = y, 0 if x != y

11.bool isEqualS16(int16_t x, int16_t y) // returns1 if x= y, 0 if x != y
