For the x86\_64 ADD instruction, generate a C program with inline assembly that calls each valid signature of this assembly instruction according to the Intel manual
user
the x86_64 `add` instruction has several variations based on the operands. here's a c program that demonstrates inline assembly usage for various valid signatures of the add instruction according to the intel manual.

```c
#include <stdio.h>

int main() {
    unsigned char immediate = 1;
    unsigned char src = 3;
    unsigned char dest = 2;

    // add r/m8, r8
    asm volatile("add %%cl, %%al"
                 : "=a"(dest)
                 : "a"(dest), "c"(src));

    printf("add r/m8, r8: 2 + 3 = %hhu\n", dest);

    unsigned short src16 = 250;
    unsigned short dest16 = 500;

    // add r/m16, r16
    asm volatile("add %%cx, %%ax"
                 : "=a"(dest16)
                 : "a"(dest16), "c"(src16));

    printf("add r/m16, r16: 500 + 250 = %hu\n", dest16);

    unsigned int src32 = 99999;
    unsigned int dest32 = 100001;

    // add r/m32, r32
    asm volatile("add %%ecx, %%eax"
                 : "=a"(dest32)
                 : "a"(dest32), "c"(src32));

    printf("add r/m32, r32: 100001 + 99999 = %u\n", dest32);

    unsigned long long src64 = 12345678901234;
    unsigned long long dest64 = 98765432109876;

    // add r/m64, r64
    asm volatile("add %%rcx, %%rax"
                 : "=a"(dest64)
                 : "a"(dest64), "c"(src64));
                 
    printf("add r/m64, r64: 98765432109876 + 12345678901234 = %llu\n", dest64);

    unsigned char immediate_dest = 5;

    // add r/m8, imm8
    asm volatile("add %1, %0"
                 : "=rm"(immediate_dest)
                 : "ir"(immediate), "0"(immediate_dest));

    printf("add r/m8, imm8: 5 + 1 = %hhu\n", immediate_dest);

    unsigned short immediate_dest16 = 350;

    // add r/m16, imm16
    asm volatile("add %1, %0"
                 : "=rm"(immediate_dest16)
                 : "ir"((short)immediate), "0"(immediate_dest16));

    printf("add r/m16, imm16: 350 + 1 = %hu\n", immediate_dest16);

    unsigned int immediate_dest32 = 75000;
    
    // add r/m32, imm32
    asm volatile("add %1, %0"
                 : "=rm"(immediate_dest32)
                 : "ir"(immediate), "0"(immediate_dest32));

    printf("add r/m32, imm32: 75000 + 1 = %u\n", immediate_dest32);

    unsigned long long immediate_dest64 = 8000000000000;

    // add r/m64, imm32
    asm volatile("add %1, %0"
                 : "=rm"(immediate_dest64)
                 : "ir"((int)immediate), "0"(immediate_dest64));

    printf("add r/m64, imm32: 8000000000000 + 1 = %llu\n", immediate_dest64);

    return 0;
}
```

make sure to compile the code with the `-masm=intel` flag if you're using gcc:

```
gcc -masm=intel -o add_example add_example.c
```

this program demonstrates the use of register-to-memory, memory-to-register, and immediate add operations with various register sizes, including 8-bit, 16-bit, 32-bit, and 64-bit.
