Thread: C Programming and Assembly

Hello, if anyone knows about assembly and C, I would appreciate you to help me in this:
Let's say I have the following assembly codes:

Code:

F1:
lea ex, [0+rdi*16]
ret

F2:
movzx eax, BYTE PTR [rdi+4]
ret

F3:
mov eax, DWORD PTR [rdi+16]
ret

F4:
mov eax,edi
sal eax,2
ret

Now I have the following C codes:

int scooby(int* a){
return a[4];
}

int scrappy(char*a)
{
return a[4];
}

Which assembly function corresponds with its C function?

gcc -c -s prog.c
and take a look at what the compiler produces.
