Question

. You are given the following information. A function with prototype 

int mystery(int a, int b, int c, int d); 

is compiled into assembly code. The body of the code is as follows: 

leal (%rdi,%rsi,2), %eax 

leal (%rdx,%rdx,2), %edx

addl %edx, %eax 

leal (%rax,%rcx,4), %eax 

ret 

Assume a at rdi, b at rsi, c at rdx, d at rcx, and the return value at eax. 

Write the C code for mystery function that will have an effect equivalent to the assembly code  above. 

Please dont copy and paste.
