Question
Consider the following code, in which we have omitted the expression being
computed:
short scale3(short x, short y, short z) {
short t =
return t;
}
Compiling the actual function with gcc yields the following assembly code:
short scale3(short x, short y, short z)
x in %rdi, y in %rsi, z in %rdx
scale3:
leaq (%rsi,%rsi,9), %rbx
leaq (%rbx,%rdx), %rbx
leaq (%rbx,%rdi,%rsi), %rbx
ret
Fill in the missing expression in the C code. Show your work also.
