As far as I understood:

• %rdi = 1st argument = x
• %rsi = 2nd argument = y
• %rdx = 3rd argument = z
• The others manipulate these registers... and store in a return value register

The 3rd line on the assembly code leaq (%rsi, %rsi, 2), %rdx, which as I translate it: z = y + 2*y.

I'm confused, is this code wrong, or is it an assembly magic?
