| Jul 26, 2020 at 17:23 | comment | added | kelalaka | Is there any source of this code? If you wish I can extend this answer with disassembly. It clearly shows that there is no optimization around. | |

In Linux/GCC this function has 118 disassembly lines. Run the command objdump -Mintel -d a.out on the compiled output a.out.
