Ожидается ";" вместо "::" во встроенном ассемблере [закрыто] ⇐ C++

[Anonymous]

I try to run a code which has a random number generation algorythm as a part of it. However, it doesn't work and compiler warns: "expected a ";"" where :: for input and output operands in inline assembler shall be. For similar function dealing not with AVX but with SSE there is no mistake, the only difference I see is naming for instructions, not the function syntax. I will be very grateful for any hint why it goes wrong. Function code below, error in last line:

There vere multiple errors from compiler as it did not understand original "asm volatile", there was also an issue with attribute((aligned())) which it did not understand so I found that adding this define makes error leave
#define __attribute__(x)
