--- Comment #6 from Petr <kobalicek.petr at gmail dot com> --- Ok, that's fair enough. I didn't know GCC needs an additional option to switch to fully compatible Intel syntax. The code that I posted works fine in clang, so sorry about that. And yes, the instruction will #UD, but that was the point, initially :)
