"It inspired movfuscator, the single instruction C compiler. Building on this, there is a branchless, mov-only version of the classic DOOM video game. This is thought to be entirely secure against the Meltdown and Spectre CPU vulnerabilities, which require speculative execution on branch instructions. The mov-only DOOM renders approximately one frame every 7 hours, so playing this version requires somewhat increased patience." This means, we need about twenty doublings of the computing speed to play it smoothly. Will we ever reach it? And if yes, when?
