That idea is flawed because putting that string will make it optimize for an Intel chip, which will be worse than optimizing for an AMD chip because even though the compiler chooses the worst "optimized" option, it is still optimizing FOR that chip. -> The AMD optimization is optimized -But the Intel optimization is extra optimized (but not optimized for AM- only for itself).
Yes and no. I'm fairly certain that often the optimizations will be better than the fallback codepath in practice. This is especially true if you note that this is defeating the check for the vendor id, not defeating a lot of the other checks the dispatcher does.
