[Qemu-discuss] Qemu "-cpu host" option

What does Qemu do when invoked using "-cpu host" option that sets target CPU same as the host CPU?

Is it that when this option is used Qemu performs no binary translation? Because the target CPU is same as host CPU, code compiled for target CPU may run directly on host CPU.

Or does Qemu discover the configuration of host CPU, automatically use the most appropriate flag and cpu values, and use binary translation anyway?
