See file tcg/README which says this: The TCG "target" is the architecture for which we generate the code. It is of course not the same as the "target" of QEMU which is the emulated architecture. As TCG started as a generic C backend used for cross compiling, it is assumed that the TCG target is different from the host, although it is never the case for QEMU.

Just want to make sure. When we talk about target in TCG, that _always_ means the host, right? Regards, chenwj

Yes. See file tcg/README which says this:

The TCG "target" is the architecture for which we generate the code. It is of course not the same as the "target" of QEMU which is the emulated architecture. As TCG started as a generic C backend used for cross compiling, it is assumed that the TCG target is different from the host, although it is never the case for QEMU.
