That works quite well for now. Of course, if qemu is suddenly ported to a new
CPU arch, then it is likely that the new op.s file needed would have to be
hand coded. Still, a reasonable compromise.

It is not. GPL only applies to derived code. Generated code is derivied from
what you right, not from the gcc source code, and thus the GPL doesn't apply
to it. So the op.s files would share the same copyright as the original op.c
file.

QEMU uses BSD/MIT license for the system emulator.
It is qemu-user (the linux only one) which is GPL.

Infinite complexity begets infinite beauty.
Infinite precision begets infinite perfection.
