Hello everyone, this is a proposal in the libtcg direction, i.e.,
enabling building a single QEMU executable featuring multiple *targets*
(i.e., TCG frontends).
This follows what we discussed in recent KVM calls and originally at
the KVM Forum Emulation BoF.
Note that our commitment to this

This issue is already handled by another similar patch (target/hexagon:
suppress unused variable warning) that will soon end up in a pull
request.
Thanks for looking into

So that would be an optimization if `HOST_LONG_BITS

`meson-buildoptions.sh-timestamp` would be
Note: `Makefile` relies on modification dates in the source tree to
detect changes to `meson_options.txt`. However, git does not track
those. Therefore, the following was necessary to regenerate
`meson-buildoptions.sh`:
touch meson_options.txt
cd "$BUILD_DIR"
make update-buildoptions
