Any comments?
It's really a bug and can cause the qemu to segmentfault.
Thanks,

Hi Philippe,
could this not be controlled by meson at this stage?
On X86, I register the tcg-specific types in tcg/*

Add a job to build QEMU on Aarch64 with TCG disabled, so
this configuration won't bitrot over time.
We explicitly modify default-configs/aarch64-softmmu.mak to
only select the 'virt' and 'SBSA-REF' machines.

We can now safely turn all TCG dependent build off when CONFIG_TCG is
off. This allows building ARM binaries with --disable-tcg.

Modules are registered early with type_register_static().
We would like to call tcg_enabled() when registering QOM types,
but tcg_enabled() returns tcg_allowed which is a runtime property

Hi,
This series add a Kconfig file to each target, allowing
to select target-specific features there, instead of from
the hardware Kconfig.
This simplifies managing multi-arch features such semihosting.
