Hi Paolo,

currently we have use of CONFIG_TCG in tests/,

but is that variable available at all in there?

I have to adapt some qemu/tests/qtest/* to work also without tcg for ARM,

but I think I am not seeing CONFIG_TCG filtering through, and I wonder whether all the 
checks in there are actually "wrong".

Looking at meson.build it would seem to me that only stuff in target/ would be 
able to see CONFIG_TCG,
as a result of

foreach target : target_dirs
   config_target = config_target_mak[target]
   target_name = config_target['TARGET_NAME']
   arch = config_target['TARGET_BASE_ARCH']
   arch_srcs = [config_target_h[target]]
   arch_deps = []
   c_args = ['-DNEED_CPU_H',

But how could tests see this?

The test are generic, not target-specific code, so they can not see things like NEED_CPU_H, of course.

But CONFIG_TCG seems to be defined in config-host.h, so you should be able to use that define, shouldn't you?
