Hi,
The CONFIG_USER_ONLY definition allows limiting user-mode
code to user emulation (in contrast to system emulation).
We often use it in common code.
Often the negative form (to *exclude* user-mode) is used.
This works fine with system emulation in mind, but it could
introduce subtle bugs when neither user nor system emulation
are used, for example with tools.
There is a CONFIG_TOOLS definition, but it is not used in C:
config-host.mak:CONFIG_TOOLS=y
config-host.h:#define CONFIG_TOOLS 1
Not sure how to clarify / improve, this is a bit confusing.
Just thinking loudly :)
Regards,
Phil.
