# This is a simpler version of allnoconfig.py, corresponding to how the C
# implementation does it. Setting a user value that's not in the assignable
# range of the symbol (between get_lower_bound() and get_upper_bound(), or,
# equivalently, not in get_assignable_values()) is OK; the value will simply
# get truncated downwards or upwards as determined by the visibility and
# selects.

# This version is a bit slower compared allnoconfig.py since Kconfiglib
# invalidates all dependent symbols for each set_value() call. This does not
# happen for load_config(), which instead invalidates all symbols once after
# the configuration has been loaded. This is OK for load_config() since nearly
# all symbols will tend to be affected anyway.
