This commit improves the warning messages of the recursive dependency. Currently, sym->dir_dep.expr is not checked. Hence, any dependency in property visibility is regarded as the dependency of the symbol. [Test Code 1] config A bool "a" depends on B config B bool "b" depends on A [Test Code 2] config A bool "a" if B config B bool "b" depends on A For both cases above, the same message is displayed: symbol B depends on A symbol A depends on B This commit changes the message for the latter case like this: symbol B depends on A symbol A prompt is visible depending on B Also, 'select' and 'imply' are distinguished.
