-Warn about functions which might be candidates for attributes
-@code{pure} or @code{const}. The compiler only warns for functions
-visible in other compilation units or if it cannot prove that the
-function returns normally. A function returns normally if it doesn't
-contain an infinite loop nor returns abnormally by throwing, calling
-@code{abort()} or trapping. This analysis requires option
-@option{-fipa-pure-const}, which is enabled by default at @option{-O}
-and higher. Higher optimization levels improve the accuracy of the
-analysis.
