I guess I misunderstand the problem, as given: const double ggPi = 3.14159265358979323846; double const divPi = 1 / ggPi; It would seem that neither ggPi or divPI should be designated "unchanging" at the tree/rtl level, as neither are global static const objects, although: 3.14159265358979323846 is, if stored as a value; as opposed to being inlined in the code as an immediate. ggPi and divPi are simply variables which are initialized with values at runtime; where the fact that they're "const" has prevented an assignment (other than an initializing one) being accepted as valid during semantic analysis. Where post semantic analysis, they're just variables just like any others which happen to have no assignments specified post initialization (as enforced by the front end); so should not be marked READONLY/unchanging to begin with, it would seem? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20912
