Also gcc will wrongly warn (and you can't turn off the warning, even in -Werror builds) if you use |enum Foo : T| as the type of a bit-field. See <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51242>. The JS_ENUM_HEADER/JS_ENUM_FOOTER uses in js/public/Value.h derive from this bug. Other than these two issues (one clear and easily observed, one that seems B2G-only), |enum Foo : T| is fair game to use. We have at least one fully unguarded use of this in js/src/vm/Shape.h for the js::Shape::SlotInfo enum, and the sky hasn't fallen yet. :-) Jeff _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
