Sorry to resurrect an ancient commit, but I happened to be in the code working on attribute subjects. As best I can tell, gcc does not support this construct. I used the codegen test from this commit and got: http://ideone.com/2TxMtR http://goo.gl/EU1HT9 (gcc.godbolt.com) It seems that it emits a warning in gcc: 'weak' attribute does not apply to types. So the question becomes: should I continue to support weak on a class declaration with my refactoring, should this feature be removed from clang, or should there be a separate refactoring to note that this is a clang-specific extension? Thanks! ~Aaron _______________________________________________ cfe-commits mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
