Posted in reply to Andrej Mitrovic | http://d.puremagic.com/issues/show_bug.cgi?id=7719 --- Comment #1 from Andrej Mitrovic <andrej.mitrovich@gmail.com> 2012-03-16 17:13:03 PDT --- There are more issues with these enums inside of brackets. Right now I'm having the weirdest errors where referencing these enums doesn't work from a class defined below it: enum { wxUSER_ATTENTION_INFO = 1, wxUSER_ATTENTION_ERROR = 2, } If they're each defined separately: enum wxUSER_ATTENTION_INFO = 1; enum wxUSER_ATTENTION_ERROR = 2; then it works. I don't have a minimal test-case for this now (working on it), but there's obviously some issues with the implementation. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |

Posted in reply to Andrej Mitrovic | http://d.puremagic.com/issues/show_bug.cgi?id=7719 --- Comment #2 from Andrej Mitrovic <andrej.mitrovich@gmail.com> 2012-10-04 08:25:05 PDT --- I've found some lead: in enum.c: void EnumDeclaration::semantic0(Scope *sc) { /* This function is a hack to get around a significant problem. * The members of anonymous enums, like: * enum { A, B, C } * don't get installed into the symbol table until after they are * semantically analyzed, yet they're supposed to go into the enclosing * scope's table. Hence, when forward referenced, they come out as * 'undefined'. The real fix is to add them in at addSymbol() time. * But to get code to compile, we'll just do this quick hack at the moment * to compile it if it doesn't depend on anything else. */ if (isdone || !scope) return; if (!isAnonymous() || memtype) return; for (size_t i = 0; i < members->dim; i++) { EnumMember *em = (*members)[i]->isEnumMember(); if (em && (em->type || em->value)) return; } // Can do it semantic(sc); } If I remove the for loop and let semantic do its work the OP code compiles. But I don't know the extent of this hack that's in place now, whether it's still necessary or not. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
