Attachments: | Hello. i need to enumerate all module variables of the given types (it's easy, this is not the question) and make list of only __gshared ones. of course, i'm talking about CTFE. is there any hack/trick to determine if variable is __gshared? or if it is a thread-local, for that matter? i added 'isGShared' trait to my compiler, but i'm not expecting from others to do the same. ;-) the only hack i invented is this abomination: int v0; __gshared int v1; enum isGShared(alias var) = !__traits(compiles, mixin("{auto a___ = function typeof("~var.stringof~ ") () @safe { return "~var.stringof~"; };}")); pragma(msg, isGShared!v0); // false pragma(msg, isGShared!v1); // true sure, it's very limited, and we must do alot of checks before using it. it *SEEMS* to work, but i not tested it very well. |

There is the -vtls compiler switch.
