When a class is deleted, the user-defined destructor is not invoked.

[sybs5968]

Hello, I have a problem when I try to use your open source project. Here is the source for testing.

class SimStream {
public:
    int n;
    double a;
    char b;
    SimStream() {
        n = 0;
    }
    SimStream(double _a) {
        a = _a;
    }
    SimStream(int _n , double _a){
        n = _n; a = _a;
    }
    ~SimStream() { printf("---------------------------------------1\n"); };
};

void doSomeThing(SimStream *t) {};

int main() {
    SimStream *s = new SimStream;
    doSomeThing(s);
    delete s;
    return 0;
}

It seems that custom destructor not called. When I delete a class,there are only memref.dealloc %alloc : memref<1x!llvm.struct<(i32, f64, i8)>> and not anything about user-defined destructor function. I don't know what the problem is. If you can answer it, I'd appreciate it.

We currently have not support destructors in Polygeist

ok,thank you very much.

[sybs5968]

And Where can I see which cases are supported by the current project?
