llvm dev - Sep 2013 - [LLVMdev] Error on completing ToyThread::execute() in ToyVM (vmkit project)

-- 
Hi all,

My code is:
    TOY_VAR(Picture*, aPic);    
    aPic = Picture::doNew(-2, 1, -1, 1, 1900, 1200);

This code has the following compilation error:
../lib/ToyRoot.h:41:33: error: no member named 'getVirtualTable' in
'Toy::Picture'
                        res = gc::operator new(sz, o.getVirtualTable());
                                                   ~ ^
Is it correct?

Best regards,
Mkh

Hi,

The VMKit framework has been updated to be more generic.
The getVirtualTable method is not exposed anymore since this method suppose
that your object layout contains a virtual table.
Now you have new methods to get / set objects type which are virtual methods
inherited by the vmkit::VirtualMachine class.

Thus you can still keep your object identity as virtual tables, but now the
getVirtualTable is a static method provided by the VirtualTable class.

Hi all,

I changed the the operator new method of ToyRoot class as follows:

template <class T>
void* operator new(size_t sz, int param=0) {
    void* res = 0;
    llvm_gcroot(res, 0);
    static T o;
    VirtualTable *tmp;
 
tmp=const_cast<VirtualTable*>(VirtualTable::getVirtualTable((gc*)&o));
    res = gc::operator new(sz, tmp);
    return res;
}

By running the "static T o" the following message printed:

toyVM: ../lib/ToyRoot.h:31: Toy::ToyRoot::ToyRoot(): Assertion `false'
failed.


Best regards,
Mkh
