Bug ID 162 Summary GDC unable to de-virtualise method calls Product GDC Version development Hardware All OS All Status NEW Severity enhancement Priority Normal Component gdc Assignee ibuclaw@gdcproject.org Reporter ibuclaw@gdcproject.org
Currently we emit method calls as the following: *(c->__vptr + 40) (c, 1, 2, 3); Which translate directly into the following trees: indirect_ref(pointer_plus(component_ref(c, __vptr), 40)) GCC provides a more simplistic tree code called obj_type_ref, which represents a virtual method lookup, and given the binfo structure we already pass to the backed, this would give a chance for the optimiser passes to statically determine the dynamic type of the object and devirtualise the call. obj_type_ref(component_ref(c, __vptr), c, 40)
