It is now no longer needed to have a ty::ctxt to get at the contents of a ty::t. The straight-forward approach of doing this, simply making ty::t a box type, unfortunately killed our compiler performance (~15% slower) through refcounting cost. Thus, this patch now represents ty::t as an unsafe pointer, assuming that the ty::ctxt, which holds these boxes alive, outlives any uses of the ty::t values. In the current compiler this trivially holds, but it is does of course add a new potential pitfall. ty::get takes a ty::t and returns a boxed representation of the type. I've changed calls to ty::struct(X) to do ty::get(X).struct. Type structs are full of vectors, and copying them every time we wanted to access them was a bit of a cost. |
