From f093c842e65b251e24ea3a2d6daaa91326a4f862 Mon Sep 17 00:00:00 2001 From: Matt Turner Date: Fri, 20 Nov 2015 21:18:26 -0800 Subject: i965: Use implicit backend_reg copy-constructor. In order to do this, we have to change the signature of the backend_reg(brw_reg) constructor to take a reference to a brw_reg in order to avoid unresolvable ambiguity about which constructor is actually being called in the other modifications in this patch. As far as I understand it, the rule in C++ is that if multiple constructors are available for parent classes, the one closest to you in the class heirarchy is closen, but if one of them didn't take a reference, that screws things up.
