From 3b14e2ffdd8eb4b7f7f4508768b75f2acc399370 Mon Sep 17 00:00:00 2001 From: Erik Verbruggen Date: Fri, 9 Sep 2016 15:37:57 +0200 Subject: QML: Make Heap::Object and all subclasses trivial GCC6 might dead-store-eliminate out our secret write to Base::mmdata, because it expects all memory content to be "undefined" before constructor calls. Clang might take the same approach if the constructor of Heap::Object is removed. By making these structs trivial, it also makes them memcpy-able.
