From a0ee11510df847fee64274d260a6c5f693a70787 Mon Sep 17 00:00:00 2001 From: Kent Hansen Date: Mon, 2 Aug 2010 16:11:33 +0200 Subject: Add benchmarks for QMetaType::construct(int type, void *copy = 0) Tests all built-in (core and GUI) types, both default construction (copy == 0) and copy construction. The benchmarks for GUI types must go into a separate file because core tests don't (and shouldn't) link against QtGui.
