From fa15162700a18ff243de46954bb613988c199ce7 Mon Sep 17 00:00:00 2001 From: Erik Verbruggen Date: Tue, 24 Jan 2017 17:06:03 +0100 Subject: Fix QString comparison on Aarch64 There was an off-by-one error in the while loop for aarch64: we start counting at 0 for the first position, so the last valid input position is "a+7", not 8. This wasn't covered by the tests, nor was the SSE2 version, so now there are also tests for both versions.
