From bc2eca9a682881f9da3cc7e2d75b752e549a134d Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Fri, 9 Nov 2018 04:26:39 +0100 Subject: ARM: 8811/1: always list both ldrd/strd registers explicitly The ldrd and strd instructions work on a pair of consecutive registers. It is possible to specify either the first register in the pair, or both registers explicitly. Let's always do the later to make things clearer.
