From 448d4d146b788898d56131d21001542f39681c9b Mon Sep 17 00:00:00 2001 From: Alex Bennée Date: Mon, 16 Mar 2020 17:21:42 +0000 Subject: target/arm: prepare for multiple dynamic XMLs We will want to generate similar dynamic XML for gdbstub support of SVE registers (the upstream doesn't use XML). To that end lightly rename a few things to make the distinction.
