From dcfb1d0476559cabe45ffbfb1d7667909ab309c2 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 4 Feb 2022 16:55:01 +0000 Subject: target/arm: Move '-cpu host' code to cpu64.c MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Now that KVM has dropped AArch32 host support, the 'host' CPU type is always AArch64, and we can move it to cpu64.c. This move will allow us to share code between it and '-cpu max', which should behave the same as '-cpu host' when using KVM or HVF.
