From ad4ec2798fd7066bc9d879dcbdeae96073ad370f Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Wed, 13 Sep 2023 14:46:17 -0700 Subject: [PATCH] qom: Propagate alignment through type system MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Propagate alignment just like size. This is required in order to get the correct alignment on most cpu subclasses where the size and alignment is only specified for the base cpu type.
