From 04a37d4ca4bfef595b2e9bec99eac8bfc806c76b Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Thu, 29 Oct 2020 12:30:01 -0700 Subject: tcg: Make tb arg to synchronize_from_tb const MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is nothing within the translators that ought to be changing the TranslationBlock data, so make it const. This does not actually use the read-only copy of the data structure that exists within the rx region.
