From 700549620b3ee15924f19b9eb79961655ce671c5 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Thu, 24 Aug 2017 18:31:28 +0200 Subject: [PATCH] sparc: move adhoc CPUSPARCState initialization to realize time MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit SPARCCPU::env was initialized from previously set properties (with help of sparc_cpu_parse_features) in cpu_sparc_register(). However there is not reason to keep it there as this task is typically done at realize time. So move post properties initialization into sparc_cpu_realizefn, which brings cpu_sparc_init() closer to cpu_generic_init().
