From 703a548aa9f148186ed8647092e8645e5a85f373 Mon Sep 17 00:00:00 2001 From: Sergio Lopez Date: Mon, 30 Sep 2019 17:26:29 +0200 Subject: [PATCH] hw/i386: make x86.c independent from PCMachineState MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As a last step into splitting PCMachineState and deriving X86MachineState from it, make the functions previously extracted from pc.c to x86.c independent from PCMachineState, using X86MachineState instead.
