[Qemu-devel] [PATCH v2 1/8] target-i386: x87 exception pointers using TC


From: Jaume Marti Farriol
Subject: [Qemu-devel] [PATCH v2 1/8] target-i386: x87 exception pointers using TCG.
Date: Thu, 28 Aug 2014 22:44:33 +0200

Hello,

In this patch I just add new fields in the CPUX86State struct to store the 
exception pointers.
Also I remove unnecessary parameters from cpu_x86_fsave and cpu_x86_frstor 
helpers.

Best regards,
Jaume
