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

[Jaume Marti Farriol <jaume.martif@gmail.com>]

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
