This modifies the helpers for instructions fstenv/fnstenv, fsave,
fxsave, fldenv, frstor and fxrstor, to store to memory and restore from
memory the x87 exception pointers.
Also it add logic that efficiently stores the values of the exception
pointers, to be used in the instructions mentioned above
This adds tests for the x87 exception pointers.

This adds new fields in the CPUX86State struct to store the x87
exception pointers.
Also it adds a new enum type that encodes the operand size and the
processor operating mode (protected and real mode).
The patch also adds a new option (tcg-exception-pointers) in the

Hello,
This patch contains the main changes. It contains modifcations to the
target-i386/translate.c file.
Those modifications are meant to generate TCG instructions to maintain the
correct value for the variables fpop, fpip, fpdp, fpds and fpcs in the cpu
state.
Best regards,

Hello,
This patch includes changes in the helper parameters, for the instructions
involved in saving to memory and restoring the x87 exception pointers.
The changes are to include a new parameter to indicate if the processor is
running in protected more.

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
