Subject: Re: MMX and floating point insn suport for reversible debugging

Hi Hui,

dont we need to save FPU flags also, while saving floating point registers?

for e.g. instruction
FMUL/FMULP/FIMUL—Multiply ; aafter the result,
FPU flags may get affected 
as follows.

FPU Flags Affected
C1 Set to 0 if stack underflow occurred.
Set if result was rounded up; cleared otherwise.
C0, C2, C3 Undefined.

what is you opinion ?

Regards,
Oza.
