Hi Hui,

please find my comments below.

Oza : insns like FFREE changes register like FTAG.
so we need to record it.
The patch concentrates on any insn which has potential to change any of the FPU environment registers and stack.

Oza: gdb already has support for i386 for those(fpu) registers.
command -> [info float/info all-registers]
give all floating point registers including whole x87 FPU environment.

Oza.
