Subject: help required : floating point for i386

Hi,

I am working on i386-tdep.c for floating point.

I try to do ;
record_arch_list_add_reg (ir.regcache,I386_ST0_REGNUM); does not deterministically record st0 register 
(sometims it records st1 or sometimes st7)
why is it so ?

we collect fpx registers in following functions. do we need to do something about following function, so it returns correct register !!
i387_supply_fxsave (regcache, -1, fpxregsetp);

please help.

Regards,
Oza.
