Heya gang,
I apologize for keep going on about this but I still don't quite
understand why a seperate struct is needed for i386_fp_regs. Here is
what gnumachs looks like:
struct i386_fp_save {
unsigned short fp_control; /* control */
unsigned short fp_unused_1;
unsigned short fp_status; /* status */
unsigned short fp_unused_2;
unsigned short fp_tag; /* register tags */
unsigned short fp_unused_3;
unsigned int fp_eip; /* eip at failed instruction */
unsigned short fp_cs; /* cs at failed instruction */
unsigned short fp_opcode; /* opcode of failed instruction */
unsigned int fp_dp; /* data address */
unsigned short fp_ds; /* data segment */
unsigned short fp_unused_4;
};
struct i386_fp_regs {
unsigned short fp_reg_word[5][8];
/* space for 8 80-bit FP
registers */
};
And here is how Linux does it:
struct i387_fsave_struct {
long cwd;
long swd;
long twd;
long fip;
long fcs;
long foo;
long fos;
long st_space[20]; /* 8*10 bytes for each FP-reg = 80 bytes */
long status; /* software status information */
};
Is there some reason that I am not understand that i386_fp_regs has to
be a seperate struct and not an element of i386_fp_save?
Thanks and sorry to keep griping on this,
Barry deFreese (aka bddebian)
