/* The `/proc' interface divides the target machine's register set up
|
|
into two different sets, the general purpose register set (gregset)
|
|
and the floating-point register set (fpregset). For each set,
|
|
there is an ioctl to get the current register set and another ioctl
|
|
to set the current values.
|
|
|
|
The actual structure passed through the ioctl interface is, of
|
|
course, naturally machine dependent, and is different for each set
|
|
of registers. For the i386 for example, the general-purpose
|
|
register set is typically defined by:
|
|
|
|
typedef int gregset_t[19]; (in <sys/regset.h>)
|
|
|
|
#define GS 0 (in <sys/reg.h>)
|
|
#define FS 1
|
|
...
|
|
#define UESP 17
|
|
#define SS 18
|
|
|
|
and the floating-point set by:
|
|
|
|
typedef struct fpregset {
|
|
union {
|
|
struct fpchip_state // fp extension state //
|
|
{
|
|
int state[27]; // 287/387 saved state //
|
|
int status; // status word saved at //
|
|
// exception //
|
|
} fpchip_state;
|
|
struct fp_emul_space // for emulators //
|
|
{
|
|
char fp_emul[246];
|
|
char fp_epad[2];
|
|
} fp_emul_space;
|
|
int f_fpregs[62]; // union of the above //
|
|
} fp_reg_set;
|
|
long f_wregs[33]; // saved weitek state //
|
|
} fpregset_t;
|
|
|
|
Incidentally fpchip_state contains the FPU state in the same format
|
|
as used by the "fsave" instruction, and that's the only thing we
|
|
support here. I don't know how the emulator stores it state. The
|
|
Weitek stuff definitely isn't supported.
|
|
|
|
The routines defined here, provide the packing and unpacking of
|
|
gregset_t and fpregset_t formatted data. */
