Well interestingly enough a test just now showed the accessor functions
being inlined, thus the DECLAIM worked. The file needed to already
have been compiled and loaded once before recompilation uses the
declamations (which has been fixed by using an EVAL-WHEN).
Interestingly, the second SETF doesn't get inlined, but the first, and
the last two read accesses are (neat). I initially thought it could be
something to do with the SETF optimizer not going deep enough, but it's
still the case using two SETF.
(defun print-timeval-2 ()
(declare (optimize (speed 3) (safety 0) (debug 0)))
(let ((tv (make-timeval)))
(setf (timeval-sec tv) 1)
(setf (timeval-usec tv) 2)
(format t "~A, ~A~%" (timeval-sec tv) (timeval-usec tv))))
/* function definition for PRINT-TIMEVAL-2 */
/* optimize speed 3, debug 0, space 0, safety 0 */
static cl_object L25print_timeval_2()
{ VT26 VLEX26 CLSR26 STCK26
const cl_env_ptr cl_env_copy = ecl_process_env();
cl_object value0;
TTL:
{cl_object V1; /* TV */
V1= ecl_make_pointer(GC_MALLOC(sizeof(struct timeval)));
(((struct timeval *)ecl_to_pointer(V1))->tv_sec = (ecl_int64_t)(1));
L20_setf_timeval_usec_(ecl_make_fixnum(2),V1) /* (SETF TIMEVAL-USEC)
*/;
{long V2;
V2= (long)((((struct timeval *)ecl_to_pointer(V1))->tv_sec));
{long V3;
V3= (long)((((struct timeval *)ecl_to_pointer(V1))->tv_usec));
value0=cl_format(4,ECL_T,VV[139],ecl_make_long(V2),ecl_make_long(V3))
/* FORMAT */;
return value0;}}
}
}
