/* machine-dependent cycle counters code. Needs to be inlined. */
/***************************************************************************/
/* To use the cycle counters in your code, simply #include "cycle.h" (this
file), and then use the functions/macros:
ticks getticks(void);
ticks is an opaque typedef defined below, representing the current time.
You extract the elapsed time between two calls to gettick() via:
double elapsed(ticks t1, ticks t0);
which returns a double-precision variable in arbitrary units. You
are not expected to convert this into human units like seconds; it
is intended only for *comparisons* of time intervals.
(In order to use some of the OS-dependent timer routines like
Solaris' gethrtime, you need to paste the autoconf snippet below
into your configure.ac file and #include "config.h" before cycle.h,
or define the relevant macros manually if you are not using autoconf.)
*/

defined according to whether the corresponding function/type/header
