/* "get" is called repeatedly until it ticks over, just in case on a fast
processor it takes less than a microsecond, though this is probably
unlikely if it's a system call.
speed_cyclecounter is called on the same side of the "get" for the start
and end measurements. It doesn't matter how long it takes from the "get"
sample to the cycles sample, since that period will cancel out in the
difference calculation (assuming it's the same each time).
Letting the test run for more than a process time slice is probably only
going to reduce accuracy, especially for getrusage when the cycle counter
is real time, or for gettimeofday if the cycle counter is in fact process
time. Use CLK_TCK/2 as a reasonable stop.
It'd be desirable to be quite accurate here. The default speed_precision
for a cycle counter is 10000 cycles, so to mix that with getrusage or
gettimeofday the frequency should be at least that accurate. But running
measurements for 10000 microseconds (or more) is too long. Be satisfied
with just a half clock tick (5000 microseconds usually). */

/* The measuring routines use these big macros to save duplication for
similar forms. They also get used for some automatically generated
measuring of new implementations of functions.
Having something like SPEED_ROUTINE_BINARY_N as a subroutine accepting a
function pointer is considered undesirable since it's not the way a
normal application will be calling, and some processors might do
different things with an indirect call, like not branch predicting, or
doing a full pipe flush. At least some of the "functions" measured are
actually macros too.
The net effect is to bloat the object code, possibly in a big way, but
only what's being measured is being run, so that doesn't matter.
The loop forms don't try to cope with __GMP_ATTRIBUTE_PURE or
ATTRIBUTE_CONST on the called functions. Adding a cast to a non-pure
function pointer doesn't work in gcc 3.2. Using an actual non-pure
function pointer variable works, but stands a real risk of a
non-optimizing compiler generating unnecessary overheads in the call.
Currently the best idea is not to use those attributes for a timing
program build. __GMP_NO_ATTRIBUTE_CONST_PURE will tell gmp.h and
gmp-impl.h to omit them from routines there. */
