+/* "get" is called repeatedly until it ticks over, just in case on a fast

+
+ speed_cyclecounter is called on the same side of the "get" for the start

+ sample to the cycles sample, since that period will cancel out in the

+
+ 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.

+
+ 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. */
