Siddhesh Poyarekar 96e6a7167e benchtests: Make bench-memcmp print json
The benchamrk result can now be studied using the compare_strings.py
script.

	* benchtests/bench-memcmp.c: Print json instead of plain text.

Siddhesh Poyarekar 3dfcbfa1a4 benchtests: Reallocate buffers for every test run
Keeping the buffers the same across test runs gives later invocations
the advantage since they access cached data.  Reallocate so that all
test runs are on equal grounds.

	* benchtests/bench-memcmp.c (do_test): Call realloc_buf for
	every test run.

Adhemerval Zanella b598e13477 Adjust benchtests to new support library.
This patch basically replaces the test-skeleton.c inclusion by
support/test-driver.c and also minor adjustments in bench-string.h.

Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

	* benchtests/bench-string.h (TEST_FUNCTION): Use name without
	parenthesis.
	(CMDLINE_PROCESS): Define using function instead of macro.
	* benchtests/bench-memccpy.c: Include <support/test-driver.c> instead
	of test-skeleton.

Will Newton 44558701ff benchtests: Switch string benchmarks to use bench-timing.h.
Switch the string benchmarks to using bench-timing.h instead
of hp-timing.h directly. This allows the string benchmarks to
be run usefully on architectures such as ARM that do not have
support for hp-timing.h.

In order to do this the tests have been changed from timing each
individual call and picking the lowest execution time recorded to
timing a number of calls and taking the mean execution time.

ChangeLog:

2013-09-04   Will Newton  <will.newton@linaro.org>

	* benchtests/bench-timing.h (TIMING_PRINT_MEAN): New macro.
	* benchtests/bench-string.h: Include bench-timing.h instead
	of including hp-timing.h directly. (INNER_LOOP_ITERS): New
	define. (HP_TIMING_BEST): Delete macro. (test_init): Remove
	call to HP_TIMING_DIFF_INIT.
	* benchtests/bench-memccpy.c: Use bench-timing.h macros
	instead of hp-timing.h macros.
