From 5ee1e3cebc47495a36d17a0066c241978ca6f502 Mon Sep 17 00:00:00 2001 From: Siddhesh Poyarekar Date: Thu, 22 Jun 2017 23:44:19 +0530 Subject: benchtests: Make memcpy benchmarks print results in json Print the benchmark output for various memcpy benchmarks in json so that it can be predictably parsed and analyzed. * benchtests/bench-memcpy-large.c: Include json-lib.h. (do_one_test): Print json. (do_test): Likewise. (test_main): Likewise. * benchtests/bench-memcpy-random.c: Include json-lib.h. (do_one_test): Print json. (do_test): Likewise. (test_main): Likewise. * benchtests/bench-memcpy.c: Include json-lib.h. (do_one_test): Print json. (do_test): Likewise.
