This includes changing the iteration\n code to use the actual total time calculated by the benchmark as a basis\n for determining whether there are enough iterations instead of using\n the time it takes to run the benchmark.\n- Allow benchmarks to take no argument, int, or double.\n- Fix the PrettyInt printer for negative integers.\n- Modify the max column width name to include the whole name including\n the arg part.\n- Reformat property_benchmark.cpp in line with the rest of the code.\n- Modify a few of the math benchmarks to take an argument instead of\n separate benchmarks for the same function with different args.\n- Create a vector of regex_t structs to represent the args all at\n once instead of when running each benchmark.\n\nThis change is in preparation for adding new math based benchmarks.\n\nTested by running on a nexus flo running at max using the new code\nand the old code and comparing. All of the numbers are similar, but\nsome of the iterations are different due to the slightly different\nalgorithm used.\n\nChange-Id: I57ad1f3ff083282b9ffeb72e687cab369ce3523a\n" }, { "commit": "8c4994bbc1a9a01e34ea92c91eb5b2d1a27bd074", "tree": "8b632cea0832373b9cb843427bb5976b3668f1a2", "parents": [ "f374358414812d3e5a45ba75a2b1926693924420" ], "author": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Tue Jan 20 18:09:05 2015 -0800" }, "committer": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Wed Jan 21 10:33:30 2015 -0800" }, "message": "Implement __fsetlocking.\n\nThe old __isthreaded hack was never very useful on Android because all user\ncode runs in a VM where there are lots of threads running.
