Hi,

please review the initial build support for JEP 230: Microbenchmark Suite[1]. Webrev: http://cr.openjdk.java.net/~redestad/8061281/jdk.00/ The build changes look good. (But I can't really review them as I wrote most of them :-))

As you say, we also need to update documentation, especially doc/testing.md, with the new micro test suite for run-test.

Bug: https://bugs.openjdk.java.net/browse/JDK-8061281

There are some added steps to be able to build the microbenchmark suite: export JMHHOME=/path/to/jmh (mkdir -p JMHHOME;cdJMHHOME; cd JMHHOME;cdJMHHOME; bash make/devkit/createJMHBundle.sh; tar -zxvf jmh-1.21.tar.gz) bash configure --with-jmh=$JMHHOME make build-microbenchmark This produces the JMH benchmarks under build/$CONFNAME/images/test/micro/microbenchmarks.jar There is also support woven into the make run-test target (thanks to Magnus), allowing for integrated build and test: make run-test TEST="micro:java.lang.reflect" MICRO="OPTIONS=-f 1 -wi 2;RESULTFORMAT=json" Remaining tasks before the JEP can be targetted is to write proper documentation and deciding which microbenchmarks to migrate from jmh-jdk-microbenchmarks[2]. Thanks! /Claes [1] http://openjdk.java.net/jeps/230 [2] http://openjdk.java.net/projects/code-tools/jmh-jdk-microbenchmarks/
