Summary: In order to get the bots running quicker I would like to be able to use ccache with the test suite. This patch adds support for running the test suite using ccache. To use ccache pass `--param=use_ccache=true` when running the test suite. ccache will not cache any command that invokes ld, so the build step needs to be split into two separate compile commands. The cost of splitting the build step into two parts when not using ccache seems to be minimal. On my machine I saw a difference of ~5 seconds on a 5 minute test suite run. A full test suite run with ccache generates about 250MB of cached data. I recorded the following times for running the test suite in the following configurations: - no ccache: 340s - initial ccache run: 380s - rerun with ccache (no changes): 53s. - rerun with ccache (<string> changed): 80s - rerun with ccache (<cmath> changed): 169s - rerun with ccache (<valarray> changed): 69s Reviewers: mclow.lists, jroelofs, danalbert Reviewed By: jroelofs Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D6647 llvm-svn: 224603 |
