From: Arnaldo Carvalho de Melo Date: Fri, 29 Jan 2016 17:49:31 +0000 (-0300) Subject: perf tools: Speed up build-tests by reducing the number of builds tested X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=a639a623904cc526cebd7679debf86e5c8e5590b;p=deliverable%2Flinux.git perf tools: Speed up build-tests by reducing the number of builds tested The 'tools/perf/test/make' makefile has in its default, 'all' target builds that will pollute the source code directory, i.e. that will not use O= variable. The 'build-test' should be run as often as possible, preferrably after each non strictly non-code commit, so speed it up by selecting just the O= targets. Furthermore it tests both the Makefile.perf file, that is normally driven by the main Makefile, and the Makefile, reduce the time in half by having just MK=Makefile, the most usual, tested by 'build-test'. Please run: make -C tools/perf -f tests/make from time to time for testing also the in-place build tests.
