Merge remote-tracking branch 'aosp/upstream' * aosp/upstream: Fix 32-bit builds; only build 64-bit in Android trees Collect stats about how long it takes to process included makefiles When printing top stats, include count Stop using TLS for stats start time Test: treehugger Change-Id: I1a464d7d265e73d66bdf93069cc3008a19beb11d
kati is an experimental GNU make clone. The main goal of this tool is to speed-up incremental build of Android.
Currently, kati does not offer a faster build by itself. It instead converts your Makefile to a ninja file.
For Android-N+, ckati and ninja is used automatically. There is a prebuilt checked in under prebuilts/build-tools that is used.
All Android's build commands (m, mmm, mmma, etc.) should just work.
Set up kati:
% cd ~/src % git clone https://github.com/google/kati % cd kati % make
Build Android:
% cd <android-directory> % source build/envsetup.sh % lunch <your-choice> % ~/src/kati/m2n --kati_stats % ./ninja.sh
You need ninja in your $PATH.
% ./ninja.sh -t clean
Note ./ninja.sh passes all parameters to ninja.
For example, the following is equivalent to “make cts”:
% ./ninja.sh cts
Or, if you know the path you want, you can do:
% ./ninja.sh out/host/linux-x86/bin/adb
