Clean up Symbol handling. * Introduce SymbolSet class. As each Symbol contains sequentially assigned ordinal value, representing a set of Symbols as a growable bitset is faster and more space-efficient than generic unordered_bitmap (for the full build, we save about 1500MB). * Remove useless constructor argument. * Make a Symbol for .KATI_READONLY constant instead of Evaluator member. * Avoid testing 'this' for nullness in Value::DebugString, it's not standard-compliant. Make Value::DebugString static instead. * Avoid 'fallthrough' compiler warning.
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.
Now AOSP has kati and ninja, so all you have to do is
% export USE_NINJA=true
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 # Use --goma if you are a Googler. % ./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
