Implement 'final' assignments. A variable cannot be assigned a new value after the final assignment. The syntax of the final assignment is <variable> =$=<value> or for the rule-specific variables it is <target>: <variable> =$=<value> The effect is identical to having .KATI_READONLY := <variable> or <target>: .KATI_READONLY := variable that follows the assignment statement. NOTE that if you still want to use `make`, please avoid having whitespace after `=$=` (otherwise this whitespace will become part of the variable's value). Also, the change rearranges rule parsing and evaluation code.

kati
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.
How to use for Android
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.
How to use for Android (deprecated way)
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.
More usage examples (deprecated way)
"make clean"
% ./ninja.sh -t clean
Note ./ninja.sh passes all parameters to ninja.
Build a specific target
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
