Var and Value classes cleanup and memory footprint reduction.

* Reduce Var instance size by moving the diagnostic message string to a
hash map for the instances that really have it (there are actually very
few such instances).
* Move common members from Var subclasses to the base class and
represent them more compactly.
* Remove RuleVar wrapper class, it is an extra object per rule-specific
variable.
* Rename Expr class to ValueList.
* Use additional constructors and convenience factory methods in Value
and its subclasses to avoid creating ValueList with a single element and
then compacting it.
* Use method overloading instead of having NewExpr2/NewExpr3, move them
for the global namespace to be factory methods of the Value class.

kati

Build Status

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
