Introduce a builder pattern for constructing a cache from flag declarations and flag values. Teach the builder to sort the flags by name as the last step. This will ensure consistent dump output regardless of the order flags are specified in the input files. Bug: 279485059 Test: atest aconfig.test Change-Id: Icdd62f51fa3761a469663f17581a83d9909e9ffe
Android Make Build System
This is the Makefile-based portion of the Android Build System.
For documentation on how to run a build, see Usage.txt
For a list of behavioral changes useful for Android.mk writers see Changes.md
For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.
This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
