Support aconfig dump --dedup Add a flag to aconfig dump that will allow identical flags to be merged without erroring. This will allow merging the aconfig cache files from dependencies for each module, which requires passing less data to Make from Soong, and thus reduces the percentage of builds require Kati analysis. Bug: 313698230 Test: aconfig.test Change-Id: Id2d9b78225720ce01defad4b13ea9395f6ab1033
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For an outdated reference on Android.mk files, see build-system.html.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.
