This behavior of "stealing" values from parent makefiles is needed to match make. We already had similar behavior for list variables via the __move_items function, but were missing it for single value variables. Test: ./out/rbcrun -mode rbc ./build/make/tests/run.rbc Change-Id: Ib320b9b1cce0224184f585c7a391be1b5353b440
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For an outdated reference on Android.mk files, see build-system.html.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.
