Remove empty rules for check_elf_files.timestamp If we don't have any new dependencies, or we never set up the check_elf_files.timestamp rule, don't create an empty one now. There were >7000 of these unused and empty rules in my AOSP aosp_cf_x86_phone build. This was initially brought to my attention by the new checks in https://github.com/google/kati/pull/189 Test: diff out/build-aosp_cf_x86_phone.ninja, only removed phony rules Change-Id: Ia43cbbd04df4a01d2182b14e3ccbe5d5ecbcabad
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For an outdated reference on Android.mk files, see build-system.html.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.
