Not setting TARGET_ARCH is ok if TARGET_ARCH_SUITE is set instead. Skip certain TARGET_ARCH-specific steps of the config: - don't run the 'select' steps to figure out cpu flags - don't generate dexopt config for TARGET_ARCH Bug: 174315599 Test: lunch <product that sets TARGET_ARCH_SUITE but not TARGET_ARCH> Change-Id: I74a9e71d0cc5c7f74d3b10b1c8bb89682c096d7c
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For an outdated reference on Android.mk files, see build-system.html.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.
