Add platform-wide sampling PGO option Test: build Bug: 79161490 Bug: 153039105 Change-Id: Ibd30fffa0a97ca76155891f3aec8d7891226b9f1 Merged-In: Ibd30fffa0a97ca76155891f3aec8d7891226b9f1 (cherry picked from commit bcbcd65a99f8a40ffebac9494db5aa60c9dfff5e)
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For an outdated reference on Android.mk files, see build-system.html.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.
