Switch platform-NDK unwinder to LLVM libunwind.a prebuilt Link against the libunwind.a shipped with the NDK so it matches what's linked into the NDK's libc++_shared.so. For arm32, binary.mk and cxx_stl_setup.mk had been adding two different versions of the LLVM unwinder to the same linker command-line. Remove the duplicate one from cxx_stl_setup.mk. -Wl,--exclude-libs is now unnecessary because the symbols are marked hidden in the archive itself. Bug: http://b/153025717 Test: device boots, manually inspect some linker command lines Change-Id: Ie7182bd565014348b16448976dc6587d2885ba99
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For an outdated reference on Android.mk files, see build-system.html.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.
