platform_external_elfutils/libcpu, branch master Unnamed repository; edit this file 'description' to name the repository. Add build description for libdw 2020-09-18T21:00:53+00:00 Matthias Maennich maennich@google.com 2020-06-23T09:05:49+00:00 a55c49f0c016a1439f698f48d0cd8d328e4ae398 This adds build description for more elfutils libraries in order support users that require libdw, such as pahole and libabigail. While the remaining libraries could be considered standalone, they are not really suitable to be built standalone in soong as they have circular dependencies and are usually anyway built as one unit. Hence only build libdw and include all libraries into it. This then works as an extension for libelf. The generated files in libcpu are now all generated from sources. No really significant generated file is now checked in. Left are config.h and version.h, which are generated at update time via post_update.sh. The build rules for the generated files have been reverse engineered from the autotools build. This mostly making m4, bison and flex work what we want them to, but builtin rules in soong made that possible without being overly verbose. An additional library - libeu - needed to be added as a generator dependency. In order to not overload the main Android.bp with all the little generator details, subpackages have been reintroduced and visibility adjusted accordingly.
