* Use Config/DeviceConfig functions to access ProductVariablesDan Willemsen2018-04-171-6/+2
| | | | | | | | | | | | An upcoming change will stop exporting ProductVariables from Config, so switch to using existing accessor functions, and add more when they're missing.

* Allow platform modules to link to vendor public librariesJiyong Park2018-03-301-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, when building with VNDK, platform modules are not allowed to link against vendor libraries, because the ABI of the vendor libraries are not guaranteed to be stable and may differ across multiple vendor images. However, the vendor public libraries are the exceptions. Vendor public libraries are vendor libraries that are exposed to 3rd party apps and listed in /vendor/etc/public.libraries.txt. Since they are intended to be exposed to public, their ABI stability is guaranteed (by definition, though it is up to the vendor to actually guarantee it). This change provides a way to make a vendor lib as public by defining a module of type 'vendor_public_library' with a map file that enumerates public symbols that are publicized: cc_library { name: "libvendor", proprietary: true, ... } vendor_public_library { name: "libvendor", symbol_file: "libvendor.map.txt", } This defines a stub library module named libvendor.vendorpublic from the map file. `shared_libs: ["libvendor"]` is redirected to the stub library when it is from the outside of the vendor partition.

* vendor_available:false hides a lib from vendorsJiyong Park2017-10-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | When a lib is explicitly marked as `vendor_available: false`, then it can't be directly depended by a vendor lib which is installed to /vendor partition. This is to hide some VNDK libs (including llndk) from vendors so that platform owners can have a freedom of modifying their ABI without breaking vendors. In addition, the list of the private libs are exported to the make world as VNDK_PRIVATE_LIBRARIES. Also, fixed a bug that allowed a vndk lib to link against to vendor library (or vendor variant of a system lib) if the lib is prebuilt. Bug: 64730695 Bug: 64994918 Test: Add `vendor_available: false` to libft2 and libcompiler_rt. Add the libs to shared_libs property of a vendor library in soong (i.e. libnbaio_mono).

* Move default libnativehelper include to mock dir.Steven Moreland2017-07-181-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also export the corresponding variable to make. libnativehelper's include_deprecated contains all of the headers that are currently used by libraries without the "nativehelper/" prefix.

* Add integer_overflow sanitization build option.Ivan Lozano2017-07-071-0/+2
| | | | | | | | | | | | | | | | | | | | Adds the SANITIZE_TARGET=integer_overflow build option to apply signed and unsigned integer overflow sanitization globally. This implements the Soong side of the build option. An additional build option is provided to control whether or not to run in diagnostics mode, controlled by SANITIZE_TARGET_DIAG. This works the same way that SANITIZE_TARGET does and currently only supports 'integer_overflow' as an option. A default sanitizer blacklist is added to avoid applying sanitization to functions that are likely to exhibit benign overflows. Bug: 30969751 Test: Building with and without the new flags, device boot-up, tested various permutations of controlling the new flags from build files.

* Black-list for clang LibTooling Cflags.Jayant Chowdhary2017-06-191-5/+5
| | | | | | | | | | | | Add a list of flags which are not understood by clang LibTooling tools and filter them out of the Cflags the tools are invoked with. Test: In frameworks/av, make libmedia vendor_available (this invokes header-abi-dumper on this module), mm -j64. Bug: 62447349 Change-Id: I46f017212b89f4331145c999103d0ed44da0abaf
* Optimizations to abi checking.Jayant Chowdhary2017-05-251-0/+1
| | | | | | | | | | | | | | | | | | | | | We now add export_static_lib_headers, export_generated_headers to the filters while dumping the abi of a library using header-abi-dumper (through -I<dir> additions to the invocation of header-abi-dumper and header-abi-linker) Also add support for zipped reference source based abi dumps. Test: mm -j64 in hardware/interfaces/nfc/default/1.0 produces android.hardware.nfc@1.0.so.lsdump with abi filtered out using generated headers. Test: Copied the linked abi dumps produced by mm -j64 in bionic/libc to prebuilts/abi-dumps/ndk and gzipped them. Ran mm -j64 again in bionic/libc and verified header-abi-diff getting invoked.

* Split /system and /vendor modules, allow multi-installationDan Willemsen2017-04-111-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nothing changes if BOARD_VNDK_VERSION isn't set. When the VNDK is enabled (BOARD_VNDK_VERSION in Make), this will split /system and /vendor modules into two different variant spaces that can't link to each other. There are a few interfaces between the two variant spaces: The `llndk_library` stubs will be available in the /vendor variant, but won't be installed, so at runtime the /system variant will be used. Setting `vendor_available: true` will split a module into both variants. The /system (or "core") variant will compile just like today. The /vendor ("vendor") variant will compile against everything else in the vendor space (so LL-NDK instead of libc/liblog/etc). There will be two copies of these libraries installed onto the final device. Since the available runtime interfaces for vendor modules may be reduced, and your dependencies may not expose their private interfaces, we allow the vendor variants to reduce their compilation set, and export a different set of headers: cc_library { name: "libfoo", srcs: ["common.cpp", "private_impl.cpp"], export_include_dirs: ["include"], target: { vendor: { export_include_dirs: ["include_vndk"], exclude_srcs: ["private_impl.cpp"], srcs: ["vendor_only.cpp"], }, }, } So the "core" variant would compile with both "common.cpp" and "private_impl.cpp", and export "include". The "vendor" variant would compile "common.cpp" and "vendor_only.cpp", and export "include_vndk".

* install *.so in different paths for their typesJiyong Park2017-03-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Shared libraries are now installed to different directories depending on their types. * NDK libraries: /system/lib/ndk * VNDK libraries: /system/lib/vndk * VNDK-ext libraries: /system/lib/vndk-ext * Framework-only libraries: /system/lib * Vendor-only libraries: /vendor/lib * Same-process HALs: /vendor/lib/sameprocess In addition, a new module type vndk_ext_library is added. It is almost identical to cc_shared_library but it introduces another attribute 'extends'. This is use to reference the vndk library that this vndk-ext library is extending. For example, in order to extend a vndk library libFoo: cc_library { name: "libFoo", srcs: [...] } --------------------- vndk_ext_library { name: "libFoo-extended", srcs: [...] extends: "libFoo" } Then, libFoo will be installed as /system/lib/vndk/libFoo.so and libFoo-extended will be installed as /system/lib/vndk-ext/libFoo.so. Note that file name of the latter is libFoo.so, not libFoo-extended.so: file name of an extending module is automatically set to that of the extended module. Bug: 33681361 Test: build & run.

Test: Migrated libc to this system and everything still builds. build.ninja shows libraries being built and used and headers are collected for the sysroot. Bug: http://b/27533932 Change-Id: Iaba00543c1390f432befe0eed768ed3fbb8a9b96
* Rename exported make variables for system headersColin Cross2016-07-201-1/+47
| | | | | | | | | Add SYSTEM_ to variables that contain headers that are used with -isystem, and split -I and -isystem variables into separate make variables. Also export SRC_HEADERS and SRC_SYSTEM_HEADERS to compare against make. Change-Id: I02097c35d1d5342ebce8311d8878fff33b118adb
* Support linking against NDK prebuilt librariesDan Willemsen2016-07-081-0/+1
| | | | | | | When sdk_version is specified, we need to use the prebuilt ndk versions of these libraries instead of the platform versions. Change-Id: I4ff33a234a985041ebe11ab148d64d0f8df66fc4
* Remove support for libstdc++ on Android/Linux/DarwinDan Willemsen2016-06-151-2/+0
| | | | | | | It's now only supported on Windows, where we don't have libc++ support yet. Change-Id: I64891b7558d3d2942588687017a0c2f695c18d5c
* Simplify arch target handlingColin Cross2016-06-021-35/+46
| | | | | | | | | | | | Soong's multi-architecture building has grown complex, with the combination of HostOrDevice+HostType+Arch necessary to determine how to build a variant of a module, and three separate mutators to split each into its variations. Combine HostOrDevice+HostType into Os, which will be Linux, Darwin, Windows, or Android. Store Os+Arch as a single Target. Change-Id: I92f2e2dac53617d595a35cc285d2bd348baa0fbd
