Changes

  • Updated LLVM to clang-r547379. See clang_source_info.md in the toolchain
    directory for version information.
  • ndk-stack will now find symbols in files with matching build IDs even if the
    file names do not match.
  • ndk-stack will now find symbols in files with matching build IDs even if the
    name of the file is not present in the trace.
  • Issue 2078: ndk-stack now accepts a native-debug-symbols.zip file for the
    --sym argument as an alternative to a directory.

Announcements

  • The 16 KiB page size compatibility option that was added in r27 is now on by
    default. If necessary, you can still opt-out (see below).

Changes

  • Updated LLVM to clang-r530567c. See clang_source_info.md in the toolchain
    directory for version information.

    • Runtime libraries for non-Android have been removed reduce disk usage.
    • libc++ now includes debug info to aid debugging. This may make
      libc++_shared.so and any binaries that link libc++_static.a much larger
      before they are stripped. The Android Gradle Plugin will strip binaries when
      creating APKs, so this should not affect production apps.
    • Issue 2046: libclang and libclang-cpp are now supported.

  • PAGE_SIZE is no longer defined by default for arm64-v8a or x86_64. To
    re-enable, set APP_SUPPORT_FLEXIBLE_PAGE_SIZES (ndk-build) or
    ANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES (CMake) to false. See Support 16 KB
    page sizes     for more information.

  • The default alignment of shared libraries for arm64-v86 and x86_64 is now 16k.
    To revert to 4k alignment, set APP_SUPPORT_FLEXIBLE_PAGE_SIZES (ndk-build)
    or ANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES (CMake) to false. See Support 16 KB
    page sizes     for more information.

  • Issue 1307: Removed non-NDK binder headers. A number of binder headers that
    should have been shipped with aidl were mistakenly shipped in the NDK. These
    headers are tightly coupled to the version of aidl used, so this introduced an
    unwanted version restriction between build-tools and the NDK. If you are using
    the NDK aidl backend, you will need to pass the aidl include path when
    building. See the aidl backend docs for more information.

  • Issue 2058: Weak API references now work for libc APIs. This was enabled
    by conditionally removing the #if __ANDROID_API__ >= ... guards that
    previously wrapped declarations in libc headers when weak API references are
    used. When weak API references are not used (the default behavior), the
    declarations will still be hidden by the preprocessor.

    If your project contains polyfills for any of those APIs and uses weak API
    references    , this change may break your build due to the conflicting
    declarations. The simplest fix is to rename your polyfill to not collide with
    libc. For example, rename conflicting_api to conflicting_api_fallback and
    call that instead. Use #define conflicting_api() conflicting_api_fallback()
    if you want to avoid rewriting callsites.

    Please open a bug if you run into issues with existing polyfills. We may be
    able to add the polyfill directly to the NDK.

  • Issue 2100: Raised minimum required CMake version of the NDK's toolchain
    file from 3.6.0 to 3.10.0 to address warnings from new versions of CMake about
    upcoming loss of compatibility with versions older than 3.10.

Announcements

  • Android V will allow OEMs to ship arm64-v8a devices with 16KiB page sizes.
    Devices that use this configuration will not be able to run existing apps that
    use native code. To be compatible with these devices, applications will need
    to rebuild all their native code to be 16KiB aligned, and rewrite any code
    which assumes a specific page size. ndk-build and CMake have options to enable
    this mode (see note about APP_SUPPORT_FLEXIBLE_PAGE_SIZES and
    ANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES below). A future version of the NDK will
    enable this mode by default. If you're using or maintaining a third-party
    build system, consult the build system maintainers guide for instructions.

    See Support 16 KB page sizes for more information.

r27c

  • Updated LLVM to clang-r522817c. See clang_source_info.md in the toolchain
    directory for version information.
    • Issue 2040: Further fixes for miscompiles of indirect gotos.
    • Issue 2064: Fix HWAsan miscompilation.
    • Issue 2070: Fix crash in instantiation of function definitions.
    • Issue 2084: Fix for incorrect compiler error on overloaded member
      functions with ref-qualifiers.

r27b

  • Updated LLVM to clang-r522817b. See clang_source_info.md in the toolchain
    directory for version information.
    • Issue 2040: Fixed miscompile with indirect gotos.
    • Issue 2054: Fixed crash in x86 fp16 instruction selection.
    • Issue 2059: Fixed infinite loop in aarch64 vector instruction selection.
  • Issue 2032: Fixed compatibility issues with projects that used a very old
    cmake_minimum_required version ("Policy CMP0057 is not set: Support new
    IN_LIST if() operator").
  • Issue 2039: Fixed LOCAL_STRIP_MODE not being reset by
    include $(CLEAR_VARS).
  • Issue 2049: Restored metadata used by CMake in non-toolchain-file use cases
    that used CMAKE_SYSTEM_PROCESSOR instead of CMAKE_ANDROID_ARCH_ABI. If you
    ran into this problem, you should switch to using CMAKE_ANDROID_ARCH_ABI
    because that's what CMake's docs say to use. Better still, use the NDK's
    toolchain file.

Changes

  • Updated LLVM to clang-r522817. See clang_source_info.md in the toolchain
    directory for version information.
    • Issue 1728: Clang now emits an error for invalid Android target versions.
    • Issue 1853: clang-scan-deps is now included.
    • Issue 1911: Fixed inconsistent std::regex_replace results.
    • Issue 1947: Improved support for AArch64 function multi-versioning in clang.
    • Issue 1963: Fixed undefined behavior in std::unexpected::has_value().
    • Issue 1988: Added aarch64 support for preserve_all calling convention.
    • Issue 2007: Fixed crash in class template argument deduction caused by
      self-referential friend declaration.
    • Issue 2010: Removed superfluous libraries to reduce disk use.
    • Issue 2012: Fixed front end crash when using concepts and modules.
    • Issue 2013: Fixed false positive ODR violation in global module fragments.
    • Issue 2023: Fixed Clang crashes related to lambda captures in unevaluated
      contexts.
    • Issue 2024: Removed invalid __attribute__((__const__)) from gettid.
  • A RISC-V sysroot (AKA riscv64, or rv64) has been added. It is not
    supported. It is present to aid bringup for OS vendors, but it's not yet a
    supported Android ABI. It will not be built by default.
  • Issue 1856: Target-prefixed cmd wrappers for clang should now behave
    appropriately when the first argument includes quotes. You probably do not
    need to use those wrappers.     In most cases where you would use
    aarch64-linux-android21-clang, you can instead use clang -target aarch64-linux-android21, e.g. CC="clang -target aarch64-linux-android21" ./configure. The wrappers are only needed when working with systems that do
    not properly handle a CC that includes arguments.
  • Issue 1898: ndk-stack now tolerates 0x prefixed addresses.
  • Issue 1921: ANDROID_USE_LEGACY_TOOLCHAIN_FILE value is now preserved
    during try-compile steps when ON.
  • Issue 1974: Unintentionally shipped Vulkan headers have been removed from
    sources/third_party/vulkan. The standard Vulkan headers are included in the
    Android sysroot, which Clang will find automatically.
  • Issue 1993: ndk-stack now tolerates invalid UTF-8 characters in the trace.
  • Issue 1994: Fixed ndk-gdb/ndk-lldb to use the correct path for
    make and other tools.
  • Added APP_SUPPORT_FLEXIBLE_PAGE_SIZES for ndk-build and
    ANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES for CMake. Set to
    APP_SUPPORT_FLEXIBLE_PAGE_SIZES := true in your Application.mk or pass
    -DANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES=ON to CMake (via
    android.defaultConfig.externalNativeBuild.cmake.arguments if you're using
    the Android Gradle Plugin) to build your code to be compatible with devices
    that use a 16KiB page size. Third-party build system users and maintainers
    should consult the build system maintainers guide.
  • Symlinks are now properly preserved in the macOS App Bundle. The NDK installed
    via that method is now the same size as the one installed via the SDK manager.
  • The unsupported libclang, libclang-cpp, libLLVM, and libLTO libraries were
    removed to save space.

  • Issue 2049: Restored metadata used by CMake in non-toolchain-file use cases
    that used CMAKE_SYSTEM_PROCESSOR instead of CMAKE_ANDROID_ARCH_ABI. If you
    ran into this problem, you should switch to using CMAKE_ANDROID_ARCH_ABI
    because that's what CMake's docs say to use. Better still, use the NDK's
    toolchain file.

Changes

  • Updated LLVM to clang-r522817. See clang_source_info.md in the toolchain
    directory for version information.
    • Issue 1728: Clang now emits an error for invalid Android target versions.
    • Issue 1853: clang-scan-deps is now included.
    • Issue 1911: Fixed inconsistent std::regex_replace results.
    • Issue 1947: Improved support for AArch64 function multi-versioning in clang.
    • Issue 1963: Fixed undefined behavior in std::unexpected::has_value().
    • Issue 1988: Added aarch64 support for preserve_all calling convention.
    • Issue 2007: Fixed crash in class template argument deduction caused by
      self-referential friend declaration.
    • Issue 2010: Removed superfluous libraries to reduce disk use.
    • Issue 2012: Fixed front end crash when using concepts and modules.
    • Issue 2013: Fixed false positive ODR violation in global module fragments.
    • Issue 2023: Fixed Clang crashes related to lambda captures in unevaluated
      contexts.
    • Issue 2024: Removed invalid __attribute__((__const__)) from gettid.
  • A RISC-V sysroot (AKA riscv64, or rv64) has been added. It is not
    supported. It is present to aid bringup for OS vendors, but it's not yet a
    supported Android ABI. It will not be built by default.
  • Issue 1856: Target-prefixed cmd wrappers for clang should now behave
    appropriately when the first argument includes quotes. You probably do not
    need to use those wrappers.     In most cases where you would use
    aarch64-linux-android21-clang, you can instead use clang -target aarch64-linux-android21, e.g. CC="clang -target aarch64-linux-android21" ./configure. The wrappers are only needed when working with systems that do
    not properly handle a CC that includes arguments.
  • Issue 1898: ndk-stack now tolerates 0x prefixed addresses.
  • Issue 1921: ANDROID_USE_LEGACY_TOOLCHAIN_FILE value is now preserved
    during try-compile steps when ON.
  • Issue 1974: Unintentionally shipped Vulkan headers have been removed from
    sources/third_party/vulkan. The standard Vulkan headers are included in the
    Android sysroot, which Clang will find automatically.
  • Issue 1993: ndk-stack now tolerates invalid UTF-8 characters in the trace.
  • Issue 1994: Fixed ndk-gdb/ndk-lldb to use the correct path for
    make and other tools.
  • Added APP_SUPPORT_FLEXIBLE_PAGE_SIZES for ndk-build and
    ANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES for CMake. Set to
    APP_SUPPORT_FLEXIBLE_PAGE_SIZES := true in your Application.mk or pass
    -DANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES=ON to CMake (via
    android.defaultConfig.externalNativeBuild.cmake.arguments if you're using
    the Android Gradle Plugin) to build your code to be compatible with devices
    that use a 16KiB page size. Third-party build system users and maintainers
    should consult the build system maintainers guide.
  • Symlinks are now properly preserved in the macOS App Bundle. The NDK installed
    via that method is now the same size as the one installed via the SDK manager.
  • The unsupported libclang, libclang-cpp, libLLVM, and libLTO libraries were
    removed to save space.

Report issues to GitHub.

For Android Studio issues, go to https://b.android.com and file a bug using the
Android Studio component, not the NDK component.

If you're a build system maintainer that needs to use the tools in the NDK
directly, see the build system maintainers guide.

Announcements

  • Android V will allow OEMs to ship arm64-v8a devices with 16KiB page sizes.
    Devices that use this configuration will not be able to run existing apps that
    use native code. To be compatible with these devices, applications will need
    to rebuild all their native code to be 16KiB aligned, and rewrite any code
    which assumes a specific page size. ndk-build and CMake have options to enable
    this mode (see note about APP_SUPPORT_FLEXIBLE_PAGE_SIZES and
    ANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES below). A future version of the NDK will
    enable this mode by default. If you're using or maintaining a third-party
    build system, consult the build system maintainers guide for instructions.
