Changelog r27
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.

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
andANDROID_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.
- 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.
- 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 byinclude $(CLEAR_VARS)
. -
Issue 2049: Restored metadata used by CMake in non-toolchain-file use cases
that used
CMAKE_SYSTEM_PROCESSOR
instead ofCMAKE_ANDROID_ARCH_ABI
. If you ran into this problem, you should switch to usingCMAKE_ANDROID_ARCH_ABI
because that's what CMake's docs say to use. Better still, use the NDK's toolchain file.
- 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__))
fromgettid
.
- 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 useclang -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 aCC
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 whenON
. -
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 andANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES
for CMake. Set toAPP_SUPPORT_FLEXIBLE_PAGE_SIZES := true
in yourApplication.mk
or pass-DANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES=ON
to CMake (viaandroid.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.
